Which two guidelines are appropriate for creating strong passwords? (Choose two.)

• Include letters, numbers, and symbols.
• Passwords should contain symbols only.
• Change the password once each year.
• Use at least eight characters.
• Use only upper case and numeric values in passwords.

Explanation: Strong passwords should be at least eight characters, and should include upper and lower case letters, numbers, and symbols. Although passwords should be changed regularly as specified in the local security policy, the amount of time between changes has no effect on the creation of strong passwords. Limiting a password to only symbols, or to only numbers and upper case letters, does not provide the strongest password possible.
