ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. 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 network engineer is troubleshooting high latency on an AWS Direct Connect connection. The engineer checks the CloudWatch metrics for the virtual interface and sees that 'ConnectionBpsEgress' and 'ConnectionBpsIngress' are both below 50% of the provisioned bandwidth. Which additional metric should be examined to identify potential bufferbloat?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
PauseFrames (802.3x flow control frames)
Option A is correct because 'PauseFrames' indicates that the link is being flow-controlled due to congestion, which can cause bufferbloat. Option B is incorrect because CRAM is a security protocol. Option C is incorrect because CRC errors indicate physical layer issues. Option D is incorrect because latency metrics are not available for Direct Connect at the virtual interface level.
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.
CRAM is used for authentication, not for bufferbloat.
✗
Latency metrics from Amazon CloudWatch
Why it's wrong here
CloudWatch does not provide latency metrics for Direct Connect virtual interfaces.
✓
PauseFrames (802.3x flow control frames)
Why this is correct
High pause frames indicate congestion and bufferbloat.

✗
CRC errors on the physical connection
Why it's wrong here
CRC errors indicate physical layer problems, not bufferbloat.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
