CompTIA Exam N10-008 Topic 3 Question 56 Discussion

Actual exam question for CompTIA's N10-008 exam
Question #: 56
Topic #: 3
[All N10-008 Questions]

An office area contains two PoE-enabled WAPs. After the area was remodeled, new cable uplinks were installed in the ceiling above the fluorescent lights. However, after the WAPs were reconnected, users reported slowness and application errors. An intern reviewed the network and discovered a lot of CRC errors. A network engineer reviewed the intern's work and realized UTP cabling was used. Which of the following is the MOST likely cause of the CRC errors?

Show Suggested Answer Hide Answer
Suggested Answer: C

The servers can communicate with each other but not the internet, indicating local network connectivity is fine. The distribution switch's VLAN and IP configuration are correct, and the engineer can reach the core router, suggesting the issue is not with the switch or the router. The most likely cause is that the servers do not have a default gateway configured, which is necessary for traffic to leave the local network and reach the internet.

Did the engineer try turning it off and on again? Just kidding, but seriously, C sounds like the most likely culprit here. Those servers need a gateway!

A: Definitely, without a default gateway, they can't connect outside of their own network.

A routing loop? Nah, the servers can reach themselves. I'm thinking C is the way to go - no default gateway set up for the servers.

Yeah, setting up the default gateway on the servers should solve the issue.

Maybe the engineer should double-check the server configurations for the default gateway.

But the engineer can reach the core router, so it's not a routing loop issue.

I agree, without a default gateway, the servers won't be able to reach the internet.

It's possible, but I think the default gateway issue is more likely based on the information provided.

But could it also be because of an improper Layer 1 connection between the router and the ISP modem?

Hmm, the core router is accessible, so it's not a Layer 1 issue. I'd go with C - the servers need to be configured with a default gateway.

The subnet mask seems off, the servers can't reach the internet. Probably option B is the right answer here.

Yeah, that makes sense. The servers need the correct subnet mask to reach the internet.
