Which Port Should Be Opened for Remote Server Access?
A technician is troubleshooting servers with high CPU usage. While trying to connect, the technician needs to open a port for remote access. Which of the following ports should the technician open?

100% of anonymous learners picked answer D. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
Tests recognition of specialized remote administration ports, with the common trap being the selection of familiar web security ports instead of actual desktop control protocols.
This question evaluates knowledge of standard network ports used for remote server management. Community consensus and recent exam reports confirm port 5900 as the correct choice for enabling VNC-based remote desktop access.
Option A (443) is frequently chosen due to its widespread use for secure web administration, but it only encrypts HTTP traffic rather than providing full graphical remote desktop control.

Why the Answer Is Correct
Port 5900 is the standard default port for Virtual Network Computing (VNC), a remote desktop protocol that grants full graphical control over a server. Opening this port allows technicians to directly interact with the server environment, making it ideal for troubleshooting resource issues like high CPU usage.Why the Other Options Are Wrong
Port 443 handles encrypted HTTPS web traffic, while 8080 serves as an alternative HTTP port commonly used for web proxies or development servers. Neither provides native remote desktop capabilities required for full system control. Port 3321 corresponds to vnsstr, a niche utility that lacks enterprise adoption for standard server administration.Community Comment Notes
Multiple candidates verified this exact question appeared on recent N10-008 exams, strongly validating port 5900 as the expected answer. Users highlighted that although VNC is occasionally overlooked in official objectives, CompTIA frequently includes legacy or alternative remote access ports to test practical knowledge. The detailed port breakdown provided by top-voted comments effectively clarified why web ports are incorrect distractors.Official Reference
Exam Strategy
Memorize both mainstream remote access protocols (SSH, RDP) and secondary alternatives like VNC, as CompTIA often tests niche ports that fall outside the primary syllabus. When facing port questions, immediately eliminate web traffic options to isolate true remote administration services.
