Microsoft Azure Administrator (AZ104) Practice Exam

When IP forwarding is enabled on a virtual machine, it allows that VM to act as a gateway where it can forward traffic to and from other resources. If VM3 is turned off, it will not actively participate in any routing or traffic forwarding, but the state of VM3 does not inherently block connections to or from other VMs unless specific network security rules or conditions are enforced.

In this case, if VM3 has IP forwarding enabled and is powered down, it does not actively impede the ability of VM2 to connect to VM1. VM2 can still initiate a connection to VM1 independently, assuming no other network configurations or security rules restrict this traffic. There are no inherent dependencies between VM2 and VM3 that would prevent VM2 from communicating with VM1 just because VM3 is powered off.

The other possible outcomes would imply that the state of VM3 directly influences the connections between VM1 and VM2 in a restrictive manner, which is not the case here. The configuration of networking and VM forwarding features does not introduce blocking effects simply due to a powered-off state of any VM.
