Exam N10-008 topic 1 question 385 discussion

I was expecting this to be a port security answer...

This technician sucks lol

The fact that the issue is affecting different users on different days suggests that it’s not a problem with individual user settings or hardware, but rather with the network configuration itself. Rebooting the PCs would not resolve this issue, as the problem lies with the network, not the individual machines.

Incorrect firewall settings can affect a portion of port security that would block network segments, or individuals in a blacklist. Inappropriate VLAN assignment would not allow users to certain departments in the network & not block them from the entire network. Because this is multiple users, all sharing the same sudden hardware failure is unlikely unless they had old parts no longer supported. A Content Addressable Memory (CAM) is an attack on a system memory construct, the attacker connects to a single, or multiple switch ports & then to a single, or multiple switch ports & then runs a tool that mimics the existence of thousands of random MAC addresses on those switch ports. This will cause the CAM table to be full & can be utilized to fill the capacity of the DHCP server, but many more users would be affected, & there would be major slow down to the whole network.

Given the description in the scenario, an overloaded CAM table in the switch remains the most likely cause of the issue. It is a plausible explanation for why specific users experience connectivity problems, as the CAM table may not be able to keep up with the frequent changes or traffic patterns in the network.

Since D is not listed in the CompTIA objectives nor in any of the study materials, the more obvious one is E. They're able to reboot the PC and access the PC system ( I believe there was a typo in this question because they originally cannot access the network not the system) so C is out. DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to users out of a scope that the admin configured for the office according to this scenario, if there's a DHCP failure or scope exhaustion, users wont be able to get an IP address (other than APIPA) in order to access the network.

There are a lot of DHCP questions on this and I've noticed almost everytime it is an option it is the answer.

based on Chat GPT Based on the information provided, it is unlikely that the CAM table is the problem. The CAM table is used in switches to map MAC addresses to switch ports and is typically updated dynamically as devices communicate on the network. If there were a problem with the CAM table, it would typically result in connectivity issues for all users connected to the affected switch, not just a few.

E is CORRECT

. Overloaded CAM table in switch is the most likely scenario. The fact that the issue is occurring with different users each day suggests that the problem is not with the individual PCs or their configurations. Additionally, rebooting the PCs did not resolve the issue, which further supports this idea. The symptoms described could be caused by an overloaded CAM (Content Addressable Memory) table in the switch. The CAM table is used to map MAC addresses to switch ports, allowing the switch to forward frames to the correct destination. If the table becomes full, new MAC addresses cannot be learned, and frames may be dropped, resulting in connectivity issues. Incorrect firewall settings, inappropriate VLAN assignment, hardware failure, and DHCP scope exhaustion are also possible causes of network connectivity issues, but they are less likely to be the cause of the described symptoms in this particular scenario.
