Which protocol is used for communicating between VM-Series firewalls and a gateway load balancer in Amazon Web Services (AWS)?

Show Suggested Answer Hide Answer
Suggested Answer: D

App-ID is the component that can provide application-based segmentation and prevent lateral threat movement. Application-based segmentation is a method of dividing the network into smaller segments or zones based on application or workload characteristics, such as function, dependency, owner, or security posture. Lateral threat movement is a technique used by attackers to move across the network from one compromised host to another, looking for sensitive data or assets. App-ID is a feature that identifies and classifies applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. App-ID can provide application-based segmentation and prevent lateral threat movement by applying granular security policies based on application information to each segment or connection, blocking unauthorized access or data exfiltration. DNS Security, NAT, and URL Filtering are not components that can provide application-based segmentation and prevent lateral threat movement, but they are related features that can enhance security and visibility.

VRLAN? That's not even a real thing. Did they get their networking protocols mixed up with their kitchen appliances?

No, VRLAN is not a real protocol. It's GRE that is used for communicating between VM-Series firewalls and a gateway load balancer in AWS.

Ooh, a trick question! I bet it's not even one of those options. AWS loves to keep us on our toes.

VMLAN? Really? That sounds made up. I'll have to go with Geneve on this one.

Hmm, I'm not sure. GRE seems like a common tunneling protocol, but I'm not confident it's the right choice here.

I think the answer is Geneve, since that's the AWS-recommended protocol for connecting VMs to load balancers.
