CompTIA A+ Core 2 (220-1102) — Question 509

A systems administrator needs to access a hypervisor that went offline. After doing a port scan, the administrator notices that company policy is blocking the RDP default port. Which of the following ports should the administrator use to access the machine?

Answer options

• A. 22
• B. 23
• C. 80
• D. 3090

Correct answer: A

Explanation

The correct answer is A, port 22, which is commonly used for SSH access. Port 23 is associated with Telnet and is less secure, port 80 is designated for HTTP traffic, and port 3090 does not have a standard use for remote desktop access, making them unsuitable for the intended purpose.
