Question 5

A company runs SAP on AWS and wants to implement a disaster recovery solution with a Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 15 minutes. The primary site is in us-east-1, and the DR site is in us-west-2. Which strategy meets these requirements for SAP HANA database?

Accepted Answer

Configure SAP HANA System Replication across regions. Option D is correct because HANA System Replication with log shipping can achieve RPO of minutes and RTO within hours. Option A is incorrect because EBS snapshots cannot achieve 15-minute RPO. Option B is incorrect because S3 cross-region replication is for files, not live HANA replication. Option C is incorrect because DMS is for heterogeneous migrations, not real-time HANA replication.

Answer

Use AWS Database Migration Service (DMS) for ongoing replication

Answer

Take EBS snapshots every 15 minutes and copy them to us-west-2

Answer

Use Amazon S3 Cross-Region Replication for HANA data files

Accepted Answer

Amazon CloudWatch. Option A is correct - CloudWatch can monitor metrics and send alarms. Option C is correct - SNS can send notifications. Option B is incorrect - CloudTrail logs API calls, not health. Option D is incorrect - Config tracks configuration changes. Option E is incorrect - Athena is for querying data.

Answer

AWS Config

Answer

AWS CloudTrail

Answer

Amazon Athena

Question 9

A company is running an SAP HANA database on an EC2 instance with a single EBS volume for /hana/data. The performance team reports high write latency during peak hours. Which change would most effectively reduce write latency without compromising data durability?

Accepted Answer

Configure multiple EBS volumes in a striped RAID 0 array for the /hana/data directory. Option B is correct because using multiple EBS volumes with striping increases I/O throughput and reduces latency by distributing writes. Option A (increasing volume size) may not improve latency. Option C (provisioned IOPS) could help but is more expensive and less effective than striping for this scenario. Option D (moving to GP2) is a downgrade in performance.

Answer

Switch the EBS volume type to Provisioned IOPS SSD (io1) with high IOPS

Answer

Increase the size of the EBS volume to gain more baseline IOPS

Answer

Move the /hana/data directory to a General Purpose SSD (gp2) volume

Question 10

An SAP administrator notices that the SAP application server is failing health checks in the Elastic Load Balancer (ELB) target group. The application server runs on an EC2 instance behind an Application Load Balancer. The health check path is /sap/public/ping. What is the most likely cause of the failure?

Accepted Answer

The SAP application (e.g., disp+work) is not running on the instance. Option C is correct because if the SAP application is not running, it cannot respond to the health check. Option A (security group) would cause connection timeout, not health check failure. Option B (wrong path) would return 404 but still be considered unhealthy. Option D (SAProuter) is not relevant to application health.

Answer

SAProuter is blocking the health check requests

Answer

The health check path is incorrectly configured in the target group

Answer

The EC2 instance security group does not allow inbound traffic from the ELB

Question 11

A company runs SAP ERP on AWS using a Multi-AZ RDS for SAP HANA database. The operations team needs to automate the rotation of the database master password. Which AWS service should be used to securely store and rotate the password?

Accepted Answer

AWS Secrets Manager. Option D is correct because AWS Secrets Manager can automatically rotate RDS database credentials. Option A (Systems Manager Parameter Store) can store secrets but does not support automatic rotation. Option B (IAM) does not manage database passwords. Option C (CloudHSM) is for hardware security modules, not password rotation.

Answer

AWS Systems Manager Parameter Store

Answer

AWS CloudHSM

Answer

AWS Identity and Access Management (IAM)

Question 12

An SAP Basis administrator is monitoring the health of an SAP HANA database on AWS. The administrator wants to receive alerts when the CPU utilization of the HANA instance exceeds 90% for 5 consecutive minutes. Which combination of AWS services should be used?

Amazon CloudWatch metrics and CloudWatch Alarms with Amazon SNS. Option A is correct: CloudWatch collects metrics and Alarms trigger notifications via SNS. Option B (Lambda) is not needed for simple alarm. Option C (Config) is for compliance. Option D (X-Ray) is for tracing.

Answer

AWS X-Ray and Amazon CloudWatch Logs

Answer

AWS CloudTrail and AWS Lambda

Answer

AWS Config and Amazon Simple Email Service (SES)

Question 13

An SAP system on AWS is experiencing slow performance. The operations team suspects a memory bottleneck on the SAP HANA database. Which CloudWatch metric should be monitored to confirm memory pressure?

Accepted Answer

SwapUsage (custom metric from HANA). Option C is correct because SAP HANA uses swap space when memory is full; high swap usage indicates memory pressure. Option A (CPU) is not memory. Option B (Disk) is storage. Option D (Network) is network.

Answer

CPUUtilization

Answer

DiskReadOps

Answer

NetworkIn

Question 14

A company needs to back up its SAP HANA database running on Amazon RDS. The database is 500 GB. What is the recommended approach for backups?

Accepted Answer

Enable automated backups and configure the backup retention period. Option B is correct because RDS automatically performs automated backups and enables point-in-time recovery. Option A (EBS snapshots) is not recommended for RDS. Option C (SAP HANA Studio backup) is not integrated with AWS. Option D (manual S3 copy) is inefficient.

Answer

Create manual EBS snapshots of the RDS instance
