PAS-C01 Migration Practice Test 9 — 15 Questions

Question 1

A company is migrating its SAP BusinessObjects to AWS. The current on-premises deployment uses a Windows-based environment. Which AWS service should the company use to migrate the Windows servers?

Accepted Answer

AWS Application Migration Service (AWS MGN). AWS MGN is the recommended service for migrating Windows servers to AWS. Option A is wrong because AWS SCT is for schema conversion, not server migration. Option C is wrong because AWS DMS is for databases, not servers. Option D is wrong because AWS Server Migration Service (SMS) is deprecated.

Answer

AWS Schema Conversion Tool (AWS SCT)

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Server Migration Service (AWS SMS)

Question 2

A company is migrating its SAP HANA database to AWS. The database is 3 TB and runs on a dedicated physical server. The company wants to use a HANA-certified EC2 instance. Which instance type should the company choose?

Accepted Answer

x1e.32xlarge. The x1e.32xlarge instance is SAP HANA-certified and provides 1952 GB of memory, which is sufficient for a 3 TB HANA database when considering compression and overhead. The other options either lack sufficient memory or are not HANA-certified. Specifically, the i3.16xlarge (488 GB) is not HANA-certified for large instances, the m5.24xlarge (384 GB) has too little memory, and the r5.24xlarge (768 GB) also lacks the required capacity.

Answer

i3.16xlarge

Answer

m5.24xlarge

Answer

r5.24xlarge

Question 3

A company is migrating its SAP system to AWS and wants to use a high-availability setup for the database layer. Which AWS service should the company use to achieve automatic failover for SAP HANA?

Accepted Answer

Amazon Route 53 with health checks. Amazon Route 53 can be configured with DNS failover using health checks to automatically redirect traffic to a standby SAP HANA database in the event of a primary failure. Option A is wrong because Amazon CloudFront is a content delivery network, not relevant for database failover. Option B is wrong because Elastic Load Balancing is designed for distributing traffic across multiple instances, not for database layer failover. Option D is wrong because AWS Global Accelerator improves application performance by routing traffic over the AWS global network, but it does not provide automatic failover for SAP HANA.

Answer

Amazon CloudFront

Answer

Elastic Load Balancing (ELB)

Answer

AWS Global Accelerator

Question 4

A company is migrating its SAP ERP system to AWS and needs to ensure that the SAP license is compliant. The company has a production license for SAP ERP. What should the company do for licensing on AWS?

Accepted Answer

Use the existing SAP license under the Bring Your Own License (BYOL) model.. AWS supports the Bring Your Own License (BYOL) model for SAP, allowing the company to use its existing SAP ERP license on AWS. Option A is incorrect because SAP does not offer a free license for AWS. Option B is incorrect because while subscription licenses are available, the company already has a production license, so BYOL is the appropriate choice. Option C is incorrect because purchasing a new license is unnecessary when the existing license can be reused under BYOL.

Answer

Request a free SAP license for AWS from SAP.

Answer

Use a subscription-based SAP license from the AWS Marketplace.

Answer

Purchase a new SAP license for AWS.

Question 5

A company is migrating its SAP system to AWS. The system uses a custom ABAP program that writes to a local file system. Which TWO AWS services can the company use to provide a shared file system accessible to multiple EC2 instances?

Accepted Answer

Amazon FSx for Lustre. Options A and D are correct. Amazon EFS provides a NFS file system that can be mounted on multiple EC2 instances. Amazon FSx for Lustre is a high-performance file system that can be shared across multiple instances. Option B is wrong because Amazon RDS is a database service. Option C is wrong because Amazon S3 is object storage. Option E is wrong because Amazon EBS volumes can only be attached to one EC2 instance at a time.

Answer

Amazon RDS

Answer

Amazon S3

Answer

Amazon EBS

Question 6

A company is migrating its SAP HANA database to AWS. The migration requires minimal downtime and data consistency. Which THREE steps should the company take to achieve this?

Accepted Answer

Use AWS DMS with change data capture (CDC) for ongoing replication.. To achieve minimal downtime and data consistency when migrating an SAP HANA database to AWS, the company should: Use AWS DMS with change data capture (CDC) for ongoing replication (B), create the target HANA database and schema in advance (C), and perform a full load of the data using AWS DMS before enabling CDC (D). A full backup and restore (A) would cause downtime, and disabling logging (E) is incorrect as it would compromise data consistency and recovery.

Answer

Take a full backup of the source database and restore it on the target.

Answer

Disable all logging on the source database to reduce overhead.

Question 7

A company is planning to migrate its SAP NetWeaver system to AWS. Which TWO AWS services can be used to store the SAP transport directory?

Accepted Answer

Amazon EFS. Options B and C are correct. Amazon EFS provides a scalable NFS file system suitable for the SAP transport directory, while Amazon FSx for Windows File Server offers SMB file shares if needed. Option A is incorrect because Amazon S3 is object storage, not a file system. Option D is incorrect because Amazon RDS is a relational database service, not a shared file system. Option E is incorrect because Amazon EBS is block storage, which is not suitable for a shared transport directory across multiple instances.

Answer

Amazon S3

Answer

Amazon RDS

Answer

Amazon EBS

Question 8

A company is using AWS DMS to migrate an SAP database. The full load is complete, but the CDC latency is high. Which step should the company take to reduce latency?

Accepted Answer

Increase the compute capacity of the DMS replication instance.. Increasing the compute capacity of the DMS replication instance provides more resources to process CDC changes, reducing latency. Option B is incorrect because increasing the target database size does not directly affect DMS replication performance. Option C is incorrect because restarting the task does not address the underlying resource constraint and may cause temporary downtime. Option D is incorrect because disabling CDC would stop replication entirely, not reduce latency.

Answer

Increase the size of the target database instance.

Answer

Restart the DMS replication task.

Answer

Disable change data capture (CDC) on the source database.

Question 9

An SAP administrator is trying to run an AWS DMS replication task from an EC2 instance that has this IAM role. The task fails with an access denied error. What is the most likely cause?

Accepted Answer

The policy does not include permissions for dms:DescribeReplicationTasks.. The IAM policy attached to the EC2 instance role does not include permissions for the dms:DescribeReplicationTasks action. When the DMS replication task is started, the DMS service needs to describe the task status and list replication tasks, which requires this action. Without it, the API call fails with an access denied error. Although the policy includes dms:CreateReplicationTask and dms:StartReplicationTask, the absence of dms:DescribeReplicationTasks causes the failure. Option D correctly identifies this missing permission.

Answer

The EC2 instance role is not attached to the instance.

Answer

The S3 bucket name is incorrect.

Answer

The S3 actions require additional permissions for the bucket.

Question 10

A company is using this CloudFormation template to provision infrastructure for an SAP HANA migration. When the stack is created, the RDS instance fails to launch. What is the most likely reason?

Accepted Answer

Amazon RDS does not support the SAP HANA engine.. Amazon RDS does not support SAP HANA as a database engine. SAP HANA must be installed on EC2 instances or on bare metal. Option A is incorrect because the template references the InstanceType parameter correctly using the Ref function. Option B is incorrect because while db.x1e.2xlarge is a valid RDS instance class for some engines (e.g., SQL Server), it is not valid for a non-existent RDS engine; but the primary issue is that SAP HANA is not supported on RDS at all. Option C is incorrect because the AMI ID is not relevant; RDS does not use AMIs; the stack would fail before checking AMI.

Answer

The InstanceType parameter is not properly referenced.

Answer

The DBInstanceClass db.x1e.2xlarge is not valid.

Answer

The AMI ID is invalid.

Question 11

A company is migrating a large SAP HANA database to AWS. The database is 4 TB in size. They need to transfer the initial data with the least possible network usage and minimal impact on production. The data is stored on a network-attached storage (NAS) device. Which approach should they use?

Accepted Answer

Use AWS Snowball Edge to transfer data offline. AWS Snowball Edge is a physical appliance designed for offline data transfer, making it the optimal choice for transferring a 4 TB SAP HANA database with minimal network usage. It eliminates network bandwidth consumption and avoids impacting production systems. Option A (AWS CLI with multipart upload over AWS Direct Connect) still consumes network bandwidth. Option B (AWS DataSync over the internet) also uses network bandwidth and may be slower for large datasets. Option C (AWS DMS for continuous replication) is intended for ongoing replication and would use network resources and potentially impact production.

Answer

Use AWS CLI with multipart upload over AWS Direct Connect

Answer

Use AWS DataSync to transfer data over the internet

Answer

Use AWS Database Migration Service (DMS) for continuous replication

Question 12

A company is migrating an SAP ERP system to AWS. The SAP application runs on a Windows Server with an MSSQL database. The migration must be completed within a strict 4-hour downtime window. The current database is 500 GB. Which migration strategy should be used to meet the downtime requirement?

Accepted Answer

Use an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL. For migrating an SAP ERP system with MSSQL database to AWS within a 4-hour downtime window, using an SAP-certified backup/restore tool (e.g., Commvault) to restore to Amazon EC2 with MSSQL is the best approach. This method leverages native MSSQL backup and restore capabilities, which are optimized for large databases and can complete within the downtime window. Option A (SAP SWPM export/import) is typically slower and may exceed 4 hours. Option C (AWS DMS with ongoing replication) is not ideal because DMS may not fully support SAP-specific schemas and could introduce compatibility issues, and the cutover may not be faster than backup/restore. Option D (AWS CloudEndure Migration) is designed for server-level replication, not database-optimized transfer, and may not meet the strict time constraint.

Answer

Use SAP SWPM export/import to migrate the database

Answer

Use AWS DMS with ongoing replication, then cutover

Answer

Use AWS CloudEndure Migration to replicate the entire server

Question 13

A company is migrating an SAP NetWeaver system from on-premises to AWS. They plan to use the same SAP SID and keep the same hostname. The migration will be performed using SAP Software Provisioning Manager (SWPM) with the option 'System Rename' set to 'No'. What must be configured in the AWS environment to ensure the system functions correctly?

Accepted Answer

Ensure the same private IP address is assigned to the Amazon EC2 instance. The system uses the same hostname and SAP SID. To avoid reconfiguration, the Amazon EC2 instance must have the same private IP address as the on-premises hostname resolves to, or the hostname must be resolvable via DNS or /etc/hosts. Option B is incorrect because updating DNS records to point to a new public IP is unnecessary when the same private IP is used. Option C is incorrect because the same SAP SID is allowed and does not need to be changed. Option D is incorrect because assigning a different private IP would require updating hostname resolution, which defeats the purpose of keeping the same hostname.

Answer

Update the DNS records to point to the new public IP

Answer

Change the SAP SID to a new value

Answer

Assign a different private IP address to avoid conflicts

Question 14

A company is migrating an SAP S/4HANA system to AWS. The migration strategy involves using SAP HANA System Replication (HSR) to replicate the source HANA database to an EC2 instance running HANA. During the final cutover, the replication link breaks and the target database becomes inconsistent. What should the migration team do to recover?

Accepted Answer

Perform a full HSR initial snapshot from the source to the target. When the HSR link breaks and the target becomes inconsistent during cutover, the only reliable recovery method is to perform a full HSR initial snapshot from the source. This completely reinitializes the target database, ensuring consistency. Option A (restart HSR with a delta snapshot) is incorrect because it requires a consistent state to apply changes incrementally, which does not exist. Option C (restore from AWS Backup) is incorrect as it may not reflect the latest data and could cause data loss. Option D (use AWS DMS) is incorrect because AWS DMS does not fully support HANA-to-HANA replication for SAP workloads.

Answer

Restart HSR with a delta snapshot from the source

Answer

Restore the target database from an AWS Backup

Answer

Use AWS DMS to replicate remaining changes

Question 15

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?

Accepted Answer

Increase the source database transaction log size and enable log compression. Increasing instance size may help but does not address the root cause of log space. Option B is incorrect because disabling transaction logging is not feasible for a production database and would break replication. Option C is correct because increasing the source database's transaction log size and enabling log compression reduces log waits and helps DMS keep up with changes. Option D is incorrect because using multiple tasks may cause conflicts and is not a direct solution for latency caused by log retention issues.

Answer

Increase the size of the DMS replication instance

Answer

Disable transaction logging on the source database

Answer

Use multiple DMS tasks for parallel replication
