Wait, can you really use FRA for filtering? That’s new to me!

I think B is better, VPNs add more security.

Option A sounds solid, VPC peering is a good choice!

I recall that using firewall rules is a common practice for controlling traffic, but I’m not certain if that’s enough for our requirements in this scenario.

I’m a bit confused about the difference between the Host Project and Service Project in this context. I feel like I might mix them up during the exam.

I remember that shared VPCs are important for managing resources across departments, but I'm not sure if we need two separate shared VPCs or just one.

I think option A sounds familiar because it mentions VPC peering, which we practiced in a similar question about inter-departmental communication.

This question seems straightforward, but I want to make sure I understand the key differences between Microsoft 365 and Azure Virtual Desktop before answering.

Hmm, I'm not sure about this one. A read-only lock could work, but I'm not confident that would give us the level of control we need over the regions. Let me think this through a bit more.

Okay, let me see. If there are 5 hardware virtualized guests running, then I would expect to see 5 QEMU-DM processes, one for each guest. That's my best guess.
