Free CompTIA A+ 220-1102 Practice Question

The correct answer is 'A minimum of 14 characters, including upper and lower case letters, numbers, and symbols.' This answer is correct because it aligns best with the industry best practices that recommend the use of long passwords with a mix of various character types to increase the complexity and make it more resistant to brute-force attacks. Shorter passwords with fewer character requirements, such as 'At least 8 characters including one uppercase letter and one number' and 'At least 10 characters in length using only alphabetic characters,' are easier for attackers to guess or crack using automated tools. 'Mandating regular password changes every 30 days' does not necessarily increase complexity and can lead to weaker passwords if users only make minimal changes to their previous passwords or begin writing passwords down to remember the frequent changes.
