Correct answer & explanation
✓
Enable Bidirectional Forwarding Detection (BFD) on the virtual interfaces
Enabling Bidirectional Forwarding Detection (BFD) on the virtual interfaces allows rapid detection of connectivity failures, which can help isolate whether the issue is on the AWS side or the customer side. Option A is wrong because increasing bandwidth may not resolve intermittent issues caused by routing problems. Option C is wrong because tagging does not impact network performance. Option D is wrong because changing the private ASN does not affect performance.
