QUESTION 56
An administrator receives a call indicating users reported extremely slow access to virtual machines the previous evening. Access to virtual machines performs as expected as checked by the administrator. Ove
r the course of several days, the administrator continues to receive calls about the issue, which appears to occur at intermittent times each evening.
Which step can be taken to collect information about the issue?
A. Create a condition alarm to alert when Datastore Disk Usage (*) exceeds 70%
B. Collect esxtop performance data in batch mode and analyze total number of I/O operations (CMDS/s) metrics
C. Create an event alarm to alert when a storage device is disconnected
D. Collect esxtop performance data in batch mode and analyze average device latency (DAVG/cm-d) metrics.
Answer: D
Explanation:
I didn’t find oficial docs to that question but using logic, I choose option D.
A – Used for space use.
B – Depend on your Storage Array you can obtain more or less I/O operations, its good to look this but only for help.
C – Storage is not disconnected is high used, that answer didn’t work.
QUESTION 57
An administrator wishes to send traffic from a vNetwork Distributed Switch to a collector virtual machine for analysis. vSphere 5 has been deployed in the datacenter.
Which two configurations will enable the functionality? (Choose two)
A. The source and target virtual machines must be on the same vNetwork Switch.
B. The source and target virtual machines must both be on a vNetwork Distributed Switch, but can be on any vDS in the datacenter.
C. The port group on the distributed port must have Promiscuous Mode enabled.
D. The port group on distributed port must have NetFlow enabled.

QUESTION 58
Click the exhibit button:
An administrator is configuring vMotion in their environment. As a part of the implementation, an administrator is examining resource mapping for virtual machines.
What is a likely cause of the error shown in the exhibit?
A. vMotion has been disabled because the Production network does not exist on both ESXi host.
B. vMotion has not been enabled on the Production port group.
C. vMotion has not been enabled on a VMkernel port group.
D. vMotion has been disabled because datastored is not presented to both ESXi hosts.
Answer: C
Explanation:
Challenged by Kreden 11-14-2011 Believes answer is D – However, if you read the following its obviously incorrect – C is still the correct answer.
This only shows up in the Maps when the vmotion OPTION is not checked in the PORT group – hence vMotion is DISABLED!
Other Notes: vMotion doesn’t need a "production" network it can use any network. It also should not be using a "production" network. Datastore has nothing to do with vMotion in this diagram – this is Maps – it would give a vmotion error if it wasn’t on the datastore not a vmotion disabled..
