The answer is to change the volume type to io2 and provision sufficient IOPS. This improves EBS write performance for SAP applications because io2 volumes are designed for consistent, low-latency I/O, which directly addresses the high latency issue, whereas gp2 relies on burst credits and baseline IOPS that degrade under sustained writes. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of EBS performance characteristics for SAP workloads, often appearing as a trap where candidates mistakenly increase gp2 volume size or enable EBS optimization, forgetting that m5 instances have this enabled by default. A common pitfall is confusing throughput-oriented st1 volumes with latency-sensitive io2; remember that SAP databases need predictable IOPS, not raw throughput. Memory tip: for SAP, think “io2 for I/O” — provisioned IOPS beats burst credits every time.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SAP application is experiencing high latency when writing to an Amazon EBS volume. The volume is a gp2 type attached to an m5.4xlarge instance. Which change would improve write performance?
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 io2 and provision sufficient IOPS.
Option C is correct: Changing to an io2 volume with provisioned IOPS provides consistent low latency. Option A is wrong because enabling EBS optimization on m5 instances is already enabled by default. Option B is wrong because increasing volume size increases baseline IOPS for gp2, but not as effective as io2. Option D is wrong because changing to st1 is for throughput-intensive workloads, not low latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Increase the size of the gp2 volume to 1 TB.
Why it's wrong here
Increasing size does increase baseline IOPS, but may not achieve required latency.
✗
Change the volume type to st1.
Why it's wrong here
st1 is optimal for sequential throughput, not low latency.
✗
Enable EBS optimization on the EC2 instance.
Why it's wrong here
m5 instances are already EBS-optimized by default.
✓
Change the volume type to io2 and provision sufficient IOPS.
Why this is correct
io2 volumes provide consistent low-latency performance.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
