PAS-C01 Design of SAP Workloads on AWS Practice Question
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?
⚠ Common exam trap
Candidates often assume increasing gp2 volume size (Option B) is the only way to improve baseline IOPS, overlooking that gp3 provides a simpler, more cost-effective solution that directly addresses burst bucket depletion without requiring storage resizing.
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
✓
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 analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Change the volume type to gp3 and adjust the IOPS and throughput settings.
Why this is correct
gp3 provides baseline performance without burst credits.
- ✗
Increase the size of the gp2 volumes to increase the baseline IOPS.
Why it's wrong here
Increasing size increases baseline IOPS but still uses burst credits; gp3 is a better solution.
- ✗
Move the data to instance store volumes for better performance.
Why it's wrong here
Instance store is ephemeral and not suitable for persistent SAP data.
- ✗
Change the volume type to io1 and provision high IOPS.
Why it's wrong here
io1 is expensive and overprovisioned; gp3 offers a cost-effective solution.
