PAS-C01 Practice Test 20 — 15 Questions

Question 1

A company runs SAP HANA on AWS and needs to perform a backup of the HANA database to Amazon S3. Which AWS service should be used to orchestrate the backup and ensure consistency?

Accepted Answer

AWS Backup with pre- and post-backup scripts for application-consistent backups.. AWS Backup supports SAP HANA on EC2 with pre- and post-scripts for application-consistent backups. Option B is wrong because S3 Lifecycle policies manage object lifecycle, not backups. Option C is wrong because DLM manages EBS snapshots, not application-consistent backups. Option D is wrong because Storage Gateway is for hybrid storage, not SAP HANA backups.

Answer

Amazon S3 Lifecycle policies to transition backups to Glacier.

Answer

Amazon Data Lifecycle Manager (DLM) to schedule EBS snapshots.

Answer

AWS Storage Gateway file gateway to back up to S3.

Question 2

An SAP administrator is configuring high availability for SAP HANA on AWS. Which TWO components are essential for a Pacemaker-based cluster?

Accepted Answer

A quorum device (e.g., STONITH). A quorum device (e.g., STONITH) is essential for a Pacemaker-based cluster because it provides fencing, which ensures that a failed or partitioned node cannot continue to access shared resources or cause data corruption. STONITH (Shoot The Other Node In The Head) acts as the cluster's final arbiter, forcibly isolating or powering off an unresponsive node to maintain data integrity and prevent split-brain scenarios.

Answer

An Application Load Balancer

Answer

Amazon Route 53 health checks

Answer

Amazon CloudWatch alarms

Question 3

An SAP system running on AWS experiences periodic performance degradation. Analysis shows that the issue occurs when an on-premises monitoring system polls the SAP application server. Which AWS service can help mitigate this by caching or throttling requests?

Accepted Answer

AWS WAF. (AWS WAF) is correct because AWS WAF can rate-limit incoming requests from specific IP addresses, reducing the load caused by frequent polling from the on-premises monitoring system. Option A (Amazon Route 53) is a DNS service and cannot throttle or cache application-level requests. Option C (Amazon CloudFront) caches content but is not designed for application-level throttling of requests to an SAP application server. Option D (Elastic Load Balancing) distributes traffic but does not provide request throttling or rate limiting.

Answer

Amazon Route 53

Answer

Amazon CloudFront

Answer

Elastic Load Balancing

Question 4

An SAP administrator runs the AWS CLI command shown in the exhibit for an EC2 instance used as an SAP HANA database server. The server has two EBS volumes attached: a root volume (/dev/xvda) and a data volume (/dev/sdf). Based on the output, what will happen when the instance is terminated?

Accepted Answer

The root volume will be deleted, and the data volume will persist.. The AWS CLI command `describe-instances` output shows that the root volume (`/dev/xvda`) has `DeleteOnTermination` set to `true` (default), while the data volume (`/dev/sdf`) has `DeleteOnTermination` set to `false`. When the EC2 instance is terminated, only volumes with `DeleteOnTermination=true` are automatically deleted. Therefore, the root volume will be deleted, and the data volume will persist as an unattached EBS volume in the same Availability Zone.

Answer

The instance cannot be terminated because DeleteOnTermination is set inconsistently.

Answer

Both volumes will be deleted.

Answer

Both volumes will persist.

Question 5

A company is implementing SAP S/4HANA on AWS and wants to ensure that the system is backed up properly. They need to back up the HANA database and the application layer. Which approach is recommended for backing up the HANA database?

Accepted Answer

Use the AWS Backint agent to back up HANA to Amazon S3. The AWS Backint agent is the recommended and supported method for backing up SAP HANA databases on AWS. It integrates directly with SAP HANA's native backup interface (backint for SAP HANA) to stream backup data to Amazon S3, ensuring consistent, incremental, and catalog-aware backups without relying on file-system-level snapshots.

Answer

Use EBS snapshots for the HANA data volumes

Answer

Configure an S3 lifecycle policy to archive the HANA log files

Answer

Use AWS Backup with a backup plan that includes the HANA instance

Question 6

An SAP administrator is setting up a disaster recovery (DR) site for SAP S/4HANA in a different AWS Region. To minimize data loss, which THREE strategies should be implemented? (Choose THREE.)

Accepted Answer

Set up automated EBS snapshots of HANA volumes and copy them to the DR region.. Automated EBS snapshots of HANA volumes can be copied to the DR region using AWS Backup or custom scripts, providing point-in-time recovery with minimal data loss. This strategy ensures that persistent data is asynchronously replicated across regions, which is a standard approach for SAP disaster recovery.

Answer

Use EBS Multi-Attach volumes to share disks between regions.

Answer

Use Amazon CloudFront to cache HANA data in the DR region.

Question 7

Which TWO AWS services can be used to monitor the performance of an SAP system running on EC2?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch (C) is correct because it provides detailed monitoring of EC2 instances, including CPU, memory, disk I/O, and network metrics, which are essential for tracking SAP system performance. Amazon CloudWatch Logs (D) is correct because it allows you to collect, monitor, and analyze log files from SAP applications and the underlying OS, enabling you to detect errors, performance bottlenecks, and system health issues in real time.

Answer

AWS CloudTrail

Answer

AWS Shield

Answer

AWS Config

Question 8

An SAP administrator notices that the SAP application server is experiencing high latency when reading from the shared /sapmnt directory mounted from an Amazon EFS file system. The EFS file system is in General Purpose performance mode and uses Bursting throughput mode. The administrator checks CloudWatch metrics and sees that BurstCreditBalance is near zero. What is the most cost-effective solution to address the latency?

Accepted Answer

Enable Provisioned Throughput mode on the EFS file system. The BurstCreditBalance is near zero, indicating the file system has exhausted its burst credits under Bursting throughput mode. Enabling Provisioned Throughput mode allows you to specify a consistent throughput level independent of the file system's size, eliminating reliance on burst credits and resolving the latency for the /sapmnt directory. This is the most cost-effective solution as it avoids the need to increase storage size (Option A) or migrate to a different storage service.

Answer

Increase the size of the EFS file system to increase the burst credit balance

Answer

Mount the /sapmnt directory from an Amazon EBS gp3 volume instead

Answer

Change the EFS performance mode to Max I/O

Question 9

An SAP administrator needs to monitor the disk I/O performance of EBS volumes attached to an SAP HANA instance. Which AWS service should be used to capture the average read latency and queue depth metrics?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch provides the metrics necessary to monitor disk I/O performance, including `VolumeReadOps`, `VolumeQueueLength`, and `VolumeReadBytes` for EBS volumes. These metrics allow you to calculate average read latency (by dividing `VolumeReadBytes` by `VolumeReadOps`) and directly observe queue depth via `VolumeQueueLength`, making it the correct service for SAP HANA disk I/O monitoring.

AWS CloudTrail

Question 10

An SAP system uses a shared file system via Amazon FSx for Windows File Server. The system administrators report that file locks are not being released properly, causing application errors. What is the most likely cause and solution?

Accepted Answer

Enable the file lock duration feature on the FSx file system to automatically release stale locks.. Amazon FSx for Windows File Server supports a file lock duration feature that can be configured to automatically release stale file locks after a specified timeout. This directly addresses the issue of locks not being released properly, which is a common cause of application errors in SAP systems relying on shared file systems.

Answer

Increase the throughput capacity of the FSx file system.

Answer

The file system is using NFSv3 protocol; switch to NFSv4.

Answer

The file system is using Amazon S3 as the backing store; migrate to EFS.

Question 11

An SAP Basis administrator needs to automate the start and stop of SAP application servers on AWS to reduce costs during non-business hours. The instance must be stopped (not terminated) to preserve the data. Which AWS service can be used to schedule the start and stop?

Accepted Answer

AWS Instance Scheduler. AWS Instance Scheduler is a solution that uses AWS Lambda and Amazon CloudWatch Events (Amazon EventBridge) to automatically start and stop EC2 instances based on a defined schedule. For SAP Basis administrators, this allows stopping (not terminating) SAP application server instances during non-business hours, preserving all data on the attached EBS volumes. The solution supports tagging instances with schedule tags, making it ideal for cost optimization without data loss.

Answer

AWS Auto Scaling

Answer

Amazon CloudWatch Alarms

Answer

AWS Systems Manager Maintenance Windows

Question 12

An SAP Basis administrator is migrating an SAP NetWeaver system from on-premises to AWS. They want to minimize downtime during the migration of the database. Which AWS service is best suited for this?

Accepted Answer

AWS Database Migration Service (DMS). AWS Database Migration Service (DMS) is best suited for migrating SAP NetWeaver databases with minimal downtime because it supports heterogeneous and homogeneous database migrations with ongoing replication. DMS can perform a full load of the database and then continuously replicate changes from the source to the target using change data capture (CDC), allowing the source database to remain operational until the cutover. This minimizes downtime to just the final switchover window, which is critical for SAP systems.

Question 13

A company is using AWS Systems Manager Patch Manager to patch a fleet of EC2 instances. The instances are in a patch group and have the SSM Agent installed. After a patching operation, the operations team notices that some instances did not apply the patches. The instances show a status of 'Failed' in the Patch Manager console. Which TWO steps should the team take to troubleshoot and resolve the issue? (Choose TWO.)

Accepted Answer

Verify that the SSM Agent on the failed instances is running and is able to communicate with the Systems Manager service.. If the SSM Agent is not running or cannot communicate with the AWS Systems Manager service, Patch Manager cannot execute the patching commands. The agent must be in a healthy state and have network connectivity (e.g., via VPC endpoints or internet gateway) to receive the patch baseline and report status. Option D is correct because the AWS-RunPatchBashelline SSM document execution history in Run Command provides detailed logs and error messages for each instance, allowing the team to identify why the patching failed, such as missing dependencies or timeout issues.

Answer

Assign the patch baseline to the instance IDs directly.

Answer

Ensure that the instances have the appropriate IAM role that allows them to be patched.

Answer

Configure a Maintenance Window for the patching operation.

Question 14

An SAP administrator needs to back up the SAP HANA database daily with a retention period of 30 days. The backups must be stored in a cost-effective manner and be instantly accessible for recovery. Which AWS service should be used?

Accepted Answer

Amazon S3 Standard. Amazon S3 Standard provides durable, cost-effective storage with immediate access, ideal for SAP HANA database backups that require a 30-day retention and instant recovery. Option A is incorrect because Amazon S3 Glacier has retrieval delays (minutes to hours) that do not meet the 'instantly accessible' requirement. Option C is incorrect because Amazon S3 Glacier Deep Archive has very long retrieval times (hours to days), unsuitable for instant recovery. Option D is incorrect because Amazon EBS Snapshots are designed for EC2 block-level volumes, not for directly storing HANA database backups as files.

Answer

Amazon S3 Glacier

Answer

Amazon S3 Glacier Deep Archive

Answer

Amazon EBS Snapshots

Question 15

A company is migrating an SAP HANA database to AWS. The system requires a high-performance storage solution with low latency for database files, and the storage must be scalable without downtime. Which AWS storage solution should the company use for the SAP HANA data volume?

Accepted Answer

Amazon EBS io2 Block Express. Amazon EBS io2 Block Express is the correct choice because it provides up to 256,000 IOPS per volume with sub-millisecond latency, meeting SAP HANA's strict performance requirements for data volumes. It also supports Elastic Volumes, allowing you to scale storage capacity and performance without downtime, which is critical for production SAP HANA systems.
