PAS-C01 Operations and Maintenance Practice Question
A company runs a production SAP HANA database on AWS using an EC2 instance with EBS volumes. The database is experiencing high latency during peak hours. The operations team needs to identify the root cause. Which steps should the team take to diagnose the issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Monitor the EBS volume queue length and latency using Amazon CloudWatch metrics.
Amazon CloudWatch provides metrics such as EBS volume queue length (depth) and average latency, which are key indicators of I/O bottlenecks. High queue depth with corresponding latency spikes suggests that the EBS volume is overwhelmed and needs adjustment (e.g., switching to Provisioned IOPS). Option A is incorrect because migrating to Provisioned IOPS without diagnosing the root cause may not solve the issue and increases cost unnecessarily. Option C is incorrect because moving SAP HANA to Amazon RDS for SAP is not a direct solution for latency and introduces migration complexity. Option D is incorrect because increasing instance size without analyzing I/O patterns may not address the bottleneck and can also increase costs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Migrate the EBS volumes to Provisioned IOPS SSD (io1) immediately.
Why it's wrong here
Switching volume types without understanding the workload may not resolve the latency issue.
- ✓
Monitor the EBS volume queue length and latency using Amazon CloudWatch metrics.
Why this is correct
CloudWatch metrics for EBS can identify performance bottlenecks.
- ✗
Move the SAP HANA database to Amazon RDS for SAP.
Why it's wrong here
Amazon RDS does not support SAP HANA.
- ✗
Increase the instance size to improve performance.
Why it's wrong here
Scaling without diagnosis may not address the root cause and could be costly.
