PAS-C01 Migration Practice Test 33 — 15 Questions

Question 1

An SAP Basis team is migrating an SAP S/4HANA system to AWS using SAP HANA System Replication for the cutover. The source is on-premises and the target is an Amazon EC2 instance in a private subnet. The team wants to minimize the final cutover downtime and ensure the replication link survives the migration. Which combination of steps should they take before the final takeover?

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

Accepted Answer

Configure SAP HANA System Replication over a VPN or AWS Direct Connect, perform a full data initialization, then keep the secondary in sync and execute the takeover on the target during the change window.. SAP HANA System Replication over a VPN or AWS Direct Connect, followed by a full data initialization and continuous log shipping, is the standard way to migrate HANA to EC2 with minimal downtime. The secondary stays synchronized so the takeover applies only the remaining delta. Snapshot or file-copy approaches cannot provide the same low-downtime, consistent cutover.

Answer

Enable SAP HANA System Replication in asynchronous mode only, skip the initial data initialization, and let the target build its own data from redo logs at takeover.

Answer

Create an Amazon EBS snapshot of the on-premises SAP HANA volumes, register the snapshot as an AMI, and launch the target EC2 instance from that AMI during the change window.

Answer

Use AWS DataSync to copy the SAP HANA data and log volumes to Amazon EBS, then start SAP HANA on the target and point the application servers at the new host.

Question 2

A company is migrating a small SAP NetWeaver ABAP development system to AWS. The system is not business critical, and the team wants to minimize cost while keeping the migration simple. The database is SAP HANA and the application server runs on Linux. Which AWS service should the team use to host the SAP HANA database for this non-production system?

Accepted Answer

SAP HANA on an Amazon EC2 instance using a memory-optimized instance type. SAP HANA on AWS runs on Amazon EC2 with SAP-certified memory-optimized instance types; there is no managed RDS engine for HANA. For a non-production development system, selecting a smaller certified instance controls cost while keeping the deployment supported. DynamoDB and Aurora do not provide SAP HANA, and RDS for SAP HANA does not exist.

Answer

Amazon Aurora PostgreSQL with the SAP HANA compatibility extension enabled

Answer

Amazon DynamoDB with a compatibility layer for SAP HANA SQL

Answer

Amazon RDS for SAP HANA

Question 3

A company is migrating a large SAP NetWeaver system to AWS. The system includes an SAP HANA database and multiple SAP application servers. The company wants to minimize downtime and ensure data consistency during the migration. They plan to use SAP HANA system replication for the database and AWS Application Migration Service (AWS MGN) for the application servers. Which additional step is required to ensure that the application servers are consistent with the database at cutover?

Accepted Answer

Stop the SAP application servers on-premises before the final database takeover, and then start them on AWS after the database is available.. To ensure data consistency during a migration that uses SAP HANA system replication for the database and AWS MGN for application servers, the SAP application servers must be stopped before the final database takeover. This prevents any writes to the old database after the new one is promoted. After takeover, the application servers can be started on AWS and connected to the new database. Other options either propose unsupported tools or irrelevant features.

Answer

Enable SAP HANA multitenant database containers on the target system to isolate the application servers during the migration.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate ongoing changes from the on-premises SAP HANA database to Amazon EC2 after the initial system replication.

Answer

Configure AWS MGN to continuously replicate the application servers and then perform a final synchronization of the application servers with the database before cutover.

Question 4

A company is migrating a mission-critical SAP NetWeaver ABAP system to AWS. The system uses an Oracle Database 19c on-premises. The migration must minimize downtime, and the database must remain on Oracle for at least six months. The company wants to use AWS DMS to replicate data continuously from the on-premises Oracle database to an Amazon RDS for Oracle DB instance. After the cutover, the SAP application will point to the RDS instance. Which AWS DMS configuration is MOST appropriate for this migration?

Accepted Answer

Use AWS DMS with a replication instance in a private subnet, and configure the source endpoint with the on-premises Oracle database. Use ongoing replication (CDC) to capture changes.. For minimal downtime, AWS DMS with ongoing replication (CDC) is essential. The replication instance must be in a private subnet for security, and connectivity to on-premises should be through VPN or Direct Connect. This setup allows continuous synchronization until cutover, reducing downtime to a brief final switchover. Disabling validation or using full load only would compromise data integrity or increase downtime.

Answer

Use AWS DMS with a replication instance in a private subnet, and configure the source endpoint with the on-premises Oracle database. Use full load only, and perform a final delta copy manually before cutover.

Answer

Use AWS DMS with a replication instance in a public subnet, and configure the source endpoint with the on-premises Oracle database. Use ongoing replication (CDC) to capture changes.

Answer

Use AWS DMS with a replication instance in a private subnet, and configure the source endpoint with the on-premises Oracle database. Use ongoing replication (CDC) but disable validation to improve performance.

Question 5

A company is migrating an SAP S/4HANA system to AWS using a lift-and-shift approach with AWS Application Migration Service for the application servers and native SAP HANA backup/restore for the database. Before the cutover, the team must validate that the target environment can support the production workload. Which three validation activities should the SAP solution architect include in the cutover runbook? (Choose three.)

Accepted Answer

Verify that the target EC2 instances have the SAP-supported instance types and that the operating system, kernel, and SAP HANA revision match the supported combinations in the SAP Product Availability Matrix.. Cutover validation for a lift-and-shift SAP migration must cover three layers: SAP-level health and supportability, functional correctness, and support matrix compliance. Running EarlyWatch Alert against a baseline, executing regression tests with production-like data, and confirming instance type, OS, kernel, and HANA revision against the SAP Product Availability Matrix together give confidence that the target can carry production traffic. Logging must remain enabled to support troubleshooting.

Answer

Disable AWS CloudTrail and Amazon CloudWatch logging on the target accounts to eliminate logging overhead during the performance test.

Answer

Perform a full SAP HANA database consistency check with hdbcons and compare checksums with the source database to verify the restore.

Question 6

A company is migrating its SAP ERP Central Component (ECC) system to AWS. The system uses an Oracle database on AIX. The migration team decides to use a homogeneous migration approach by moving to Amazon EC2 with Oracle Linux and Oracle Database. They need to transfer the database while minimizing downtime. Which method should they use for the initial data transfer and ongoing synchronization?

Accepted Answer

Use Oracle Data Guard to replicate from on-premises to Amazon EC2. Oracle Data Guard is a native Oracle replication solution that maintains a standby database in sync with the primary. For a homogeneous migration to EC2, it allows the team to set up a standby in AWS, let it catch up, and then perform a fast switchover with minimal downtime. Other methods either lack ongoing synchronization, are not designed for homogeneous Oracle migrations, or involve offline transfer that cannot meet the downtime goal.

Answer

Use AWS Snowball Edge to ship the database files to AWS

Answer

Use Oracle Recovery Manager (RMAN) to take a full backup and restore it on EC2

Answer

Use AWS Database Migration Service (AWS DMS) with change data capture (CDC)

Question 7

A company is planning to migrate its SAP NetWeaver Application Server ABAP system to AWS. The system currently runs on physical servers on-premises. The company wants to reduce the migration time and effort by using AWS Application Migration Service (AWS MGN). Which statement is true regarding the use of AWS MGN for this SAP system?

Accepted Answer

AWS MGN can replicate the SAP system to AWS and automatically convert it to run on Amazon EC2 instances, supporting both Linux and Windows.. AWS Application Migration Service (AWS MGN) is designed to simplify and expedite server migrations to AWS by replicating source servers and automatically converting them to run on EC2. It supports both Linux and Windows, making it suitable for SAP NetWeaver ABAP systems. It does not require specific virtualization platforms and can handle physical servers, aligning with the company's on-premises setup.

Answer

AWS MGN only supports migration of databases, not application servers, so it cannot be used for SAP NetWeaver.

Answer

AWS MGN cannot be used for SAP systems because SAP does not support migrations to AWS using replication tools.

Answer

AWS MGN requires the source servers to be running on VMware vSphere or Microsoft Hyper-V.

Question 8

A company is migrating its SAP ERP system to AWS. The system uses an Oracle database and runs on AIX. The company wants to move to a Linux environment on AWS with SAP HANA as the database. They plan to use a big-bang cutover during a weekend. Which migration strategy should they use?

Accepted Answer

Re-platform by migrating to Linux on AWS and using SAP HANA, using SAP DMO to combine the OS/DB migration.. The re-platform strategy is appropriate because it involves migrating the SAP system to AWS while changing the operating system from AIX to Linux and the database from Oracle to SAP HANA. SAP DMO facilitates this by combining the OS/DB migration and SAP upgrade into a single process, reducing downtime and complexity. This aligns with the company's goal of a weekend cutover.

Answer

Refactor the SAP application to a microservices architecture on AWS.

Answer

Retain the SAP system on-premises and use AWS for backup and disaster recovery only.

Answer

Lift and shift the entire SAP system to AWS, keeping AIX and Oracle.

Question 9

A company is migrating its SAP S/4HANA system to AWS. The system uses SAP HANA 2.0 SPS05 and runs on a scale-up architecture. The company wants to use Amazon EC2 instances with SAP HANA certified hardware. They need to ensure that the instance type supports the required memory and that the storage configuration meets SAP's performance requirements for the HANA database. Which combination of EC2 instance family and storage type should they use?

Accepted Answer

Use an X1e instance with Amazon EBS io1 volumes with provisioned IOPS for data and log.. SAP HANA on AWS requires memory-optimized EC2 instances certified by SAP, such as X1e or High Memory instances. For storage, provisioned IOPS volumes like io1 or io2 are necessary to meet the low-latency, high-IOPS demands of HANA. Using general-purpose instances or throughput-optimized HDD volumes would not meet performance requirements and could violate SAP support agreements.

Answer

Use an X1e instance with Amazon EBS gp2 volumes for data and log.

Answer

Use an X1e instance with Amazon EBS st1 volumes for data and log.

Answer

Use an M5 instance with Amazon EBS io1 volumes with provisioned IOPS for data and log.

Question 10

A company is migrating a small SAP Business One system to AWS. The system uses Microsoft SQL Server as the database. The company wants to minimize the migration effort and use a managed database service. Which AWS service should they use for the database?

Accepted Answer

Amazon RDS for SQL Server. SAP Business One requires a relational database, and Microsoft SQL Server is a supported option. Amazon RDS for SQL Server provides a managed environment that reduces operational effort while meeting the application's requirements. The other services are either non‑relational or not designed for transactional workloads.

Answer

Amazon Redshift

Answer

Amazon ElastiCache for Redis

Answer

Amazon DynamoDB

Question 11

A company is migrating an SAP HANA database to AWS. The database is currently on-premises and uses SAP HANA System Replication for high availability. The company plans to use Amazon EC2 instances with Amazon EBS for storage. The migration must ensure that the SAP HANA system replication continues to work in AWS with minimal latency. Which storage configuration should be used for the SAP HANA data and log volumes to achieve this?

Accepted Answer

Use Amazon EBS io2 Block Express volumes for data and log, and configure them according to SAP HANA on AWS best practices.. SAP HANA requires high-performance, low-latency block storage. Amazon EBS io2 Block Express volumes deliver the necessary IOPS and sub-millisecond latency, and when configured per SAP HANA on AWS best practices, they ensure optimal performance for both data and log volumes. This configuration supports SAP HANA system replication with minimal latency.

Answer

Use Amazon EFS for data and log volumes to enable shared storage across multiple EC2 instances.

Answer

Use Amazon EBS io1 volumes for data and log, and place them in a RAID 0 configuration for increased performance.

Answer

Use Amazon EBS gp2 volumes for data and log, and enable EBS Multi-Attach for the log volume.

Question 12

A company is migrating a small SAP NetWeaver Java system to AWS. The system uses an Oracle database that will be migrated to Amazon RDS for Oracle. The database is 300 GB and the company can afford a maintenance window of several hours. The team wants the simplest, most reliable migration with minimal licensing complexity. Which approach should the team use?

Accepted Answer

Use Oracle Data Pump to export the schema from the on-premises database, transfer the dump file to Amazon S3, and import it into Amazon RDS for Oracle using the RDS-provided Data Pump utility.. Oracle Data Pump export and import through Amazon S3 is the simplest and most reliable way to move a small Oracle database into Amazon RDS for Oracle. The managed service supports Data Pump imports from S3, and with a several-hour window and no near-zero-downtime requirement, this logical method avoids the added complexity of replication tools and unsupported physical restore options.

Answer

Configure Oracle Active Data Guard between the on-premises database and Amazon RDS for Oracle, then perform a switchover during the maintenance window.

Answer

Use AWS Database Migration Service (AWS DMS) with a full-load and change-data-capture task to replicate the Oracle schema into Amazon RDS for Oracle.

Answer

Take a physical backup of the on-premises Oracle database, copy the backup pieces to Amazon S3, and restore them directly into Amazon RDS for Oracle.

Question 13

A company is migrating a mission-critical SAP S/4HANA system to AWS. The system uses SAP HANA with a large dataset. The migration must minimize downtime and ensure data consistency. The team plans to use AWS DataSync for the /hana/data and /hana/log volumes from on-premises NFS storage to Amazon EFS. Which statement about this plan is accurate?

Accepted Answer

AWS DataSync can copy the HANA data and log files to Amazon EFS, but HANA does not support running on EFS; the target must use Amazon EBS or FSx for Lustre.. SAP HANA requires block-level storage such as Amazon EBS or FSx for Lustre for data and log volumes. Amazon EFS is not supported for HANA, despite being a scalable file system. AWS DataSync can transfer files to EFS, but the target architecture would be invalid for HANA. The correct approach involves using DataSync to move data to a supported storage service or using a database-level migration method like HANA system replication or backup/restore.

Answer

AWS DataSync supports SAP HANA system replication, so it can be used to set up a standby HANA system on AWS with minimal downtime.

Answer

AWS DataSync can copy the HANA data and log files to Amazon EFS, and HANA can run on EFS if the EFS file system is provisioned with sufficient throughput.

Answer

AWS DataSync can copy the HANA data and log files directly to Amazon EBS volumes, and HANA will start without additional configuration.

Question 14

A company is migrating a legacy SAP ERP system to AWS. The system currently runs on an unsupported operating system and database. The company wants to move to a supported platform on AWS with minimal effort. They plan to use SAP's Software Update Manager (SUM) with the Database Migration Option (DMO). Which AWS service should they use to host the target SAP system during the migration?

Accepted Answer

Amazon EC2 instances with SAP HANA. The target SAP system during a DMO migration must run on Amazon EC2 with SAP HANA, as SAP HANA on AWS is only supported on EC2. Amazon RDS does not offer SAP HANA, and Aurora PostgreSQL and Redshift are not supported for SAP ERP. Therefore, Amazon EC2 instances with SAP HANA is the correct choice to host the target system.

Answer

Amazon Aurora PostgreSQL

Answer

Amazon Redshift

Answer

Amazon RDS for SAP HANA

Question 15

A company is migrating an SAP Business Warehouse system running on SAP HANA to AWS. The database is 4 TB and the company wants to minimize the amount of data transferred over its 200 Mbps internet connection during the migration. The company has no existing AWS Direct Connect connection and the migration window starts in two weeks. Which approach should the SAP solution architect recommend for the initial data transfer?

Accepted Answer

Order an AWS Snowball Edge Storage Optimized device, copy the SAP HANA database backup to it, ship it to AWS, and import the data into Amazon S3.. When a large dataset must move to AWS and the available internet bandwidth would make the transfer slow or disruptive, an AWS Snowball Edge device is the appropriate choice. The backup is written to the device on-premises, shipped to AWS, and imported into Amazon S3, after which the target SAP HANA system can restore from it. This avoids saturating the 200 Mbps link and fits the two-week timeline.

Answer

Use AWS Transfer Family with SFTP to upload the backup files to Amazon S3 from the on-premises system.

Answer

Use AWS Storage Gateway in cached mode to present the on-premises backup as an S3 bucket and let the target system read directly from the gateway.

Answer

Use AWS DataSync over the 200 Mbps internet connection to copy the backup to Amazon S3 before the migration window.
