Wait, does it really need to be a default gateway?

Definitely needs to receive forwarding lookups!

I vaguely remember that using a Layer 3 underlay network is important for routing, but I’m not confident if that’s the main requirement for the NGFW.

I feel like the forwarding lookups from the network controller are crucial for the NGFW's operation in ACI, but I need to double-check that.

I think I practiced a question where the NGFW was mentioned as a default gateway, but I can't recall if that's the right answer here.

I remember something about the NGFW needing to integrate closely with ACI, but I'm not sure if it has to be a device cluster.

Ah, I see. The NGFW must use a Layer 3 underlay network to properly integrate with the Cisco ACI environment. Good to know!

I'm a bit confused on this one. Does the NGFW need to be the default gateway or receive forwarding lookups from the network controller? I'll have to review the options carefully.

I've got this! The NGFW needs to be a member of a device cluster to secure the ACI traffic. Easy peasy.

Okay, let's see. I think the key is understanding how the NGFW needs to be integrated with the ACI network. I'll need to review the configuration requirements.

Hmm, this seems like a tricky one. I'll need to think carefully about the relationship between the Palo Alto NGFW and the Cisco ACI environment.

Option D sounds like a lot of work. Why would I want to configure a Layer 3 underlay network when I can just let the NGFW handle everything?

Come on, folks, it's not rocket science. The NGFW needs to be integrated with the network controller to do its job properly. Duh!

Option A seems the most logical choice to me. Deploying the NGFW as a member of a device cluster would provide high availability and redundancy, which is crucial for securing critical network traffic.
