PAS-C01 Operations and Maintenance Practice Test 7 — 15 Questions

Question 1

An SAP HANA database on EC2 is experiencing high I/O latency. The database uses a single EBS volume for /hana/log. The volume is a gp2 volume with 1000 GB size. The administrator notices that the volume's burst balance is depleted. Which action should be taken to improve latency?

Accepted Answer

Change the volume type to Provisioned IOPS SSD (io1) with sufficient IOPS. Option D is correct because switching to io1 provides consistent IOPS without burst balance. Option A (increasing size) would increase baseline IOPS but not eliminate burst dependency. Option B (adding more volumes) may help but is more complex. Option C (using st1) is for throughput, not low latency.

Answer

Change the volume type to Throughput Optimized HDD (st1)

Answer

Add additional gp2 volumes and stripe them in a RAID 0

Answer

Increase the volume size to 2000 GB to double the baseline IOPS

Question 6

A company runs an SAP HANA database on an EC2 instance with a large EBS volume. The operations team receives alerts that the volume's burst balance has dropped to 10%. Which action should be taken to prevent performance degradation?

Accepted Answer

Increase the volume size to increase the baseline IOPS.. Option B is correct because increasing the volume size increases the baseline IOPS and burst balance replenishment rate. Option A is wrong because gp3 volumes do not have burst balance. Option C is wrong because it does not address burst balance. Option D is wrong because it does not affect burst balance.

Answer

Change the volume type to io2 with provisioned IOPS.

Answer

Enable EBS optimization on the instance.

Answer

Convert the volume to gp3.

Question 7

A company is using SAP HANA on AWS and needs to restore a backup to a new HANA instance. Which AWS service should be used to automate the backup and restore process?

Accepted Answer

AWS Backup. Option C is correct because AWS Backup can automate backups of SAP HANA databases using Backint. Option A is wrong because S3 is storage, not automation. Option B is wrong because DLM manages EBS snapshots, not HANA backups. Option D is wrong because CloudFormation is for infrastructure provisioning.

Question 8

An SAP administrator notices that the SAP application server is experiencing high memory utilization. The system uses a cluster of EC2 instances. What is the most cost-effective solution to automatically add an additional application server when memory exceeds 80%?

Accepted Answer

Configure an Auto Scaling group with a scaling policy based on a custom CloudWatch metric for memory utilization.. Option B is correct because Auto Scaling with a custom metric (memory utilization) can scale out based on the threshold. Option A is wrong because CloudWatch alarms alone do not add instances. Option C is wrong because it does not automatically scale. Option D is wrong because scaling based on CPU does not address memory.

Answer

Create a CloudWatch alarm that sends an email to the administrator to manually launch a new instance.

Answer

Use an Auto Scaling group with a scaling policy based on CPU utilization.

Answer

Use AWS Elastic Beanstalk to deploy the application server.

Question 9

A company is migrating an SAP HANA database to AWS and needs to ensure high availability with automatic failover. Which solution meets this requirement with the least administrative overhead?

Accepted Answer

Use AWS SAP HANA Multi-AZ deployment.. Option D is correct because AWS SAP HANA Multi-AZ is a managed service that automatically handles failover. Option A is wrong because manual scripts require administrative overhead. Option B is wrong because it does not provide automatic failover. Option C is wrong because it requires manual intervention.

Answer

Configure SAP HANA System Replication across two EC2 instances in different Availability Zones and use a custom script for failover.

Answer

Deploy a single EC2 instance with an EBS volume and take regular snapshots.

Answer

Use an Application Load Balancer to distribute traffic to multiple HANA instances.

Question 10

A company runs SAP HANA on AWS and wants to monitor the system for potential performance issues. Which metrics should be monitored to detect memory pressure?
