PAS-C01 Migration Practice Test 31 — 15 Questions

Question 1

A company is migrating a large SAP HANA database (12 TB) to AWS using SAP HANA system replication. The source is on-premises, and the target is an Amazon EC2 instance. The network bandwidth between the sites is 1 Gbps, and the initial replication is expected to take several days. The company wants to minimize the impact on the production system during the initial replication. Which configuration should be used for the initial replication to reduce the load on the source system?

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

Accepted Answer

Perform a backup on the source, transfer it to AWS, and then start system replication.. Performing a backup and transferring it to AWS allows you to seed the target database without continuously reading from the production source. After the backup is restored on the target, system replication can be started to synchronize the delta changes, which is a much smaller load on the source. This approach is recommended for large databases over limited bandwidth.

Answer

Use asynchronous replication with a high log replay backlog.

Answer

Increase the network bandwidth to 10 Gbps to speed up the initial replication.

Answer

Use SAP HANA multitenant database containers to isolate the replication process.

Question 2

A company is migrating an SAP ERP Central Component system with an Oracle database to AWS. The database is 8 TB and the business requires a cutover window of no more than 6 hours. The team plans to use Oracle Data Guard in maximum performance mode to replicate to an Amazon RDS for Oracle target, then perform a switchover. The network link between on-premises and AWS supports 1 Gbps. Which consideration most affects whether the 6-hour cutover window can be met?

Accepted Answer

RDS for Oracle does not support Oracle Data Guard, so the replication design must be replaced with a physical standby on Amazon EC2 before cutover.. The decisive constraint is that Amazon RDS for Oracle does not allow the privileged configuration that Oracle Data Guard requires, so a Data Guard standby cannot be hosted on RDS. The team should run the Oracle standby on Amazon EC2, where SYSDBA control is available, or choose another replication approach. WAN replication and link capacity are manageable through seeding and maximum performance mode, and DB identity is not the fundamental blocker.

Answer

Oracle Data Guard maximum performance mode cannot be used across a WAN link and must be replaced with maximum availability mode.

Answer

Oracle Data Guard switchover requires the target database to use the same DB name and DBID as the source, which is not possible on RDS for Oracle.

Answer

A 1 Gbps link is insufficient to replicate an 8 TB database in the initial synchronization, so the cutover window cannot be met regardless of tooling.

Question 3

A company is migrating a SAP S/4HANA system to AWS. The system uses SAP HANA as the database. The migration team plans to use SAP HANA system replication to minimize downtime. They have set up the primary HANA instance on an Amazon EC2 instance in Availability Zone A and want to configure a secondary instance in Availability Zone B for high availability. Which network configuration is required to support SAP HANA system replication between the two Availability Zones?

Accepted Answer

Configure the instances in private subnets within the same VPC and allow traffic on the HANA system replication ports between the subnets.. SAP HANA system replication between Availability Zones requires network connectivity on specific ports. The instances should reside in private subnets within the same VPC, and security groups must allow the replication traffic. This configuration provides low latency and high availability without exposing the database to the internet.

Answer

Place both instances in the same subnet and use a placement group.

Answer

Use an AWS Direct Connect connection between the two Availability Zones.

Answer

Use a VPC peering connection between two VPCs in different regions.

Question 4

A company is migrating an SAP ERP Central Component (ECC) system to AWS. The system uses an Oracle database on-premises. The company wants to use a managed database service on AWS but needs to keep the Oracle database engine. Which AWS service should they use?

Accepted Answer

Amazon RDS for Oracle. Amazon RDS for Oracle is the correct service because it provides a managed Oracle database that is certified for SAP ECC. It allows the company to keep the Oracle engine while reducing administrative tasks. Other options either use different database engines or are not relational, so they do not meet the requirement to maintain Oracle.

Answer

Amazon RDS for SQL Server

Answer

Amazon DynamoDB

Answer

Amazon Aurora

Question 5

A company is migrating a large SAP NetWeaver system with an Oracle database to AWS. The database is 12 TB and must be migrated with minimal downtime. The company has a 1 Gbps AWS Direct Connect connection and wants to use a fully managed AWS service to replicate ongoing changes. Which AWS service should they use?

Accepted Answer

AWS Database Migration Service (AWS DMS). For minimal downtime database migration, AWS DMS is the appropriate service. It supports homogeneous migrations like Oracle to Amazon RDS for Oracle, performs an initial full load, and then replicates ongoing changes using change data capture. This allows the source database to remain operational until cutover, reducing downtime. Other services like DataSync, Snowball Edge, and Storage Gateway do not provide database replication with CDC.

Answer

AWS Storage Gateway

Answer

AWS DataSync

Answer

AWS Snowball Edge

Question 6

A company is migrating a performance-critical SAP NetWeaver ABAP system from on-premises to AWS. The system uses a scale-up architecture with a single application server and a single SAP HANA database. The company requires the highest possible network throughput and lowest latency between the application server and the database. Which AWS feature should be enabled to meet these requirements?

Accepted Answer

Cluster placement group. For performance-critical SAP NetWeaver systems with a scale-up architecture, the application server and database should be placed in a cluster placement group to ensure low-latency, high-throughput network connectivity. Cluster placement groups pack instances closely in a single Availability Zone, reducing network hops and increasing bandwidth. This aligns with AWS best practices for SAP workloads that require minimal latency between tiers.

Answer

Amazon EBS optimized instances

Answer

Elastic Fabric Adapter (EFA)

Answer

AWS Global Accelerator

Question 7

A company is migrating a 4 TB SAP Business Suite on Oracle database to SAP HANA on AWS. The cutover window is 6 hours. During a recent test, the export/import method took 14 hours. The team wants to use SAP Software Provisioning Manager (SWPM) with the DMO of SUM to combine migration and upgrade. Which TWO prerequisites must be validated before starting the DMO run? (Choose two.)

Accepted Answer

The SAP Host Agent must be installed on the source system and the target HANA host must be reachable on the required ports.. DMO combines the database migration and SAP upgrade in one run. Before starting, you must ensure the source SAP kernel and database patch level meet the minimum requirements for the SUM version, because SUM validates these at the beginning. Also, the SAP Host Agent must be present on the source and the target HANA host must be reachable on the necessary ports for remote execution and data transfer. Pre-creating the HANA tenant or converting the source DB is not part of the process.

Answer

The SAP system must be running on a distributed installation with a separate ASCS instance to support DMO.

Answer

The source database must be converted to SAP HANA before the DMO run to allow SUM to read HANA-specific metadata.

Answer

The target SAP HANA database must be installed and the tenant database must be pre-created before the DMO execution.

Question 8

A company is migrating an SAP NetWeaver ABAP-based system from on-premises to AWS. The source system runs on AIX with an Oracle database, and the target will use SAP HANA on Amazon EC2. The migration must be completed with minimal downtime and no changes to the SAP application layer. The team plans to use the SAP Database Migration Option (DMO) with SUM. Which additional step must be performed to ensure that the SAP kernel and application are compatible with the new database platform after the DMO run?

Accepted Answer

Run the SAP Kernel Upgrade and apply the latest kernel patch for the target database platform.. After using DMO to migrate from Oracle to SAP HANA, the SAP kernel must be updated to a version that supports the new database. The kernel contains database-specific libraries and interfaces; without the correct kernel, the SAP system will not start or will encounter errors. Other options are either unnecessary or address unrelated concerns.

Answer

Reinstall the SAP application server instances using the SAPinst tool with the same SID.

Answer

Convert all ABAP programs to run on the new database using the SAP Code Inspector.

Answer

Apply the SAP HANA-specific database hints to all custom ABAP reports.

Question 9

A company is migrating an SAP NetWeaver application server to AWS. The application uses a custom RFC destination to an external system. After the migration, the application cannot connect to the external system, although network connectivity tests succeed. The security team has restricted outbound traffic to specific ports. Which action should the SAP administrator take to resolve the issue?

Accepted Answer

Modify the security group associated with the SAP application server to allow outbound traffic on the port used by the RFC destination.. The security group attached to the SAP application server controls outbound traffic. Even if basic connectivity tests succeed, the specific port used by the RFC destination may be blocked. The administrator must add an outbound rule in the security group to permit traffic on that port to the external system. SAP profile parameters and ACL files do not control outbound network access, and changing the RFC type would not address the blocked port.

Answer

Update the SAP profile parameter rdisp/max_wprun_time to allow longer connection attempts.

Answer

Change the RFC destination in SM59 from type 3 to type H to use HTTP instead of RFC.

Answer

Add the external system's IP address to the SAP ACL file on the application server.

Question 10

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA as the database and runs on SUSE Linux Enterprise Server. The migration team wants to ensure that the SAP HANA database is highly available across two Availability Zones. Which two configurations should be used to achieve this? (Choose two.)

Accepted Answer

Deploy SAP HANA with synchronous replication to a secondary instance in a different Availability Zone using SAP HANA System Replication.. To achieve high availability for SAP HANA across two Availability Zones on AWS, you should use SAP HANA System Replication in synchronous mode to replicate data to a secondary instance in a different Availability Zone, and configure an overlay IP with a cluster manager like Pacemaker to manage failover and client connectivity. These two configurations together provide zero data loss and automated failover.

Answer

Use Amazon S3 Cross-Region Replication to replicate the HANA data and log backups to another region.

Answer

Use an Amazon Route 53 latency-based routing policy to distribute traffic between the two HANA instances.

Answer

Deploy both HANA instances in the same Availability Zone to reduce network latency.

Question 11

A company is planning to migrate an SAP NetWeaver system to AWS. They want to ensure that the migration is cost-effective and that the target environment meets SAP's performance requirements. Which AWS service should they use to validate the performance of the target environment before the migration?

Accepted Answer

AWS SAP-certified instances with SAP benchmarks. Using AWS SAP-certified instances with published SAP benchmarks ensures that the target environment meets SAP's performance requirements. AWS provides benchmark results for various SAP workloads, allowing companies to select the right instance types and validate performance before migration. This approach is cost-effective because it avoids over-provisioning and leverages AWS's validated configurations.

Answer

SAP Quick Sizer

Answer

AWS Database Migration Service (AWS DMS)

Answer

AWS Application Migration Service (AWS MGN)

Question 12

A company is migrating a large SAP Business Warehouse (BW) system to AWS. The source system runs on an Oracle database and uses SAP NetWeaver 7.5. The target will be SAP HANA on an Amazon EC2 X1e instance. The migration team wants to use SAP Database Migration Option (DMO) with SUM. During the pre-migration analysis, they discover that the source system has a high number of custom ABAP programs that use native SQL statements. What should the team do to ensure a successful migration?

Accepted Answer

Replace all native SQL statements with Open SQL or ABAP Database Connectivity (ADBC) before the DMO run.. Native SQL statements are database-dependent and often use syntax specific to the source database (Oracle). SAP HANA does not support all Oracle native SQL constructs, so these statements must be replaced with Open SQL or ADBC to ensure compatibility. This pre-migration remediation is critical for a successful DMO run and post-migration operation.

Answer

Use SAP HANA database hints to force the native SQL statements to execute on HANA.

Answer

Enable the SAP HANA compatibility mode for Oracle in the DMO configuration.

Answer

Configure the DMO to ignore native SQL statements and continue the migration.

Question 13

A company is planning to migrate an SAP Business Warehouse (BW) system to AWS. The system currently runs on an Oracle database on-premises. The migration team wants to use SAP Database Migration Option (DMO) to migrate to SAP HANA on AWS. Which AWS service should be used to host the target SAP HANA database?

Accepted Answer

Amazon EC2 instances with SAP HANA-certified instance types. SAP HANA on AWS is hosted on Amazon EC2 instances that are SAP-certified for HANA. These instances provide the necessary memory, CPU, and I/O performance. DMO migrates to SAP HANA, so the target must be an EC2-based HANA deployment. Amazon RDS, DynamoDB, and Aurora do not support SAP HANA and are not valid targets.

Answer

Amazon DynamoDB

Answer

Amazon Aurora

Answer

Amazon RDS for SAP HANA

Question 14

A company is migrating an SAP ERP Central Component (ECC) system to AWS. The system uses an Oracle database. The migration team plans to use AWS Application Migration Service (AWS MGN) to replicate the servers. After replication, they need to ensure that the SAP system starts correctly on AWS. Which post-migration task is required to adjust the SAP system to the new network environment?

Accepted Answer

Update the SAP profiles and the operating system hostname/IP mapping to reflect the new AWS network settings.. When migrating servers with AWS MGN, the SAP system's network identity changes. The SAP profiles (e.g., DEFAULT.PFL, instance profiles) contain hostname-specific parameters, and the operating system's hostname and hosts file must be updated. This ensures that SAP services bind to the correct network interfaces and can communicate internally and externally. Reinstallation or transport directory recreation is not required and would be disruptive.

Answer

Execute the SAP Note 962955 procedure to reset the SAP system's hostname and IP address.

Answer

Recreate the SAP transport directory and reimport all transport requests.

Answer

Run the SAPinst tool to reinstall the SAP system with the new hostname.

Question 15

A company is migrating an SAP S/4HANA system to AWS. The system uses a distributed deployment with a separate ASCS instance, a PAS, and an AAS. The database is SAP HANA. The migration team wants to use AWS Database Migration Service (AWS DMS) to replicate the HANA database to Amazon RDS for SAP HANA. Which statement accurately describes a limitation of using AWS DMS for this migration?

Accepted Answer

AWS DMS cannot replicate SAP HANA stored procedures, triggers, or other database-specific code, requiring manual migration of these objects.. AWS DMS is designed for data replication and does not migrate database code objects such as stored procedures, triggers, or calculation views. When migrating SAP HANA, these objects must be handled separately, often using SAP HANA export/import or SAP-specific tools. DMS supports HANA as a source and target, allows writes on the target, and can operate across Regions. The key limitation is the exclusion of procedural code, which requires manual intervention.

Answer

AWS DMS can only replicate data from HANA to HANA if both systems are in the same AWS Region.

Answer

AWS DMS requires the target HANA database to be in read-only mode during the entire replication process.

Answer

AWS DMS does not support SAP HANA as a source endpoint, so it cannot be used for this migration.
