The correct answer is to use BGP community tags on the Direct Connect gateway to influence routing. This works because BGP communities allow you to attach specific tags to routes advertised over a Direct Connect virtual interface (VIF), enabling the Direct Connect gateway to prioritize or steer traffic to a particular VIF based on those tags. For security compliance, you can tag routes from a specific VPC with a community value that tells the on-premises router to prefer a designated VIF, effectively controlling the path without complex policy-based routing. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this concept tests your understanding of how to steer traffic to specific VIF using BGP communities, often appearing as a scenario where you must choose between VIF-level policies and gateway-level tagging. A common trap is assuming you can manipulate routing directly on the VGW or VIF, but only the Direct Connect gateway supports the community-based path selection. Memory tip: think of BGP communities as “postage stamps” on routes—they tell the network where to deliver the traffic, not how to build the envelope.
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 has a Direct Connect connection with multiple virtual interfaces (VIFs). They want to ensure that traffic from on-premises to a specific VPC uses a specific VIF for security compliance. The VPC is associated with a virtual private gateway. Which configuration ensures this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use BGP community tags on the Direct Connect gateway to influence routing
To steer traffic to a specific VIF, you can use BGP communities on the Direct Connect gateway. Option C is correct. Options A, B, and D do not provide the necessary granularity.
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.
✗
Configure the on-premises router to use a different BGP ASN for each VIF
Why it's wrong here
BGP ASN does not control path selection for incoming traffic.
✓
Use BGP community tags on the Direct Connect gateway to influence routing
Why this is correct
BGP communities allow you to tag routes and influence path selection.

Read the scenario before looking for a memorised answer.
✗
Assign different IP addresses to each VIF and add static routes
Why it's wrong here
Static routes can be used but are less flexible and do not leverage BGP.
✗
Create a separate virtual private gateway for each VIF
Why it's wrong here
This would require separate VPCs, not a single VPC.
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.

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.
