ANS-C01 Network Management and Operations Practice Question
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 choices
Why each option matters
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 from on-premises to a specific VPC over a specific VIF, you can use BGP community tags on the Direct Connect gateway. This allows you to influence routing decisions by tagging routes. Option A does not achieve traffic steering because different ASNs are not used for that purpose. Option C (static routes) would not provide the flexibility and dynamic routing capabilities needed. Option D is unnecessary and does not solve the requirement. Therefore, option B is correct.
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.
- ✗
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.
