A request has been made to the SAN administrator to provision a new LUN. A LUN (LUN 6) is created, and the SAN administrator presents the LUN to an ESXi host, using the storage array SAN management software. After a rescan operation on the ESXi host, the LUN fails to be recognized by the host. Other LUNs from the same storage array are visible.

Which two conditions are most likely to cause the error described? (Choose two.)

An administrator wants to apply disk shares to ensure proper storage performance.

On which object are these shares configured?

Users are complaining that they cannot access their files on a file server virtual machine. The vSphere Client shows that a triggered alarm stating disk latency is beyond the default threshold for the datastore where the file server virtual machine is located. The path selection policy has been set by the ESXi host to Fixed with default path settings.

Which two options could be used to increase performance of the file server virtual machine? (Choose two.)

An administrator is updating a program running on a virtual machine. The update file has been downloaded as an .iso file and placed on a shared NFS datastore. An attempt to mount the .iso file to the virtual machine fails, but subsequent testing shows that the .iso file can be mounted to a virtual machine running on another ESXi host.

Which step can be taken to enable access to the .iso file for the affected virtual machine?

A new LUN has been presented to two ESXi hosts: ESXiA and ESXiB. The LUN can be seen from both servers. A vSphere Client attached to ESXiB is used to create a VMFS datastore on the LUN. The new datastore is visible on ESXiB but not on ESXiA.

What step must be taken to make the datastore visible to ESXiA?

An administrator receives a complaint that a virtual machine is performing poorly. The user attributes the issue to poor storage performance.

If the storage array is the bottleneck, which two counters would be higher than normal? (Choose two.)

An administrator determines that a virtual machine configured for the Development port group lost network connectivity when it was migrated with vMotion from one ESXi 5.x host to another. The administrator notices that machines configured for the Production port group are not experiencing the issue. The hosts have port groups with the following network configuration:

Host A:

1. Production (VLAN 100)

2. Development

Host B:

1. Production (VLAN 100)

2. Development (VLAN 200)

Which two conditions would explain the loss of network connectivity for the virtual machine? (Choose two.)

An administrator is setting up vMotion in a vSphere environment. A migration is run to test the configuration, but fails.

On which vSphere component does vMotion need to be enabled?

A user attempts a remote SSH connection to a newly-installed ESXi 5.x host to execute some commands. The SSH connection attempt fails, though the user is able to receive a ICMP ping back from the host.

Which two conditions might cause the issue? (Choose two.)

A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts with the following vNetwork Standard Switch configuration:

1. Switch A: two vmnics, one port group named sFTP-PG

2. Switch B: one vmnic, one port group named Web-PG

3. All vmnics are trunked to the same physical switch.

DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that no more than half of the virtual machines run on any given host. The virtual machines on WebPG are experiencing significant network latency. The network team has determined that a performance bottleneck is occurring at the ESXi host level.

Which solution will require the least amount of administrative work and the least amount of service interruption?
