You have a Windows 2003 Server virtual machine (VM) that is experiencing performance problems.
Task Manager displays the following information:
CPU Usage: 85%
Memory Available: 3 GB
Network Utilization: 25%
vCenter Server displays this additional information:
ESXi host CPU Utilization: 60%
VMkernel Swap Activity: None
Average Network Usage: 900 Mbps
What is the most likely cause for the performance problems?

B. The ESXi host is CPU constrained.
C. The ESXi host NIC is being over utilized.
D. The ESXi host needs more memory installed.

B. VMkernel swap files must be stored locally on the ESXi host
C. 1 per virtual machine
D. 1 per virtual disk
You are running into disk contention problems on a VMFS datastore. Which two actions will resolve this problem? (Choose two.)
A. Adjust disk shares for each ESXi host accessing this datastore.
B. Adjust disk shares for all virtual machines accessing this datastore from the same ESXi host
C. Move some of the virtual machines from this VMFS datastore to another datastore on the same LUN.
D. Move some of the virtual machines from this VMFS datastore to another datastore on a different LUN.
What two things are controlled by the DRS automation level? (Choose two.)
A. VM isolation response
B. VM restart priority

B. Access is immediately removed
C. Access is unaffected until either the ESXi host or the iSCSI Array are restarted
D. Access is removed on the next rescan
An administrator is configuring a vNetwork Standard Switch for load balancing. The physical network is configured for switch-assisted load balancing using EtherChannel. Which load-balancing policy must be used to support this configuration?
