Regarding a qualification pretest for taking an ESX deploy and configuration course. I believe most of my answers are correct there are a few questions that maybe you can point me in the right direction.
Thanks
1. You are performing a new installation of ESX Server 3.X. Which statement is true? (Choose One)
A. The Service Console memory depends on the number of Virtual Machines you plan to run.
B. You should always have the SAN connected during installation so that it will be properly discovered during installation.
C. Root login by SSH is disabled by default.
D. The ESX Server license is applied during the initial installation process.
Answer=C
2. You have installed ESX Server 3.X and VirtualCenter 2.X and you need to create new network switches and manage storage. Which statement is true? (Choose One)
A. You can use the ESX Server web access.
B. You can use the VirtualCenter web access.
C. You can use the Virtual Infrastructure Client to connect to VirtualCenter or ESX Server directly.
D. Youcan use the Virtual Infrastructure Client to VirtualCenter but not ESX Server directly
Answer=D
3. You have root level access on an ESX Server and attempt to log onto VirtualCenter as user root using the Virtual Infrastructure Client. What happens? (Choose One)
A. The login would be successful, as a root account is created in VirtualCenter when the ESX Server starts being managed by VirtualCenter. This is why you furnish the root password when you add the ESX Server to its inventory.
B. The login would be successful, as ESX Server would authenticate the account as a proxy. .
C. The login would fail, as ESX Server uses Linux structure permissions, and VirtualCenter uses Windows authentication.
D. The login would fail, as the passwords for the root account and the VirtualCenter administrator account need to be identical to function properly.
answer= C
4. You have root level access on an ESX Server and attempt to log onto the ESX Server as user root using the Virtual Infrastructure Client. What happens? (Choose One)
A. The login would be successful, as a root account is in the security context of ESX Server.
B. The login would fail because the Virtual Infrastructure Client can only communicate directly with
VirtualCenter.
C. The login would fail, as you must log into ESX Server using the VPX user account that VirtualCenter
creates to replace the root account.
D. The login would fail, as root access to ESX Server is blocked by default.
answer =A
5. You are a member of the “Power Users” group in a Windows AD domain. When you log on using the Virtual Infrastructure Client, what role, by default, is automatically assigned within VirtualCenter? (Choose One)
A. You would be assigned the role of Virtual Machine Power User.
B. You would be assigned the role of Virtual Machine User.
C. You would be assigned the role of Read-Only User.
D. You would have no access
answer = D
6. You are adding a new LUN to an existing storage subsystem and want to make it visible to all ESX Servers in a Datacenter. What is the best way to insure that all ESX Servers will be able to recognize the new storage? (Choose One)
A. Scan for New Storage Devices on any ESX Server and the results are populated by VirtualCenter to all the other ESX Servers.
B. Scan for New Storage Devices on each ESX Server.
C. Scan for New VMFS Volumes on any ESX Server and the results are populated by VirtualCenter to all the other ESX Servers..
D. Scan for New VMFS Volumes on each ESX Server.
E. The new VMFS Volume is discovered automatically by periodic rescans, so no action is needed.
Unsure but I think C
7. You are adding a new Storage Subsystem to your SAN, and want to make it, and any VMFS Volumes it may contain visible to all ESX Servers in a Datacenter. What is the best way to insure that all ESX Servers will be able to recognize the new storage? (Choose One)
A. Scan for New VMFS Volumes on any ESX Server and the results are populated by VirtualCenter to all the other ESX Servers..
B. Scan for New VMFS Volumes on each ESX Server.
C. Scan for New Storage Devices and New VMFS Volumes on any ESX Server and the results are populated by VirtualCenter to all the other ESX Servers..
D. Scan for New Storage Devices and New VMFS Volumes on each ESX Server. .
E. The new storage is discovered automatically by periodic rescans, so no action is needed.
Also C
8. You want redundant network connections for all ESX Server network functions in a secure environment, but your server only has two physical network interfaces. What action would you take to accomplish this? (Choose One)
A. Connect all services to a common network switch and use VLAN port groups to isolate the traffic. Connect two physical network interfaces to a common switch and use NIC teaming.
B. Connect the two physical network interfaces to separate switches and create identical port types on each switch. Use VLAN port groups to isolate the traffic.
C. Connect the two physical network interfaces to separate switches and team the network switches. Use VLAN port groups to isolate the traffic.
D. Connect the two physical network interfaces to separate switches, and divide the services between the two network switches. Assign VLANs at the physical switch for security.
E. The Service Console must be on a separate physical network interface, so you cannot create a redundant connection.
D?
9. You want to protect your Virtual Machines from ESX Server level failures. How can this be accomplished? (Choose One)
A. Use DRS and set fully automated restoration.
B. Use DRS and set isolation response to on.
C. Use VMware HA to perform a VMotion transfer if a failure is detected.
D. Use VMware HA to force other Virtual Machines to take over the applications function.
E. Use VMware HA to force other ESX Servers to take ownership of the Virtual Machines from the failed ESX Server.
Answer E
10. You are experiencing problems with Virtual Machines migrating with VMotion,though the Virtual Machines function correctly otherwise.
What COULD NOT cause this problem? (Choose One)
A. Not all CPUs in the ESX servers involved support SSE3 instruction sets.
B. Not all CPUs in the ESX servers involved support NX/XD bits.
C. The servers are a mix of Intel and AMD CPUs.
D. The Datastore is not visible to both the source and destination ESX Server.
E. The Virtual Machine uses RDM, which does not support VMotion.
answer E
11. You are considering using NFS with ESX Server 3.X. Which is a valid design constraint? (Choose One)
A. NFS does not support VMotion.
B. NFS does not support RDM.
C. NFS does not support VMware HA.
D. NFS does not support DRS.
answer B
12. You have a VI-3 Infrastructure with one DRS Cluster and all ESX Servers and Virtual Machines are part of that cluster. Which statement is true? (Choose One)
A. The VMkernel swap file can be on local storage and there is one per ESX Server.
B. The VMkernel swap file can be on local storage and there is one per Virtual Machine.
C. The VMkernel swap file must be on shared storage and there is one per ESX Server.
D. The VMkernel swap file must be on shared storage and there is one per Virtual Machine.
E. The VMkernel swap file can be on either local or shared storage and can be specified on either a per ESX Server or per Virtual Machine basis.
answer A
13. You have a VI-3 Infrastructure with one DRS Cluster and all ESX Servers and Virtual Machines are part of that cluster. Which statement is true? (Choose One)
A. The Virtual Machine Configuration File can be on local storage and there is one per ESX Server.
B. The Virtual Machine Configuration File can be replicated to each ESX Servers home directory, and
there is one per Virtual Machine.
C. The Virtual Machine Configuration File must be on shared storage and there is one per Virtual Machine.
D. The Virtual Machine configuration information is now stored in VirtualCenter, with a replica is stored in the esx.conf file of each ESX Server.
answer C
