What may be a cause for failure to unmount an NFS datastore?

A. It has active snapshot files.

B. It is being used for High Availability (HA) heartbeat.

C. It is part of a Cluster.

D. It is managed by Distributed Resource Scheduler (DRS).

An application running in a virtual machine is experiencing performance issues. When utilizing performance monitoring utilities, it is noted that the CPU Utilization of the application is at 100%.

Which two scenarios are probable causes of the CPU contention for the application? (Choose two.)

A. There is a network I/O constraint.

B. There is a storage I/O constraint.

C. There is insufficient disk space assigned to the virtual machine.

D. The application is not virtualization aware.

An administrator is using the Host Failures to Tolerate Admission Control Policy for a vSphere High Availability (HA) cluster. When configuring this setting on the cluster, the administrator sees this error message:

Insufficient resources to satisfy HA failover level on cluster

What are two likely causes for the error? (Choose two.)

A. The hosts in the cluster are disconnected.

B. A host in the cluster is displaying an HA error.

C. Distributed Resource Scheduler has not been configured on the cluster.

D. Virtual Machine Component Protection has not been turned on.

An administrator wants to add a web server to an existing multi-tier application consisting of three virtual machines: A web server A database server An application server

The web server should be added to the application when the primary web server reaches: 70% vCPU utilization 55% active memory

Which option will achieve this result?

A. Create a virtual machine alarm with an action to run a script that starts a new instance of the web server.

B. Create a host cpu and memory alarm with an action to run a script that starts a new instance of the webserver.

C. Configure High Availability application monitoring for the web server and set it to trigger deployment of a new instance of the web server.

D. Configure Fault Tolerance on the virtual machine and leave the secondary machine disabled until needed.

An administrator is monitoring a fully automated vSphere cluster configured with HA, DRS, DPM and EVC. The administrator notices that the cluster has a greater than expected load imbalance.

Why is this happening?

A. The DRS Migration Threshold is not aggressive enough.

B. The EVC baseline is masking too many CPU features.

C. The HA VM Restart Priority is set too high for several virtual machines.

D. The DPM Threshold is not aggressive enough.
