This PAS-C01 practice question tests your understanding of migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

A company is using AWS DMS to migrate an SAP database. The full load is complete, but the CDC latency is high. Which step should the company take to reduce latency?

A
Increase the compute capacity of the DMS replication instance.
A larger replication instance can process CDC faster.
B
Increase the size of the target database instance.
Why wrong: Target size may not be the bottleneck; DMS instance size is more likely.
C
Restart the DMS replication task.
Why wrong: Restarting does not address performance issues.
D
Disable change data capture (CDC) on the source database.
Why wrong: Disabling CDC would stop capturing changes.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the compute capacity of the DMS replication instance.
Option A is correct because increasing the compute capacity of the DMS replication instance provides more resources to process CDC changes, reducing latency. Option B is incorrect because increasing the target database size does not directly affect DMS replication performance. Option C is incorrect because restarting the task does not address the underlying resource constraint and may cause temporary downtime. Option D is incorrect because disabling CDC would stop replication entirely, not reduce latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
