CompTIA Cloud+ (CV1-003) — Question 53

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 because RDP uses TCP port 3389 for connections, and if this port is blocked, users will encounter a timeout error. Options A, B, and C address other potential issues but do not directly resolve connectivity problems associated with RDP.
