A media company is migrating its on-premises video processing infrastructure to AWS. The current infrastructure uses a custom application that splits video files into segments, transcodes them using FFmpeg, and assembles the final output. The application runs on a single server with 64 vCPUs and 256 GB RAM. The migration plan is to use AWS Batch with EC2 instances for the transcoding jobs. The video files are stored on an on-premises NAS and will be migrated to Amazon S3. The company needs to minimize latency for file access during migration and reduce the time to transfer initial data. The company has a 1 Gbps AWS Direct Connect connection. The total data volume is 500 TB. The migration window is 30 days. Which approach should the team use to transfer the initial data to S3 with the lowest latency and within the migration window?

A.Use AWS DataSync to transfer data over the Direct Connect connection in multiple concurrent tasks.
B.Use multiple AWS Snowball Edge devices to transfer the data in parallel, then copy from the devices to S3 using the Snowball client.
C.Use a single AWS Snowball Edge device and copy data incrementally.
D.Use S3 Transfer Acceleration to speed up transfers over the internet.
AnswerB

Snowball Edge devices provide physical transport, overcoming bandwidth limitations and ensuring the transfer completes within 30 days.

Why this answer

Option B is correct because AWS Snowball Edge devices provide a physical, high-bandwidth transfer method that bypasses network constraints entirely. With 500 TB of data and a 1 Gbps Direct Connect link, the theoretical maximum transfer over the network in 30 days is only ~324 TB (1 Gbps * 30 days * 86400 seconds/day / 8 bits per byte), which is insufficient. Multiple Snowball Edge devices in parallel can transfer the full 500 TB within the migration window without saturating the Direct Connect link, and the Snowball client efficiently copies data to S3 after the devices are returned.

Exam trap

The trap here is that candidates underestimate the bandwidth limitation of a 1 Gbps Direct Connect link over a 30-day window, assuming it can handle 500 TB, while failing to calculate the actual throughput (max ~324 TB) and ignoring that network overhead and contention further reduce effective transfer rates.

How to eliminate wrong answers

Option A is wrong because AWS DataSync over a 1 Gbps Direct Connect connection cannot transfer 500 TB within 30 days; the maximum achievable throughput is ~324 TB, and real-world overhead (protocol, retransmissions) reduces this further, making it impossible to meet the deadline. Option C is wrong because a single AWS Snowball Edge device has a usable storage capacity of up to 80 TB, which is insufficient for 500 TB, and incremental copying would require multiple shipments, exceeding the 30-day window. Option D is wrong because S3 Transfer Acceleration uses internet-based transfers over public endpoints, which would be slower and less reliable than Direct Connect, and it does not address the fundamental bandwidth limitation of 1 Gbps.

An administrator uses AWS Launch Wizard to deploy an SAP S/4HANA system with high availability. After deployment, they notice that only one database instance is created. What is the most likely reason?

A.The deployment encountered an error and only created one instance.
B.The instance class r5.8xlarge is not certified for HANA.
C.The HighAvailability parameter was set to false.
D.The Launch Wizard does not support HA for HANA.
AnswerA

A likely reason is a failure during the HA setup.

Why this answer

High availability for SAP HANA typically requires at least two nodes (primary and secondary). If only one is created, the HA configuration may have failed or the parameter was ignored. The backup retention and instance classes are correct.

A company is migrating SAP applications to AWS and needs to ensure that the migration complies with regulatory requirements for data encryption. Which TWO AWS services can be used to encrypt data at rest? (Choose TWO.)

Select 2 answers
A.AWS WAF
B.AWS Certificate Manager (ACM)
C.Amazon EBS encryption
D.AWS CloudHSM
E.AWS Key Management Service (KMS)
AnswersC, E

EBS encryption encrypts volumes at rest.

Why this answer

Amazon EBS encryption encrypts volumes at rest, and AWS KMS manages encryption keys. Option C is wrong because AWS Certificate Manager is for SSL/TLS certificates. Option D is wrong because AWS CloudHSM is for hardware security modules, but not directly for data at rest encryption of EBS.

Option E is wrong because AWS WAF is for web application firewall.

A company is migrating an SAP ERP system to AWS. They plan to use AWS Launch Wizard to deploy the SAP landscape. After running Launch Wizard, the deployment fails with an error indicating that the instance type is not available in the selected Availability Zone. What should the company do to resolve this issue?

A.Relaunch the deployment using a different Availability Zone in the same Region.
B.Create a new VPC with different subnets and rerun Launch Wizard.
C.Modify the AWS CloudFormation template generated by Launch Wizard to specify a different instance type.
D.Request a limit increase for the instance type from AWS Support.
AnswerA

Launch Wizard allows selecting multiple AZs; choose one where the instance type is available.

Why this answer

Launch Wizard allows specifying multiple Availability Zones. By selecting a different AZ where the instance type is available, the deployment can proceed. Modifying the template manually or using CloudFormation directly is not necessary as Launch Wizard provides this option.

A company is migrating a large-scale SAP environment to AWS. Which THREE AWS services can be used to optimize storage costs for SAP workloads? (Choose three.)

Select 3 answers
A.AWS Storage Gateway for on-premises caching
B.Amazon S3 Lifecycle policies to transition data
C.Amazon S3 Standard for all data
D.Amazon S3 Glacier for long-term backup
E.Amazon EBS Snapshots for incremental backups
AnswersB, D, E

Lifecycle policies move data to cheaper tiers.

Why this answer

Amazon S3 Lifecycle policies (Option B) allow you to automatically transition SAP backup and archival data from S3 Standard to lower-cost storage classes like S3 Standard-IA or S3 Glacier, reducing storage costs without manual intervention. This is critical for SAP workloads where large volumes of backup data accumulate over time and do not require immediate access.

Exam trap

The trap here is that candidates may confuse AWS Storage Gateway (a hybrid caching service) with a cost optimization tool for native AWS SAP workloads, or assume that S3 Standard is sufficient for all data without considering lifecycle transitions to lower-cost tiers like Glacier.

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that is not supported by AWS Database Migration Service (DMS). The company needs to minimize downtime and automate the migration as much as possible. Which approach should be used?

A.Use AWS Database Migration Service (DMS) with a custom endpoint.
B.Use AWS Application Migration Service (MGN) to replicate the entire server, including the database, to AWS.
C.Export the database as a flat file, upload to Amazon S3, and import into Amazon RDS.
D.Use AWS Snowball to transfer database backups, then restore in Amazon RDS.
AnswerB

MGN provides continuous replication, supports any database, and automates migration with minimal downtime.

Why this answer

AWS Application Migration Service (MGN) can replicate entire servers, including the operating system, applications, and the proprietary database, to AWS without requiring database-specific support. This minimizes downtime by using continuous block-level replication and automates the migration by converting the source server into a native AWS instance. Since AWS DMS does not support the proprietary database, MGN provides a viable path for migrating the entire workload as a whole.

Exam trap

The trap here is that candidates assume AWS DMS can handle any database via custom endpoints, but DMS requires the source database to be one of its supported engines for logical replication; custom endpoints only allow connecting to unsupported targets, not unsupported sources.

How to eliminate wrong answers

Option A is wrong because AWS DMS with a custom endpoint still requires the database to be supported by DMS for the replication engine to interpret the data; a custom endpoint cannot add support for an unsupported proprietary database engine. Option C is wrong because exporting a proprietary database as a flat file is often not feasible due to proprietary binary formats, and importing into Amazon RDS would require a compatible database engine, which the proprietary database is not. Option D is wrong because AWS Snowball is designed for large-scale offline data transfer, not for minimizing downtime; it involves shipping physical devices and does not automate the migration process, and restoring a proprietary backup into Amazon RDS is impossible if RDS does not support that database engine.

A retail company is migrating its SAP ERP system to AWS. The system includes an SAP HANA database (1 TB) and an SAP NetWeaver application server. The migration strategy is to use AWS Database Migration Service (DMS) for the database and then manually install the application server on an EC2 instance. The network connection is AWS Direct Connect with 1 Gbps bandwidth. During the migration, the DMS task for the database completes successfully, but the application server installation fails because the SAP installation media is not accessible. The installation media is stored on an on-premises file server. The EC2 instance for the application server is in a private subnet with no direct internet access. The administrator has created a VPC endpoint for S3 to access the media, but the media is not in S3. Which step should the administrator take to make the installation media available?

A.Copy the installation media to an S3 bucket and use the VPC endpoint to access it.
B.Add a route in the VPC route table to direct traffic to the on-premises network via Direct Connect.
C.Attach an internet gateway to the VPC and assign a public IP to the EC2 instance.
D.Use AWS Storage Gateway to cache the media in S3.
AnswerB

Enables the EC2 instance to reach the on-premises file server.

Why this answer

Since the media is on-premises, the EC2 instance needs access to the on-premises file server. Option A is correct because using Direct Connect, the private subnet can route to on-premises via the VPC route table. Option B is wrong because the media is not in S3.

Option C is wrong because the media is not on the internet. Option D is wrong because the media is not in S3.

A company is migrating a large SAP Business Suite system to AWS. The system has a 10 TB SAP HANA database. The migration window is limited to 48 hours. The company has a 1 Gbps direct connect link to AWS. Which TWO actions should the company take to minimize the migration time while ensuring data consistency?

Select 2 answers
A.Use AWS Snowball Edge to transfer a full database backup from on-premises to AWS, then restore it on the target HANA instance.
B.Set up SAP HANA System Replication (HSR) and let it synchronize the full database over the Direct Connect link.
C.Use AWS DMS to migrate the HANA database directly over the Direct Connect link.
D.After the initial restore from Snowball, configure SAP HANA System Replication to synchronize incremental changes.
E.Use AWS SCT to convert the database schema before migration.
AnswersA, D

Snowball accelerates initial data transfer.

Why this answer

Option A (initialize the target HANA instance with a backup/restore using AWS Snowball) is correct because it bypasses network limitations for the initial data load. Option D (configure SAP HANA System Replication over the Direct Connect link after initial load) is correct because it syncs incremental changes. Option B would take too long over the link.

Option C is for ongoing replication not initial load. Option E is a best practice but not for minimizing migration time.

An organization is migrating a legacy application to AWS. The application requires a static IP address for client whitelisting. After migrating the application to an Application Load Balancer (ALB) with an Auto Scaling group, clients report connection failures. What should be done to resolve this issue?

A.Place an Nginx reverse proxy in front of the ALB with an Elastic IP.
B.Assign an Elastic IP to the ALB.
C.Configure the ALB to use a round-robin routing algorithm.
D.Replace the ALB with a Network Load Balancer (NLB) and assign an Elastic IP.
AnswerD

NLB supports static IP via Elastic IP.

Why this answer

Option C is correct because an ALB does not have a static IP; using a Network Load Balancer (NLB) with an Elastic IP provides a static IP for whitelisting. Option A is wrong because an ALB cannot be assigned an Elastic IP. Option B is wrong because an ALB already distributes traffic.

Option D is wrong because an Nginx proxy adds complexity and still requires a static IP.

A.No placement group
B.Partition placement group
C.Spread placement group
D.Cluster placement group
AnswerC

Spread placement group ensures instances are on different hardware but in close proximity, providing low latency and high availability.

Why this answer

A placement group with spread strategy ensures instances are on different hardware but close together for low latency. Option B (cluster placement group) is for low latency but all instances on same rack, single point of failure. Option C (partition) is for large distributed systems.

Option D (no placement group) may introduce higher latency.

Which THREE considerations are important when planning the migration of an SAP HANA database to AWS using HANA System Replication (HSR)?

Select 3 answers
A.The target EC2 instance must have at least the same amount of RAM as the source.
B.The source and target must be in the same AWS Region.
C.The target storage must be able to accommodate the data volume.
D.The network latency between source and target must be less than 10 ms for synchronous replication.
E.The source database must be encrypted before replication can start.
AnswersA, C, D

HANA needs sufficient memory.

Why this answer

HSR requires network latency below 10 ms for synchronous replication, and the target instance must have sufficient memory and storage. Network bandwidth is important but not the only factor. The source and target can be in different Regions, but latency must be acceptable.

Encryption is not a prerequisite for HSR.

A.Amazon S3
B.Amazon FSx for Windows File Server
C.Amazon EFS
D.Amazon EBS
AnswerC

EFS provides NFS file system.

Why this answer

Option C is correct because Amazon EFS provides a scalable NFS file system that can be mounted on EC2 instances. The backup files can be copied from on-premises NFS to EFS using AWS DataSync or other methods, and then used for restore. Options A, B, D are incorrect because S3 is object storage (not NFS), FSx for Windows File Server is SMB, and EBS is block storage not NFS.

A company is migrating a legacy application to AWS that requires a static IP address for client whitelisting. The application will run on EC2 instances behind an Application Load Balancer (ALB). The company wants to ensure the IP address does not change over time. What should the company do?

A.Assign an Elastic IP to each EC2 instance
B.Use Route 53 latency-based routing to point to the ALB
C.Use AWS Global Accelerator to get two static IP addresses
D.Use a Network Load Balancer (NLB) with an Elastic IP address
AnswerD

NLB supports static IP via Elastic IP, which can be whitelisted.

Why this answer

Option D is correct because a Network Load Balancer (NLB) supports static IP addresses by allowing you to assign Elastic IPs directly to each of its Availability Zone subnets. This provides fixed IP endpoints for client whitelisting, while the NLB can forward traffic to the EC2 instances behind an ALB, preserving the application's architecture.

Exam trap

The trap here is that candidates often choose Global Accelerator because it offers static IPs, but they overlook that an NLB with Elastic IPs is the simpler, cost-effective solution for a single-region static IP requirement, and Global Accelerator is intended for global traffic acceleration, not just static IP assignment.

How to eliminate wrong answers

Option A is wrong because assigning Elastic IPs to EC2 instances would expose individual instance IPs, not a stable front-end IP for the ALB, and the instances are behind the ALB, so client whitelisting should target the load balancer's IP, not the instances. Option B is wrong because Route 53 latency-based routing resolves to the ALB's DNS name, which can change IP addresses over time, and does not provide static IP addresses. Option C is wrong because AWS Global Accelerator provides two static IP addresses, but it is designed for global traffic optimization and adds unnecessary complexity and cost; the question requires a simple static IP for whitelisting, which the NLB with Elastic IPs directly achieves.

A company is migrating its SAP ERP system (with Oracle database) to AWS using the SAP-certified approach. The current on-premises environment uses Oracle RAC for high availability. The company wants to reduce licensing costs and simplify the architecture on AWS. Which of the following is the MOST efficient migration strategy?

A.Use AWS DMS to migrate the database to Amazon RDS for Oracle, but then configure RDS for Oracle RAC.
B.Use AWS DataSync to copy the Oracle database files to EBS volumes, then restore on an EC2 instance.
C.Use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.
D.Lift-and-shift the Oracle RAC cluster to EC2 using AWS Application Migration Service.
AnswerC

This reduces licensing costs and simplifies the architecture. DMS supports Oracle as source and target RDS Oracle.

Why this answer

AWS does not support Oracle RAC in a fully supported manner for SAP. The best practice is to migrate to Amazon RDS for Oracle or use Oracle single instance on EC2. Using AWS DMS with ongoing replication can minimize downtime.

Option B is correct because it uses DMS and moves to RDS, which reduces licensing overhead. Option A uses RAC which is not recommended on AWS. Option C uses DMS but then keeps RAC, which is costly and unsupported.

Option D uses DataSync which is not for database replication.

A company is migrating a large-scale SAP HANA workload to AWS. The system requires high memory and low latency. Which EC2 instance type is most suitable for this migration?

A.x1e.32xlarge
B.m5.24xlarge
C.c5.18xlarge
D.r5.24xlarge
AnswerA

x1e instances are memory-optimized and SAP HANA certified.

Why this answer

The x1e.32xlarge is purpose-built for high-memory, SAP HANA workloads, offering up to 3,904 GiB of memory and high-speed NVMe SSD storage with low-latency networking. It is certified by SAP for running production HANA environments, making it the most suitable choice for this migration.

Exam trap

The trap here is that candidates often choose the r5 family (memory-optimized) thinking it is sufficient for SAP HANA, but they overlook the specific memory capacity requirements and SAP certification needed for large-scale workloads, which only the x1e instance meets.

How to eliminate wrong answers

Option B (m5.24xlarge) is wrong because it is a general-purpose instance with only 384 GiB of memory, insufficient for large-scale SAP HANA workloads that require terabytes of RAM. Option C (c5.18xlarge) is wrong because it is compute-optimized, designed for CPU-intensive tasks, not memory-intensive databases like SAP HANA. Option D (r5.24xlarge) is wrong because while it is memory-optimized, it provides only 768 GiB of memory, which is far below the x1e's capacity and not SAP HANA-certified for large-scale production deployments.

A company is migrating its on-premises web application to AWS. The application consists of a stateless web tier and a stateful database tier running on a single server. The web tier uses session data stored in the local file system. The database tier runs on MySQL. The company wants to minimize changes to the application code during migration. They plan to use Amazon EC2 for the web server and Amazon RDS for MySQL for the database. After migrating the web server to an EC2 instance and the database to RDS, users report that they are being logged out of the application frequently. What is the most likely cause of this issue?

A.The web server's session data is stored locally and is lost when the EC2 instance is replaced or restarted.
B.The RDS instance's backup window is causing database connections to drop.
C.The application's session timeout setting was reduced during migration.
D.The security group for the web server is blocking inbound session cookies.
AnswerA

Since the application stores sessions locally, any instance replacement leads to session loss.

Why this answer

The web tier stores session data in the local file system of the EC2 instance. When the instance is replaced or restarted (e.g., due to Auto Scaling, instance failure, or a maintenance event), that local session data is lost. Since the application code was not modified to use a shared session store (like ElastiCache or DynamoDB), users lose their sessions and are logged out.

This is the most likely cause because the migration explicitly minimized code changes and did not address the stateless web tier requirement.

Exam trap

The trap here is that candidates may assume session data is automatically preserved across EC2 instance lifecycles, or they may incorrectly blame RDS connectivity or security group rules, when the real issue is the lack of a shared, durable session store for the stateless web tier.

How to eliminate wrong answers

Option B is wrong because RDS backup windows do not cause database connections to drop; RDS remains available during backups (Multi-AZ or single-AZ with I/O suspension), and any brief I/O suspension would not cause web session loss. Option C is wrong because there is no evidence that the session timeout setting was changed; the problem is session data persistence, not timeout duration. Option D is wrong because security groups do not block inbound session cookies; security groups filter network traffic at the IP/port level, not application-layer HTTP cookies.

A company is migrating an SAP application server to AWS using CloudFormation. The template snippet is shown in the exhibit. The SAP application requires at least 300 GB of disk space for /usr/sap. Which change should be made to the template?

A.Change the instance type to a larger size to provide more instance storage.
B.Increase the root volume (/dev/xvda) size to 300 GB.
C.Increase the size of the second volume (/dev/xvdb) to 300 GB.
D.Add a third EBS volume of 100 GB for /usr/sap.
AnswerC

The second volume is likely for /usr/sap; increase to 300 GB.

Why this answer

The SAP application server typically needs a large disk for /usr/sap. The template currently has a 100 GB root volume and a 200 GB additional volume, total 300 GB. However, /usr/sap is usually mounted on a separate volume.

The 200 GB volume is likely for /usr/sap, but 200 GB may not be enough if the requirement is at least 300 GB. The correct action is to increase the second volume size to at least 300 GB. Increasing root volume or adding a third volume are alternatives but less direct.

D.AWS DataSync
AnswerC

DMS supports ongoing replication to minimize downtime.

Why this answer

AWS DMS can perform ongoing replication with minimal downtime. Option B is correct because it supports continuous data replication. Option A is wrong because AWS SMS is for server migration.

CloudWatch logs provide detailed error messages for troubleshooting.

Why this answer

Option D is correct because the first step is to check the CloudWatch logs for DMS to find detailed error messages. Option A is wrong because restarting without investigation may lead to the same error. Option B is wrong because modifying table mappings may not be the issue.

Option C is wrong because creating a new task without understanding the failure is inefficient.

A company is migrating its SAP HANA database from on-premises to AWS. The current system uses 6 TB of memory and the company wants to minimize downtime. The company has established a 10 Gbps AWS Direct Connect connection. Which migration method is MOST suitable?

A.Perform a full SAP HANA backup to the on-premises storage, copy the backup files to Amazon S3 using AWS Direct Connect, and restore on AWS.
B.Set up SAP HANA system replication between on-premises and AWS, then perform a takeover.
C.Use AWS Database Migration Service (AWS DMS) with full load plus ongoing replication.
D.Use AWS Snowball Edge to physically transport the backup files to AWS and then restore.
AnswerA

Backup and restore over Direct Connect is efficient for large databases and minimizes downtime during restore.

Why this answer

SAP HANA backup and restore is the most common method for large databases; using AWS Direct Connect speeds up the transfer. Option A is wrong because DMS does not support SAP HANA as a source. Option B is wrong because SAP HANA system replication requires low latency and is not ideal for one-time migration.

Option D is wrong because AWS Snowball would introduce additional logistics and potential delays.

A company is migrating a production SAP HANA database to AWS. The database size is 2 TB. The migration window is 4 hours. The network bandwidth is 10 Gbps. Which migration method should be used to achieve the shortest downtime?

A.Use a backup and restore approach.
B.Use AWS DMS with full load and CDC.
C.Use SAP HANA System Replication.
D.Use AWS Snowball Edge for initial load, then CDC.
AnswerC

System Replication provides the shortest downtime, often minutes.

Why this answer

SAP HANA System Replication can achieve near-zero downtime if network latency and bandwidth are adequate. With 10 Gbps, initial sync can be fast. Backup/restore would exceed 4 hours.

B.Disable HSR preload on the target
C.Use AWS Global Accelerator to route traffic over the AWS global network
D.Increase the HSR timeout values significantly

A company is migrating a legacy application to AWS. The application currently uses Oracle Database and the company wants to migrate to Amazon Aurora PostgreSQL with minimal downtime. Which TWO steps should be taken to achieve this? (Choose TWO)

Select 2 answers
A.Use the AWS Schema Conversion Tool (SCT) to convert the Oracle schema to PostgreSQL.
B.Rehost the Oracle database on an Amazon EC2 instance to minimize changes.
C.Configure Amazon Aurora PostgreSQL with Multi-AZ for high availability.
D.Use AWS Database Migration Service (DMS) with ongoing replication (change data capture).
E.Export Oracle database as dump files and import into Aurora PostgreSQL using native tools.
AnswersA, D

SCT automates the conversion of Oracle schema objects to PostgreSQL-compatible format.

Why this answer

Option A is correct because the AWS Schema Conversion Tool (SCT) can automatically convert Oracle database schemas (including stored procedures, views, and data types) to a PostgreSQL-compatible format, which is essential when migrating to Amazon Aurora PostgreSQL. Option D is correct because AWS DMS with ongoing replication (change data capture) allows you to keep the source Oracle database and target Aurora PostgreSQL synchronized with minimal downtime, enabling a near-zero-downtime migration by capturing and applying incremental changes.

Exam trap

The trap here is that candidates often confuse 'migration steps' with 'post-migration configuration' (like Multi-AZ) or assume that a simple dump-and-load approach (Option E) can achieve minimal downtime, when in fact it requires a full outage, whereas DMS with CDC is the correct AWS-native approach for near-zero-downtime migrations.

The network connection is AWS Direct Connect with 1 Gbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for one of the application servers is failing with an error: "The agent cannot communicate with the MGN service endpoint." The source server is a Windows Server 2016 machine. The administrator has verified that the source server has internet connectivity. Which action is most likely to resolve the issue?

A.Reinstall the MGN agent on the source server.
B.Configure an HTTP proxy on the source server to route traffic through the corporate proxy.
C.Create a VPC endpoint for AWS Application Migration Service in the source VPC.
D.Change the source server's OS to Linux.

A company is migrating a multi-tier application to AWS. The application includes a load balancer, web servers, and an Oracle database. The migration plan includes using AWS DMS for the database. During the initial full load, the DMS task fails with an error indicating insufficient memory. The source database is on an EC2 instance with 4 GB RAM. What should the migration team do to resolve this issue?

A.Disable LOB support in the DMS task
B.Split the migration into multiple smaller tasks
C.Increase the size of the DMS replication instance
D.Increase the memory of the source EC2 instance
AnswerC

More memory on the replication instance can handle large data loads.

Why this answer

Option C is correct because the error 'insufficient memory' during the initial full load in AWS DMS typically indicates that the replication instance does not have enough memory to handle the data volume or LOB processing. Increasing the size of the DMS replication instance provides more memory for caching, transformation, and LOB handling, directly resolving the resource constraint without altering the source database or task structure.

Exam trap

The trap here is that candidates may mistakenly think the error refers to the source database's memory (Option D) or that disabling LOBs (Option A) is a quick fix, when in fact the DMS replication instance's memory is the bottleneck and must be scaled up.

How to eliminate wrong answers

Option A is wrong because disabling LOB support would prevent the migration of Large Objects, which may be required for the Oracle database, and the error is about insufficient memory, not LOB configuration. Option B is wrong because splitting the migration into multiple smaller tasks does not address the root cause of insufficient memory on the replication instance; it only reduces the data per task but still requires adequate memory for each task. Option D is wrong because the source EC2 instance's memory (4 GB RAM) is not the limiting factor; AWS DMS runs on a separate replication instance, and the error originates from the DMS task, not the source database host.

A company is migrating an SAP system to AWS using the SAP Landscape Reorganization (LaMa) tool. Which TWO actions can LaMa perform during the migration?

Select 2 answers
A.Perform a heterogeneous system copy.
B.Migrate SAP systems from on-premises to AWS with minimal downtime.
C.Convert the source database from Oracle to SAP HANA.
D.Provision AWS EC2 instances and storage automatically.
E.Automatically update DNS records after migration.
AnswersB, D

LaMa orchestrates the migration process.

Why this answer

LaMa is designed to orchestrate system migrations with minimal downtime by automating the cloning and replication process. It uses storage-level snapshots or database replication to keep the source system running until the final cutover, which is why Option B is correct.

Exam trap

The trap here is confusing LaMa's homogeneous copy capability with heterogeneous migration or database conversion, leading candidates to select A or C, which require separate tools not part of LaMa's feature set.

A company is migrating an SAP Business Warehouse (BW) system running on an on-premises HANA database to AWS. The migration must be completed with less than 1 hour of downtime. The source database is 3 TB. The company has established a 10 Gbps AWS Direct Connect connection. The SAP system uses a custom ABAP program that must be migrated as well. The company wants to minimize manual intervention. Which approach should be taken?

A.Use AWS DMS to replicate the HANA database to Amazon RDS for HANA.
B.Set up SAP HANA System Replication (HSR) to replicate the database to AWS, then perform a takeover.
C.Export the HANA database to files, transfer via Direct Connect, and import on EC2.
D.Use AWS Application Migration Service (MGN) to replicate the entire server.
AnswerB

HSR provides synchronous replication with minimal downtime.

Why this answer

Using SAP HANA System Replication (HSR) allows near-zero downtime replication. Option B is wrong because AWS DMS does not support HANA as a source for ongoing replication without schema conversion. Option C is wrong because AWS MGN is for server migration, not database.

Option D is wrong because manual restore would exceed downtime.

Refer to the exhibit. An administrator is trying to restore an SAP HANA backup from an S3 bucket but receives an AccessDenied error. The administrator has full EC2 and S3 permissions via an IAM role attached to the EC2 instance. What is the most likely cause?

A.The S3 bucket is in a different region than the EC2 instance
B.The backup file is encrypted with SSE-C and the key is not provided
C.The administrator used the wrong S3 command syntax
D.The S3 bucket has a bucket policy that denies access from the instance's IAM role
AnswerD

A bucket policy can explicitly deny access even if IAM allows.

Why this answer

The error indicates the S3 bucket policy likely denies access. Option A (incorrect region) would give a different error. Option B (KMS key) possible but less likely than bucket policy.

Option C (incorrect command) not likely. Option D (missing encryption) not relevant.

A company is migrating an SAP Business Suite system to AWS. They are using AWS DMS to replicate data from the on-premises SAP ASE database to Amazon RDS for SAP ASE. After the initial load, the ongoing replication shows a latency of several hours. The source database is heavily used. Which action should the migration team take to reduce replication latency?

A.Increase the size of the DMS replication instance
B.Disable transaction logging on the source database
C.Increase the source database transaction log size and enable log compression
D.Use multiple DMS tasks for parallel replication
AnswerC

Larger log files and compression reduce log waits and improve replication throughput.

Why this answer

Option A is incorrect because increasing instance size may help but not address the root cause of log space. Option B is incorrect because using multiple tasks may cause conflicts. Option C is correct because increasing the source database's transaction log size and enabling log compression reduces log waits.

Option D is incorrect because disabling logging is not feasible for production.

A company is migrating an SAP system to AWS. They need to ensure high availability for the SAP Central Services (ASCS/ERS). Which THREE components are required for a highly available SAP ASCS/ERS setup on AWS? (Choose THREE.)

Select 3 answers
A.A cluster manager (e.g., Pacemaker)
B.An Application Load Balancer
C.Amazon Route 53 health checks
D.Shared file system (e.g., Amazon FSx or EFS)
E.Elastic IP address for the virtual IP
AnswersA, D, E

Cluster manager orchestrates failover of ASCS/ERS.

Why this answer

For HA SAP ASCS/ERS, you need a cluster (Option A), shared storage (Option B), and Elastic IP for VIP (Option D). Option C (ELB) is not used for ASCS/ERS. Option E (Route 53) is optional for DNS.

A company is migrating its SAP environment to AWS and wants to test the migration process before the final cutover. The company has a limited budget for the test environment. Which approach is MOST cost-effective?

A.Use AWS Database Migration Service (AWS DMS) to continuously replicate the database to a smaller RDS instance for testing.
B.Use AWS Elastic Disaster Recovery to replicate the on-premises servers to a staging area and launch test instances in a sandbox VPC.
C.Provision a full production-sized infrastructure in a separate AWS account and use AWS DMS to replicate the database.
D.Use AWS Migration Hub to track the migration progress and perform a trial migration using AWS CloudFormation templates.
AnswerB

AWS Elastic Disaster Recovery provides a cost-effective way to test migration with non-production instances.

Why this answer

AWS Elastic Disaster Recovery allows quick, cost-effective testing by replicating the source and launching instances in a sandbox network. Option A is wrong because spinning up full production-sized instances is expensive. Option B is wrong because AWS DMS is for databases, not full systems.

Option D is wrong because AWS Migration Hub orchestrates but doesn't provide a sandbox environment for testing.

A company is migrating an SAP system to AWS and wants to monitor the performance of the SAP application servers. Which TWO AWS services can be used to collect and analyze SAP performance metrics?

Select 2 answers
A.AWS CloudTrail
B.AWS Systems Manager
C.Amazon CloudWatch with SAP monitoring agent
D.Amazon Inspector
E.AWS X-Ray
AnswersB, C

Systems Manager can run commands and collect OS metrics, complementing SAP monitoring.

Why this answer

Amazon CloudWatch can collect custom metrics, and AWS CloudTrail logs API calls but does not monitor performance. AWS X-Ray traces requests. Amazon Inspector is for security.

AWS Systems Manager can collect OS-level metrics but not SAP-specific. CloudWatch with SAP monitoring agent is a common solution. Option A (CloudTrail) is incorrect.

Option D (Inspector) is for security.

A company is migrating an SAP HANA system to AWS using a homogeneous copy. The source database is SAP HANA 2.0 on SUSE Linux, and the target is also SAP HANA 2.0 on AWS. Which AWS service can be used to transfer the HANA backup files to Amazon S3 efficiently?

A.AWS DataSync
B.AWS Storage Gateway
C.AWS Direct Connect
D.Amazon S3 Transfer Acceleration
AnswerA

DataSync is designed for efficient, secure data transfer to S3.

Why this answer

AWS DataSync can efficiently transfer large files to S3. Option A (AWS Storage Gateway) is for hybrid storage. Option B (AWS DataSync) is correct.

Option C (AWS S3 Transfer Acceleration) speeds up S3 uploads but is not a managed transfer service like DataSync. Option D (AWS Direct Connect) is a network connection.

A company is migrating its SAP ERP system running on Oracle Database to SAP HANA on AWS. The current on-premises environment has a 5 TB Oracle database with high transaction volume. The migration must be completed within a 4-hour downtime window. The target environment on AWS uses an SAP-certified instance with 1 TB of RAM. The company has a 1 Gbps AWS Direct Connect connection. The migration team is considering using SAP DMO with SUM. However, during a test run, the database export took 6 hours, exceeding the downtime window. What should the migration team do to meet the 4-hour downtime window?

A.Perform a system copy to an Oracle database on AWS first, then migrate to HANA
B.Use the SAP HANA Database Migration Option (DMO) with the 'load and move' method
C.Upgrade to a larger EC2 instance type with more CPU and memory for the HANA database
D.Use AWS Snowball Edge to transfer the initial data and then perform a delta sync
AnswerB

DMO with 'load and move' allows pre-loading data before the downtime window, reducing the downtime to a delta transfer.

Why this answer

Option C is correct because using the SAP HANA Database Migration Option (DMO) with the 'load and move' approach allows initial data load during the migration preparation phase and then only a delta transfer during the downtime window, reducing downtime. Option A is wrong because a larger instance may speed up processing but the export time is limited by the network (1 Gbps). Option B is wrong because AWS Snowball would add time for shipping and data transfer, likely exceeding the window.

Option D is wrong because a homogenous migration to another Oracle database does not address the requirement to migrate to HANA.

During a migration of an SAP system to AWS, the team discovers that the on-premises storage uses a proprietary deduplication technology. The SAP database will be migrated to Amazon EBS volumes. How should the team address the storage space requirements on AWS?

A.Use OS-level compression on the EBS volumes
B.Provision EBS volumes based on the logical size of the database
C.Provision EBS volumes with the same physical size as on-premises
D.Use Amazon S3 for database storage
AnswerB

The logical size represents the actual data; EBS volumes should match that.

Why this answer

AWS does not support proprietary deduplication. The team should provision EBS volumes based on the logical size of the database after verifying the actual data size. Option A (using same physical size) is incorrect because deduplication reduces storage.

Option C (compression at OS level) may not be effective. Option D (using S3) is not block storage.

An organization is migrating a large SAP ERP system using SAP Landscape Virtualization Management (LVM) for system copy and refresh. During the migration, they encounter an error in LVM indicating that the target host is not reachable. What is the most likely cause?

A.The S3 bucket used for backup is not accessible.
B.The IAM role assigned to the LVM instance does not have sufficient permissions.
C.The AWS Database Migration Service is not configured correctly.
D.The security groups do not allow inbound traffic from the LVM instance to the target host.
AnswerD

Security groups control traffic; if not configured, the target is unreachable.

Why this answer

Security groups controlling traffic between source and target are a common cause. IAM roles affect AWS API calls, not network connectivity. S3 permissions are irrelevant.

AWS DMS is not used.
