Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Direct Connect gateway is not associated with the virtual private gateway or route propagation is not enabled
Even though the Direct Connect private virtual interface is in the 'available' state and the BGP session is up, the on-premises network cannot reach VPC resources because the Direct Connect gateway is not associated with the virtual private gateway or route propagation is not enabled. This association is necessary for route exchange between the VPC and on-premises network. Option A is incorrect because the BGP ASN being private is allowed; the BGP session is up indicating ASN is valid. Option B is incorrect because the VLAN ID is irrelevant once the virtual interface is available and BGP is up. Option D is incorrect because the BGP session is established.
