PAS-C01 Migration Practice Test 15 — 15 Questions

Question 1

A company is migrating its SAP Business Warehouse (BW) on SAP HANA from on-premises to AWS. The source database is 6 TB, and the cutover window is limited to 4 hours. The team wants to minimize downtime and ensure data consistency. They plan to use SAP HANA system replication to a target Amazon EC2 instance on AWS. Which additional step is required before the final cutover to ensure that no data is lost during the replication?

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

Accepted Answer

Quiesce the source SAP HANA database and wait for the replication backlog to reach zero before cutover.. To guarantee no data loss during a cutover with SAP HANA system replication, the source must be quiesced so that all pending changes are replicated to the secondary. Once the replication backlog is zero, the secondary is fully synchronized and can take over. This approach is standard for near-zero-downtime migrations and meets the 4-hour window.

Answer

Configure SAP HANA multitenant database containers on the target to isolate the tenant.

Answer

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

Answer

Enable asynchronous replication and perform a final delta copy before switching over.

Question 2

A company is migrating its SAP S/4HANA system to AWS. The system uses SAP HANA database with high availability configured using SAP HANA System Replication. The company wants to ensure that the SAP HANA system replication traffic does not interfere with the application traffic and meets SAP's support requirements. Which AWS configuration should they use?

Accepted Answer

Place the SAP HANA instances in different subnets and use a separate security group for replication traffic, allowing only the necessary ports between the instances.. SAP recommends separating SAP HANA system replication traffic from application traffic to avoid performance impacts and to comply with support requirements. Using different subnets and a dedicated security group for replication traffic achieves this isolation. The security group can allow only the required ports (e.g., 50000-50014) between the primary and secondary instances, enhancing security and ensuring that replication traffic does not compete with application traffic.

Answer

Use AWS Transit Gateway to route replication traffic through a central hub, and apply network ACLs to filter traffic.

Answer

Place the SAP HANA primary and secondary instances in the same subnet and use the same security group for both application and replication traffic.

Answer

Enable enhanced networking with Elastic Network Adapter (ENA) on the instances and use a single subnet for both application and replication traffic.

Question 3

A company is migrating its SAP NetWeaver ABAP stack to AWS. The SAP system uses a central services instance (ASCS) and multiple application servers. The company wants to minimize the migration effort and avoid changing the SAP system configuration. Which migration method should be used?

Accepted Answer

Use AWS Application Migration Service (AWS MGN) to replicate the on-premises servers to AWS and launch them as EC2 instances.. AWS Application Migration Service (AWS MGN) is the ideal choice for lift-and-shift migrations of SAP NetWeaver ABAP stacks. It replicates the entire server, preserving the SAP configuration and minimizing effort. Other methods like system copy, HANA system replication, or DMS are not suitable because they either require reconfiguration, only handle databases, or do not cover the full SAP stack.

Answer

Perform a homogeneous system copy using SAP Software Provisioning Manager (SWPM) with a distributed system configuration.

Answer

Use SAP HANA system replication to replicate the SAP NetWeaver ABAP stack to AWS.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the SAP NetWeaver ABAP stack to AWS.

Question 4

A company is migrating a mission-critical SAP S/4HANA system to AWS. The system uses an Oracle database on-premises and will be migrated to SAP HANA on AWS. The migration must be completed with minimal downtime, and the company wants to use SAP-approved tools. The team plans to use the SAP Database Migration Option (DMO) with SUM. Which additional AWS service should be used to reduce the cutover downtime by replicating the source database to AWS before the final migration?

Accepted Answer

AWS Database Migration Service (AWS DMS) with change data capture (CDC).. AWS DMS with change data capture continuously replicates changes from the source Oracle database to the target SAP HANA database on AWS, keeping the target nearly synchronized. This reduces the amount of data that SUM/DMO must process during the final cutover, thereby minimizing downtime. It is a common pattern for large SAP migrations to AWS.

Answer

AWS Snowball Edge to ship the database backup to AWS.

Answer

AWS Storage Gateway in cached volume mode to replicate the database.

Answer

AWS DataSync to transfer the database files to Amazon S3.

Question 5

A company is migrating an SAP NetWeaver ABAP-based system from on-premises to AWS. The source system runs on an AIX-based IBM Power architecture. The migration team wants to use the SAP Database Migration Option (DMO) with SUM to combine the database migration and the SAP software update in a single step. Which prerequisite must be met before starting the DMO run?

Accepted Answer

The target database must be SAP HANA, and the source database must be one of the databases supported by DMO (e.g., Oracle, SQL Server, DB2, or SAP ASE).. SAP Database Migration Option (DMO) is a tool within SUM that allows a combined database migration and SAP software update in one step. It requires that the source database be one of the supported databases (Oracle, SQL Server, DB2, SAP ASE) and that the target be SAP HANA. The source system architecture, such as AIX on IBM Power, does not prevent DMO use as long as the database is supported and the target is HANA.

Answer

The SAP kernel must be at the latest patch level, and the source system must be on an SAP-supported operating system such as SUSE Linux Enterprise Server or Red Hat Enterprise Linux.

Answer

The source database must be SAP HANA, and the target database must be a non-HANA database supported by DMO.

Answer

The source system must already be running on an SAP-certified cloud instance type in AWS.

Question 6

A company is migrating a large SAP Business Suite system running on SAP HANA to AWS. They need to minimize downtime during the migration. Which two steps should they take to achieve this? (Choose two.)

Accepted Answer

Use SAP HANA System Replication (HSR) to replicate the database to an Amazon EC2 instance in AWS, then perform a takeover.. Using SAP HANA System Replication (HSR) to replicate the database to AWS and then performing a takeover minimizes downtime because HSR continuously replicates data and allows for a quick switchover. Similarly, a hybrid scenario with application servers on-premises and the database on AWS using HSR also minimizes downtime by replicating the database continuously and enabling a controlled cutover. Both approaches leverage HSR, which is the SAP-recommended method for near-zero downtime migrations.

Answer

Use AWS Application Migration Service (AWS MGN) to replicate the entire SAP system including the HANA database.

Answer

Use SAP Software Provisioning Manager (SWPM) to perform a homogeneous system copy with backup/restore.

Answer

Use AWS Database Migration Service (AWS DMS) with change data capture (CDC) to replicate the SAP HANA database.

Question 7

A company is planning to migrate a large SAP Business Warehouse (BW) system running on SAP HANA to AWS. The system uses a scale-out architecture with multiple HANA nodes. The company wants to minimize downtime during the migration and ensure data consistency. Which TWO steps should be performed as part of the migration plan? (Choose two.)

Accepted Answer

Use SAP HANA system replication with delta data shipping and take over after final synchronization.. The correct steps are to use SAP HANA system replication, either with continuous replication and takeover or with delta data shipping, to minimize downtime and ensure data consistency. These methods keep the AWS system synchronized with the on-premises system, allowing for a quick cutover. Other options either involve unsupported tools or require excessive downtime, making them unsuitable for a large scale-out SAP BW on HANA migration.

Answer

Perform a backup and restore using SAP HANA Studio, then apply delta merges.

Answer

Use AWS Database Migration Service (AWS DMS) with SAP HANA as a source and target.

Answer

Export the HANA database to a flat file using SAP HANA export, then import to AWS.

Question 8

A company is migrating a large SAP HANA database to AWS. The on-premises database is 10 TB, and the company wants to minimize downtime. They have a 1 Gbps AWS Direct Connect connection. Which method should be used to transfer the initial data set to AWS?

Accepted Answer

Use SAP HANA system replication over the Direct Connect connection to replicate the data to AWS.. SAP HANA system replication over AWS Direct Connect is the best method for migrating a 10 TB HANA database with minimal downtime. It allows online replication, and with 1 Gbps bandwidth, the initial sync can complete without taking the source offline. Other methods either require downtime, involve physical shipping, or use unsupported services like AWS DMS for HANA.

Answer

Use AWS Snowball Edge to transfer the data to Amazon S3, then restore it to Amazon EBS.

Answer

Take an offline backup, transfer it to AWS using AWS Snowball, and restore it to Amazon EBS.

Answer

Use AWS Database Migration Service (AWS DMS) to migrate the SAP HANA database to Amazon RDS for SAP HANA.

Question 9

A company is migrating a large SAP HANA scale-out system to AWS. The on-premises system uses a shared file system for the HANA data and log volumes, hosted on a NetApp storage system. The migration team plans to use AWS Launch Wizard for SAP to deploy the new environment. Which storage configuration should be used for the HANA data and log volumes on AWS to meet SAP performance requirements?

Accepted Answer

Amazon EBS gp3 volumes with additional IOPS and throughput provisioned, attached to each EC2 instance in the scale-out cluster.. SAP HANA on AWS requires storage that delivers low latency and high IOPS/throughput. Amazon EBS gp3 volumes with provisioned IOPS and throughput are the recommended choice for HANA data and log volumes. In a scale-out system, each node uses its own EBS volumes, and the file system is not shared across nodes for these volumes. This configuration is SAP-certified and meets the performance KPIs for HANA.

Answer

Amazon FSx for NetApp ONTAP with Multi-AZ deployment for both data and log volumes.

Answer

Amazon S3 mounted as a file system using AWS Storage Gateway in cached mode.

Answer

Instance store NVMe SSDs with RAID 0 for both data and log volumes.

Question 10

A company is migrating an SAP NetWeaver Java-based system to AWS. They need to ensure that the target system has the same SAP SID and hostname as the source. After the migration, they must update the SAP system to reflect the new AWS environment. Which step is necessary to achieve this?

Accepted Answer

Use the SAP system rename procedure to change the SAP SID and hostname, which includes updating the database and SAP profiles.. The SAP system rename procedure is the correct method to change the SAP SID and hostname of an existing SAP system. It ensures that all components, including the database and application servers, are updated consistently. This procedure is necessary when the target system must have the same SID and hostname as the source, and it is supported by SAP for both ABAP and Java stacks.

Answer

Run the SAPinst tool with the option to change the SAP SID and hostname.

Answer

Use the AWS Management Console to modify the instance metadata and change the hostname and SAP SID.

Answer

Run the SAP HANA database rename command to update the SID, and manually update the hostname in the SAP profiles.

Question 11

A company is migrating a SAP NetWeaver Java stack to AWS. The system uses an Oracle database on Amazon RDS for Oracle. The migration team needs to ensure that the SAP application can connect to the database securely and with high availability. They plan to use a Multi-AZ deployment for Amazon RDS. Which two configurations are required to meet these requirements? (Choose two.)

Accepted Answer

Configure the SAP application to connect to the RDS instance using the primary endpoint, which automatically fails over to the standby in case of an outage.. For high availability and security, the SAP application should connect to the RDS primary endpoint, which handles failover automatically. Credentials should be managed securely via AWS Secrets Manager to avoid hardcoding. These two configurations ensure that the application can reconnect after a failover and that database access is protected.

Answer

Use an Application Load Balancer to distribute connections between the primary and standby RDS instances.

Answer

Enable Multi-AZ on the RDS instance and configure the SAP application to connect to the standby instance directly for read operations.

Answer

Configure the RDS instance to use a public IP address so that the SAP application can connect from outside the VPC.

Question 12

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA database and has a large number of custom ABAP programs. The company wants to minimize the migration effort for the custom code. Which approach should they take?

Accepted Answer

Use the SAP Readiness Check for SAP S/4HANA to identify custom code that needs adaptation.. SAP Readiness Check for SAP S/4HANA is the correct tool because it analyzes the existing system and identifies custom code that is not compatible with S/4HANA. This allows the company to plan and execute the necessary adaptations efficiently. Other tools either focus on different aspects of the migration or do not provide the specific custom code analysis needed for S/4HANA.

Answer

Use the SAP HANA Application Lifecycle Management (HALM) to manage custom code.

Answer

Perform a database migration to SAP HANA using the DMO procedure of SUM.

Answer

Use the SAP Code Inspector to scan custom code for syntax errors.

Question 13

A company is migrating an SAP ERP system to AWS and plans to use Amazon EC2 instances for the application servers and Amazon RDS for SAP HANA for the database. They need to ensure that the SAP application servers can communicate with the database with minimal latency and high availability. Which configuration should they implement?

Accepted Answer

Place the EC2 instances and the RDS for SAP HANA instance in the same AWS Region and the same Availability Zone, and ensure they are in the same VPC and subnet.. Placing the EC2 instances and the RDS for SAP HANA instance in the same Availability Zone, VPC, and subnet minimizes latency by ensuring that network traffic does not traverse additional network devices or cross Availability Zone boundaries. This configuration is recommended for SAP systems to achieve low latency between application servers and the database, while still allowing for high availability through RDS Multi-AZ deployments.

Answer

Place the EC2 instances and the RDS for SAP HANA instance in the same AWS Region but in different VPCs, and use VPC peering to connect them.

Answer

Place the EC2 instances and the RDS for SAP HANA instance in the same AWS Region and the same Availability Zone, and use a cluster placement group for the EC2 instances.

Answer

Place the EC2 instances and the RDS for SAP HANA instance in the same AWS Region but in different Availability Zones.

Question 14

A company is migrating its SAP ERP Central Component (ECC) system to AWS. The system uses an Oracle database and runs on SUSE Linux Enterprise Server. The migration team wants to minimize downtime and ensure data consistency during the cutover. They plan to use a combination of SAP tools and AWS services. Which approach should be used to achieve near-zero downtime for the database migration?

Accepted Answer

Use Oracle Data Guard to replicate the on-premises Oracle database to an Amazon RDS for Oracle instance, then perform a switchover during cutover.. Oracle Data Guard is the optimal solution for near-zero downtime migration of an Oracle database to AWS. It replicates data continuously to a standby database on Amazon RDS for Oracle, and a switchover during cutover minimizes downtime to seconds or minutes. This ensures data consistency and meets the requirement for minimal downtime, unlike other methods that may require longer outages.

Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication to migrate the Oracle database to Amazon RDS for Oracle.

Answer

Use SAP Database Migration Option (DMO) with SUM to migrate directly from Oracle to SAP HANA in a single step.

Answer

Use SAP homogeneous system copy with backup and restore to an Amazon EC2 instance running Oracle, then apply redo logs.

Question 15

A company is migrating an SAP ERP system to AWS. The system uses an Oracle database on-premises and will be migrated to Amazon RDS for Oracle. The company requires that the database password for the master user be rotated every 90 days. Which solution meets this requirement with the LEAST operational overhead?

Accepted Answer

Use AWS Secrets Manager with automatic rotation enabled for the RDS database.. AWS Secrets Manager provides native support for rotating RDS database credentials. It can be configured to rotate the master password every 90 days automatically, eliminating manual effort. This is the most operationally efficient solution. Custom Lambda, Parameter Store, or RDS console options either require custom development or do not offer automatic rotation.

Answer

Create a custom AWS Lambda function that generates a new password and updates the RDS instance using the AWS SDK.

Answer

Use AWS Systems Manager Parameter Store with a rotation schedule managed by Amazon EventBridge.

Answer

Enable automatic password rotation in the RDS console for the master user.
