PAS-C01 Operations and Maintenance Practice Question
An SAP on AWS environment uses a shared file system with Amazon EFS. The operations team reports slow performance during peak hours. Which configuration change would most likely improve throughput?
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
✓
Increase provisioned throughput
Increasing provisioned throughput on Amazon EFS is a direct configuration change that raises the throughput limit, which most reliably improves performance during peak hours. Bursting throughput is the default mode and cannot be 'enabled' as a change; it automatically allows bursting based on stored data, but during sustained peak usage, provisioned throughput is needed to guarantee higher throughput. Option A (encryption at rest) does not affect performance. Option C (Enable Bursting Throughput) is misleading because bursting is already enabled by default and cannot be turned on as a new configuration; it also does not provide sustained throughput improvement. Option D (Max I/O performance mode) optimizes for high I/O operations but does not directly increase throughput.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable encryption at rest
Why it's wrong here
Enabling encryption at rest protects data but does not impact throughput performance.
- ✓
Increase provisioned throughput
Why this is correct
Increasing provisioned throughput directly raises the throughput limit, providing consistent performance during peak hours.
- ✗
Enable Bursting Throughput
Why it's wrong here
Bursting throughput is the default mode and cannot be 'enabled' as a configuration change; it provides temporary bursts but may not sustain peak performance.
- ✗
Change the performance mode to Max I/O
Why it's wrong here
Max I/O performance mode is designed for high I/O parallelism but does not specifically increase throughput; it may not address the throughput bottleneck.
