Question

A pre-shared key (PSK) of fewer than _____ characters may be subject to an attack if that key is a common dictionary word.

A) 6
B) 8
C) 10
D) 12

Answer 1

A pre-shared key should have at least 8 characters to avoid becoming vulnerable to dictionary attacks. Shorter, commonly used passwords can be easily cracked, compromising network security.

Step-by-step explanation:

A pre-shared key (PSK) of fewer than 8 characters may be subject to an attack if that key is a common dictionary word. Shorter keys are easier to crack using brute force methods or by using a dictionary of common passwords. To ensure the security of a network, it is recommended that a PSK is not only longer but also complex, combining letters, numbers, and special characters to reduce the risk of unauthorized access.
