PAS-C01 Practice Test 5 — 10 Questions

Question 1

An SAP system on AWS is using Amazon EBS volumes for the database. The company wants to take crash-consistent snapshots of the entire database volume set. Which approach is recommended?

Accepted Answer

Use AWS Backup with pre- and post-scripts for volume groups. AWS Backup with pre- and post-scripts for volume groups is the recommended approach because it orchestrates crash-consistent snapshots across multiple EBS volumes by freezing the application (e.g., SAP HANA) and flushing I/O before the snapshot, then unfreezing after. This ensures all volumes are captured at the same point in time without downtime, which is critical for SAP databases requiring consistency across the entire volume set.

Answer

Stop the instance, take snapshots, then restart

Answer

Use EBS Multi-Attach to attach volumes to a backup instance

Answer

Take snapshots of each volume individually at the same time

Question 2

An SAP HANA system on AWS is experiencing performance degradation. The administrator suspects that the EBS volumes are not providing consistent IOPS. Which AWS tool can be used to monitor the performance of EBS volumes at the volume level?

Accepted Answer

Amazon CloudWatch. Amazon CloudWatch provides detailed metrics for EBS volumes, including `VolumeReadOps`, `VolumeWriteOps`, `VolumeQueueLength`, and `VolumeIdleTime`, which allow administrators to monitor IOPS performance at the individual volume level. By setting CloudWatch alarms on these metrics, you can detect when an EBS volume is not delivering the provisioned IOPS, which is critical for SAP HANA workloads that require consistent, high-throughput storage.

Answer

AWS Trusted Advisor

Question 3

A company is running SAP BusinessObjects on AWS and needs to back up the CMS database (an SAP HANA database) daily. The backup must be stored in Amazon S3 for long-term retention and must be recoverable within 4 hours. Which backup strategy meets these requirements?

Accepted Answer

Configure the SAP HANA Backint agent to back up directly to Amazon S3.. Configuring the SAP HANA Backint agent to back up directly to Amazon S3 meets the requirements because it provides native HANA backup integration with S3 for long-term retention and allows recovery within the 4-hour RTO. Backint is the standard SAP HANA API for third-party backup tools, and AWS supports it via the AWS Backint agent.

Answer

Copy the HANA data files to an Amazon EBS volume in a different Availability Zone.

Answer

Use AWS Backup to create application-consistent backups of the HANA database.

Answer

Take daily EBS snapshots of the HANA volumes.

Question 4

An SAP administrator notices that the SAP application server performance degrades during peak hours. The application servers are running on EC2 instances with gp2 EBS volumes. The administrator suspects the EBS volumes are experiencing burst bucket depletion. Which action should the administrator take to improve performance?

Accepted Answer

Change the volume type to gp3 and adjust the IOPS and throughput settings.. The gp2 volume type uses a credit-based burst model where performance degrades once the burst bucket is depleted, especially under sustained high I/O. Changing to gp3 provides a baseline performance that does not rely on burst credits, and you can independently provision higher IOPS and throughput without increasing storage size, directly addressing the performance degradation during peak hours.

Answer

Increase the size of the gp2 volumes to increase the baseline IOPS.

Answer

Move the data to instance store volumes for better performance.

Answer

Change the volume type to io1 and provision high IOPS.

Question 5

A company wants to migrate its SAP BusinessObjects system to AWS. The system includes a CMS database that runs on Microsoft SQL Server. The company wants to use AWS DMS to migrate the database with minimal downtime. Which migration method should they use?

Accepted Answer

Full load with ongoing replication (change data capture). Full load with ongoing replication (change data capture) performs an initial bulk load and then continuously replicates ongoing changes from the source SQL Server to the target, keeping downtime to a minimum during cutover. This is the standard AWS DMS approach for minimal-downtime migrations of active databases. A one-time full load would require a maintenance window and cause extended downtime.

Answer

Snapshot restore to Amazon RDS

Answer

Full load with one-time restore

Answer

Full load only

Question 6

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 7

The exhibit shows the output of the describe-replication-tasks command for an ongoing migration from SAP HANA to Amazon RDS for MySQL. The task status is 'running' but no data has been transferred after 2 hours. What is the most likely cause?

Accepted Answer

The source endpoint is not accessible from the replication instance. When a DMS replication task shows 'running' but no data has moved for hours, the most common cause is that the replication instance cannot reach the source endpoint — typically due to security group, NACL, routing, or DNS issues. DMS will keep the task in 'running' state while retrying the connection, so the symptom is a stalled task rather than an immediate failure.

Answer

The replication instance has insufficient memory

Answer

The target endpoint is pointing to the wrong database

Answer

The HANA database is not configured as a target

Question 8

A company has deployed SAP S/4HANA on AWS using a single EC2 instance for the HANA database and multiple EC2 instances for the application servers. The system is in production and the company wants to implement high availability for the HANA database to minimize downtime during patching and failures. The HANA database is critical and must have an RTO of less than 5 minutes and an RPO of zero. The current setup uses a single EBS volume for /hana/data and another for /hana/log. The company has two Availability Zones available. Which solution meets the requirements?

Accepted Answer

Configure SAP HANA System Replication with automatic failover to a secondary HANA instance in another AZ.. SAP HANA System Replication (HSR) with automatic failover meets the RTO < 5 minutes and RPO = 0 requirements by synchronously replicating data to a secondary HANA instance in another Availability Zone. Automatic failover ensures the secondary takes over without manual intervention, minimizing downtime during patching or failures. This is the only option that provides synchronous replication with zero data loss and fast failover across AZs.

Answer

Attach the EBS volumes to two EC2 instances using EBS Multi-Attach.

Answer

Use AWS Backup to schedule snapshots every 5 minutes and restore in another AZ if needed.

Answer

Deploy the HANA database on a larger EC2 instance with higher availability SLA.

Question 9

An administrator needs to back up an SAP HANA database running on an EC2 instance. The backup must be stored in a durable, cost-effective storage solution. Which AWS service is best suited for storing the backup files?

Accepted Answer

Amazon S3. Amazon S3 is the best choice for storing SAP HANA backup files because it offers 99.999999999% durability, is cost-effective for long-term backup storage, and integrates natively with SAP HANA via the Backint agent for direct backup to S3. S3 provides scalable object storage that can handle the large volume of SAP HANA data without requiring manual provisioning or lifecycle management.

Answer

Amazon S3 Glacier

Question 10

A company is deploying SAP NetWeaver on AWS and needs to ensure high availability for the ASCS instance. They plan to use a shared file system for the transport directory. Which AWS storage service is most appropriate for this shared file system?

Accepted Answer

Amazon EFS. Amazon EFS provides a fully managed, scalable, and highly available NFS file system that can be mounted concurrently by multiple EC2 instances across multiple Availability Zones. For SAP NetWeaver ASCS high availability, the transport directory (/usr/sap/trans) must be shared between the active and passive ASCS instances, and EFS supports the required NFSv4 protocol with strong consistency and POSIX permissions, making it the most appropriate choice.
