CompTIA Cloud+ (CV0-003) — Question 375

A cloud administrator has finished setting up an application that will use RDP to connect. During testing, users experience a connection timeout error. Which of the following will MOST likely solve the issue?

Answer options

• A. Checking user passwords
• B. Configuring QoS rules
• C. Enforcing TLS authentication
• D. Opening TCP port 3389

Correct answer: D

Explanation

The correct answer is D, as opening TCP port 3389 is necessary for RDP connections to function. Without this port being open, the connection requests will be blocked, leading to timeouts. The other options do not directly address the network connectivity needed for RDP.
