PAS-C01 Migration Practice Test 16 — 15 Questions

Question 1

A company is migrating an SAP ERP Central Component (ECC) system running on IBM Db2 to AWS. The database is approximately 2 TB, and the company wants to minimize downtime during the migration. The cutover window is limited to 4 hours. The company has a 1 Gbps dedicated network connection between on-premises and AWS. Which migration approach should be used to meet the downtime requirement?

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

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with change data capture (CDC) to replicate ongoing changes, then cut over during the window.. AWS DMS with change data capture enables continuous replication of changes from the source Db2 database to the target on AWS. The initial full load can be performed while the source remains online, and only the ongoing changes need to be applied during the cutover. This minimizes downtime to the time required to stop applications, allow replication to catch up, and redirect connections, which can be completed within a 4-hour window.

Answer

Use AWS Snowball Edge to ship the database offline, then restore and apply logs.

Answer

Use SAP Software Provisioning Manager (SWPM) to perform a homogeneous system copy with parallel export/import.

Answer

Use native Db2 backup and restore to an Amazon EC2 instance, then apply transaction logs during cutover.

Question 2

A company is migrating an SAP NetWeaver ABAP system to AWS. The system uses an SAP MaxDB database on-premises. The company wants to migrate to a managed database service on AWS. Which AWS service should they use?

Accepted Answer

Amazon RDS for Oracle. Amazon RDS for Oracle is the correct choice because it is a managed service certified for SAP NetWeaver. Since SAP MaxDB is not available as a managed service on AWS, the company must migrate to a supported database engine. Oracle is a common and well-supported option for SAP NetWeaver on RDS. Other options either do not exist as managed services or are not certified for SAP NetWeaver.

Answer

Amazon RDS for SAP MaxDB

Answer

Amazon RDS for PostgreSQL

Answer

Amazon RDS for SQL Server

Question 3

A company is migrating an SAP NetWeaver ABAP+Java (dual-stack) system from on-premises to AWS. The migration team must decide which AWS Snow Family device to use for the initial offline data transfer of the 90 TB source database, given that the on-premises site has only a 100 Mbps internet connection. Which AWS service should the team use to transfer the data?

Accepted Answer

AWS Snowball Edge Storage Optimized. AWS Snowball Edge Storage Optimized is the correct choice because it physically moves large volumes of data when network bandwidth is insufficient. The 100 Mbps connection would take over 80 days to transfer 90 TB, making online methods impractical. Snowball Edge provides 80 TB usable capacity per device, so a cluster or multiple devices can handle the dataset efficiently.

Answer

AWS DataSync

Answer

AWS Storage Gateway File Gateway

Answer

AWS Transfer Family

Question 4

A company is migrating an SAP S/4HANA system to AWS. The system uses SAP HANA 2.0 SPS05 and runs on an on-premises scale-up server. The target architecture will use Amazon EC2 X1e instances with multiple Elastic Block Store (EBS) volumes for data and log. The migration team wants to use SAP HANA system replication (HSR) for the initial data transfer to minimize downtime. Which configuration must be set up on the target EC2 instance to support HSR?

Accepted Answer

Configure the target instance with the same SAP HANA SID and instance number as the source, and enable the HSR secondary role.. SAP HANA system replication requires the secondary system to have the same SID and instance number as the primary. The secondary is configured with the HSR secondary role, and the primary is configured to replicate to the secondary. This setup enables continuous replication and allows for a takeover with minimal downtime during migration.

Answer

Enable Amazon EBS Multi-Attach on the data volumes to allow simultaneous access from both source and target.

Answer

Set up an AWS Direct Connect connection with a dedicated VLAN for HSR traffic.

Answer

Install the SAP HANA client on the target instance and configure the primary to use it as a remote data source.

Question 5

A company is migrating an SAP HANA database to AWS. The database is 2 TB and the company wants to minimize downtime. They plan to use SAP HANA System Replication (HSR) for the migration. Which TWO prerequisites must be met to use HSR for the migration? (Choose two.)

Accepted Answer

The network latency between the source and target systems must be low enough to support synchronous replication if using synchronous mode.. SAP HANA System Replication requires identical SAP HANA versions and patch levels for compatibility, and sufficient network performance for the chosen replication mode. Synchronous replication demands low latency. These are key prerequisites for a successful HSR-based migration to AWS. Other factors like SID, OS, or source hardware certification are not strict requirements for HSR itself.

Answer

The source SAP HANA system must be running on an SAP-certified hardware platform.

Answer

The target SAP HANA system must use the same operating system as the source.

Answer

The target SAP HANA system must be configured with the same SAP HANA system ID (SID) as the source.

Question 6

A company is migrating an SAP ERP Central Component (ECC) system running on IBM Db2 to AWS. The database is approximately 2 TB, and the company wants to minimize downtime during the migration. The cutover window is limited to 4 hours. The company has a 1 Gbps dedicated network connection between on-premises and AWS. Which migration approach should be used to meet the downtime requirement?

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

Accepted Answer

Use SAP HANA system replication to replicate data to an EC2 instance, then perform a takeover and SWPM to finalize the migration.. SAP HANA system replication is the correct method because it allows continuous data synchronization from on-premises to AWS with minimal downtime. The target system is kept up-to-date, and only a brief outage is needed for the final takeover and SWPM steps. This is a standard SAP-recommended approach for large HANA migrations to AWS.

Answer

Back up the source database to Amazon S3 using AWS Backup, then restore it to Amazon EC2.

Answer

Perform a standard export/import using SAP SWPM with the source system online.

Answer

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

Question 7

A company is migrating its SAP HANA database from on-premises to AWS. The database is 4 TB and must be migrated with minimal downtime. The company has a 10 Gbps AWS Direct Connect connection. They plan to use SAP HANA system replication to keep the source and target in sync. Which additional AWS service or feature should be used to ensure the target SAP HANA database on AWS has the same performance characteristics as the source during the migration?

Accepted Answer

Amazon EBS io2 Block Express volumes. Amazon EBS io2 Block Express volumes are certified by SAP for SAP HANA and provide the high IOPS and low latency required for production HANA databases. They support large volume sizes and can deliver consistent performance, making them ideal for a 4 TB HANA database migration. Using io2 Block Express ensures that the target database on AWS can handle the same workload as the on-premises source.

Answer

Amazon S3 with Transfer Acceleration

Answer

Amazon FSx for Lustre

Answer

Amazon EBS gp3 volumes with provisioned IOPS

Question 8

A company is migrating a legacy SAP ECC system to AWS. The system uses a MaxDB database. The company wants to use the classical migration approach: heterogeneous migration with SAP Software Provisioning Manager (SWPM). The project requires minimal downtime. Which method should the team use to export the MaxDB database to reduce downtime?

Accepted Answer

Use the SAP Migration Monitor with parallel export/import processes and delta replication.. For a classical heterogeneous migration with minimal downtime, the SAP Migration Monitor (part of SWPM) enables parallel export and import processes, which significantly speeds up the data transfer. It can also handle delta replication if the source database supports it, allowing most data to be migrated while the system remains online. This reduces the cutover window. DMO is specific to HANA targets and may not support MaxDB as a source. Simple export/import without parallelism leads to longer downtime, and HANA System Replication is not applicable to MaxDB.

Answer

Use the SAP HANA database migration option (DMO) of SUM to combine export and import.

Answer

Perform a database export using MaxDB tools, then import into the target database with SWPM during cutover.

Answer

Use SAP HANA System Replication to continuously replicate data to the target database.

Question 9

A company is migrating an SAP NetWeaver ABAP system from on-premises to AWS. The source system uses a non-Unicode kernel and the database is SAP MaxDB. The project team wants to use SAP Software Provisioning Manager (SWPM) to perform a homogeneous system copy to an EC2 instance running SUSE Linux Enterprise Server for SAP Applications. What must be done first to ensure the target system is supported on AWS?

Accepted Answer

Verify that the target OS and database combination is listed in the SAP Note for AWS supported platforms, and apply any required SAP kernel patches for the target release.. A homogeneous system copy with SWPM requires that the target OS and database are supported by SAP on AWS. Checking the relevant SAP Note and ensuring the kernel is patched correctly avoids an unsupported configuration. The other options either change the migration type unnecessarily or use an unsupported method.

Answer

Create an AMI of the on-premises server and launch it directly on AWS to avoid reinstallation.

Answer

Convert the non-Unicode system to Unicode and migrate the database to SAP HANA before the system copy.

Answer

Use the SAP HANA database instead of MaxDB because MaxDB is not supported on AWS EC2 instances.

Question 10

A company is migrating a large SAP NetWeaver system to AWS. The source system uses an Oracle database that will be migrated to Amazon RDS for Oracle. The migration window is 6 hours. The database is 2 TB, and the network bandwidth between on-premises and AWS is 500 Mbps. The team wants to use AWS Database Migration Service (AWS DMS) with change data capture (CDC) to minimize downtime. Which additional step is required to ensure a successful migration within the window?

Accepted Answer

Use AWS Snowball Edge to transfer the initial database backup to Amazon S3, then use AWS DMS with CDC.. The correct approach uses AWS Snowball Edge to physically transfer the large initial dataset, avoiding the slow network. Then AWS DMS with CDC handles ongoing changes, allowing a short cutover. This hybrid method minimizes downtime and fits the migration window. Simply relying on AWS DMS over the network would exceed the window due to bandwidth constraints.

Answer

Pre-create the target RDS for Oracle database with the same schema and use AWS DMS with ongoing replication.

Answer

Increase the network bandwidth to 1 Gbps and use AWS DMS with full load and CDC.

Answer

Use AWS DMS with a smaller replication instance and enable multi-threading to speed up the full load.

Question 11

A company is migrating a distributed SAP NetWeaver system (ABAP+Java) from on-premises to AWS. The system uses an Oracle database and will be migrated to SAP HANA on Amazon EC2. The migration team plans to use the classical migration approach with export/import (not DMO). They need to ensure that the target SAP system is properly prepared for the new database platform. Which TWO steps must be performed before starting the export/import migration? (Choose two.)

Accepted Answer

Perform a database-specific preparation, such as running SAP note 1912444 for Oracle to HANA migration, on the source system.. Before exporting from the source system in a classical migration, you must perform database-specific preparations such as applying SAP Note 1912444 for Oracle to HANA, and run migration checks using the SAP Migration Cockpit or ATC to identify and fix incompatibilities. These steps ensure the data and code are compatible with HANA, reducing the risk of errors during import and post-migration.

Answer

Set up SAP HANA system replication from the source Oracle database to the target HANA database.

Answer

Install the target SAP system with the same SAP SID and instance numbers as the source, using the SAPinst tool with the target database option.

Answer

Run the SAP Kernel Upgrade on the source system to a version that supports the target database.

Question 12

A company is migrating an SAP NetWeaver application server to AWS. The application server currently runs on a physical server with 16 vCPUs and 128 GB RAM. The company wants to use an Amazon EC2 instance that is SAP-certified for NetWeaver. Which EC2 instance family should they choose?

Accepted Answer

M5. The M5 instance family is a general-purpose, SAP-certified option for SAP NetWeaver application servers. It offers a balanced ratio of CPU to memory, making it suitable for the described workload. While R5 and C5 are also certified, M5 is the most appropriate for a typical application server. X1e is designed for HANA and not ideal for NetWeaver.

Answer

X1e

Answer

C5

Answer

R5

Question 13

A company is migrating an SAP S/4HANA system to AWS. The on-premises system uses an Oracle database and the migration team wants to use the SAP Database Migration Option (DMO) with SUM to convert to SAP HANA on an EC2 instance. The source database is 8 TB and the network bandwidth between the data center and AWS is 500 Mbps. The migration window is limited to a weekend. Which approach should be used to meet the time constraint?

Accepted Answer

Use AWS Snowball Edge to ship the source database backup to AWS, restore it to an EC2 instance, and then run DMO with SUM.. For large data volumes over limited bandwidth, physical data transfer with AWS Snowball Edge is the fastest way to get the data into AWS. Once the backup is in Amazon S3, the DMO migration runs inside AWS, avoiding the WAN bottleneck and fitting within the weekend window. The other options rely on network transfer or incorrect replication technology.

Answer

Set up AWS Direct Connect with a 1 Gbps dedicated connection and run DMO over that link.

Answer

Use SAP HANA System Replication to replicate the source database to AWS and then perform the DMO conversion.

Answer

Perform the DMO migration directly over the network using the existing 500 Mbps connection.

Question 14

A company is planning a homogeneous system copy of an SAP NetWeaver ABAP stack from on-premises to AWS. The source system runs on IBM Db2 and the target will use the same database platform on Amazon EC2. The migration window is tight and they want to minimize downtime. Which method should they use to export the SAP data?

Accepted Answer

Use the SAP kernel's R3load-based export with a migration monitor to allow parallel export and import processes.. For a homogeneous system copy of an SAP NetWeaver system on Db2 with minimal downtime, the R3load-based export with migration monitor is the appropriate method. It allows parallel export and import, reducing the overall migration window. Other methods either increase downtime or are not applicable to the database platform.

Answer

Use SAP Software Provisioning Manager (SWPM) with the 'System Copy' option and run the export in parallel with the database backup.

Answer

Use SAP HANA System Replication to replicate the Db2 database to AWS, then perform a takeover.

Answer

Perform an offline database backup on the source, restore it on the target, and then run SAP post-copy activities.

Question 15

A company is migrating its production SAP S/4HANA system to AWS. The system runs on SAP HANA on IBM Power Systems on-premises, and the company wants to move to an x86-based architecture on AWS with minimal changes to the application. The company also wants to use a managed database service to reduce operational overhead. Which migration approach should the company use?

Accepted Answer

Perform a homogeneous migration by moving the SAP HANA database from IBM Power to x86 on Amazon EC2, and then use SAP HANA system replication to minimize downtime.. The correct approach is to perform a homogeneous migration of SAP HANA from IBM Power to x86 on Amazon EC2, using SAP HANA system replication to minimize downtime. SAP HANA supports such migrations when the source and target run the same SAP HANA version. AWS does not offer a managed SAP HANA service, so the database must run on EC2. Other options involve unsupported services or incorrect assumptions about AWS offerings.

Answer

Lift and shift the entire SAP S/4HANA system to Amazon EC2 instances with SAP HANA on x86, then convert the database to Amazon RDS for SAP HANA.

Answer

Rehost the SAP S/4HANA system to Amazon EC2 instances running IBM Power, and then use AWS Application Migration Service to convert the database to x86.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the SAP HANA database to Amazon Aurora PostgreSQL, then point the SAP application to Aurora.
