Microsoft Azure Administrator (legacy) — Question 13

You have a public load balancer that balances ports 80 and 443 across three virtual machines.
You need to direct all the Remote Desktop Protocol (RDP) connections to VM3 only.
What should you configure?

Answer options

• A. an inbound NAT rule
• B. a load balancing rule
• C. a new public load balancer for VM3
• D. a frontend IP configuration

Correct answer: A

Explanation

The correct answer is A, an inbound NAT rule, as it allows traffic on a specific port (like RDP) to be redirected to a designated VM, in this case, VM3. The other options do not provide the necessary specificity to direct RDP traffic solely to VM3; a load balancing rule (B) would distribute the connections, a new load balancer (C) is unnecessary, and a frontend IP configuration (D) does not control traffic routing.
