Which password meets ESXi 6.x host password requirements?
A. 8kMVnn2x!
B. zNgtnJBA2
C. Nvgt34kn44
D. !b74wr Answer: A
Explanation:
A valid password requires a mix of upper and lower case letters, digits, and other characters. You can use a 7-character long password with characters from at least three of these four classes, or a 6-character long password containing characters from all the classes. A password that begins with an upper case letter and ends with a numerical digit does not count towards the number of character classes used. It is recommended that the password does not contain the username.
A passphrase requires at least 3 words, can be 8 to 40 characters long, and must contain enough different characters.
