QUESTION 23
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.

QUESTION 24
An administrator would like to use a passphrase for their ESXi 6.x hosts which has these characteristics:

– Minimum of 21 characters
– Minimum of 2 words

Which advanced options must be set to allow this passphrase configuration to be used?

A.    retry=3 min=disabled, disabled, 7, 21, 7 passphrase=2
B.    retry=3 min=disabled, disabled, 21, 7, 7 passphrase=2
C.    retry=3 min=disabled, disabled, 2, 21, 7
D.    retry=3 min=disabled, disabled, 21, 21, 2

Answer: B
Explanation:
To force a specific password complexity and disable all others, replace the number with the word with disabled. For example, to force passwords containing characters from all four-character classes: password requisite /lib/security/$ISA/pam_passwdqc.so retry=3 min= disabled,disabled,disabled,disabled,7

QUESTION 25
Which Advanced Setting should be created for the vCenter Server to change the expiration policy of the vpxuser password?

A.    VimPasswordExpirationInDays
B.    VimExpirationPasswordDays
C.    VimPassExpirationInDays
D.    VimPasswordRefreshDays

Answer: A
Explanation:
vCenter Server creates the vpxuser account on each ESX/ESXi host that it manages. The password for each vpxuser account is auto-generated when an ESX/ESXi host is added. The password is updated by default every 30 days.
To modify default password settings:
Connect vSphere Client to vCenter Server.
Click Administration > vCenter Server Settings > Advanced Settings. Scroll to the parameter VirtualCenter.VimPasswordExpirationInDays and change the value from the default.

Both upgraded and newly created VMFS-5 support single-extent volumes up to 64TB and both support VMDK sizes of ~2TB, no matter what the VMFS file-block size is. However additional differences, although minor, should be considered when making a decision whether to upgrade to VMFS-5 or create new VMFS-5 volumes.

When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.
