A company is planning to migrate its SAP HANA database to AWS. They require high availability with automatic failover in less than 30 seconds. Which AWS service should be used to meet this requirement?

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

Accepted Answer

Amazon Route 53. Amazon Route 53 can be configured with health checks and DNS failover to automatically redirect traffic to a standby SAP HANA database in a different Availability Zone or region when the primary fails. With a low TTL (e.g., 5 seconds) and active-passive routing, failover can occur in under 30 seconds, meeting the high availability requirement.

Answer

Elastic Load Balancing

Answer

AWS Direct Connect

Answer

AWS Global Accelerator

Question 2

A company runs SAP on AWS and needs to implement a disaster recovery strategy for their SAP NetWeaver system. The primary site is in us-east-1, and the DR site is in us-west-2. They want to minimize data loss and recovery time. Which approach meets these requirements?

Accepted Answer

Use SAP HANA System Replication in asynchronous mode across regions.. SAP HANA System Replication in asynchronous mode across regions is the correct approach because it provides near-zero recovery point objective (RPO) with minimal impact on primary system performance, while enabling rapid failover to the DR region in us-west-2. Asynchronous replication is suitable for cross-region scenarios where network latency would make synchronous mode impractical, and it meets the requirement to minimize both data loss and recovery time for SAP NetWeaver.

Answer

Use SAP HANA System Replication in synchronous mode across regions.

Answer

Use AWS Backup to back up the SAP HANA database and restore in us-west-2.

Answer

Use Amazon S3 cross-region replication for SAP HANA data files.

Question 3

An SAP administrator notices that the SAP HANA database on an EC2 instance is experiencing high I/O latency. The instance is using EBS gp2 volumes. Which change would most effectively reduce I/O latency for the SAP HANA data volume?

Accepted Answer

Switch to io2 Block Express EBS volumes for the data volume.. Io2 Block Express volumes provide consistent, high-performance IOPS with sub-millisecond latency, which is critical for SAP HANA data volumes. Unlike gp2, which relies on burst credits and has variable performance, io2 Block Express delivers predictable low latency and up to 256,000 IOPS per volume, directly addressing the high I/O latency issue.

Answer

Use instance store SSDs for the SAP HANA data volume.

Answer

Increase the size of the EBS gp2 volume to increase baseline IOPS.

Answer

Configure RAID 0 across multiple gp2 volumes.

Question 4

A company wants to run SAP S/4HANA on AWS and needs to ensure that the SAP application and database are deployed according to AWS best practices. Which deployment method should they use?

Accepted Answer

AWS Launch Wizard for SAP. AWS Launch Wizard for SAP is the correct deployment method because it provides a guided, best-practice-based deployment experience specifically for SAP S/4HANA, automatically provisioning EC2 instances, storage, and networking while validating SAP requirements such as kernel compatibility, sizing, and high availability. It reduces manual effort and errors by integrating directly with AWS services like Amazon EBS and Elastic Load Balancing, ensuring compliance with SAP on AWS best practices.

Answer

Manual deployment using EC2 and RDS

Answer

AWS Quick Start for SAP

Answer

AWS CloudFormation with custom templates

Question 5

An SAP Basis administrator is setting up an SAP HANA database in a Multi-AZ deployment on AWS. They need to ensure that the database remains available during an Availability Zone failure. Which AWS services should be used together to achieve this?

Accepted Answer

SAP HANA System Replication and Amazon Route 53. SAP HANA System Replication (HSR) provides synchronous or asynchronous replication of HANA databases across Availability Zones, ensuring data consistency and failover capability. Amazon Route 53 with health checks and DNS failover routing automatically redirects client traffic to the standby HANA instance in the secondary AZ when the primary fails, together achieving Multi-AZ high availability for SAP HANA.

Answer

AWS CloudWatch alarms and AWS Lambda

Answer

Auto Scaling groups and Elastic Load Balancer

Answer

Amazon RDS Multi-AZ and Route 53

Question 6

A company has an SAP HANA database running on a r5.8xlarge EC2 instance with 3.5 TB of data. They want to back up the database to Amazon S3 using Backint. What is the most cost-effective and performant backup strategy?

Accepted Answer

Use multiple parallel Backint streams to a single S3 bucket with S3 Standard storage.. Backint is the native SAP HANA backup integration that sends backup data directly to Amazon S3. Using multiple parallel Backint streams maximizes throughput by leveraging S3's high request rate limits, and S3 Standard storage provides the low-latency access needed for frequent backups and restores without incurring retrieval costs. This combination is both cost-effective and performant for a 3.5 TB database.

Answer

Use EBS snapshots and copy them to S3.

Answer

Use multiple parallel Backint streams to multiple S3 buckets with S3 Glacier storage.

Answer

Use a single Backint stream to one S3 bucket with S3 Standard storage.

Question 7

A company is running SAP ERP on AWS and wants to ensure that their SAP system is backed up according to SAP best practices. Which backup method should they use for the SAP HANA database?

Accepted Answer

SAP HANA Backint to Amazon S3. SAP HANA Backint to Amazon S3 is the correct backup method because it integrates directly with SAP HANA's native backup interface (Backint), allowing SAP to manage backup and restore operations natively. This approach supports SAP best practices for HANA database backups, including full, incremental, and differential backups, and leverages Amazon S3 for durable, scalable storage without requiring external scripting or manual snapshot coordination.

Answer

AWS Backup service

Answer

EBS snapshots of the data volumes

Answer

Amazon S3 replication

Question 8

An SAP administrator needs to configure high availability for SAP NetWeaver AS ABAP. They plan to use AWS services. Which combination of services is required?

Accepted Answer

Amazon EFS and Pacemaker on EC2. SAP NetWeaver AS ABAP high availability on AWS requires shared storage for the /sapmnt and /usr/sap/trans directories, which Amazon EFS provides via NFSv4, and a cluster manager like Pacemaker on EC2 to orchestrate failover between the primary and secondary application servers. This combination ensures that the SAP central services (ASCS and ERS) can fail over seamlessly in the event of an instance or availability zone failure.

Answer

AWS Global Accelerator and Auto Scaling

Answer

Elastic Load Balancing and Amazon Route 53

Answer

Amazon EBS Multi-Attach volumes

Question 9

A company is running SAP HANA on AWS and wants to encrypt the EBS volumes at rest. They also need to manage the encryption keys themselves. Which solution should they use?

Accepted Answer

Use AWS KMS with a customer managed key (CMK). AWS KMS with a customer managed key (CMK) allows the company to have full control over the encryption keys used for EBS volume encryption, including key rotation, access policies, and disabling or deleting the key. This meets the requirement to manage the encryption keys themselves while still leveraging AWS KMS for key management and auditing.

Answer

Enable EBS encryption with the default AWS managed KMS key

Answer

Use AWS CloudHSM to store keys

Answer

Use AWS Systems Manager Parameter Store

Question 10

A company is planning to migrate their SAP HANA database to AWS. Which TWO of the following are valid EC2 instance types for SAP HANA? (Choose 2.)

Accepted Answer

x1e.32xlarge. (x1e.32xlarge) is correct because it is part of the X1e instance family, which is specifically certified by SAP for production HANA workloads. These instances offer high memory (up to 3,904 GiB) and are optimized for large in-memory databases like SAP HANA, meeting the SAP memory and vCPU requirements for OLAP and OLTP scenarios.

Answer

c5.9xlarge

Answer

t3.2xlarge

Answer

i3.8xlarge

Question 11

A company is designing a disaster recovery solution for SAP S/4HANA. They need to meet an RPO of 15 minutes and an RTO of 2 hours. Which THREE components should be included in the DR plan? (Choose 3.)

Accepted Answer

SAP HANA System Replication in async mode. SAP HANA System Replication in async mode is correct because it can achieve an RPO of 15 minutes by asynchronously replicating log buffers from the primary to the DR HANA instance, and combined with a pre-configured DR system, it supports an RTO of 2 hours. This native SAP replication mechanism is optimized for HANA databases and avoids the overhead of storage-level snapshots or third-party tools.

Answer

EBS snapshots taken every 15 minutes

Answer

AWS CloudEndure Disaster Recovery

Question 12

An SAP administrator is creating an IAM policy for an automation script that needs to start and stop a specific SAP HANA EC2 instance. The policy is shown in the exhibit. However, the script fails with an authorization error when trying to start the instance. What is the most likely cause?

Accepted Answer

The ARN in the resource element does not match the actual instance ID.. The policy uses a resource ARN that specifies a particular instance ID. If the ARN does not match the actual instance ID of the SAP HANA EC2 instance, the `ec2:StartInstances` action will fail with an authorization error because IAM evaluates the resource ARN against the instance being started. AWS IAM policies require an exact match between the resource ARN in the policy and the instance ID for actions that operate on specific resources.

Answer

The policy is missing an effect for the specific instance.

Answer

The policy does not include ec2:DescribeInstances action.

Answer

The script does not have the correct region specified.

Question 13

An SAP administrator runs the AWS CLI command shown in the exhibit to check the configuration of an SAP HANA EC2 instance. The instance is running in us-east-1a. They need to deploy a second SAP HANA instance for high availability in a different Availability Zone. Which Availability Zone should be used?

Accepted Answer

us-east-1b. For SAP HANA high availability, the secondary instance must be deployed in a different Availability Zone within the same AWS Region to achieve multi-AZ resilience. Since the primary instance is in us-east-1a, the correct choice is us-east-1b, which is a distinct Availability Zone in the same region (us-east-1). This ensures low-latency replication and compliance with SAP's requirement for synchronous replication within a single region.

Answer

us-west-2a

Answer

Any Availability Zone

Answer

us-east-1a

Question 14

An SAP administrator configures SAP HANA backup using Backint as shown in the exhibit. The backup job fails with an error indicating that the bucket 'sap-hana-backup-prod' does not exist. The administrator confirms that the bucket name is correct. What is the most likely cause of the failure?

Accepted Answer

The bucket is in a different AWS region than the EC2 instance.. The SAP HANA Backint agent communicates with Amazon S3 using the AWS SDK, which resolves the bucket endpoint based on the region configured in the agent or the instance metadata. If the bucket 'sap-hana-backup-prod' exists in a different AWS region than the EC2 instance, the Backint agent will attempt to access the bucket using the wrong regional endpoint, resulting in a 'bucket does not exist' error. This is a common misconfiguration when the Backint parameter file does not explicitly set the correct region or when the instance's default region differs from the bucket's region.

Answer

The IAM role used by the instance does not have s3:PutObject permission.

Answer

The chunk size is too large for the bucket.

Answer

The bucket has a bucket policy that denies access.

Question 15

A company is designing an SAP HANA multi-node scale-out deployment on AWS. The system requires high bandwidth and low latency between nodes. Which AWS networking feature should be used to meet these requirements?

Accepted Answer

Elastic Fabric Adapter (EFA). Elastic Fabric Adapter (EFA) is correct because it provides OS-bypass capabilities using the Libfabric API, enabling direct memory access (DMA) between SAP HANA nodes. This eliminates kernel overhead, delivering the high bandwidth (up to 100 Gbps per adapter) and ultra-low latency (microsecond-level) required for SAP HANA multi-node scale-out workloads, where inter-node communication is critical for table partitioning and data replication.

Answer

AWS Direct Connect

Answer

Transit Gateway
