• Question 153:

  Users of an application are reporting performance issues. The following performance values are observed in the vSphere Web Client:

  Host CPU utilization is 90%

  Virtual Machine memory utilization is consistently greater than 90%

  CPU Ready values are higher than 20%

  What could be the cause of the application performance issue?

  A. The host is lacking the CPU resources required to meet the demand.
  B. The host is lacking the memory resources required to meet the demand.
  C. The virtual machine is lacking the CPU resources required to meet the demand.
  D. The virtual machine is lacking the memory resources required to meet the demand.
  A. The host is lacking the CPU resources required to meet the demand.

• Question 155:

  An administrator is moving a virtual machine into a resource pool. The VM and resource pool are configured as shown:

  VM configuration: 2GHz CPU reservation 1GB Memory limit

  Resource Pool configuration: 6GHz CPU reservation 1GB Memory reservation No limit to memory

  What happens to the virtual machine's resource settings when it is moved into the pool?

  A. The VM inherits the resource settings of the resource pool if expandable reservations is enabled.
  B. The VM's reservations and limits are ignored and removed.
  C. The VM keeps the 2GHz CPU reservation but receives the 1GB memory reservation.
  D. The VM keeps the 2GHz CPU reservation and the 1GB Memory limit.
  D. The VM keeps the 2GHz CPU reservation and the 1GB Memory limit.

  ---

  When the VM is moved into the pool, it keeps the 2 GHz CPU reservation and 1 GB memory limit.

  A. Applications need to be continuously available to users.
  B. Applications without native clustering capabilities can be protected.
  C. Custom clustering solutions are complicated to configure and maintain.

  ---

  With Fault tolerance, applications need to be continuously available to users, application without native clustering capabilities can be protected and custom clustering solutions are complicated to configure and maintain. Reference: https://www.vmware.com/products/vsphere/features/availability

• Question 157:

  An administrator is attempting to remove an ESXi 6.x host from a vSphere Distributed Switch (vDS). When the administrator attempts to remove the host, the following error is observed:

  The resource '16' is still in use.

  What three steps are needed to successfully remove the host from the switch? (Choose three.)

  A. Select Manage Ports on the vDS for the host.
  B. Locate all ports currently in use on the vDS for the host.
  C. Migrate or delete any vmkernel or virtual machine adapters associated with the switch.
  D. Remove all network cards from the switch before trying to remove the host.
  E. Create a standard switch for everything to be automatically be migrated to.
  A. Select Manage Ports on the vDS for the host.
  B. Locate all ports currently in use on the vDS for the host.
  C. Migrate or delete any vmkernel or virtual machine adapters associated with the switch.

  ---

  To remove the host from the switch select manage ports on the vDS along with locating all ports currently in use. Migrate or delete any vmkernel or virtual machine adapters.
