A company is running SAP Business Suite on AWS using an Oracle database. They need to migrate the Oracle database to SAP HANA as part of an SAP S/4HANA conversion. The current Oracle database size is 5 TB and runs on an r5.8xlarge instance. The target HANA database will run on an r5.24xlarge instance. The company wants to minimize downtime. What is the best approach to migrate the data?

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

Accepted Answer

Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO) to migrate and upgrade in one step.. SAP provides the Software Update Manager (SUM) with DMO (Database Migration Option) to perform the migration and upgrade in one step, minimizing downtime. Option A (native Oracle export/import) is time-consuming. Option B (AWS DMS) is not fully supported for SAP HANA as target. Option C (SAP Landscape Transformation) is for data replication but not for a one-step migration with upgrade. Option D is correct.

Answer

Use AWS Database Migration Service (DMS) to continuously replicate data from Oracle to HANA, then switch over.

Answer

Use SAP Landscape Transformation (SLT) to replicate data in real-time from Oracle to HANA.

Answer

Use Oracle Data Pump to export the database and import into HANA using SAP HANA studio.

Question 2

A company runs SAP ERP on AWS with an Oracle database on an r5.4xlarge instance. The system experiences performance degradation during month-end closing. Monitoring shows high CPU and I/O wait on the database server. The storage is EBS gp2 volumes. The company plans to migrate to SAP HANA in the future. What immediate change should be made to improve performance?

Accepted Answer

Change the EBS volumes from gp2 to gp3 to improve I/O performance and throughput.. Changing the EBS volumes from gp2 to gp3 (C) is correct because gp3 volumes provide baseline performance of 3,000 IOPS and 125 MiB/s throughput regardless of volume size, whereas gp2 performance scales with volume size and may be insufficient for I/O-intensive workloads like month-end closing. This change can be done online without downtime and directly addresses the high I/O wait. It is also a cost-effective immediate improvement.

Answer

Implement AWS RDS Oracle read replicas to offload reporting queries.

Answer

Migrate the database to SAP HANA immediately to improve performance.

Answer

Increase the EC2 instance size to r5.8xlarge to provide more CPU and memory.

Question 3

An SAP Basis administrator is configuring a high availability setup for SAP HANA on AWS using HANA System Replication (HSR) with automatic failover. The architecture includes a primary HANA node in us-east-1a and a secondary in us-east-1b. The administrator uses a Network Load Balancer (NLB) with a floating IP for the HANA virtual IP address. After a failover test, the secondary node becomes primary, but client applications cannot connect to the database. What is the most likely cause?

Accepted Answer

The NLB target group is not configured to include the secondary node's IP address.. With HSR and an NLB using a floating IP, the NLB target group must contain the secondary node so that after failover the NLB routes client traffic to the new primary. If the target group only includes the primary node's IP, the NLB has no healthy target after failover, and clients cannot connect. The most likely cause is that the secondary node's IP was never added to the target group (or the target group was not updated by the failover automation).

Answer

The security group for the NLB does not allow inbound traffic on port 3<0xEB><0x9C><0x9D><0xEB><0x9E><0x80>13.

Answer

The SAP HANA client is using a DNS name that does not resolve to the NLB endpoint.

Answer

The secondary HANA node is in a different subnet and not routable from the NLB.

Question 4

A company is designing a disaster recovery (DR) strategy for its SAP environment on AWS. The primary site is in us-east-1 and the DR site in us-west-2. The SAP HANA database is 3 TB and uses HANA System Replication (HSR) in async mode. The RPO requirement is 15 minutes. What is the most cost-effective way to meet the RPO?

Accepted Answer

Configure HANA System Replication in asynchronous mode over AWS Direct Connect.. HANA System Replication (HSR) in asynchronous mode over AWS Direct Connect provides a low-latency, reliable network path that can achieve an RPO of 15 minutes without the performance penalty of synchronous replication. Asynchronous replication sends committed transactions to the DR site without waiting for acknowledgment, which is suitable for the 3 TB HANA database and meets the RPO requirement cost-effectively by avoiding the need for expensive, high-bandwidth dedicated connections or frequent full backups.

Answer

Take full database backups to Amazon S3 every 15 minutes.

Answer

Use EBS snapshots every 5 minutes to replicate data to DR region.

Answer

Use HANA System Replication in synchronous mode to ensure zero data loss.

Question 5

A company runs SAP S/4HANA on AWS using a distributed architecture with separate instances for the database (DB) and application (ASCS, PAS, AAS). The application servers are in an Auto Scaling group. After a recent scaling event, users report that they cannot log in to the system. The SAP dispatcher logs show that the application servers cannot connect to the message server. What is the most likely cause?

Accepted Answer

The new application servers are not registered in the SAP message server's configuration.. In a distributed SAP S/4HANA architecture, application servers (ASCS, PAS, AAS) must be registered with the SAP message server so they can discover each other and route logon requests. When an Auto Scaling group launches new application server instances, those instances must be added to the message server's configuration (via the message server's `ms.sapmsa` configuration or the `sapmsa` profile) — otherwise they cannot connect and users cannot log in. The dispatcher logs explicitly showing inability to connect to the message server point to this registration gap.

Answer

The database connection string in the new application servers points to the wrong endpoint.

Answer

The SAP licenses are exhausted and need to be updated.

Answer

The security group of the application servers is not allowing outbound traffic to the DB server.

Question 6

An SAP architect is designing a new SAP S/4HANA system on AWS. The system must be PCI DSS compliant. The architect plans to use AWS KMS for encryption at rest and AWS CloudTrail for audit logging. The database will be SAP HANA on an r5.24xlarge instance with EBS gp3 volumes. What additional step is required to meet PCI DSS encryption requirements?

Accepted Answer

Enable SAP HANA data volume encryption using the HANA database engine.. PCI DSS requires encryption of cardholder data at rest, and for SAP HANA on AWS this means enabling SAP HANA data volume encryption using the HANA database engine in addition to EBS-level encryption. AWS KMS encrypts the underlying EBS volumes, but SAP HANA's own data volume encryption provides application-level encryption that satisfies the requirement for the database itself.

Answer

Store all SAP audit logs in Amazon S3 with server-side encryption.

Answer

Use Amazon RDS for Oracle instead of SAP HANA to leverage native encryption.

Answer

Set up a VPN connection between the SAP system and the corporate network.

Question 7

A company runs SAP ERP on AWS with a Microsoft SQL Server database. The system is experiencing slow batch job processing. The database server is an r5.8xlarge instance with EBS gp2 volumes. Monitoring shows high disk queue length on the data and log volumes. What change will most likely improve batch job performance?

Accepted Answer

Move the tempdb files to a dedicated EBS io2 volume with high IOPS.. High disk queue length on the data and log volumes of a SQL Server instance running SAP indicates an I/O bottleneck. Moving tempdb to a dedicated EBS io2 volume with high provisioned IOPS isolates tempdb I/O from the data and log volumes and provides the low-latency, high-IOPS throughput that batch jobs need, directly relieving the bottleneck.

Answer

Migrate the SQL Server database to Amazon RDS for SQL Server.

Answer

Store the tempdb on an instance store volume.

Answer

Upgrade the EC2 instance to r5.12xlarge.

Question 8

A company is running SAP HANA on AWS using a scale-out architecture with multiple worker nodes. The system is used for real-time analytics. Recently, query performance has degraded. The HANA administrator notices that the data is not evenly distributed across nodes. What is the best course of action?

Accepted Answer

Redistribute the tables across nodes using HANA's table partitioning features.. SAP HANA's table partitioning features allow you to redistribute data across worker nodes in a scale-out architecture, addressing the root cause of uneven data distribution. This rebalancing improves query performance by ensuring parallel processing and minimizing data movement between nodes. The HANA administrator can use commands like ALTER TABLE ... REBALANCE or partition management to achieve even distribution.

Answer

Increase the memory allocation for the HANA database.

Answer

Add more worker nodes to the scale-out cluster to distribute the load.

Answer

Upgrade the EC2 instance type of all nodes to a memory-optimized type.

Question 9

A company is planning to migrate its SAP ECC system to SAP S/4HANA on AWS. The current system uses an IBM Db2 database on-premises. The target system will use SAP HANA as the database. The company wants to perform the migration with minimal downtime. Which tool or method should be used?

Accepted Answer

Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO).. SAP Software Update Manager (SUM) with the Database Migration Option (DMO) is the only tool that combines both the system upgrade from SAP ECC to SAP S/4HANA and the database migration from IBM Db2 to SAP HANA in a single, integrated process. DMO uses a trigger-based replication approach to minimize downtime by migrating data in the background while the source system remains operational, then performing a short final cutover. This is the officially recommended SAP methodology for heterogeneous migrations with minimal downtime.

Answer

Use IBM Db2 native tools to export the database and import into HANA.

Answer

Use AWS Database Migration Service (DMS) to replicate data from Db2 to HANA.

Answer

Use SAP Landscape Transformation (SLT) to replicate data in real-time.

Question 10

A company is deploying SAP S/4HANA on AWS and must choose the most appropriate storage for the HANA data and log volumes. The workload requires consistent sub-millisecond latency, high IOPS, and the ability to snapshot for backup. The SAP HANA database is running on an r5.8xlarge EC2 instance. Which storage solution should be used?

Accepted Answer

Amazon EBS io2 volumes with provisioned IOPS and a size that meets SAP HANA storage requirements. SAP HANA requires storage with consistent low latency and high IOPS for data and log volumes. Amazon EBS io2 volumes are designed for such demanding database workloads, offering sub-millisecond latency and the ability to provision IOPS independently of volume size. They also support snapshots for backup. Other EBS types like gp3, st1, or io2 with multi-attach do not meet the specific performance and exclusivity requirements for a production HANA deployment on AWS.

Answer

Amazon EBS io2 Block Express volumes with provisioned IOPS and multi-attach enabled

Answer

Amazon EBS st1 volumes with 1,000 MiB/s throughput and 40,000 IOPS

Answer

Amazon EBS gp3 volumes with 16,000 IOPS and 1,000 MiB/s throughput

Question 11

A company is deploying a new SAP S/4HANA production system on AWS. The SAP HANA database will run on a single EC2 instance using an x2gd.16xlarge instance with 1 TB of memory. The company requires a storage layout that follows SAP's recommendations for performance and durability. Which storage configuration should be used for the HANA data and log volumes?

Accepted Answer

Use a single io2 Block Express volume for data and a separate io2 Block Express volume for log, without RAID.. SAP HANA on AWS requires separate storage for data and log, and the chosen volumes must deliver consistent high IOPS and low latency. io2 Block Express volumes are designed for such demanding workloads and provide the necessary performance and durability without the added complexity of RAID. Using a single volume per workload aligns with SAP's guidelines and AWS best practices.

Answer

Use one io2 Block Express volume for data and a separate io2 Block Express volume for log, each in a RAID 0 configuration across multiple volumes.

Answer

Use a single gp3 EBS volume for both data and log, sized at 4 TB with 16,000 IOPS.

Answer

Use an instance store volume for data and an io2 Block Express volume for log.

Question 12

A company runs an SAP NetWeaver ABAP application server on a single c5.4xlarge EC2 instance in a single Availability Zone. The company wants to protect the application server against an AZ failure with a recovery time objective of 15 minutes and a recovery point objective of 5 minutes, while minimizing cost. Which approach should be used?

Accepted Answer

Launch a pilot-light EC2 instance in the secondary AZ from an AMI that contains the SAP installation, keep it stopped, and start it during a failover after attaching a replicated EBS volume.. A pilot-light deployment keeps a pre-built SAP application server instance in the secondary AZ that can be started quickly, which satisfies the 15-minute RTO. Replicating the EBS volume keeps data loss within the 5-minute RPO. This approach is less expensive than a fully running standby and more reliable than snapshot restore or load balancing alone because the SAP instance identity is already prepared.

Answer

Use AWS Backup to take hourly EBS snapshots of the application server volume and restore the volume to a new EC2 instance in the secondary AZ during a failover.

Answer

Deploy the application server across two Availability Zones using an Auto Scaling group with a launch template that includes the SAP installation, and configure a secondary application server in the standby AZ.

Answer

Configure an Application Load Balancer with the existing application server as the only target and enable cross-zone load balancing to provide automatic failover to another AZ.

Question 13

A company is deploying a new SAP S/4HANA system on AWS. The SAP HANA database must use persistent storage that provides sub-millisecond latency and supports multi-attach for a scale-out configuration. The company also needs to minimize operational overhead for storage management. Which storage solution should be used for the HANA data and log volumes?

Accepted Answer

Amazon EBS io2 Block Express volumes with Multi-Attach enabled. For SAP HANA on AWS, the data and log volumes require persistent, high-performance block storage with sub-millisecond latency and support for Multi-Attach in scale-out scenarios. Amazon EBS io2 Block Express volumes meet these requirements and are SAP-certified for HANA. They provide the necessary IOPS and throughput while being a managed service that reduces operational overhead compared to self-managed storage solutions.

Answer

Amazon S3 bucket mounted as a file system using AWS Storage Gateway

Answer

Amazon FSx for Lustre file system mounted on all HANA nodes

Answer

Instance store NVMe SSDs on each HANA node with application-level replication

Question 14

A company is deploying a new SAP S/4HANA system on AWS. The SAP HANA database will run on an x2gd.16xlarge EC2 instance with 1 TB of memory. The company requires that the database storage provide consistent sub-millisecond latency and support 64,000 IOPS. The storage must also allow independent scaling of capacity and performance. Which storage solution meets these requirements?

Accepted Answer

Amazon Elastic Block Store (Amazon EBS) io2 Block Express volumes with 64,000 IOPS provisioned. SAP HANA on AWS requires storage that delivers consistent low latency and high IOPS, with the ability to scale capacity and performance independently. Amazon EBS io2 Block Express volumes are specifically designed for such demanding database workloads, supporting up to 256,000 IOPS and sub-millisecond latency. Provisioning 64,000 IOPS meets the stated requirement, making io2 Block Express the appropriate choice for this scenario.

Answer

Amazon Elastic File System (Amazon EFS) with Max I/O performance mode

Answer

Instance store volumes on the x2gd.16xlarge instance

Answer

Amazon Elastic Block Store (Amazon EBS) gp3 volumes with 64,000 IOPS provisioned

Question 15

A company is designing a disaster recovery strategy for its SAP S/4HANA system on AWS. The system runs on a single EC2 instance with an EBS volume for data and log. The RTO is 15 minutes and the RPO is 5 minutes. The company wants to minimize data loss and ensure rapid recovery in case of a region-wide failure. Which TWO strategies should be implemented? (Choose two.)

Accepted Answer

Configure SAP HANA System Replication to a secondary EC2 instance in a different AWS Region, using asynchronous mode with log shipping every 5 minutes.. For region-wide disaster recovery with an RTO of 15 minutes and RPO of 5 minutes, two effective strategies are SAP HANA System Replication to a different region with asynchronous log shipping and a pilot light approach using cross-region EBS snapshots and a pre-configured AMI. Both enable rapid recovery in another region while minimizing data loss. Other options either do not protect against region-wide failure, are too slow, or are not applicable to AWS-based SAP systems.

Answer

Use AWS Storage Gateway to replicate on-premises data to AWS, and fail over to an on-premises SAP system.

Answer

Set up SAP HANA System Replication (HSR) to a secondary EC2 instance in another Availability Zone, with synchronous mode for zero data loss.

Answer

Use Amazon EBS snapshots replicated to a secondary region with AWS Backup, and restore from snapshots in the DR region.
