This is the most likely cause of the user’s connection issues, because the ARP table of the switch shows that there are two devices with the same IP address of 192.168.1.10, but different MAC addresses. This indicates that there is an IP address conflict on the network, where two devices are trying to use the same IP address. This can cause intermittent connectivity issues, as the switch may not be able to forward packets to the correct destination .
A network technician is configuring a wireless network that consists of multiple APS for better coverage and allows roaming between the APS. Which of the following types of SSIDs should the technician configure?
Basic Service Set
Independent Basic Service Set
Extended Service Set
Distribution System Service
Answer: C
An extended service set (ESS) is a type of SSID that allows multiple access points (APs) to share the same SSID and provide seamless roaming for wireless clients. An ESS consists of two or more basic service sets (BSSs), which are individual APs with their own SSIDs. A distribution system (DS), such as a wired Ethernet LAN, connects the BSSs and enables data transfer between them. A wireless client can associate with any AP in the ESS and move from one BSS to another without losing connectivity or reauthenticating.

Which of the following passwords would provide the best defense against a brute-force attack?
ThislsMyPasswordForWork
Qwerty!@#$
Password! 1
T5!8j5
Answer: D
A brute-force attack is a method of guessing passwords by trying every possible combination of characters until the correct one is found. The longer and more complex the password, the harder it is to crack by brute-force. A password that provides the best defense against a brute-force attack should have a combination of uppercase and lowercase letters, numbers, and special characters, and should be as long as possible. The password T5!8j5 meets these criteria, while the other options are either too short, too simple, or too common.
