Topic #: 1
[All PSE-SoftwareFirewall Questions]

Which two criteria are required to deploy VM-Series firewalls in high availability (HA)? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

Wait, is asymmetric routing really necessary? I thought it wasn't.

I thought you could use different hosts for HA, but I guess not!

I’m pretty sure both firewalls need to have the same licenses, but I’m torn between the hypervisor type and deployment on different hosts for the second option.

I practiced a question like this, and I feel like asymmetric routing was mentioned, but I can't remember if it's a must-have for HA setups.

I remember something about needing to deploy on the same type of hypervisor, but I can't recall if that's a strict requirement for HA.

I think one of the criteria is definitely the assignment of identical licenses and subscriptions, but I'm not sure about the second one.

This is a good test of my knowledge on HA deployment. I'm confident I can narrow it down to the two correct criteria.

I'm a bit confused on the asymmetric routing option. Does that mean the firewalls need to be on different networks? I'll have to double-check that.
