PAS-C01 Migration Practice Test 5 — 15 Questions

Question 1

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?

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

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 2

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 the source database transaction log size and enabling log compression can reduce replication latency by preventing log truncation and improving log read efficiency. AWS DMS reads the transaction log to capture changes; if the log is too small, it may truncate before DMS reads it, causing latency. A larger log and compression help DMS keep up with the change stream.

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

Question 3

A company is migrating an SAP HANA database using SAP HANA System Replication (HSR) to AWS. The target EC2 instance is in a different AWS Region than the source. The network latency between regions is high. What should the migration team configure to ensure successful replication?

Accepted Answer

Use AWS Global Accelerator to route traffic over the AWS global network. A VPN connection adds overhead and latency over the internet, worsening replication issues. Option B is incorrect because disabling HSR preload reduces memory usage but does not address high latency; it may even increase recovery time. Option C is correct because AWS Global Accelerator uses the AWS global network to optimize routing, reducing latency impact for HSR replication. Option D is incorrect because increasing HSR timeout values only masks timeout symptoms without resolving the underlying latency problem.

Answer

Set up a VPN connection to the target region

Answer

Disable HSR preload on the target

Answer

Increase the HSR timeout values significantly

Question 4

Refer to the exhibit. A migration engineer is setting up an IAM policy for an AWS DMS task that will replicate data from an on-premises SAP ASE database to Amazon RDS for SAP ASE. The engineer wants to ensure the DMS task can be created and started. What is missing from this policy?

Accepted Answer

Permissions to create DMS endpoints (dms:CreateEndpoint). The policy shown in the exhibit likely includes permissions for DMS actions like CreateReplicationTask and StartReplicationTask, but it omits the necessary permission to create the source and target endpoints. Without dms:CreateEndpoint, the engineer cannot define the connection information for the on-premises SAP ASE database and the RDS for SAP ASE instance, which are prerequisites for creating a replication task. Therefore, the missing permission is dms:CreateEndpoint.

Answer

Permissions to describe DMS replication instances

Answer

Permissions to start and stop replication tasks

Answer

Permissions to use AWS Key Management Service (KMS) for encryption

Question 5

Refer to the exhibit. A migration team is using AWS DMS to replicate data from an on-premises SAP ASE database to Amazon RDS for SAP ASE. The DMS task fails with the error shown. The source database is reachable from the DMS replication instance. What is the most likely cause?

Accepted Answer

The ODBC driver configuration on the DMS replication instance is incorrect. The error shown in the exhibit is a DMS connection failure that occurs after network reachability is confirmed, which points to a driver-level issue rather than connectivity. AWS DMS requires the correct ODBC driver to be installed and configured on the replication instance for the specific source engine (SAP ASE). If the ODBC driver is missing, misconfigured, or the wrong version, DMS cannot establish the database session even though the host and port are reachable.

Answer

The source database port is blocked by a firewall

Answer

The DMS task is using the wrong source engine type (e.g., SQL Server instead of SAP ASE)

Answer

The DMS replication instance does not have the required IAM permissions

Question 6

Refer to the exhibit. A company is migrating an SAP application server running on Windows to AWS. They launched an EC2 instance with Windows Server. After launching, they run the command and get the output shown. They need to install SAP software. What additional step is required before installing SAP?

Accepted Answer

Join the EC2 instance to an Active Directory domain. SAP application servers on Windows require the host to be joined to an Active Directory domain before SAP installation, because SAP uses AD for authentication, service account resolution, and domain-level security policies. The exhibit output (typically showing the instance is not domain-joined) signals this prerequisite is unmet. Joining the EC2 instance to the AD domain is therefore the required additional step before installing SAP.

Answer

Change the instance type to a memory-optimized instance

Answer

Stop and start the instance to initialize the Windows OS

Answer

Modify the security group to allow SAP-specific ports

Question 7

A company is migrating an on-premises SAP HANA database to AWS. The database is 2 TB in size. The migration window is limited to 3 days. Which AWS service should be used to perform the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge is a petabyte-scale data transport solution that physically moves large amounts of data into and out of AWS. For a 2 TB SAP HANA database migration with a 3-day window, Snowball Edge provides a secure, fast physical transfer that avoids the time and bandwidth constraints of network-based transfers. It is the recommended service for initial bulk data transfer when network transfer would exceed the migration window.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Direct Connect

Question 8

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?

Accepted Answer

Relaunch the deployment using a different Availability Zone in the same Region.. The error explicitly states the instance type is unavailable in the selected Availability Zone. Instance type availability varies by AZ within a Region, so the correct fix is to redeploy into an AZ where that instance type is offered. Launch Wizard lets you choose the AZ during deployment, so relaunching with a different AZ resolves the constraint without changing the instance type or the account limits.

Answer

Create a new VPC with different subnets and rerun Launch Wizard.

Answer

Modify the AWS CloudFormation template generated by Launch Wizard to specify a different instance type.

Answer

Request a limit increase for the instance type from AWS Support.

Question 9

An organization is migrating an SAP BusinessObjects system to AWS. The system uses a Sybase ASE database. They need to minimize downtime. Which migration strategy is most appropriate?

Accepted Answer

Use SAP Landscape Reorganization (LaMa) to automate the migration.. The best approach is to use SAP Landscape Reorganization (LaMa) which supports Sybase ASE and can automate the migration with minimal downtime. DMS does not support Sybase ASE as a source. HSR is for SAP HANA, not Sybase. Export/import is manual and leads to longer downtime.

Answer

Use AWS Database Migration Service (DMS) with ongoing replication.

Answer

Perform an export/import of the database to AWS.

Answer

Set up HANA System Replication (HSR) to the AWS target.

Question 10

A company is migrating an SAP system to AWS and wants to use an existing AWS Direct Connect connection for the migration. The on-premises network team reports that the Direct Connect link is consistently at 80% utilization during business hours. What should the company do to ensure a successful migration without impacting production traffic?

Accepted Answer

Schedule the migration during off-peak hours to avoid high utilization.. With the Direct Connect link already at 80% utilization during business hours, adding migration traffic risks saturating the link and degrading production. Scheduling the migration during off-peak hours uses the existing capacity when it is idle, avoiding impact to production traffic without requiring new infrastructure or procurement lead time. This is the pragmatic, lowest-risk answer given the constraint of 'without impacting production traffic.'

Answer

Increase the bandwidth of the Direct Connect link.

Answer

Use AWS Site-to-Site VPN over the internet as an alternative.

Answer

Use AWS Snowball Edge to transfer the data physically.

Question 11

A company is migrating an SAP HANA database to AWS. They have set up HANA System Replication (HSR) between the on-premises primary and an AWS secondary. The initial data synchronization is complete, but during the final cutover, the replication breaks due to network latency. What should the company do to complete the migration successfully?

Accepted Answer

Perform a manual takeover to promote the AWS secondary to primary.. When HSR replication breaks during cutover due to network latency, the AWS secondary already holds a fully synchronized copy of the data from the completed initial sync. A manual takeover (hdbnsutil -sr_takeover) promotes the secondary to primary, allowing the migration to complete without re-transferring data. This is the standard SAP HANA DR/cutover procedure when the primary is unreachable or replication is broken.

Answer

Set up a new HSR connection with a different port.

Answer

Increase the HSR timeout settings on the primary.

Answer

Restart the initial synchronization from scratch.

Question 12

During the migration of an SAP NetWeaver system, the team notices that the application server performance is degraded after migrating to AWS. The system uses AWS EBS volumes for storage. Which of the following is the most likely cause of the performance degradation?

Accepted Answer

The EBS volumes have insufficient provisioned IOPS for the workload.. If EBS volumes are not provisioned with sufficient IOPS, the application server may experience performance degradation. EBS-optimized instances and appropriate volume types are important. EBS volumes are typically designed for durability, and encryption does not cause performance degradation.

Answer

The EBS volumes are using the wrong volume type.

Answer

The EBS volumes are not encrypted.

Answer

The EBS volumes are not EBS-optimized.

Question 13

A company is migrating an SAP system to AWS using the SAP DMO (Database Migration Option) with system move. Which TWO prerequisites must be met before starting the migration?

Accepted Answer

The target EC2 instances and storage must be prepared in advance.. Option B is correct because SAP DMO with system move requires the target AWS environment to already exist: the target EC2 instances (with adequate CPU/memory for the SAP application and database) and the required EBS storage volumes must be provisioned and configured before the migration is started, since DMO writes the migrated database directly to the target system. Option C is correct because DMO is only supported for specific SAP NetWeaver releases and database combinations, so the source system must run a release that is on SAP's supported matrix for the DMO version being used; otherwise the migration cannot proceed. Option A is not required, as the target system can be deployed in an existing AWS account and no separate account is mandated. Option D is incorrect because the source database must be online and accessible during DMO, which performs the migration while the source system continues to run. Option E is not a strict prerequisite, since connectivity to AWS can be provided by other means (for example, internet-based access with appropriate security) and a VPN or Direct Connect is not mandatory for DMO with system move.

Answer

A separate AWS account must be used for the target system.

Answer

The source database must be stopped during the entire migration.

Answer

A VPN or Direct Connect connection must be established.

Question 14

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

Accepted Answer

The target EC2 instance must have at least the same amount of RAM as the source.. Option A is correct because SAP HANA sizing is memory-driven: the target EC2 instance must provide at least as much RAM as the source so the in-memory database and its row/column stores fit, and AWS instance types must be chosen accordingly (e.g., X1/X1e/X2/R4 for scale-up). Option C is correct because HSR requires the target to hold the full data volume plus redo logs, so the target storage (EBS volumes, e.g., gp2/gp3 or io1/io2) must be sized to accommodate the data volume with room for growth. Option D is correct because synchronous HSR requires low network latency (typically under 10 ms round-trip) between primary and secondary; otherwise replication mode must be switched to asynchronous, which affects RPO. Option B is not required: HSR can span AWS Regions (cross-Region replication) or even on-premises to AWS, so same-Region placement is not mandatory. Option E is not required: HSR replicates data regardless of encryption, and encryption at rest is an independent security choice, not a prerequisite for starting replication.

Answer

The source and target must be in the same AWS Region.

Answer

The source database must be encrypted before replication can start.

Question 15

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?

Accepted Answer

Migrate SAP systems from on-premises to AWS with minimal downtime.. 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.

Answer

Perform a heterogeneous system copy.

Answer

Convert the source database from Oracle to SAP HANA.

Answer

Automatically update DNS records after migration.
