Accepted Answer

RAID 10. Option A is correct because RAID 10 (striping + mirroring) provides both performance and redundancy, recommended for HANA data. Option B is wrong because RAID 0 provides no redundancy. Option C is wrong because RAID 5 has write penalty. Option D is wrong because RAID 6 has higher write penalty.

Answer

RAID 5

Answer

RAID 0

Answer

RAID 6

Question 2

A company is running an SAP S/4HANA system on AWS. The system experiences high memory usage. The administrator wants to monitor the SAP HANA memory consumption and set alarms for when memory usage exceeds 85% of available memory. Which steps should the administrator take to achieve this? (Choose THREE.)

Accepted Answer

Use SAP HANA SQL queries to monitor memory usage and publish custom metrics to CloudWatch.. Options A, C, D are correct. A: CloudWatch agent collects OS-level metrics including memory. C: HANA provides detailed metrics via SQL views. D: CloudWatch alarms can trigger actions. Option B is wrong because CloudWatch does not directly query HANA. Option E is wrong because SNS alone does not provide monitoring.

Answer

Configure an Amazon SNS topic to send email notifications when memory usage is high.

Answer

Use Amazon CloudWatch Synthetics to monitor HANA memory.

Question 3

A company is deploying SAP NetWeaver on AWS and needs to set up high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The company uses a shared file system for the transport directory. Which components are essential for the HA setup? (Choose TWO.)

Accepted Answer

An internal Application Load Balancer (ALB) to distribute traffic to the ASCS instance.. Options A and D are correct. A: A load balancer is needed for virtual IP. D: AS CS and ERS must be in different AZs for HA. Option B is wrong because ASCS and ERS should be on separate instances. Option C is wrong because Multi-AZ is for RDS, not for ASCS/ERS. Option E is wrong because S3 is not used for transport in this scenario.

Answer

Amazon S3 as the transport directory.

Answer

Both ASCS and ERS instances must run on the same EC2 instance.

Answer

Amazon RDS Multi-AZ for the SAP database.

Question 4

A company is running SAP HANA on an EC2 instance. The administrator needs to ensure that the instance is resilient to an Availability Zone failure. Which actions should the administrator take? (Choose TWO.)

Accepted Answer

Set up SAP HANA System Replication between instances in two Availability Zones.. Options B and D are correct. B: Multi-AZ RDS provides HA for database. D: Cross-AZ replication provides DR. Option A is wrong because auto scaling is for stateless apps. Option C is wrong because EBS snapshots are not for HA. Option E is wrong because CloudWatch does not provide HA.

Answer

Configure Auto Scaling to automatically launch a new instance in another AZ.

Answer

Use Amazon CloudWatch to monitor instance health and trigger a recovery.

Answer

Take daily EBS snapshots of the HANA data volume.

Question 5

A company runs a critical SAP application on AWS. The SAP team needs to reduce network latency between application servers and the database. Which AWS service should be used to achieve this?

Accepted Answer

Placement Groups (cluster). Option B is correct because placement groups, specifically cluster placement groups, provide low-latency network performance by placing instances in a single Availability Zone with high-bandwidth, low-latency connections. Option A is incorrect because VPC Peering connects networks but doesn't guarantee low latency between instances. Option C is incorrect because AWS Global Accelerator improves global traffic routing but not within a region. Option D is incorrect because Route 53 is a DNS service.

Answer

Amazon Route 53

Answer

AWS Global Accelerator

Answer

VPC Peering

Question 6

An SAP administrator notices that the SAP HANA database on an r5.8xlarge instance is experiencing high swap usage. The instance has 256 GB of RAM. The SAP HANA memory usage is 200 GB. What is the most likely cause?

Accepted Answer

The swap space is too small for the HANA workload. Option C is correct because SAP HANA requires a swap space equal to at least the amount of RAM for HANA to function correctly during memory overcommit scenarios. Option A is incorrect because 200 GB is within the 256 GB RAM limit, so memory is not exhausted. Option B is incorrect because swap is not disabled by default. Option D is incorrect because HANA typically uses huge pages, not swap, for memory allocation.

Answer

The instance memory is exhausted

Answer

HANA is using huge pages instead of swap

Answer

Swap is disabled on the instance

Question 7

A company is migrating an SAP ERP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The solution must use a shared file system for the SAP transport directory. Which combination of AWS services should be used?

Accepted Answer

Amazon EFS for the transport directory and two EC2 instances with a floating IP. Option D is correct because Amazon EFS provides a shared NFS file system for the transport directory, and using two EC2 instances in an active/passive configuration with a floating IP (e.g., via Route 53 or Elastic IP reassignment) provides high availability for ASCS/ERS. Option A is incorrect because EBS volumes cannot be attached to multiple instances simultaneously. Option B is incorrect because S3 is not a POSIX-compliant file system for SAP. Option C is incorrect because Amazon FSx for Windows File Server is for Windows workloads, not Linux SAP.

Answer

Amazon FSx for Windows File Server for the transport directory

Answer

Amazon S3 as the transport directory with two application servers

Answer

Amazon EBS volumes attached to both ASCS and ERS instances

Question 8

An SAP system on AWS is experiencing intermittent connectivity issues between the application server and the HANA database. The application team confirms the database is healthy. Which AWS service should be used to analyze network traffic between the two instances?

Accepted Answer

VPC Flow Logs. Option A is correct because VPC Flow Logs capture IP traffic information for network interfaces, helping to identify dropped packets or blocked traffic. Option B is incorrect because CloudTrail logs API calls, not network traffic. Option C is incorrect because Config records resource configurations. Option D is incorrect because CloudWatch logs application and system logs, not network flows.

Answer

AWS Config

Answer

AWS CloudTrail

Answer

Amazon CloudWatch Logs

Question 9

A company wants to automate the installation of SAP HANA on AWS using CloudFormation. Which AWS resource should be used to run a script that downloads and installs SAP HANA software on an EC2 instance after the instance is launched?

Accepted Answer

AWS::CloudFormation::CreationPolicy with cfn-signal. Option C is correct because AWS CloudFormation CreationPolicy with a cfn-signal script can be used to run custom scripts after instance launch. Option A is incorrect because cfn-init is used to install packages and files, but for complex installations like SAP HANA, a more robust signaling mechanism is needed. Option B is incorrect because EC2 User Data runs once at launch but does not provide a built-in way for CloudFormation to wait for completion. Option D is incorrect because Lambda cannot directly run scripts on EC2 without additional orchestration.

Answer

AWS::CloudFormation::Init (cfn-init)

Answer

AWS Lambda function triggered by EC2 state change

Answer

EC2 User Data

Question 10

An SAP system running on AWS is configured with a Multi-AZ RDS for SAP HANA database. The primary database fails, but the automatic failover does not occur. What is the most likely reason?

Accepted Answer

Multi-AZ is not supported for RDS for SAP HANA. Option B is correct because Multi-AZ for RDS for SAP HANA is not supported; RDS for SAP HANA does not have Multi-AZ capability. Option A is incorrect because RDS does not use Elastic IPs. Option C is incorrect because Multi-AZ is not a paid option; it incurs costs but is not disabled by billing. Option D is incorrect because RDS for HANA does not use EBS snapshots for replication.

Answer

The Multi-AZ configuration was not paid for

Answer

The standby instance was not configured with EBS snapshots

Answer

The primary instance does not have an Elastic IP attached

Question 11

An SAP administrator needs to back up SAP HANA database to Amazon S3. Which AWS service or feature should be used to automate this backup?

Accepted Answer

SAP HANA Backup and Recovery with Backint. Option B is correct because the SAP HANA Backup and Recovery feature can back up directly to S3 via the Backint agent. Option A is incorrect because S3 Lifecycle policies manage object retention, not backup initiation. Option C is incorrect because AWS Backup supports some databases but not SAP HANA directly. Option D is incorrect because EBS snapshots capture the entire volume, not just the HANA database, and are not SAP HANA-aware.

Answer

Amazon EBS snapshots

Answer

AWS Backup

Answer

S3 Lifecycle policies

Question 12

A company runs SAP S/4HANA on AWS and needs to ensure that the system can automatically recover from an Availability Zone failure. The solution must use synchronous replication for zero data loss. Which AWS architecture meets these requirements?

Accepted Answer

SAP HANA System Replication with synchronous replication. Option D is correct because SAP HANA System Replication with synchronous replication across Availability Zones ensures zero data loss and automatic failover. Option A is incorrect because Multi-AZ RDS is not supported for HANA. Option B is incorrect because EBS snapshots are asynchronous and do not provide zero data loss. Option C is incorrect because cluster placement groups are within a single AZ and do not provide cross-AZ failover.

Answer

EBS snapshots taken every 5 minutes

Answer

Multi-AZ RDS for SAP HANA

Answer

Cluster placement group spanning two AZs

Question 13

An SAP system on AWS is experiencing slow performance. The SAP team suspects that the Amazon EBS volumes used for the database are not providing sufficient IOPS. Which step should be taken to identify the bottleneck?

Accepted Answer

Monitor the EBS volume metrics in CloudWatch. Option A is correct because Amazon CloudWatch metrics for EBS volumes can show IOPS, throughput, and queue length, helping to identify if the volume is saturated. Option B is incorrect because VPC Flow Logs show network traffic, not disk performance. Option C is incorrect because AWS Trusted Advisor provides best-practice checks but not real-time performance metrics. Option D is incorrect because AWS Config records resource configurations, not performance.

Answer

Use AWS Trusted Advisor to check performance

Answer

Enable VPC Flow Logs to analyze network traffic

Answer

Review the AWS Config rules for EBS

Question 14

Refer to the exhibit. An SAP administrator is reviewing the block device mappings of an EC2 instance. What is the impact of the DeleteOnTermination setting on /dev/sdf?
