PAS-C01 Practice Test 48 — 15 Questions

Question 1

An operations team needs to monitor the disk space usage of SAP application servers running on EC2. Which combination of AWS services should they use?

Accepted Answer

Amazon CloudWatch agent and Amazon CloudWatch alarms. Amazon CloudWatch agent is required to collect custom metrics like disk space usage from EC2 instances, as the standard CloudWatch metrics only cover CPU, memory, network, and disk I/O. By installing the agent and configuring it to report disk space metrics, you can then set CloudWatch alarms to trigger notifications when thresholds are breached, enabling proactive monitoring of SAP application servers.

Answer

Amazon CloudWatch and AWS CloudTrail

Answer

AWS Lambda and Amazon DynamoDB

Answer

Amazon S3 and Amazon SNS

Question 2

An SAP administrator is setting up backup for an SAP HANA database running on an EC2 instance. The database is 1 TB in size. Which TWO AWS services can be used to create a cost-effective backup strategy?

Accepted Answer

AWS Backup. AWS Backup (option C) is correct because it is a fully managed backup service that can centrally define backup policies, schedules, and retention rules for supported resources including EBS volumes that host the SAP HANA database, enabling a cost-effective, automated strategy. Amazon EBS snapshots (option D) are correct because they capture point-in-time, incremental backups of the EBS volumes underlying the EC2 instance, so only changed blocks are stored after the first snapshot, which is a cost-effective way to protect a 1 TB SAP HANA database. AWS Database Migration Service (option A) is not a backup service; it is used to migrate or replicate databases, so it does not provide a backup strategy. AWS Storage Gateway (option B) is a hybrid storage service for integrating on-premises environments with AWS storage, not a native backup mechanism for an EC2-hosted SAP HANA database. Amazon S3 with lifecycle policies (option E) can store backup files and transition them to cheaper storage classes, but by itself it is not a backup service that creates the SAP HANA database backups, so it is not one of the two services that directly create the backup.

Answer

AWS Database Migration Service (DMS)

Answer

AWS Storage Gateway

Answer

Amazon S3 with lifecycle policies

Question 3

An SAP NetWeaver administrator needs to patch the operating system of an SAP application server running in an Auto Scaling group. The instances are behind an Application Load Balancer. What is the correct procedure to minimize downtime?

Accepted Answer

Use an Auto Scaling rolling update with lifecycle hooks to launch new instances from a patched AMI and gradually deregister old ones.. The correct procedure is to use an Auto Scaling rolling update with lifecycle hooks. This launches new instances from a patched AMI, waits for them to become healthy, and then gradually deregisters and terminates old instances. The Application Load Balancer ensures traffic is only routed to healthy instances, minimizing downtime. Lifecycle hooks allow you to pause the instance launch or termination to perform validation or patching steps, ensuring a controlled rollout.

Answer

Detach one instance from Auto Scaling, patch it, test, then reattach.

Answer

Stop accepting traffic at the ALB, patch all instances manually, then re-enable traffic.

Answer

Terminate all instances at once and let Auto Scaling launch new ones with a patched AMI.

Question 4

An SAP system on AWS is experiencing performance degradation. Amazon CloudWatch metrics show high CPU utilization on the application server, but the database server (RDS) metrics are normal. The application team suspects a memory leak. Which action should the operations team take FIRST to confirm the issue?

Accepted Answer

Install the CloudWatch agent on the application server and enable memory metrics.. CloudWatch cannot see inside the OS without the CloudWatch agent. Installing the agent and collecting memory metrics is the first step to confirm a memory leak. Option A is wrong because CloudWatch does not provide memory metrics by default. Option C is wrong because rebooting is disruptive and does not help diagnose. Option D is wrong because switching to a larger instance is a reactive fix, not diagnostic.

Answer

Review the existing CloudWatch CPU utilization and memory metrics for the application server.

Answer

Reboot the application server and monitor performance after reboot.

Answer

Increase the instance size of the application server to handle the load.

Question 5

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?

Accepted Answer

Amazon CloudWatch metrics and CloudWatch Alarms with Amazon SNS. Amazon CloudWatch metrics can collect CPU utilization from the SAP HANA instance (via the CloudWatch agent or native AWS metrics). CloudWatch Alarms can be configured to trigger when CPU exceeds 90% for 5 consecutive minutes. The alarm can then publish to an Amazon SNS topic to send notifications (e.g., email, SMS). This combination provides the required monitoring and alerting.
