Question 1

Host profiles can be exported to a file in what file format?
A)VMware profile format (.vpf)
B)VMware host format (.vhf)
C)VMware host profile (.vhp)
D)VMware host profile format (.vhpf)

Accepted Answer

Host profiles can be exported to a file in the VMware profile format (.vpf). In the Host Profiles view page, select the profile to export from the profile list, right-click the profile and select Export Profile.

Question 2

Hosts can be checked for profile compliance from which locations? Select two.
A)Host's profile view.
B)VMs and Templates view.
C)The host's context menu.
D)vCenter Update Manager main view.

Accepted Answer

A Host can be checked for profile compliance from the Host Profiles view and the host's context menu. Regularly checking hosts for compliance ensures that the host is still configured as expected.

Question 3

Guy, a VMware administrator, is trying to prevent a particular test ESX host from accessing a LUN that is used specifically for live environments. How might he best achieve this?
A)He could mask the LUN in question using the #esxcli corestorage claimrule add commandlet.
B)He could remove the Fibre Channel cable that connected to the LUN.
C)He could alter the vCenter Server permissions for the connection account.
D)He could mask the LUN in question using the #esxcli corestorage claimrule delete commandlet.

Accepted Answer

The #esxcli corestorage claimrule add commandlet could be used to prevent an ESX host from accessing a LUN. This would effectively stop a particular HBA from being able to view the LUN in question. Another option would be to use the vendor SAN administration toolset to deny access to the LUN for the host in question.

Question 4

Guy, a VMware administrator, has removed an administrator that is suspected of malpractice from a group that controls the ability to remove hosts from vCenter. Several days after Guy has completed this task, he receives a call from his manager stating that the administrator Guy removed from the group has been removing hosts from vCenter. Which of the following is the most likely reason for the administrator's continued ability to remove hosts?
A)Guy is incompetent and did not remove the permissions correctly.
B)Permission changes take effect up to 10 days after being made.
C)The rogue administrator was specifically granted permissions through his user account.
D)The "no VMware remove" option was ticked in the rogue administrator's AD account.

Accepted Answer

The administrator is still able to remove the hosts because the permission was directly assigned to his account in addition to the group membership. Permissions assigned directly to a user are not removed when that user's account is removed from a group granting the same permission set.

Question 5

ESX and ESXi can be installed from which of the following locations? Select three.
A)Floppy disk
B)DVD
C)USB
D)Ticker tape
E)PXE boot

Accepted Answer

ESX/i can be installed from several locations. USB drives, DVD drives and PXE boot are all supported installation locations. The install image would not fit onto a 1.4MB floppy disk, and ticker tape is a legacy way of transferring electronic data that ceased operation in the 1970s.

Question 6

Of the following options, which are are recommended post-installation activities for ESXi that increase security? Select two.
A)Change the root password.
B)Configure lockdown mode.
C)Destroy the installation media.
D)Write the root password down and put it in a safe place.
E)Remove floppy disks from the drive.

Accepted Answer

After installing ESXi the root password is blank, and it is recommended that you change it immediately. Another good practice is to configure lockdown mode; this stops any interaction with the server other than through the vCenter server. When in lockdown mode, a host cannot be managed through the local console, from a vMA or via external management tools.

Question 7

What should be configured on a 10GbE adapter for maximum throughput of ISCSI-based storage?
A)No lock standard
B)MTU of 9000
C)None locking architecture
D)MTU of 256

Accepted Answer

An MTU of 9000 (Jumbo Frames) should be configured on a 10GbE adapter for maximum throughput of ISCSI based storage. This allows the frames to be sent as 9kB instead of 1.5kB. Note that every link in the storage chain has to be set to an MTU of 9000 (Jumbo Frames) or it will not work.

Question 8

Guy, a VMware administrator, has just received confirmation that his LUN request has been granted by the storage team. He has been assured that the LUN has been created and that the ESX environment should be able to use the LUN immediately. When Guy tries to add the new LUN to his ESX system, he does not see the newly created LUN. What should Guy do next?
A)Reboot all hosts; LUNS are only visible after a reboot.
B)Call the storage team and complain about their incompetence.
C)Perform a storage rescan.

Accepted Answer

Guy should perform a storage rescan to allow the ESX hosts to recognize the newly created LUN. Storage rescans do occur at regular intervals, but you can issue a rescan immediately.

Question 9

Which path selection policy allows for I/O to be spread across multiple paths to active-active storage arrays?
A)Fixed
B)Fixed AP
C)Round Robin
D)Most recently used

Accepted Answer

Round Robin path selection policy allows for I/O to be spread across multiple paths to active-active storage arrays. An example of this would be using multiple VMkernel ports to connect ISCSI-based storage with multiple controllers in an active-active configuration. This will spread the I/O load across multiple paths to multiple controllers, thereby greatly increasing throughput and decreasing latency.
