DBS-C01 Monitoring and Troubleshooting Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 Amazon DynamoDB with global tables. The application is experiencing high write latency in one region. Which THREE factors could contribute to this issue? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replication lag from global tables causing write conflicts.
Option A (network latency), Option C (throttling due to insufficient write capacity), and Option D (replication lag) are correct. Option B is wrong because auto scaling doesn't increase latency; it adds capacity. Option E is wrong because read capacity affects reads, not writes.
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.
✓
Replication lag from global tables causing write conflicts.
Why this is correct
Global tables replicate asynchronously, and conflicts can increase latency.
Related concept
Read the scenario before looking for a memorised answer.
✗
Insufficient read capacity units provisioned for the table.
Why it's wrong here
Read capacity does not affect write latency.
✓
High network latency between the application and the DynamoDB endpoint.
Why this is correct
Network latency directly impacts write latency.
Related concept
Read the scenario before looking for a memorised answer.
✗
The table's auto scaling configuration is set to increase write capacity too aggressively.
Why it's wrong here
Auto scaling adds capacity, not latency.
✓
Insufficient write capacity units provisioned for the table.
Why this is correct
Throttling increases latency.

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
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.
