You have an Azure virtual machine named VM1. The network interface for VM1 is configured as shown in the exhibit. (Click the Exhibit tab.) 

You deploy a web server on VM1, and then create a secure website that is accessible by using the HTTPS protocol. VM1 is used as a web server only. You need to ensure that users can connect to the website from the Internet. What should you do? 

Answer options:

A. Modify the protocol of Rule4
B. Delete Rule1
C. For Rule5, change the Action to Allow and change the priority to 401
D. Create a new inbound rule that allows TCP protocol 443 and configure the rule to have a priority of 501.

C

HTTPS uses port 443. Rule2, with priority 500, denies HTTPS traffic. Rule5, with priority changed from 2000 to 401, would allow HTTPS traffic. Note: Priority is a number between 100 and 4096. Rules are processed in priority order, with lower numbers processed before higher numbers, because lower numbers have higher priority. Once traffic matches a rule, processing stops. 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. Note: There are several versions of this question in the exam. The question has two possible correct answers: 1. Change the priority of Rule3 to 450. 2. For Rule5, change the Action to Allow and change the priority to 401. Other incorrect answer options you may see on the exam include the following: ✑ Modify the action of Rule1. ✑ Change the priority of Rule6 to 100. ✑ For Rule4, change the protocol from UDP to Any.
