The company wants to use SAP HANA system replication for disaster recovery. Which two AWS services or features should be used to ensure the migration meets these requirements? (Choose two.)

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

Accepted Answer

Amazon EBS volumes with Provisioned IOPS (io1 or io2) for SAP HANA data and log files.. To migrate SAP HANA to AWS with high availability and system replication, you need SAP HANA certified EC2 instances and high-performance storage such as Amazon EBS with Provisioned IOPS. These components ensure the required performance and support for system replication. Other options like S3, FSx for Lustre, or Storage Gateway do not meet the specific requirements for SAP HANA system replication.

Answer

Amazon S3 for storing SAP HANA backups and enabling system replication.

Answer

Amazon FSx for Lustre for storing SAP HANA data and log files.

Answer

AWS Storage Gateway to replicate on-premises data to AWS.

Question 2

A company is migrating an SAP NetWeaver Java-based system to AWS. The system uses an Oracle database on-premises. The company wants to migrate to SAP HANA on AWS as part of the migration. Which tool should be used to perform the database migration and SAP system conversion in a single step?

Accepted Answer

SAP Database Migration Option (DMO) of the Software Update Manager (SUM). SAP DMO is the only tool that combines database migration and SAP system conversion in a single step. It is specifically designed for migrating to SAP HANA and is part of the Software Update Manager. The other options either do not support heterogeneous migration or are not SAP-specific tools.

Answer

SAP homogeneous system copy using SWPM

Answer

SAP HANA System Replication

Answer

AWS Schema Conversion Tool (SCT)

Question 3

A company is planning to migrate an SAP ERP Central Component (ECC) system to AWS. The database is Oracle. They want to use AWS Database Migration Service (DMS) for the migration. Which prerequisite must be met for DMS to perform the migration?

Accepted Answer

The source Oracle database must be configured with supplemental logging enabled.. AWS DMS requires supplemental logging on the source Oracle database to capture changes for ongoing replication. This is a mandatory configuration for Oracle sources when using CDC. Other options are not prerequisites; the target can be various databases, the source can remain online, and the replication instance does not need to be in the same AZ.

Answer

The source database must be stopped during the entire migration to ensure consistency.

Answer

The target database must be an Amazon RDS for Oracle instance with the same version as the source.

Answer

The AWS DMS replication instance must be deployed in the same Availability Zone as the source database.

Question 4

A company runs SAP NetWeaver on Amazon EC2 instances behind an Application Load Balancer. The SAP application servers must serve different content based on the URL path, and session persistence is required for the SAP GUI. The company wants to minimize administrative overhead and ensure that the load balancer can route traffic to the correct application server. Which solution should a SAP on AWS specialist recommend?

Accepted Answer

Configure an Application Load Balancer with path-based routing rules and enable sticky sessions using application-based cookie stickiness.. The Application Load Balancer provides layer 7 routing, including path-based rules, and supports application-based cookie stickiness that keeps SAP GUI sessions bound to a specific instance. This combination meets both the routing and session persistence requirements without custom application changes or additional infrastructure, reducing administrative effort.

Answer

Configure a Network Load Balancer with a TCP listener and enable sticky sessions using source IP affinity.

Answer

Use an Application Load Balancer with host-based routing and disable session persistence, relying on the SAP application to store session state in a shared database.

Answer

Deploy a Classic Load Balancer with TCP listeners and enable sticky sessions using duration-based cookies.

Question 5

A company is migrating an SAP NetWeaver ABAP-based system to AWS. The system uses a distributed architecture with a central instance, a database instance, and multiple application servers. The company wants to ensure that the SAP system can be started and stopped automatically in a specific order during maintenance windows. Which AWS service should be used to orchestrate the start and stop of the EC2 instances and ensure the correct sequence?

Accepted Answer

AWS Systems Manager Automation with runbooks.. AWS Systems Manager Automation with runbooks is the appropriate service to orchestrate the start and stop of EC2 instances in a specific order. Runbooks can define steps with dependencies, ensuring that the database instance starts before the application servers, which is critical for SAP system availability. It also integrates with maintenance windows and can be scheduled.

Answer

Amazon EC2 Auto Scaling with lifecycle hooks.

Answer

AWS CloudFormation with nested stacks.

Answer

AWS OpsWorks for Chef Automate with recipes.

Question 6

A company is migrating an SAP ERP system running on IBM Db2 to AWS. The database is currently 5 TB and grows by 10% annually. The company wants to minimize downtime during the migration and avoid re-platforming the database. They plan to use AWS Application Migration Service (AWS MGN) to replicate the entire server, including the database. Which statement accurately describes a limitation or consideration when using AWS MGN for this SAP migration?

Accepted Answer

AWS MGN replicates at the block level, so the database must be quiesced during the final cutover to ensure data consistency.. AWS Application Migration Service replicates block-level data continuously, but for databases like IBM Db2, it cannot guarantee application consistency without quiescing. During the final cutover, you must stop the database to flush all transactions and ensure a consistent state. This step is essential to avoid data corruption and is a key planning consideration for SAP migrations.

Answer

AWS MGN requires the source server to be offline during the initial replication.

Answer

AWS MGN cannot replicate servers with databases larger than 1 TB.

Answer

AWS MGN does not support replication of Oracle databases, but IBM Db2 is supported.

Question 7

A company is deploying SAP S/4HANA on AWS and needs to ensure high availability for the SAP HANA database across two Availability Zones. They plan to use SAP HANA system replication. Which two additional components are required to automate failover and ensure clients reconnect seamlessly? (Choose two.)

Accepted Answer

A cluster manager such as Pacemaker with a STONITH mechanism to manage resources and prevent split-brain.. To automate failover and ensure seamless client reconnection in a SAP HANA system replication setup across two AZs, a cluster manager like Pacemaker with STONITH is required to manage resources and fence failed nodes. Additionally, an overlay IP (e.g., Elastic IP or virtual IP) is needed to allow clients to reconnect to the new primary without manual changes. Other options like ALB or Route 53 are not suitable or sufficient for this purpose.

Answer

Amazon Route 53 with a failover routing policy that points to the primary and secondary instances.

Answer

An Application Load Balancer configured with a target group for the SAP HANA database, with health checks on port 30015.

Answer

SAP HANA's built-in multi-tier system replication with a third site for disaster recovery.

Question 8

A company is running SAP on AWS and wants to automatically recover an unhealthy EC2 instance that hosts their SAP application. Which AWS feature should they configure to automatically restart the instance in the same Availability Zone if it fails?

Accepted Answer

EC2 Auto Recovery. EC2 Auto Recovery is an AWS feature that automatically recovers an impaired EC2 instance by restarting it on new hardware within the same Availability Zone. It is configured via a CloudWatch alarm that triggers the 'recover' action when status checks fail, making it the correct choice for automatic recovery of a single SAP application instance.

Answer

Cluster Placement Group

Answer

Auto Scaling group

Answer

Lifecycle Hook

Question 9

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 10

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 11

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.

Question 12

A company is migrating an SAP NetWeaver ABAP system from an on-premises data center to AWS. The source system has a high volume of batch jobs that run overnight and must complete within the same maintenance window. The migration team needs to size the target Amazon EC2 instances to match the on-premises CPU throughput. Which AWS tool should they use to collect and analyze CPU utilization and memory metrics from the source system before migration?

Accepted Answer

AWS Application Discovery Service. AWS Application Discovery Service is designed to discover on-premises servers and collect utilization data, including CPU and memory, which is essential for right-sizing EC2 instances. For an SAP NetWeaver migration where batch jobs must complete within a fixed window, accurate sizing based on historical performance prevents under-provisioning. The other services focus on replication, tracking, or database migration and do not provide the required metrics.

Answer

AWS Migration Hub

Answer

AWS Application Migration Service (AWS MGN)

Answer

AWS Database Migration Service (AWS DMS)

Question 13

A company is migrating its SAP NetWeaver ABAP system to AWS and must cut over during a maintenance window of only four hours. The source system's database is 2.8 TB on SAP HANA, and the business cannot tolerate a full re-load of the database after cutover. The team wants the shortest possible downtime while keeping the target system synchronized with the source until the final switch. Which migration approach should the team use?

Accepted Answer

Use SAP HANA system replication to continuously replicate from on-premises to an Amazon EC2 HANA instance, then perform a takeover during the maintenance window.. The decisive constraints are a very short cutover window and the prohibition on a full database re-load. SAP HANA system replication maintains a live, consistent copy of the database on the target Amazon EC2 instance, so cutover becomes a takeover that completes quickly. The other approaches either stop the source for extended periods, transport the full dataset during the window, or lack SAP HANA-aware consistency.

Answer

Perform an SAP homogeneous system copy using SWPM export/import with the target database running on Amazon EC2, then re-import the transport requests after cutover.

Answer

Use AWS Application Migration Service to continuously replicate the on-premises SAP application and database servers, then launch test and cutover instances in AWS.

Answer

Back up the source SAP HANA database with hdbsql and restore the backup into an Amazon EC2 HANA instance during the maintenance window, then point the SAP application servers at the new host.

Question 14

A company is migrating an SAP ERP Central Component (ECC) system to AWS. The system runs on SAP MaxDB and will be migrated to SAP HANA on an Amazon EC2 instance. The migration team decides to use the SAP Database Migration Option (DMO) with SUM. During the DMO run, the team encounters an error related to the SAP kernel version. The source system is running kernel release 7.21. What must be done to resolve this error and allow the DMO run to proceed?

Accepted Answer

Upgrade the SAP kernel to at least release 7.22 before starting the DMO run.. DMO requires a minimum SAP kernel release, typically 7.22 or higher for HANA migration. The source system's kernel 7.21 is too old, so it must be upgraded before the DMO run. This upgrade is a prerequisite check in SUM and ensures compatibility with the DMO tools and the target database.

Answer

Install a second SAP system with a newer kernel and use it as a bridge for the migration.

Answer

Apply the latest SAP HANA client libraries to the source system.

Answer

Configure the DMO to use a different kernel release by specifying a parameter in SUM.

Question 15

A company is designing a disaster recovery solution for a critical SAP HANA database running on AWS. The primary site is in us-east-1 and the recovery site must be in us-west-2. The database must have a Recovery Point Objective (RPO) of less than 15 minutes and a Recovery Time Objective (RTO) of less than 2 hours. Which approach meets these requirements with the least operational overhead?

Accepted Answer

Configure SAP HANA System Replication (HSR) in active/standby mode between the primary and secondary regions.. SAP HANA System Replication (HSR) in active/standby mode is the native, AWS-recommended disaster recovery solution for SAP HANA databases. It provides synchronous or asynchronous replication of the entire in-memory database to a standby instance in us-west-2, enabling an RPO of less than 15 minutes (asynchronous mode) and an RTO of under 2 hours through a controlled takeover. This approach minimizes operational overhead because it is built into SAP HANA, requires no external services, and automates log shipping and data synchronization.

Answer

Use AWS Backup to take snapshots of the HANA data volume every 5 minutes and copy them to us-west-2.

Answer

Use Amazon S3 Cross-Region Replication to copy HANA data files to us-west-2.

Answer

Set up AWS Database Migration Service (DMS) with ongoing replication from the primary to a secondary HANA database.
