Exam AZ-300 topic 2 question 39 discussion

Actual exam question from Microsoft's AZ-300

Question #: 39
Topic #: 2

You have an Azure subscription named Subscription1. Subscription1 contains a virtual machine named VM1. You have a computer Computer1 that runs Windows
10. Computer1 is connected to the Internet.
You add a network interface named Interface1 to VM1 as shown in the exhibit. (Click the Exhibit tab.)

From Computer1, you attempt to connect to VM1 by using Remote Desktop, but the connection fails.
You need to establish a Remote Desktop connection to VM1.
What should you do first?

A. Attach a network interface
B. Start VM1
C. Delete the DenyAllOutBound outbound port rule
D. Delete the DenyAllInBound inbound port rule

Show Suggested Answer

Suggested Answer: B 🗳️
Incorrect Answers:
A: The network interface has already been added to VM.
C: The Outbound rules are fine.
D: The inbound rules are fine. Port 3389 is used for Remote Desktop.
Note: Rules are processed in priority order, with lower numbers processed before higher numbers, because lower numbers have higher priority. Processing stops once traffic matches a rule. As a result, any rules that exist with lower priorities (higher numbers) that have the same attributes as rules with higher priorities are not processed.

The correct answer is: B. Start VM1 Explanation The machine is in the stopped status. This is the case, because the public IP address is not assigned to the virtual machine instead it is showing IP2. That is why you can’t connect to the virtual machine.

Maybe other way to seeing it is: D: InBound isn’t in the question, C: the rules is overwritten by Vnet and Internet OutBound, A: The VM has a NIC, SO the only option that makes sense is B.
