Question

A network administrator is issuing the login block-for 180 attempts 2 within 30 command on a router. Which threat is the network administrator trying to prevent?

a.) a user who is trying to guess a password to access the router
b.) a worm that is attempting to access another part of the network
c.) an unidentified individual who is trying to access the network equipment room
d.) a device that is trying to inspect the traffic on a link

Answer 1

The network administrator is implementing a security measure to prevent a user from attempting to guess the router password through brute-force login attempts.

Step-by-step explanation:

The network administrator is issuing the login block-for 180 attempts 2 within 30 command on a router to prevent threat a.). This security measure is designed to thwart a user who is trying to guess a password to access the router. The command essentially blocks login attempts for 180 seconds if there are 2 failed attempts within a 30-second window.

This is a proactive step to counteract brute-force attempts, where an attacker tries many passwords or passphrases with the hope of eventually guessing correctly.
