QUESTION 81
Scenario: Nether Tech has a datacenter in a XenServer pool consisting of four hosts that are connected to a SAN. This pool is used as the hosting infrastructure for Nether Tech’s XenApp and XenDesktop farms. Extensive load testing has shown that approximately 100 users can be hosted by each XenServer host. The hosting infrastructure at Nether Tech is currently hosting desktops and applications for 350 users. A recent acquisition will require the environment to host desktops and applications for 175 additional users. A Citrix Engineer has been tasked with adding the necessary number of hosts to ensure loss of a host does NOT result in an overload of the hosting infrastructure and to ensure that the infrastructure is capable of hosting the additional users when the time comes. How many XenServer hosts should the engineer add to the pool, assuming the new hosts are identical to the current hosts in the pool?
A. 1
B. 2
C. 3
D. 4
Answer: C
QUESTION 82
