Quick Answer
The answer is to increase the size of the EBS volumes to improve baseline throughput. This is correct because for gp2 and gp3 volumes, throughput scales directly with volume size; larger volumes provide a higher baseline throughput limit, directly resolving EBS throughput limits for SAP batch jobs that are I/O intensive and writing large amounts of data. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that EBS performance is not just about IOPS but also throughput, and that resizing is a valid scaling action for gp2/gp3. A common trap is to confuse this with instance store, which is ephemeral and unsuitable for persistent SAP data, or to suggest Multi-AZ or read replicas, which do not increase write throughput. Memory tip: think of EBS throughput as a pipe—wider volumes (larger size) mean a wider pipe for data to flow through.
This PAS-C01 practice question tests your understanding of technology. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 system on AWS is experiencing slow performance for batch jobs. The jobs are I/O intensive and write large amounts of data to EBS volumes. CloudWatch metrics show that the EBS volumes are reaching their throughput limits. Which action will MOST effectively improve performance?
Add read replicas to offload read traffic.
Why wrong: Does not improve write throughput.
Increase the size of the EBS volumes to improve baseline throughput.
Larger gp2/gp3 volumes have higher throughput.
Use Multi-AZ for the database.
Why wrong: HA feature, not performance.
Move the data to instance store volumes.
Why wrong: Ephemeral, data loss risk.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Increase the size of the EBS volumes to improve baseline throughput.
Option C is correct because increasing the volume size of gp2/gp3 increases baseline throughput. Option A is wrong because instance store is ephemeral and not suitable for persistent data. Option B is wrong because read replicas do not help with write throughput. Option D is wrong because Multi-AZ does not increase throughput.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Add read replicas to offload read traffic.
Why it's wrong here
Does not improve write throughput.
Increase the size of the EBS volumes to improve baseline throughput.
Why this is correct
Larger gp2/gp3 volumes have higher throughput.
Related concept

Why it's wrong here
Ephemeral, data loss risk.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
