Actual exam question for CompTIA's XK0-005 exam
Question #: 26
Topic #: 3
[All XK0-005 Questions]

Users are experiencing high latency when accessing a web application served by a Linux machine. A systems administrator checks the network interface counters and sees the following:

Which of the following is the most probable cause of the observed latency?

Show Suggested Answer Hide Answer
Suggested Answer: B

The high number of errors and dropped packets in the output of the network interface counters indicate a connection problem on the network interface.

I doubt it’s a disconnection issue; that’s rare.

The gateway being unreachable seems like a possible cause, but I wonder if there are other factors we should consider before jumping to that conclusion.

I feel like we covered something about IP addresses in class, but I'm not convinced that having no IP assigned would just cause latency.

I'm not entirely sure, but I think a connection problem on the network interface could definitely cause latency. It sounds familiar from our practice questions.

I remember we discussed how a disconnected network interface would usually lead to no connectivity at all, so that can't be the issue here.

Based on the information provided, the most likely cause seems to be a connection problem on the network interface. I'll select that option and move on to the next question.

I'm a little confused on the difference between confidentiality and integrity here. Wouldn't the consultant also want to protect the integrity of the reports, since they're being handled by temporary workers? I'll have to review those concepts again.

The key here is understanding how expression modes work. If you add multiple child rules, the expression mode controls the application of those rules.

Okay, I've got this. We need to predict a numerical value (sea level) over time, so regression is definitely the way to go. Option B is the correct answer.

I think it could also relate to objectivity, but I'm not completely certain. We should remain impartial, but I need to double-check the definitions.

I don't think so, if the gateway was unreachable, we would see errors related to routing, not just on the network interface.

Haha, yeah, the old 'blame the hardware' trick. Classic IT exam question. But in this case, I think you guys are right - B is the most likely culprit. Though I have to say, if I was the sysadmin, I'd be double-checking all the cables and switch ports first before jumping to any conclusions.

Hmm, good point. The gateway being unreachable could definitely be a factor. But I still think the connection problem is the most likely explanation. It's like the network interface is trying to play traffic cop, but just can't keep up with all the cars (or packets) trying to get through.

I agree with you both. D - the gateway being unreachable - is also a possibility, but the network interface stats point more towards a local connection problem. Though I have to admit, I'm a little surprised they didn't include an option about high CPU or memory usage on the server. That can also cause latency, you know.

I don't know, guys. What if the gateway is just MIA? Option D seems plausible to me. I mean, if the gateway's not responding, that could definitely cause some major latency issues.

You know, I was just thinking the same thing. The RX errors and collisions are a dead giveaway that there's something wrong with the network connection. It's probably not a disconnect or IP address issue, since those would show different metrics.

Hmm, this is a tricky one. The high latency could be due to a few different issues, but I'm leaning towards B - a connection problem on the network interface. Those counter values seem to indicate some kind of network congestion or errors.

Yeah, the collision count is definitely interesting. Maybe the network interface is just a bit too crowded, like a busy highway during rush hour. But I still think option B is the best answer based on the information provided.

Collisions, huh? Sounds like this network interface is having a bit of a 'collision course' with high latency! (chuckles) But in all seriousness, I think you two are on the right track. Connection problem seems like the most likely culprit here.
