Your company has two cloud services named CS01 and CS02. You create a virtual machine (VM) in CS02
named Accounts.
You need to ensure that users in CS01 can access the Accounts VM by using port 8080.
What should you do?

A.
Create a firewall rule.

B.
Configure load balancing.

C.
Configure port redirection.

D.
Configure port forwarding.

E.
Create an end point.

Explanation:
All virtual machines that you create in Azure can automatically communicate using a private network channel
with other virtual machines in the same cloud service or virtual network. However, other resources on the
Internet or other virtual networks require endpoints to handle the inbound network traffic to the virtual machine.
