Given the situation, checking the DHCP server is the most logical next step.

Selected Answer: D

its D since the issue affects multiple computers and none of them have static Ip addresses. it is possible that the DHCP server is not assigning IP addresses correctly which can lead to connectivity issues.

id check the AP point first then DHCP

None of the computers has assigned a static IP and two of them can communicate - it means that DHCP is in use and is working. We can't assume that the rest of them are wireless, as they mentioned two wired computers. It is non sense to check each NIC in this situation. The answer must be C - the switch can be failing or it may have disconnected/faulty jacks/cables. This should be the next thing to check. Always check the physical connection first according to the CompTIA troubleshooting methodology.

Amendment - We can't assume that working computers use a DHCP server, but if they are connected they either must use static IP or the DHCP server. Either way, the PHYSICAL connection must be checked first.

I am guessing only the ones who got a dynamic IP address are having issues because it changes unlike the static addresses. So they rely on the DHCP server to get a IP. Are only wired connections able to use static addressing?

Double checked in different sources - it's D: DHCP Server .

Several computers are having network connectivity issues... None of the computers assigned static IP's have connectivity issues. The question does not say, "Several computers are having wireless network connectivity issues". And, two of the computers are connected hard-wire with no issues.

A - Check the closest Access Point -- the wired computers can connect but the wireless computers cannot. We don't know if the wired computers have static or dynamic (DHCP) IP addresses, so we don't know if this is a DHCP problem. But we do know that the wireless computers connect to the network via an Access Point, so we should first check there first.

Don't forget. The nearest access point are wired and would mean (in my opinion) that these are simply connections that we check to make sure that they are connecting properly. They might not actually solve the issue of several computers having trouble connecting to the DHCP server, which is what I argue is the real point of this answer. Unless I am wrong.

Answer A is the correct one because is the simplest solution to do NEXT, and the definition of access point in the CompTIA manual is that an access point is a device that provides connectivity between wired and wireless networks (page 1164). I think there's no such thing as a wired access point (they're called hubs, switches, etc...).

But is it a 'wireless' Access Point? For all we know, the access point for your chosen answer could be wired instead and that wouldn't help us exactly, now would it? Anyways, I think the answer of checking the DHCP server is more clearer than what you suggest.

What other kind of access point do you expect to find. For a wired connection you plug into a switch, whereas a Wireless Access Point gives you wireless access to a wired network. You'll need to know the differences between APs hubs and switches when you sit the exam. Not a lot of info in this one again but we know 1. Wired connections are working normally (implies the DHCP server is working but can't communicate to some machines, or there is an IP conflict) and 2. No machines experiencing issues have a static IP (implying the issue isn't an IP conflict). It doesn't explicitly mention that the other machines are wireless but i think this is implied in the wording. So we know DHCP CAN hand out IP addresses but there's a connection problem with ONLY wireless devices. First step would be to find the closest AP (Is it in range, is it working, did a cleaner unplug it or something silly like that over night)

Why is the answer DHCP server and not access point?

I think the key to this question is this sentence: "The technician verifies that none of the computers having issues have been assigned a static IP". This is a very strong statement. This means that all the computers that are having trouble to connect to the network are using a dynamic IP addresses. The DHCP server is in charge of this task. If it is not working fine, then the computers won't be able to connect.

are we supposed to assume from this wording that the wired connections are static?

But if the problem is DHCP also the wired PC should have connectivity issues

you don't know if the wired are static or not, all you need to know is that static IP is not having issue but rest are. all the mumbo jumbo in the beginning is useless text. Just like in real life where a customer will try to describe their problem to you. have to know how to pick up the key components
