A company has been utilizing templates in its environment. It is running a 10-node ESXi 5.x Cluster and DRS has not been configured. Several virtual machines have been deployed from this template and successfully powered on, but a newly deployed virtual machine will not power on. There appears to be adequate CPU and Memory resources available on the host.

Which three things can be done to allow more virtual machines to be deployed into the cluster from this template? (Choose three.)

Deploy the virtual machine to a different host using the same datastore

Enable DRS on the cluster to balance the virtual load out across hosts

Increase the virtual machine memory reservation

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.)

The configured VLAN for Production on Host A is incorrect.

The configured VLAN for Development on Host B is incorrect.

An improper native VLAN is configured on the uplinks to Host A.

An improper native VLAN is configured on the uplinks to Host B.
