Question 1

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 2

What step is required for an ESX/i host to boot from SAN?
A)The adapter must be enabled for this feature.
B)The adapter must be an Emulex.
C)The adapter must be a Qlogic.
D)The adapter must be 4Gb.

Accepted Answer

In order for an ESX/i host to boot from SAN, the adapter must be set to enable boot from SAN. The procedure for enabling feature varies from vendor to vendor.

Question 3

What is the minimum space required for the ESX boot disk?
A)600 MB
B)1.25 GB
C)1600 MB
D)2 GB

Accepted Answer

The ESX boot disk requires a minimum of 1.25 GB of free space. It includes the vmkcore and /boot partitions. The /boot partition is 1100 MB in size and stores the information that is required to boot the ESX system.

Question 4

Guy, a VMware administrator, has set up a number of user accounts directly on an ESX host. After he returns from leave, the groups are no longer present on the ESX host when viewed through vCenter. What is the most likely reason for this?
A)After 7 days all user accounts created on an ESX host go into "dormant" mode.
B)The user accounts were deleted by the account scavenger process.
C)Groups created directly on an ESX host are not visible when viewed through vCenter.
D)Guy's account has defaulted to the "no-view" mode due to his absence.

Accepted Answer

The most likely reason for the accounts' not appearing is that accounts created while directly connected to an ESX host do not appear in vCenter. They would still appear if the connection were made directly to the host in question.

Question 5

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 6

Which of the following are components of vSphere? Select three.
A)VMware ESX
B)VMware Fail Tolerated
C)VMware vMotion
D)VMware Cluster Manager
E)VMware Fault Tolerance

Accepted Answer

Three components of vSphere are: VMware ESX (the hypervisor used for hosting virtual machines), VMware Fault Tolerance (a lockstep technology that allows for zero downtime of virtual machines in the event of a host failure) and VMware vMotion (the ability to live migrate a host from one ESX host to another with zero downtime).

Question 7

After you upgrade an ESX host, you notice anomalies in the operation of the host that indicate that the upgrade process was not successful. Which of the following options are true statements about the rollback process? Choose two.
A)Virtual machines that have been upgraded to the latest virtual hardware will be rolled back as part of the host rollback.
B)Any changes made to the service console are lost after the rollback.
C)A non-privileged operator can perform the rollback.
D)A reboot is required to complete the rollback.

Accepted Answer

Changes made to the service console after the upgrade will be lost as part of the rollback procedure, and a reboot is required to restore the previous version of ESX. After virtual machine hardware has been upgraded, a rollback of the host will not revert to the earlier version of virtual machine hardware. To prevent issues, a snapshot should be taken of the virtual machines prior to upgrading the host. Only a system administrator can perform the rollback.

Question 8

What are the advantages of deploying an ESXi host in place of an ESX host? Select two.
A)ESXi has a smaller footprint.
B)ESXi requires fewer patches to be applied.
C)ESXi allows the installation of third-party agents.
D)ESXi has a firewall and is more secure.

Accepted Answer

One of advantages of installing ESXi is that ESXi has significantly fewer lines of code and has a much reduced footprint. This allows it to be installed on much smaller disks or USB pen devices. The fact there is less code translates directly into fewer patches being needed. ESXi does not have a service console and therefore you cannot install third-party agents, nor does ESXi have a firewall; it is assumed that if you deploy ESXi that you will have a secure network with its own external firewall.

Question 9

Which of the following is a suggested best practice for installing agents in the ESX Service Console?
A)Have an extra CPU for every third-party tool.
B)Change the service console memory to 800 MB.
C)Install antivirus software in addition to any other agent.
D)Ensure the swap space is 50% greater than the size of the memory assigned to the service console.

Accepted Answer

When installing third-party agents, it is recommended that you increase the service console memory to its maximum of 800 MB. This is to allow for the additional overhead of the agents. It is also recommended that you increase the swap size to 1600 MB, double that of the physical memory. You can increase the service console memory either at the time of installation or through the vCenter client.

Question 10

What is the minimum license version of vSphere required to deploy host profiles?
A)Standard
B)Advanced
C)Enterprise Plus
D)Enterprise

Accepted Answer

Enterprise Plus is the minimum required licence required to deploy advanced features of vSphere. These advanced features include: host profiles, storage I/O control, Distributed Switches and network I/O control.
