ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses AWS Transit Gateway to connect multiple VPCs and an on-premises network via Direct Connect. The on-premises network can reach some VPCs but not others. All VPCs are attached to the same Transit Gateway. What should the engineer check first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Transit Gateway route tables and associations.
The Transit Gateway route tables control which VPCs and attachments can communicate. If some VPCs are in a different route table or if propagation is not configured, traffic may not be routed correctly.
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.
✗
The VPC flow logs for the unreachable VPCs.
Why it's wrong here
Flow logs show traffic, but the root cause is likely routing at the Transit Gateway level.
✓
The Transit Gateway route tables and associations.
Why this is correct
Route tables determine the connectivity between attachments; misconfiguration is the likely cause.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
The Direct Connect virtual interface status.
Why it's wrong here
If some VPCs are reachable, the VIF is working.
✗
The BGP session between the on-premises router and the Direct Connect router.
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.

→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.
