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
✓
Verify that the BGP ASN configured on the customer router matches the one provided by AWS.
Common BGP issues include incorrect BGP ASN, incorrect peer IP addresses, missing authentication, and firewall rules blocking TCP port 179. Verifying these settings on both sides is key.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Verify that the BGP ASN configured on the customer router matches the one provided by AWS.
Why this is correct
Mismatched ASN prevents BGP session establishment.
- ✗
Increase the MTU on the customer router interface.
Why it's wrong here
MTU issues can cause problems but are not typical for BGP session establishment.
- ✗
Ensure that the virtual interface is in the 'available' state.
Why it's wrong here
The VIF state is important, but it's not a direct BGP troubleshooting step.
- ✓
Verify that the peer IP addresses on both sides are correct and reachable.
Why this is correct
Incorrect IP addresses cause session failure.
- ✗
Check that the Direct Connect connection is in the 'available' state.
Why it's wrong here
The connection state is needed, but not specifically for BGP establishment.
