Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Cisco Secure Firewall AWS Lambda scripts
Why this is correct
AWS Lambda scripts are officially provided by Cisco to automate route table updates during failover in AWS.
✗
Cisco Adaptive Security Virtual Appliance (ASAv) state synchronization protocol
Why it's wrong here
ASAv state sync does not handle AWS route table manipulations natively.
✗
BGP peering directly with the AWS Internet Gateway
Why it's wrong here
AWS Internet Gateways do not support dynamic BGP peering directly with virtual appliances.
✗
Gratuitous ARP via the transit gateway
Why it's wrong here
Transit Gateways do not natively process standard gratuitous ARP for cross-AZ failover in the same manner as bare-metal deployments.
