Which combination of AWS services and tools should the team use to migrate the SAP application servers and the database?

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

Accepted Answer

AWS Application Migration Service (AWS MGN) for the application servers and AWS Database Migration Service (AWS DMS) for the database.. For a lift-and-shift migration of SAP application servers, AWS Application Migration Service (AWS MGN) is the current recommended tool that replicates servers at the block level and automates conversion to run on AWS. For the database, AWS DMS can perform a minimal-downtime migration if the database engine is supported. This combination minimizes changes to the SAP application and reduces cutover downtime.

Answer

AWS Server Migration Service (SMS) for the application servers and native database backup/restore for the database.

Answer

AWS DataSync for the application servers and AWS Snowball Edge for the database.

Answer

AWS CloudEndure Migration for the application servers and AWS DMS for the database.

Question 2

A company is migrating an SAP NetWeaver Java-based system to AWS. The system uses an Oracle database and runs on SUSE Linux Enterprise Server. The migration team plans to use a homogeneous system copy using SAP's software provisioning manager (SWPM). They need to ensure that the target system on AWS meets SAP's requirements. Which TWO actions must be performed before running the system copy? (Choose two.)

Accepted Answer

Ensure that the target EC2 instances have the same hostnames and SAP SIDs as the source system.. For a homogeneous system copy, the target must match the source in terms of SAP SID, hostnames, kernel release, and patch level, as well as the operating system and database platform. The two required actions are ensuring identical hostnames and SIDs, and installing the same kernel release and patch level. The other options would make the copy heterogeneous or are handled by SWPM.

Answer

Change the target instance's operating system to Red Hat Enterprise Linux.

Answer

Pre-create the Oracle database instance on the target with the same schema and tablespaces.

Answer

Convert the Oracle database to SAP HANA before the system copy.

Question 3

An SAP solution architect is planning the migration of an SAP NetWeaver ABAP system to AWS. The on-premises servers use hostnames that are embedded in SAP profiles, RFC destinations, and a large number of custom interfaces. The company wants to avoid changing hostnames and wants the migration to be reversible for 30 days in case of issues. The database is SAP HANA and will be migrated with SAP HANA system replication. Which combination of AWS services and features best supports this requirement?

Accepted Answer

Keep the source system running as the authoritative system, replicate the application servers with AWS Application Migration Service, and use SAP HANA system replication in a multi-target or primary/secondary configuration with a planned takeover; retain the source for rollback and use a temporary DNS or hosts-file mapping for the target during validation.. A reversible SAP migration that preserves hostnames requires keeping the source authoritative while replicating both the application and database tiers. AWS Application Migration Service replicates the application servers, SAP HANA system replication provides a consistent secondary database with a controlled takeover, and the original system remains available for rollback. Name resolution is handled on the target side with temporary mappings until the final cutover, when the original hostnames are assumed by the AWS instances after the source is decommissioned.

Answer

Deploy the target SAP system in a dedicated Amazon VPC with Amazon Route 53 private hosted zones that resolve the original hostnames to the EC2 instances, and use AWS Application Migration Service for the application servers.

Answer

Use AWS Application Migration Service to replicate the application servers, assign the original hostnames to the launched EC2 instances, and keep the source servers running as the authoritative system until cutover; use SAP HANA system replication with a takeover for the database.

Answer

Perform a homogeneous system copy with SAP SWPM, rename the target system to a new SID and hostname, and update all custom interfaces to use the new names.

Question 4

A company is migrating a large SAP Business Warehouse (BW) system on SAP HANA to AWS. The system is currently running on a scale-out HANA configuration with multiple worker nodes. The company wants to ensure that the migration to AWS maintains high availability and optimal performance. Which two actions should be taken during the migration? (Choose two.)

Accepted Answer

Configure Amazon EBS io2 Block Express volumes for the HANA data and log volumes.. For a scale-out SAP HANA system on AWS, using a cluster placement group ensures low-latency networking between nodes, which is essential for performance. Configuring Amazon EBS io2 Block Express volumes provides the necessary high IOPS and low latency for HANA data and log storage. These two actions help maintain optimal performance and high availability by leveraging AWS features certified for SAP HANA.

Answer

Use AWS Snowball Edge to transfer the HANA database to AWS.

Answer

Enable Multi-AZ deployment for the HANA database using synchronous replication.

Answer

Deploy the HANA scale-out nodes across multiple Availability Zones.

Question 5

A company is migrating a large SAP HANA database to AWS. The database is 4 TB and the business requires a downtime window of no more than 4 hours. The migration team plans to use SAP HANA system replication to an Amazon EC2 instance in AWS. Which additional AWS service or feature should they use to minimize the data transfer time during the initial synchronization?

Accepted Answer

AWS Direct Connect with a dedicated 10 Gbps connection. For SAP HANA system replication, a high-bandwidth, low-latency network connection is critical to complete the initial synchronization within the downtime window. AWS Direct Connect with a dedicated 10 Gbps connection offers the necessary throughput and consistency. Other options either use the public internet, are offline, or are not designed for database replication. Direct Connect ensures the 4 TB transfer can complete in time while maintaining data integrity.

Answer

AWS Snowball Edge

Answer

AWS Site-to-Site VPN

Answer

AWS DataSync

Question 6

A company is migrating a large SAP HANA database (10 TB) to AWS. The on-premises network bandwidth is limited to 1 Gbps, and the migration must be completed within two weeks. The company wants to minimize the impact on the production system and ensure data consistency. Which approach should they take to migrate the database?

Accepted Answer

Use AWS Snowball Edge to transfer the initial SAP HANA backup to AWS, then use SAP HANA system replication for delta changes.. The correct approach is to use AWS Snowball Edge for the initial full backup transfer, followed by SAP HANA system replication for delta changes. This leverages offline transfer for the bulk data, avoiding network congestion, and uses replication for ongoing synchronization. It ensures data consistency and minimizes downtime, making it suitable for a 10 TB database with limited bandwidth.

Answer

Use SAP HANA system replication to an Amazon EC2 instance over the network, then perform a takeover.

Answer

Use AWS Snowball Edge devices to transfer the SAP HANA database offline, then perform a delta sync with AWS Database Migration Service (AWS DMS).

Answer

Use AWS DataSync to transfer the SAP HANA data files to Amazon S3, then restore to Amazon EC2.

Question 7

A company is migrating a production SAP S/4HANA system to AWS. The system uses a distributed deployment with separate ASCS, PAS, and AAS instances, and SAP HANA runs on a dedicated EC2 instance. The migration team must ensure that the SAP system is highly available across two Availability Zones. Which configuration should the team implement for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS)?

Accepted Answer

Deploy ASCS on one EC2 instance in Availability Zone A and ERS on another EC2 instance in Availability Zone B, using an overlay IP address and a cluster solution such as SUSE Linux Enterprise High Availability Extension.. Deploying ASCS and ERS on separate EC2 instances in different Availability Zones with an overlay IP and a cluster solution like SUSE Linux Enterprise High Availability Extension is the correct approach. This configuration ensures that if the ASCS instance fails, the cluster can move the overlay IP and ASCS role to the ERS instance, providing automatic failover and high availability.

Answer

Use an Amazon EC2 Auto Scaling group with a launch template that spans two Availability Zones, and configure the ASCS and ERS on the same instance.

Answer

Place both ASCS and ERS on the same EC2 instance but in different subnets, and use Amazon Route 53 health checks to redirect traffic.

Answer

Use AWS Elastic Disaster Recovery to replicate the ASCS instance to another Availability Zone, and manually start the replica in case of failure.

Question 8

A company is migrating its SAP ERP Central Component (ECC) system to AWS. The system uses an Oracle database and runs on AIX. The migration strategy is to rehost to Amazon EC2 instances with Linux and migrate the database to Amazon RDS for Oracle. The company wants to minimize changes to the SAP application and ensure that the database migration is as seamless as possible. Which combination of steps should be taken to achieve this? (Choose two.)

Accepted Answer

Ensure the target Amazon RDS for Oracle instance is configured with the same Oracle version and patch level as the source database.. Using SAP SUM with DMO is the SAP-supported method for database migration while minimizing changes to the SAP application. Ensuring the target RDS for Oracle matches the source Oracle version and patch level avoids compatibility issues. Together, these steps provide a seamless migration path for the SAP ECC system from AIX/Oracle to Linux/RDS for Oracle.

Answer

Use AWS Database Migration Service (AWS DMS) to replicate the Oracle database to Amazon RDS for Oracle, and then switch over the SAP application.

Answer

Perform a homogeneous system copy using SAP tools, and then use Oracle Data Pump to migrate the database to Amazon RDS for Oracle.

Answer

Use SAP heterogeneous system copy with the SAP Migration Monitor to export and import the database to Amazon RDS for Oracle.

Question 9

A company is migrating an SAP S/4HANA system to AWS. The source system uses SAP HANA 2.0 SPS05 and the target will use Amazon EC2 with SAP HANA. The migration must be done with minimal downtime and the source system must remain operational during the initial data transfer. Which approach should they use?

Accepted Answer

Use SAP HANA System Replication (HSR) in delta mode to replicate data to the target, then perform a takeover.. SAP HANA System Replication in delta mode enables near-zero downtime migration by keeping the target synchronized with the source until a planned takeover. It is the recommended method for migrating SAP HANA to AWS while the source remains operational. Other options either lack continuous replication or are not supported for SAP HANA.

Answer

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

Answer

Use SAP HANA backup and recovery to restore a full backup on the target, then apply redo logs.

Answer

Use SAP HANA remote data sync to continuously replicate data to the target, then switch over.

Question 10

A company is migrating its SAP S/4HANA system to AWS. The system uses SAP HANA database with a high availability setup using SAP HANA System Replication. The company wants to ensure that the replication traffic does not interfere with the application traffic and that the replication is secure. They have deployed the primary and secondary HANA instances in separate AWS Availability Zones within the same AWS Region. Which configuration should they use for the SAP HANA System Replication network?

Accepted Answer

Place the primary and secondary instances in separate subnets and use a dedicated security group for replication traffic, enabling encryption in transit.. To separate replication traffic from application traffic and secure it, the best approach is to place the primary and secondary SAP HANA instances in separate subnets (which inherently separates network traffic) and use a dedicated security group that only allows replication traffic between them. Enabling encryption in transit for SAP HANA System Replication (using TLS) ensures the data is secure. This is a standard best practice for SAP HANA HA on AWS. The other options either do not isolate the traffic or introduce unnecessary services.

Answer

Use the same subnet for both primary and secondary instances and enable encryption at the application layer.

Answer

Configure a separate VPC peering connection between the two instances and use AWS PrivateLink for replication.

Answer

Use AWS Transit Gateway to route replication traffic between the instances and enable AWS Shield Advanced for protection.

Question 11

A company is planning to migrate an SAP NetWeaver Java system to AWS. The system uses an Oracle database and runs on AIX. The migration team wants to use a heterogeneous migration to SAP HANA on AWS. Which TWO tasks are required to prepare the target system for the migration? (Choose two.)

Accepted Answer

Ensure the target SAP HANA database is installed on a supported EC2 instance type with sufficient memory.. For a heterogeneous migration of an SAP NetWeaver Java system to HANA on AWS, you must select a supported EC2 instance type with sufficient memory and ensure the target OS is certified for SAP HANA, including the necessary client libraries. These steps ensure the target environment is valid and ready for the migration.

Answer

Convert the SAP NetWeaver Java system to an ABAP system because Java stacks are not supported on SAP HANA.

Answer

Use the SAP HANA database migration option (DMO) with SUM to combine the migration and the Java stack upgrade.

Answer

Run the SAP HANA database migration using the SAP HANA Migration Cockpit for Java stacks.

Question 12

A company is planning to migrate a large SAP Business Warehouse (BW) on SAP HANA system to AWS. The database is 6 TB and the company has a 10 Gbps AWS Direct Connect connection. The migration team wants to move the initial data set efficiently and then keep it current until cutover. Which TWO actions should the team take? (Choose two.)

Accepted Answer

Create an AWS Snowball Edge job to ship the SAP HANA data and log volumes to AWS, then configure SAP HANA System Replication after the device is imported.. For a 6 TB SAP HANA migration with a 10 Gbps Direct Connect, the team can either stream the initial data with SAP HANA System Replication over the link or use AWS Snowball Edge to ship the bulk data offline and then enable replication for the delta. Both approaches keep the target current until cutover while respecting the size of the data set and the available bandwidth.

Answer

Use AWS DataSync to copy the SAP HANA data and log files to Amazon EFS, then mount the EFS file system on the target EC2 instance and start SAP HANA.

Answer

Take an Amazon EBS snapshot of the on-premises SAP HANA volumes and restore it directly to the target EC2 instance over Direct Connect.

Answer

Configure AWS Database Migration Service (AWS DMS) with a full-load task to replicate the SAP HANA tables to Amazon RDS for SAP HANA.

Question 13

A company is migrating a large SAP Business Warehouse (BW) system on SAP HANA to AWS. The source system is 10 TB in size, and the migration must be completed within a maintenance window of 8 hours. The network bandwidth between the on-premises data center and AWS is 1 Gbps, and the company wants to minimize data transfer time. Which AWS service should be used to transfer the initial data set to Amazon S3, and then restore it to Amazon EBS volumes for SAP HANA?

Accepted Answer

AWS Snowball Edge. For large data sets that must be transferred within a short window, AWS Snowball Edge is appropriate because it avoids network bandwidth limitations. The data is copied to the device, shipped to AWS, and then uploaded to Amazon S3. From there, it can be restored to Amazon EBS volumes for SAP HANA. Online services like DataSync or Transfer Family would take too long given the 1 Gbps bandwidth.

Answer

AWS DataSync

Answer

AWS Storage Gateway

Answer

AWS Transfer Family

Question 14

A company is migrating its SAP ERP Central Component (ECC) system running on IBM Db2 to AWS. The SAP application servers will be moved first to Amazon EC2, and the database will be migrated later using a near-zero-downtime approach. The database is 4 TB and the network link between on-premises and AWS is 500 Mbps. The company wants to minimize the cutover window and avoid a full database export/import. Which migration approach for the database is MOST appropriate?

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with change data capture (CDC) to replicate the Db2 database to Amazon RDS for Db2.. AWS DMS with change data capture supports continuous replication from IBM Db2 to Amazon RDS for Db2, enabling a minimal cutover window. The source database remains available while the full load and ongoing changes are replicated, and the final switchover requires only a brief application outage. This meets the requirement to avoid a full export/import and minimize downtime.

Answer

Use SAP Database Migration Option (DMO) with SUM to migrate directly to SAP HANA on AWS.

Answer

Use SAP homogeneous system copy with SWPM export/import over the network.

Answer

Use AWS Snowball Edge to ship a database backup to AWS and restore it on Amazon EC2.

Question 15

A company is migrating an SAP NetWeaver ABAP system to AWS. The source system runs on an AIX server with a non-Unicode kernel. The target will be a homogeneous system copy to an EC2 instance running SUSE Linux Enterprise Server for SAP Applications. The SAP application team wants to keep the same SAP SID and hostname. Which migration method should be used?

Accepted Answer

Use SAP SWPM with the 'Homogeneous System Copy' option and a target system installation based on the source system's database backup.. A homogeneous system copy is the correct approach when the database type remains the same and only the OS or platform changes. It preserves the SAP SID and hostname using SWPM, which handles the necessary adaptations such as kernel replacement and database backup restore. The other options either change the database type, use a replication technology not applicable to the source, or rely on a block-level tool that lacks SAP-specific post-processing.

Answer

Use SAP SWPM with the 'Heterogeneous System Copy' option and export/import via SAP migration monitor.

Answer

Use AWS Application Migration Service (MGN) to replicate the entire on-premises server to an EC2 instance, then reinstall SAP on the target.

Answer

Use the SAP HANA System Replication to replicate the source database to the target, then perform a system rename.
