Question #: 49
Topic #: 1

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?

A443

B3321

C8080

D5900

Show Suggested Answer

Suggested Answer: D

Port 5900 is the default port used by Virtual Network Computing (VNC), a graphical desktop-sharing system that allows remote access to another computer's screen, keyboard and mouse1. VNC is one of the tools that can be used for remote troubleshooting of servers with high CPU usage, as it enables the technician to see the server's desktop and perform actions on it. Port 5900 is also one of the ports listed in the CompTIA Network+ N10-008 exam objectives under the section '1.4 Given a scenario, use appropriate software tools to troubleshoot connectivity issues'2.

The other ports are not commonly used for remote access. Port 443 is used for Hypertext Transfer Protocol Secure (HTTPS), a secure version of HTTP that encrypts the communication between a web browser and a web server3. Port 3321 is used for Telepathy Broker Service, a service that provides communication between applications and telephony devices4. Port 8080 is used for HTTP Alternate, an alternative port for HTTP that is often used by web servers for testing or proxy purposes5.

Port 8080? Really? That's a bit of a stretch, don't you think? If I was the technician, I'd just go with the tried and true 5900 and be done with it.

Haha, you all sound like you're trying to hack into the servers or something. Just kidding, but seriously, I think port 3321 is the way to go. It's not a common port, so it might be more secure, and it's not likely to be in use already.

You guys are overthinking this. Why not just go with port 8080? It's a common alternative to the standard HTTP port 80, and it's often used for web-based management tools. Seems like a simple solution to me.

You guys are all overthinking this. Why not just go with port 8080? It's a common port used for web servers, so it's probably not being used for anything else on the servers.

Really? I was thinking port 443 would be the way to go. That's the standard port for HTTPS, and it's often used for secure remote access. Plus, it's usually allowed through firewalls, so it might be the most reliable option.

I see what you mean, Rene, but in this case, the technician is just trying to troubleshoot the servers, not necessarily establish a long-term remote connection. Port 5900 is fine for that purpose.

Hmm, this is a tricky one. We need to open a port for remote access to troubleshoot the servers with high CPU usage. I'm thinking port 5900 might be the best option since that's usually used for remote desktop protocols like VNC.

Hmm, I'm not so sure about that. Wouldn't it be better to use a more secure port like 443, which is used for HTTPS? That way, the remote connection would be encrypted.

I agree with Daniel. Port 5900 is the obvious choice here. It's the standard port for remote desktop access, which is exactly what the technician needs to troubleshoot the high CPU usage on the servers.

This question seems pretty straightforward to me. If we need to open a port for remote access, the logical choice would be port 5900, which is commonly used for VNC (Virtual Network Computing) connections.
