DCHP scope exhaustion is not the answer because the user already holds an IP. The next most likely answer is channel overlap

Sorry that is incorrect. Study up on how DHCP exhaustion works, and you'll understand why. Cannel overlap can cause interference in network performance, but it wouldn't cause for the laptop to lose connection to the network.

Incorrect because dhcp servers have lease times for ips. what more than likely happened was the laptops lease was expired and was kicked off.

You are WRONG. "The next day, a technician was able to connect the TV to the Wi-Fi, but a bank laptop lost network access at the same time." - you think the DHCP lease of the laptop miraculously expired the exact moment the TV connected to the Wi-Fi? Nope. Channel overlapped is the correct answer.

Study up on DHCP exhaustion and DHCP pool.

I deal with DHCP all the time at my job, and I can tell you that you have no clue how it works. When an IP is assigned it stays assigned until it expires and if the machine doesn't ask for renewal. Which means, if the computer is connected, that IP will never be assigned to something else until the lease expires, the pool is exhausted AND the computer isn't online to ask for a renew. To top it off, it doesn't even wait until the TTL is completely expired, it starts asking for renewal way before that, which means only new devices will not get an IP, until some other one effectively stops asking for renewal. The question states that the computer lost network access at the SAME TIME the TV was connected, and I'm telling you, this is not how DHCP exhaustion works. The only sensible answer is D, even though it's still pretty idiotic.

In this scenario, when the smart TV was connected to the Wi-Fi, it was likely assigned the last available IP address in the DHCP scope. When the laptop attempted to connect to the Wi-Fi, there were no remaining IP addresses to assign, so the laptop could not connect to the network.

Channel Overlap: Channel overlap could cause interference and connectivity issues, but it would typically affect multiple devices rather than just one gaining access while another loses it. CompTIA wants you to know that the laptop lost its lease and the tv got it instead now the laptop has the same problem as the TV had. Using this information you can put 2 and 2 together and see that it is DHCP scope exhaustion.

The standard DHCP lease time is 24 hours. Since we are connecting devices "the next day" it would be feasible that the TV has the last IP available.

Selected Answer: A

The most likely cause of the smart TV being unable to connect to the Wi-Fi initially, followed by the bank laptop losing network access when the TV was connected, is DHCP scope exhaustion. When the DHCP scope is exhausted, new devices trying to connect to the network won't receive an IP address, leading to connection issues. This scenario is consistent with the symptoms described, where the TV couldn't connect initially, but the technician was able to connect it the next day, possibly after some IP addresses were released from the DHCP pool. However, when the TV obtained an IP address, it might have taken the last available one, leaving no addresses for the bank laptop when it attempted to renew its lease, resulting in the loss of network access.

I mean channel overlap only occures between APs. They only installed a TV in this question, how should this produce channel overlap? It has to be a DHCP scope problem.

hen the DHCP server has exhausted the pool of IP addresses it can assign, any new device trying to connect to the network will be unable to obtain an IP address, while devices that are already connected may continue to operate until they need to renew their IP lease.

It's definitely DHCP exhaustion. Channel overlapping would not result in immediate loss of connectivity

A. DHCP scope exhaustion - DHCP server has run out of available IP addresses to assign to clients on the network. The day when the TV couldn't connect there weren't any IP addresses available. The following day the TV was able to get an IP address from the DHCP. But the laptop couldn't because the DHCP ran out of IP addresses again(like the day before).

Its scope exhaustion - when the laptop is connected first in the example the tv cannot connect - and when the tv is connected first the laptop cannot pull an ip this is because there are no more ips that can be pulled. its have a lease time and a limited amount of slots.

It's channel overlap. It's unlikely that the DHCP lease of the already connected device immediately expires the moment you connect another device to the wifi, so it can't be a DHCP cope exhaustion. Other answers make no sense. Guess what, chatgpt isn't always right, who woulda thunk? Goons use your brain.

C. Hidden SSID A hidden SSID (Service Set Identifier) is a Wi-Fi network that does not broadcast its name (SSID) publicly. When connecting to a hidden SSID, the client device needs to know the SSID in advance, and sometimes, this can cause connectivity issues, especially if not configured properly on all devices.

looked this up on google yall you gotta put some effort into the thought and not just jump the gun! "What happens when DHCP lease expires? When the lease expires or a client logs out and releases its IP address, the server reclaims the IP address, which can then be allocated to other clients. To continue using this IP address, the client must renew its IP address lease."-from google

This situation had nothing to do with DHCP lease expiration. It's simply there are not enough IP addresses in the DHCP pool. Therefore, when the smart TV was connected to the WIFI and assigned an IP address, the bank laptop tried to connect, there were no more IP addresses available, causing it to lose network access. That is how DHCP exhaustion works

Sounds like "A. DHCP scope exhaustion" to me. Once it is on the WiFi one other laptop lost access,. Sounds like you are taking the last IP to me. Call me out if I am mistaken.

DHCP scope exhaustion occurs when there are no more available IP addresses in the DHCP pool for devices to obtain an IP address. This issue would typically affect new devices trying to connect, and it wouldn't directly cause the bank laptop to lose network access.

This is not true if they turned the tv on first and it grabbed the last available IP, then turned on the laptop.
