PAS-C01 Migration Practice Test 10 — 15 Questions

Question 1

A company is planning to migrate its SAP environment to AWS. They have multiple SAP systems that are interconnected. Which migration approach is recommended to minimize dependency issues?

Accepted Answer

Migrate systems in logical groups that have dependencies on each other. When migrating interconnected SAP systems, the recommended approach is to migrate them in logical groups based on dependencies. This ensures that dependent systems are moved together, minimizing issues with integrations, interfaces, and data consistency. Option A is incorrect because ignoring technical dependencies can lead to broken integrations. Option C is incorrect because migrating by size may break dependencies across systems. Option D is incorrect because a big bang migration of all systems simultaneously is highly risky and complex.

Answer

Migrate systems based on business process priority, ignoring technical dependencies

Answer

Migrate systems individually based on size, starting with the smallest

Answer

Migrate all systems at the same time in a big bang approach

Question 2

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 3

A company is migrating an SAP ERP system to AWS using an SAP-certified backup/restore method. After restoring the database to Amazon RDS for SAP ASE, the SAP application fails to start with an error 'database connection refused'. The security group allows inbound traffic from the application server. What is the most likely cause?

Accepted Answer

The SAP application is using the wrong database hostname or port. After restoring the database to Amazon RDS, the database endpoint (hostname and port) changes. The SAP application likely still uses the old connection parameters, leading to a 'connection refused' error. Option A is incorrect because, although a stopped RDS instance would also cause this error, after a restore the instance is automatically started and running; a stopped state is unlikely. Option B is incorrect because outbound traffic rules are not required for inbound connections; the inbound rule on the database security group is sufficient. Option D is incorrect because different VPCs would typically result in 'no route to host' or timeout errors, not 'connection refused'.

Answer

The RDS instance is in a 'stopped' state

Answer

The security group does not allow outbound traffic

Answer

The RDS instance is in a different VPC than the application server

Question 4

A company is migrating its SAP landscape to AWS. They need to choose a migration method for each system. Which TWO factors are most important to consider when selecting a migration method for SAP systems? (Choose TWO.)

Accepted Answer

Source and target platform (OS, DB). Options C and E are correct. The source and target platform (OS, DB) and SAP release/database version are critical because they determine the availability and compatibility of migration tools (e.g., SUM, DMO, SWPM). Option A (total cost) is a business consideration, not a technical factor for method selection. Option B (backup frequency) relates to operational planning, not method choice. Option D (number of SAP users) affects sizing but not the migration method itself.

Answer

Total cost of migration

Answer

Frequency of database backups

Answer

Number of SAP users

Question 5

A company is migrating an SAP HANA database from on-premises to AWS using SAP HANA System Replication (HSR). They have set up the replication but the target database is not in sync. Which THREE configuration items should the migration team verify? (Choose THREE.)

Accepted Answer

The hostname resolution between source and target. HSR requires proper hostname resolution between source and target; if the target cannot resolve the source hostname, replication fails. Option B is correct because HSR requires the same major HANA version and build number; mismatches can prevent synchronization. Option C is incorrect because the SAP HANA license is not required for replication; it is tied to each system individually. Option D is correct because network connectivity and firewall rules must allow traffic on the HSR port (typically 3<instance>01); blocked ports will stop replication. Option E is incorrect because storage type (SSD vs HDD) does not affect HSR synchronization; replication works independently of underlying storage.

Answer

The SAP HANA license is activated on the target

Answer

The storage type (SSD vs HDD) is identical

Question 6

A company is migrating its SAP environment to AWS using AWS Launch Wizard for SAP. Which TWO pieces of information does Launch Wizard require to deploy an SAP system? (Choose TWO.)

Accepted Answer

SAP product version (e.g., SAP S/4HANA 2020). AWS Launch Wizard for SAP requires the SAP product version (e.g., SAP S/4HANA 2020) to determine the appropriate deployment template. Option E is correct because the SAP system ID (SID) is required for system identification. Option B is incorrect because the number of SAP users is not a required input; it is used for sizing estimates but not mandatory for deployment. Option C is incorrect because on-premises IP addresses are not needed; Launch Wizard designs the network setup for AWS. Option D is incorrect because the AWS account ID is automatically retrieved from the AWS environment and does not need to be provided.

Answer

Number of SAP users

Answer

On-premises IP addresses

Answer

AWS account ID

Question 7

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). Creating endpoints is a prerequisite for running a DMS task, and the provided policy does not include 'dms:CreateEndpoint'. Option B is incorrect because the policy does not include 'dms:DescribeReplicationInstances', but that is not required to create or start the task; the issue is missing endpoint creation permissions. Option C is incorrect because the policy does include 'dms:StartReplicationTask', so starting the task is allowed once endpoints exist. Option D is incorrect because the policy does not reference KMS actions, and encryption via KMS would require additional permissions, but that is not the immediate missing piece for creating and starting the task.

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 8

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 indicates an ODBC connection failure, which typically occurs when the ODBC driver or its configuration on the DMS replication instance is incorrect. Since the source database is reachable, the issue is not firewall or IAM permissions. The DMS task is using the correct source engine type (SAP ASE), so the most likely cause is a misconfigured ODBC driver on the replication instance, making Option A correct.

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 9

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 on Windows requires an Active Directory (AD) domain for Kerberos-based authentication, which is essential for SAP system communication. Before installing SAP software, the EC2 instance must be joined to an AD domain (e.g., via AWS Managed Microsoft AD or self-managed AD). Option A is incorrect because instance type selection should meet SAP requirements, but changing to memory-optimized is not a prerequisite for installation. Option B is incorrect: the instance is already running and stopping/starting does not initialize the OS beyond normal boot. Option C is incorrect: security group rules for SAP ports can be configured at any time before or after installation.

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 10

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 designed for large data transfers when network bandwidth is limited. The 2 TB database can be physically shipped and loaded onto AWS. AWS Direct Connect is for ongoing connectivity, not bulk transfer. AWS DataSync is for smaller datasets over the network. AWS DMS is for ongoing replication and requires network bandwidth.

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Answer

AWS Direct Connect

Question 11

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.. 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.

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 12

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 13

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.. The correct approach is to schedule the migration during off-peak hours when the link utilization is lower to avoid congestion. Increasing bandwidth may not be feasible immediately. Using VPN over the internet may add latency and security concerns. Snowball is for large data volumes, but if the data volume is manageable, off-peak migration is simpler.

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 14

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.. The correct action is to perform a manual failover using HSR takeover, which will promote the AWS secondary to primary and allow the system to continue. Increasing timeout may not resolve underlying latency. Restarting replication will take time. Setting up a new replication is unnecessary.

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 15

An organization is migrating an SAP ECC system to AWS using SAP Software Provisioning Manager (SWPM) and a homogeneous system copy. They have already exported the source system and are now importing to the target. The import fails with an error indicating that the target database tablespace is full. What should the administrator do to resolve the issue?

Accepted Answer

Increase the allocated storage for the target database tablespace.. The correct solution is to increase the size of the database tablespace on the target RDS instance or EC2-based database. Restarting the import without fixing the space issue will fail again. Reducing source export size is not appropriate as it would lose data. Using a different migration method is unnecessary.

Answer

Reduce the size of the source export by excluding some data.

Answer

Restart the import with a smaller package size.

Answer

Use SAP DMO instead of SWPM for the migration.
