Microsoft Azure Administrator Associate AZ-104 Practice Question
An administrator is unable to connect to a Linux server hosted in Azure over port 22 from the internet. The security group associated with the server's subnet includes an inbound rule with priority 200 that permits traffic on TCP port 22. There is also an inbound rule with priority 100 that blocks all inbound traffic. What is causing the connectivity issue?
The inbound rule for port 22 is using the wrong protocol type
The deny rule with a higher priority is preventing access before the allow rule is processed
Port 22 is closed on the server's operating system firewall
The server's network interface is not associated with the correct security group
In Azure, security rules are evaluated in order of their priority values, starting from the lowest number. The rule with priority 100 denies all inbound traffic and is processed before the rule with priority 200 that allows port 22. This means the deny rule takes effect first, blocking the connection attempt before the allow rule is considered. To resolve the issue, the allow rule for port 22 should have a lower priority number than the deny rule, so it is evaluated first.
