Upgrading Your Skills to MCSA: Windows Server 2016 — Question 75

You have two servers named Server1 and Server2. A firewall exists between Server1 and Server2.
Both servers run Windows Server Update Services (WSUS). Server1 downloads updates from Microsoft update.
Server2 must synchronize updates from Server1.
Which port should to open on the firewall?

Answer options

• A. 80
• B. 443
• C. 3389
• D. 8530

Correct answer: D

Explanation

The correct port to open for WSUS synchronization between Server1 and Server2 is port 8530, which is used for WSUS communication. Port 80 is used for HTTP traffic, while port 443 is for HTTPS, neither of which is specific to WSUS synchronization. Port 3389 is used for Remote Desktop Protocol (RDP) and is not relevant in this scenario.
