QUESTION 50
An administrator is creating a virtual machine that will be running "Windows 2008 Enterprise (64-bit). The application to installed in the virtual machine requires eight vCPUs to run effectively.
During installation, the only available options are one, two, three, or four vCPUs.
What condition explains the available vCPU selections?
A. The virtual machine hardware version is 8.
B. The guest operating system for the virtual machine is 64-bit
C. The ESXi host has two AMD dual-core CPUs
D. The ESXi host has two Intel dual-core CPUs
Answer: C

QUESTION 52
What is the most appropriate way to test a virtual machine enabled for VMware Fault Tolerance?
A. Cause a failure on the ESXi host running the primary virtual machine
B. Cause a failure on an application within the primary virtual machine
C. Disable network connectivity to the primary virtual machine
D. Cause a failure on the primary virtual machine
Answer: A

The following are proper testing scenarios with their expected outcomes:
Note: The following tests assume two hosts, Host A and Host B, with the primary fault tolerant virtual machine running on Host A and the secondary virtual machine running on Host B.
Select the Test Failover Function from the Fault Tolerance menu on the virtual machine.
This tests the Fault Tolerance functionally in a fully supported and non-invasive way. In this scenario, the virtual machine fails over from Host A to Host B, and a secondary virtual machine is started back up again. VMware HA failure does not occur in this case.
Host A complete failover
This scenario can be accomplished by pulling the host power cable, rebooting the host, or powering off the host from a remote KVM (such as iLO, DRAC, or RSA). The secondary virtual machine on Host B takes over immediately and continues to process information for the virtual machine. VMware HA failover occurs.
Virtual machine process on Host A fails
This scenario can be accomplished by terminating the active process for the virtual machine by logging into Host A. The secondary virtual machine takes over and no VMware HA failure occurs. VMware does not recommend testing in this way. For more information on terminating a virtual machine, see Powering off an unresponsive virtual machine on an ESX host (1004340)
QUESTION 53
What are two network load-balancing policies for a vNetwork Distributed Switch? (Choose two)
A. Route based on source destination MAC hash
B. Route using Round Robin
C. Route based on the originating virtual port ID
D. Route based on IP hash
Answer: AC
Explanation: (REVIEWED) **** Debated A for D *****
11-9-2011 Debated again (giobuon) – so now there is a screen shot SHOWING what is right…
Argument: Vendor documentation and the fact these were the right answers on a 410 only proves the point further. Word "NETWORK" load-balancing policies… However there is an option on vSphere 5 distributed switches that is called "Route based on Physical NIC Load". For now these two are the correct answers unless someone can provide proof that they aren’t.
(According to Cisco these are the only two teaming policies offered for network load balancing for DVS)
