Abrute-force attackis a type of attack that tries to guess the user's password by systematically trying all possible combinations of characters until the correct one is found12.

A brute-force attack can be performed by an attacker who has physical access to the user's computer or by a remote attacker who can intercept the user's network traffic or access the user's online account12.

A brute-force attack can prevent the user from logging in after locking the computer, as the attacker may have changed the password or locked the account after guessing the password12.

Therefore, option A is the correct answer, as a brute-force attack is the most likely attack against the user in this scenario.

The other options are incorrect, as they are not likely to cause the user's login problem.

Option B is incorrect because anon-path attack(also known as a man-in-the-middle attack) is a type of attack that intercepts and modifies the user's network traffic without the user's knowledge12.An on-path attack can compromise the user's data or credentials, but it does not prevent the user from logging in after locking the computer, unless the attacker also performs a brute-force attack12.

Option C is incorrect because adeauthentication attackis a type of attack that disconnects the user from a wireless network by sending spoofed deauthentication frames to the user's device or the access point12.A deauthentication attack can disrupt the user's network connectivity, but it does not prevent the user from logging in after locking the computer, unless the user needs to authenticate to the wireless network again12.

Option D is incorrect because aphishing attackis a type of attack that tricks the user into revealing sensitive information or clicking malicious links by sending fraudulent emails or messages that appear to be from legitimate sources12.A phishing attack can compromise the user's data or credentials, but it does not prevent the user from logging in after locking the computer, unless the user falls for the phishing attempt and changes the password or clicks a malicious link that performs a brute-force attack12.

It does this by using a two-level hierarchy of switches, where the spine switches connect to the leaf switches, which in turn connect to the end hosts. This reduces the number of hops a packet must take from one host to another, thus reducing latency. According to the CompTIA Network+ N10-008 Exam Guide, the Spine and Leaf topology is a modern architecture that is used to reduce latency in large networks.

The question asks about the best method to use for the network team to receive UPS status notifications after a critical power issue.The UPS is an uninterruptible power supply that provides backup power to the network devices in case of a power outage or surge1.

The answer is traps, which are unsolicited messages that are sent from an agent to a manager to notify about an event or a condition that requires attention2.Traps can be used to alert the network team about the UPS status changes, such as battery level, load, temperature, or power failure3.

MB, NetFlow, and Syslog are not the correct answers, because they are not the best methods to use for the UPS status notifications.MB stands for megabyte, which is a unit of data storage4. NetFlow is a protocol that collects and analyzes network traffic data. Syslog is a standard for logging and monitoring system events. These methods are not designed to send alerts about the UPS status changes, and they may not be reliable or timely in case of a critical power issue.Reference:

The most likely frequency range that the network consultant will have to support is2.4GHz.This is because the most common legacy wireless standards, 802.11b and 802.11g, use the 2.4GHz range1. IEEE 802.11a uses 5GHz exclusively, and 5.9GHz and 6GHz are not widely used by legacy equipment. Therefore,

A . 2.4GHz is the correct answer.
