PAS-C01 Technology Practice Question
An SAP system is running on an EC2 instance with a single Amazon EBS volume for data and log files. The database administrator wants to increase the IOPS performance without changing the instance type. Which action should be taken?
⚠ Common exam trap
Watch out — candidates often confuse EBS optimization (which improves network throughput for EBS) with increasing the volume's IOPS performance, leading them to select Option B, but EBS optimization does not change the volume's IOPS limit.

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
✓
Modify the EBS volume to provisioned IOPS (io1/io2).
The correct action is to modify the EBS volume to use provisioned IOPS (io1 or io2), as this directly increases the IOPS performance of the volume without changing the instance type. The current single EBS volume is likely a gp2 or gp3 type, which has a baseline IOPS limit; switching to io1/io2 allows you to specify a higher, consistent IOPS level that meets the SAP database's performance requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Modify the EBS volume to provisioned IOPS (io1/io2).
Why this is correct
You can modify an EBS volume to increase IOPS, including switching to io1/io2.
- ✗
Enable EBS optimization on the EC2 instance.
Why it's wrong here
EBS optimization is typically enabled by default on supported instances.
- ✗
Change the EC2 instance type to a larger size.
Why it's wrong here
Changing instance type may increase network/CPU but not necessarily EBS IOPS.
- ✗
Migrate the data to an instance store volume.
Why it's wrong here
Instance store is ephemeral and not suitable for persistent data.
