- A
Use Amazon Kinesis Data Streams as an intermediate target for CDC.
Why wrong: Using Amazon Kinesis Data Streams as an intermediate target adds complexity and does not directly address the large transaction handling issue in DMS.
- B
Increase the DMS replication instance size to provide more memory and CPU.
Increasing the DMS replication instance size provides more memory and CPU, allowing the instance to process large transactions more efficiently and keep up with CDC changes without falling behind.
- C
Modify the DMS task settings to increase MaxFileSize and decrease the CommitRate.
Why wrong: Modifying MaxFileSize and decreasing CommitRate is not the primary solution; decreasing CommitRate means less frequent commits, which could exacerbate issues with large transactions. The more direct approach is to scale the instance.
- D
Disable foreign key constraints on the target Aurora database.
Why wrong: Disabling foreign key constraints might help with data loading but does not resolve CDC transaction issues.
DEA-C01 AWS DMS Task Settings Practice Question
This DEA-C01 practice question tests your understanding of data ingestion and transformation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: aWS DMS Task Settings. 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 a 5 TB SQL Server database to Amazon Aurora PostgreSQL. The migration is using full load plus CDC. After the full load completes, the ongoing replication task is failing with errors related to large transactions on the source. The team needs to ensure that CDC continues without falling behind. What should the team do?
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
Increase the DMS replication instance size to provide more memory and CPU.
Increasing the DMS replication instance size provides more memory and CPU, enabling the instance to process large transactions more efficiently and keep up with CDC changes without falling behind. Option C (modifying MaxFileSize and decreasing CommitRate) is not the best solution because decreasing CommitRate means less frequent commits, which could worsen the problem by accumulating more data per commit. The more direct approach is to scale the instance vertically to handle the load.

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
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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.
