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 company is using AWS Direct Connect to connect its on-premises data center to AWS. The connection is up, but the network team cannot reach resources in a VPC. The virtual interface is in the 'available' state, and BGP session is established. What should the team check next?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the VPC route tables for propagated routes
Since the Direct Connect physical link is up, the virtual interface is available, and the BGP session is established, the issue lies in the routing of traffic within AWS. The most likely cause is that the VPC route tables do not contain the necessary routes (either static or propagated from the Direct Connect virtual private gateway) to direct traffic back to the on-premises network. Checking the VPC route tables for propagated routes is the correct next step to ensure the on-premises CIDR is being advertised and accepted.
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.
✗
Check the on-premises firewall rules
Why it's wrong here
The BGP session is established, so the firewall allows BGP; the issue is likely in route propagation.
✗
Check the BGP authentication
Why it's wrong here
BGP session is established, so authentication is correct.
✓
Check the VPC route tables for propagated routes
Why this is correct
The Direct Connect virtual interface routes must be propagated to the VPC route tables.

✗
Check the Direct Connect physical link status
Why it's wrong here
The connection is up, so the physical link is fine.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a working BGP session guarantees end-to-end connectivity, but BGP only ensures the routing protocol is exchanging prefixes; the VPC route table must still have the propagated routes or a static route to direct traffic to the virtual private gateway.
Detailed technical explanation
How to think about this question
When using Direct Connect, the virtual private gateway (VGW) must be associated with the VPC, and route propagation from the VGW must be enabled in the VPC route tables. Even with BGP established, if the VPC route table does not have a route pointing to the VGW for the on-premises CIDR (either via propagation or a static route), traffic from the VPC will not be forwarded to the Direct Connect link. Additionally, ensure that the allowed prefixes in the Direct Connect virtual interface match the on-premises CIDR being advertised.
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.
TExam Day Tips
→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.
