The correct actions are enabling data compression, using AWS Direct Connect, and employing multiple threads for the migration task. Data compression reduces the volume of data transferred over the wire, directly mitigating the impact of high network latency by shrinking the payload. AWS Direct Connect establishes a dedicated, private network path, bypassing the public internet to lower latency and jitter. Using multiple threads parallelizes the data stream, allowing the migration to push more data concurrently despite latency bottlenecks. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of practical latency mitigation strategies during a Database Migration Service (DMS) task—a common scenario where candidates mistakenly choose to resize the target instance, which only improves processing power, not network speed. A helpful memory tip is "Compress, Connect, Concur" to recall the three pillars: compress data, connect directly, and run concurrent threads.
DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. 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 an on-premises SQL Server database to Amazon RDS for SQL Server. During the migration, the DBA notices that the network latency between the source and target is high. Which THREE actions can the DBA take to reduce the impact of network latency on migration performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use multiple parallel tasks in AWS DMS
Options A, C, and D are correct. Using AWS Direct Connect provides a dedicated network connection, reducing latency. Compressing data reduces the amount of data transferred, mitigating latency impact. Using multiple threads parallelizes the data transfer, improving throughput. B is wrong because increasing the instance size does not reduce network latency. E is wrong because using a VPN may introduce additional overhead.
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 RDS instance
Why it's wrong here
Instance size affects compute and storage, not network latency.
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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
