300-710 SNCF Deployment Practice Question
An engineer is deploying a Cisco Secure Firewall Threat Defense Virtual (FTDv) instance in an Amazon Web Services (AWS) VPC. The deployment requires the FTDv to inspect traffic crossing between public and private subnets. Which AWS architectural construct is mandatory for routing traffic through the FTDv instance?
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
✓
Custom AWS Route Tables associated with the subnets, pointing traffic destined outside the VPC to the FTDv data interface ENI.
In public cloud deployments like AWS, routing traffic through a firewall appliance requires updating AWS Route Tables to point default or specific subnet traffic to the Elastic Network Interface (ENI) of the firewall's internal/external interfaces.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Custom AWS Route Tables associated with the subnets, pointing traffic destined outside the VPC to the FTDv data interface ENI.
Why this is correct
AWS route tables must be modified to point traffic to the firewall instance's Elastic Network Interface (ENI) to ensure traffic flows through the virtual firewall.
- ✗
Cisco TrustSec Security Group Tags (SGTs) applied to AWS security groups.
Why it's wrong here
SGTs are for policy enforcement, not packet steering in AWS route tables.
- ✗
AWS Transit Gateway with static BGP peering enabled to the FTDv management interface.
Why it's wrong here
Transit Gateway is optional; route tables are the fundamental mechanism for steering traffic to an ENI.
- ✗
Physical bypass NICs installed in the AWS hypervisor layer.
Why it's wrong here
AWS is a public cloud; physical NICs cannot be manipulated by users.
