CompTIA Security+ SY0-701 Practice Question

The correct answer 'Password length of 16 mixed characters with no dictionary words' embodies multiple best practices for password security, including a long length and the avoidance of dictionary words which can be susceptible to dictionary attacks. Using common keyboard paths (like 'qwerty') provides patterns that can be easily exploited, and relying solely on length without considering the use of mixed character types or avoiding common words can still lead to vulnerabilities. While having a password expiration policy can be a beneficial security practice, without further context of password complexity requirements, it does not inherently guarantee a high level of security.
