Quick Answer
The answer is to configure multiple DMS tasks to load different tables in parallel. This approach directly addresses the need to speed up DMS migration parallel tasks by distributing the full load across several concurrent processes, effectively multiplying throughput to fit the 4-hour downtime window. AWS DMS can run multiple tasks simultaneously against the same source and target, so splitting the 10 TB PostgreSQL workload into smaller, parallel streams maximizes the 1 Gbps Direct Connect bandwidth and reduces total load time from 6 hours to under 4. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of DMS performance tuning and the trade-offs between parallel tasks, CDC, and alternative methods like Snowball or VPN. A common trap is assuming you must reduce data volume or switch to offline tools, but the core concept is that DMS parallelism is the fastest way to saturate network capacity without adding latency or manual steps. Memory tip: think “divide and conquer” — parallel tasks split the table load, not the data size.
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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 migrating its on-premises data warehouse to Amazon Redshift. The existing system uses PostgreSQL and has 10 TB of data. The migration must be completed within a 4-hour downtime window. The company has a 1 Gbps AWS Direct Connect connection. After starting the migration using AWS DMS with a full load and CDC, the full load takes 6 hours. What should the company do to meet the downtime window?
Configure multiple DMS tasks to load different tables in parallel.
Parallelism improves speed.
Use AWS Snowball Edge to transfer the data physically.
Why wrong: Slower and more complex.
Reduce the amount of data by archiving older records.
Why wrong: Cannot change data volume.
Use AWS VPN instead of Direct Connect for higher bandwidth.
Why wrong: VPN is not faster.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure multiple DMS tasks to load different tables in parallel.
Option C is correct because parallel loading increases throughput. Option A is wrong because reducing data is not feasible. Option B is wrong because VPN is slower. Option D is wrong because Snowball adds latency and manual steps.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.
