PAS-C01 Technology Practice Question
A company runs an SAP HANA database on an EC2 instance with a 2 TB EBS gp3 volume. The instance type is r5.8xlarge. To improve disk performance for high-throughput write operations, the SAP administrator wants to increase IOPS. Which TWO actions should the administrator take to achieve the required IOPS? (Choose two.)
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
✓
Modify the volume to provision additional IOPS up to 16,000.
Gp3 volumes allow independent provisioning of IOPS up to 16,000, which directly increases performance for high-throughput write operations. Option E is correct because increasing the volume size also increases the baseline IOPS for gp3 (baseline is 3 IOPS/GiB). Option A is wrong because T2 unlimited credits apply to burstable instances, not EBS performance. Option B is wrong because st1 is a throughput-optimized HDD volume, not suitable for high IOPS. Option D is wrong because EBS optimization is enabled by default on r5 instances and is not a configurable action.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the instance to use T2 unlimited credits.
Why it's wrong here
T2 unlimited relates to CPU credits, not EBS IOPS.
- ✗
Change the volume type to st1 (throughput optimized HDD).
Why it's wrong here
st1 is for throughput, not high IOPS.
- ✓
Modify the volume to provision additional IOPS up to 16,000.
Why this is correct
gp3 allows independent IOPS provisioning.
- ✗
Enable EBS optimization on the EC2 instance.
Why it's wrong here
EBS optimization is always enabled on r5 instances.
- ✓
Increase the EBS volume size to increase baseline IOPS.
Why this is correct
Increasing volume size increases baseline IOPS for gp3.
