DBS-C01 Management and Operations Practice Question

This DBS-C01 practice question tests your understanding of management and operations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.

Network Topology

Refer to the exhibit. A database administrator runs the AWS CLI command to retrieve CloudWatch metrics for an Amazon RDS DB instance. The output shows a spike in WriteLatency at 10:05 UTC. What is the most likely cause of this spike?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Network Topology

A
The DB instance's gp2 volume has exhausted its burst credits.
Option A is correct because a sudden spike in write latency often indicates that the storage volume has exhausted its burst credits and is now using baseline performance, which may be slower.
B
The DB instance is in the process of taking a snapshot.
Why wrong: Option B is incorrect because a snapshot causes I/O suspension, not necessarily a write latency spike.
C
There is a large number of concurrent connections to the DB instance.
Why wrong: Option C is incorrect because a large number of connections typically causes increased CPU and memory usage, not necessarily a latency spike.
D
The DB instance experienced a Multi-AZ failover.
Why wrong: Option D is incorrect because a Multi-AZ failover would cause a brief downtime, not a latency spike.

Correct answer & explanation

✓

The DB instance's gp2 volume has exhausted its burst credits.

Option A is correct because a sudden spike in write latency often indicates that the storage volume has exhausted its burst credits and is now using baseline performance, which may be slower. Option B is incorrect because taking a snapshot causes I/O suspension, not necessarily a latency spike. Option C is incorrect because a large number of concurrent connections typically causes increased CPU and memory usage, not a latency spike. Option D is incorrect because a Multi-AZ failover would cause a brief downtime, not a latency spike.

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

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Quick reference

AWS S3 Storage Class Comparison

Storage Class	Min Duration	Retrieval	Use Case
S3 Standard	None	Immediate	Frequently accessed data
S3 Standard-IA	30 days	Immediate	Infrequent access, rapid retrieval
S3 One Zone-IA	30 days	Immediate	Non-critical infrequent data
S3 Intelligent-Tiering	None	Immediate–hours	Unknown or changing access patterns
S3 Glacier Instant	90 days	Milliseconds	Archive with instant retrieval
S3 Glacier Flexible	90 days	Minutes–hours	Archive, flexible retrieval
S3 Glacier Deep Archive	180 days	Hours	Long-term compliance archive
