Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS supports ongoing replication and can migrate large databases with minimal downtime. Option A (AWS Direct Connect) provides dedicated network but is not a migration service. Option C (AWS Snowball) is for offline data transfer, not incremental sync. Option D (Amazon S3 Transfer Acceleration) speeds up uploads but does not handle database replication.

Answer

AWS Direct Connect

Answer

AWS Snowball

Answer

Amazon S3 Transfer Acceleration

Question 2

An organization is planning to migrate an SAP ERP system from on-premises to AWS. The system uses a custom ABAP application that has a hardcoded IP address for RFC connections. The migration strategy must minimize changes to the application. What is the MOST effective approach?

Accepted Answer

Assign an Elastic IP address to the SAP instance. Using an Elastic IP (Option D) ensures the public IP remains the same after migration, avoiding application changes. Option A (NAT Gateway) is for outbound traffic, not a fixed IP. Option B (VPC Peering) does not provide a fixed IP. Option C (DNS name) would require application changes.

Answer

Use a NAT Gateway to provide a fixed IP

Answer

Use VPC Peering to connect on-premises to AWS

Answer

Use a DNS name and update the application to use the DNS name

Question 3

A company is migrating an SAP system to AWS. They want to use AWS Launch Wizard to deploy SAP. Which TWO prerequisites are required for using Launch Wizard? (Choose TWO.)

Accepted Answer

An EC2 key pair for SSH access to the SAP instances. AWS Launch Wizard for SAP requires an EC2 key pair to enable SSH access to the SAP instances for initial configuration and troubleshooting. Without a key pair, you cannot securely connect to the instances after deployment, which is a fundamental prerequisite for any EC2-based deployment.

Answer

AWS Direct Connect connection to on-premises

Answer

An AWS Organization with all features enabled

Answer

A subscription to SAP software in AWS Marketplace

Question 4

A company is migrating a SAP system running on IBM AIX to AWS. Which TWO AWS services can be used to capture the server configuration and replicate it in AWS?

Accepted Answer

AWS CloudFormation. Correct options are B and D. AWS Server Migration Service (SMS) can capture server configurations from on-premises and replicate them to AWS as AMIs. AWS CloudFormation can be used to model the infrastructure as code, which can include the server configuration. Option A (AWS Config) is for compliance auditing and resource inventory, not for migration. Option C (AWS OpsWorks) is for Chef/Puppet automation, not for direct migration. Option E (AWS CodeDeploy) is for application deployment, not server migration.

Answer

AWS Config

Answer

AWS OpsWorks

Answer

AWS CodeDeploy

Question 5

A company is migrating a critical SAP ERP system from on-premises to AWS. The system uses SAP ASE as its database. During the migration, the company must ensure minimal downtime and data consistency. They plan to use SAP HANA System Replication (HSR) for the database migration. Which AWS service should they use to achieve this?

Accepted Answer

Use AWS Direct Connect to establish a private connection between on-premises and AWS, then configure HSR over the private IP.. For migrating an SAP ASE database with minimal downtime and data consistency, a private, high-bandwidth, low-latency connection between on-premises and AWS is essential. AWS Direct Connect provides this private connectivity, enabling reliable replication using SAP ASE's native replication mechanisms (e.g., SAP ASE Replication Server or log shipping) over a stable network. Option C (ALB with static IP) is incorrect because SAP ASE does not use HSR; that is only for SAP HANA. Options B (Route 53) and D (Transit Gateway) do not offer the dedicated private line required for consistent replication.

Answer

Use Amazon Route 53 weighted routing to distribute traffic between the source and target databases.

Answer

Use an Application Load Balancer (ALB) with a static IP address as the HSR endpoint.

Answer

Use an AWS Transit Gateway to connect the on-premises network to the VPC hosting the target HANA instance.

Question 6

A company is migrating an SAP system that uses a custom ABAP application with a large number of background jobs. They want to ensure that job scheduling is not disrupted during migration. Which AWS service can help manage job scheduling in the cloud?

Accepted Answer

Re-establish job scheduling within the SAP system after migration. The question asks which AWS service can help manage job scheduling in the cloud, but the correct answer is not an AWS service. This is because none of the listed AWS services—Amazon CloudWatch Events, AWS Lambda, or AWS Batch—are suitable for managing SAP's complex job scheduling. CloudWatch Events and Lambda are capable of triggering simple tasks but cannot handle the intricate dependencies and chains of ABAP background jobs. AWS Batch is designed for batch computing, not for orchestrating SAP job streams. Therefore, the best practice is to re-establish job scheduling within the SAP system itself after migration, ensuring that all custom job chains are preserved and executed correctly. Option C is correct because it acknowledges that direct migration of SAP job scheduling to an AWS service is neither feasible nor recommended; instead, scheduling must be reconfigured within the SAP environment.

Answer

Amazon CloudWatch Events

Answer

AWS Lambda

Answer

AWS Batch

Question 7

A company is migrating their SAP environment using AWS Launch Wizard. Which THREE prerequisites must be met before using Launch Wizard for SAP deployment? (Choose 3)

Accepted Answer

An AWS account with appropriate permissions.. AWS Launch Wizard for SAP deployment requires an AWS account with appropriate permissions (A), a VPC configured with subnets (C), and IAM roles with permissions to create resources (E). While a pre-configured S3 bucket for SAP media is often recommended, it is not a strict prerequisite because the wizard can create a bucket if needed or use an existing one. An existing SAP license is not a prerequisite because the wizard supports bring-your-own-license (BYOL) scenarios. Therefore, the correct answers are A, C, and E.

Answer

A pre-configured Amazon S3 bucket for SAP media.

Answer

An existing SAP license.

Question 8

An AWS IAM policy is attached to a role used by an SAP migration tool (e.g., AWS Application Migration Service) for migrating an SAP system to AWS. The migration fails because the tool cannot create EC2 instances. What is the missing permission?

Accepted Answer

ec2:RunInstances [CORRECT]. The policy likely allows actions like Describe, Start, Stop, and volume operations for existing resources, but it does not include 'ec2:RunInstances', which is required for the SAP migration tool to provision new EC2 instances for the target SAP system. Without this permission, the migration cannot proceed.

Answer

ec2:DescribeImages [wrong]

Answer

ec2:AllocateAddress [wrong]

Answer

ec2:CreateVolume [wrong]

Question 9

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. They want to minimize downtime. Which AWS service should they use for the initial data load and ongoing replication?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) supports ongoing replication from Oracle to RDS Oracle, enabling minimal downtime migration. Option A is incorrect because AWS Schema Conversion Tool (SCT) is for schema conversion, not replication. Option C is incorrect because AWS Snowball is for large-scale data transfer, not continuous replication. Option D is incorrect because AWS DataSync is optimized for file storage, not databases.

Answer

AWS Schema Conversion Tool (SCT)

Answer

AWS Snowball

Answer

AWS DataSync

Question 10

A company is migrating an application to AWS and creates the IAM policy shown in the exhibit. The policy is attached to an IAM user responsible for managing EC2 instances. Which additional permission must be added to allow the user to create new EC2 instances?

Accepted Answer

ec2:RunInstances. The policy allows Describe, Start, and Stop actions but not RunInstances. Option A (ec2:RunInstances) is required to create instances. Option B (ec2:DescribeImages) is for viewing AMIs. Option C (ec2:CreateTags) is for tagging. Option D (ec2:AllocateAddress) is for Elastic IPs.

Answer

ec2:DescribeImages

Answer

ec2:CreateTags

Answer

ec2:AllocateAddress

Question 11

A company is migrating a critical SAP ERP system to AWS. The migration plan includes using SAP HANA as the database. The system is used by thousands of users and requires high availability with a Recovery Point Objective (RPO) of 15 minutes and Recovery Time Objective (RTO) of 1 hour. Which architecture should they implement on AWS?

Accepted Answer

Use SAP HANA system replication with an active standby instance in another Availability Zone. SAP HANA system replication in an active standby setup across Availability Zones provides automatic failover and meets the RPO of 15 minutes and RTO of 1 hour. This is the correct architecture for high availability. Option B (single EC2 instance with nightly snapshots) does not provide high availability as a failure would take hours to recover from snapshots. Option C (Multi-AZ RDS for SAP HANA) is not applicable because Amazon RDS does not support SAP HANA as a database engine. Option D (DMS for continuous replication) is designed for database migration, not for high availability.

Answer

Deploy a single EC2 instance with SAP HANA and take nightly snapshots

Answer

Use AWS Database Migration Service (DMS) for continuous replication

Answer

Use Amazon RDS for SAP HANA with Multi-AZ deployment

Question 12

A company is migrating its SAP environment to AWS. They need to choose the right storage for SAP HANA data and log volumes. Which two storage types are SAP HANA certified on AWS? (Choose TWO.)

Accepted Answer

Amazon EBS gp3 volumes. Amazon EBS gp3 (Option B) and io2 (Option D) are both certified for SAP HANA data and log volumes on AWS. Instance store volumes (Option A) are ephemeral and not recommended for persistent data. Amazon S3 (Option C) is object storage, not block storage, and is not certified for HANA data/logs. Amazon EFS (Option E) is file storage and is not supported for SAP HANA.

Answer

Instance store volumes

Answer

Amazon S3

Answer

Amazon EFS

Question 13

A mid-size company is migrating its SAP Business One on SAP HANA to AWS. The current system runs on a single server with 256 GB RAM and uses a local disk for HANA data. The company wants to minimize capital expenditure and operational overhead. They have already sized the target EC2 instance as an x1e.2xlarge (122 GB RAM) but later realized that SAP HANA requires at least 256 GB RAM for their workload. The migration deadline is in one week. The company has a limited budget and cannot change the instance type to a larger one due to procurement delays. They have an 8 TB EBS gp2 volume attached for HANA data, but it is not meeting performance requirements. The team proposes the following actions:

Option A: Increase the EBS volume size to 16 TB to improve IOPS.
Option B: Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data.
Option C: Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore.
Option D: Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA.

Which option is the best course of action considering the constraints?

Accepted Answer

Use an instance with instance store SSDs (e.g., i3en.2xlarge) to get high local I/O performance, and migrate using SAP HANA backup and restore. The best because it recommends using an instance with instance store SSDs. Although the option mentions i3en.2xlarge as an example, the team can select a larger instance in the same family (e.g., i3en.8xlarge with 256 GB RAM) to meet the memory requirement. SAP HANA backup and restore is a valid migration method. Options A and B do not resolve the memory constraint, and Option D keeps the undersized x1e.2xlarge (122 GB RAM), which is insufficient for the HANA workload.

Answer

Increase the EBS volume size to 16 TB to improve IOPS

Answer

Use Amazon FSx for NetApp ONTAP as the storage backend for HANA, as it provides high performance and is certified for SAP HANA

Answer

Switch to EBS io2 volumes with provisioned IOPS to meet performance requirements, and use AWS DMS to migrate the data

Question 14

A healthcare company is migrating its SAP Business Suite system to AWS. The system includes an SAP HANA database (1.5 TB) and an SAP NetWeaver application server. They plan to use SAP HANA System Replication (HSR) for the database and AWS Application Migration Service (MGN) for the application server. The network connection is AWS Direct Connect with 500 Mbps bandwidth. During a test migration, the HSR replication is working, but the MGN replication for the application server is extremely slow. The MGN console shows that the replication is progressing at only 10 Mbps. The source application server is a physical machine with a 300 GB disk, 60% utilized. The administrator has verified that there are no other applications consuming significant network bandwidth. Which action is most likely to improve the MGN replication speed?

Accepted Answer

Increase the bandwidth limit setting in the MGN agent configuration on the source server.. MGN uses a replication server in AWS. The source server may be throttled by the MGN agent's default bandwidth limit. Option A is correct because increasing the agent's bandwidth limit can improve speed. Option B is wrong because changing the staging area disk type on the source does not affect replication speed. Option C is wrong because the network bandwidth is 500 Mbps, higher than 10 Mbps, so network is not the bottleneck. Option D is wrong because changing the target instance type does not affect data transfer.

Answer

Change the target EC2 instance type to a larger size.

Answer

Request an increase in the Direct Connect bandwidth to 1 Gbps.

Answer

Change the staging area disk on the source server from HDD to SSD.

Question 15

A company is migrating an on-premises Oracle database to Amazon RDS for Oracle. The database size is 500 GB, and the network bandwidth between the on-premises data center and AWS is 100 Mbps. The migration must minimize downtime. Which AWS service should the company use for the initial data load?

Accepted Answer

AWS Database Migration Service (DMS). AWS DMS can perform a full load and then continuously replicate changes to minimize downtime. AWS Snowball is for large offline data transfer, but the network might be sufficient; however, DMS is the recommended migration service for databases. Option A (AWS Database Migration Service) is correct because it supports ongoing replication to reduce downtime. Option B (AWS Snowball) is for offline transfer, not minimal downtime with continuous replication. Option C (AWS S3 Transfer Acceleration) is for file transfers, not database migration. Option D (AWS Direct Connect) improves network but does not perform data migration.

Answer

AWS Snowball

Answer

AWS Direct Connect

Answer

AWS S3 Transfer Acceleration

Question 16

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size and has a 4-hour downtime window. Which AWS service should be used to transfer the initial data copy to AWS?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is an offline data transfer device that is physically shipped to the customer, loaded with data, and then returned to AWS. This avoids network bandwidth limitations and is ideal for large initial data copies (2 TB) within a tight 4-hour downtime window. Options B and D (Direct Connect, S3 Transfer Acceleration) rely on network transfer, which may not complete within the downtime. Option C (AWS DataSync) is for online transfers and better suited for smaller or ongoing syncs, not bulk offline transfer.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS DataSync

Answer

AWS Direct Connect

Question 17

A company is migrating its SAP BusinessObjects BI platform to AWS. They plan to use an SAP-certified AMI for the SAP BusinessObjects application server. Which instance type is SAP-certified for SAP BusinessObjects on AWS?

Accepted Answer

r5.xlarge. SAP publishes certified instance types for each SAP application. For SAP BusinessObjects, memory-optimized instances like r5 are certified. Option A (c5.2xlarge) is compute-optimized and not certified for SAP BusinessObjects. Option C (i3.4xlarge) is storage-optimized and not certified. Option D (t3.large) is burstable and not certified.

Answer

c5.2xlarge

Answer

i3.4xlarge

Answer

t3.large

Question 18

A company wants to migrate its SAP application to AWS and needs to ensure high availability for the SAP Central Services (ASCS). Which AWS feature should be used to achieve this?

Accepted Answer

Amazon Route 53 health checks with failover routing. Amazon Route 53 with health checks and failover routing can monitor the health of the primary SAP Central Services (ASCS) instance. If the primary fails, Route 53 automatically routes traffic to a secondary ASCS instance in another Availability Zone, ensuring high availability. Option A (Elastic Load Balancer) is not typically used for ASCS because ASCS requires a single active node and failover, not load distribution. Option B (Auto Scaling groups) is designed for scaling compute capacity horizontally, not for providing high availability for stateful services like ASCS. Option D (Amazon CloudFront) is a content delivery network and is not relevant for SAP ASCS failover.

Answer

Elastic Load Balancer (ELB)

Answer

Auto Scaling groups

Answer

Amazon CloudFront

Question 19

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?

Accepted Answer

Provision EBS volumes based on the logical size of the database. 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 C (using same physical size) is incorrect because deduplication reduces storage. Option A (compression at OS level) may not be effective. Option D (using S3) is not block storage.

Answer

Use OS-level compression on the EBS volumes

Answer

Provision EBS volumes with the same physical size as on-premises

Answer

Use Amazon S3 for database storage

Question 20

A company is migrating its SAP landscape to AWS and plans to use SAP HANA as the database. The HANA system requires high network throughput between application and database servers. Which EC2 placement strategy should be recommended?

Accepted Answer

Cluster placement group. For high network throughput between SAP HANA application and database servers, the recommended placement group is Cluster. Cluster placement groups place instances within the same rack, providing the lowest latency and the highest possible network throughput, which is critical for SAP HANA's in-memory database communication. Option A (No placement group) may result in variable performance. Option B (Partition placement group) is designed for large distributed systems requiring fault isolation across partitions, not for maximizing throughput. Option C (Spread placement group) provides fault isolation but at the cost of lower network throughput compared to Cluster, as instances are placed on distinct hardware and may have higher latency.

Answer

No placement group

Answer

Partition placement group

Answer

Spread placement group
