PAS-C01 Technology Practice Question
An SAP system on AWS is experiencing high latency for database transactions. The system uses a single EBS volume for the SAP HANA data volume. The operations team needs to improve I/O performance without changing the instance type. Which action should be taken?
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
✓
Switch to EBS io2 Block Express volumes
Switching to EBS io2 Block Express volumes provides higher IOPS and lower latency compared to gp3. Increasing volume size does not necessarily improve latency. Using a single volume for log and data is not recommended. Enabling EBS optimization is already enabled on current generation instances.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single EBS volume for both data and log
Why it's wrong here
Combining data and log on one volume can cause contention and increase latency.
- ✓
Switch to EBS io2 Block Express volumes
Why this is correct
io2 Block Express offers sub-millisecond latency and high IOPS, suitable for SAP HANA.
- ✗
Increase the EBS volume size to gain more IOPS
Why it's wrong here
Increasing size may increase baseline IOPS but not necessarily reduce latency.
- ✗
Enable EBS optimization on the instance
Why it's wrong here
EBS optimization is enabled by default on current generation instances and does not solve high latency.
