QUESTION 81
Users are having difficulty accessing a web server since a new web application was configured to run on sc-titanium03.vmeduc.com. The ABC vSphere client reports the error shown in the exhibit. DRS is set to fully automated mode, but the problem has not resolved.
Which of the following actions could be taken to resolve the issue?
A.Hot add another CPU to the web server virtual machine.
B.Add another server to the cluster.
C.Power down one or more virtual machines on the host running the web server virtual machine and migrate them to the other server in the cluster.
D.Migrate one or more running virtual machines on the host with the web server virtual machine to the other host in the cluster.
Answer: C
QUESTION 82
An administrator has a DRS/HA cluster with 5 ESX 4 Hosts. When trying to start a new web server Virtual Machine, an error is displayed saying insufficient resources exist for HA. Based on the HA configuration shown in the exhibit, how can this issue be resolved (Choose Two)?
A.Specify one of the servers to be a failover host
B.Allow virtual machines to be powered on even if they violate HA availability constraints.
C.Add another server to the cluster.
D.Change the percentage of resources to reserve to 30%.
Answer: BC
Explanation:
vSphere Help – Adding Inventory Objects : Editing a Cluster : Configure VMware HA Options
Select an Admission Control option.
Prevent VMs from being powered on if they violate availability constraints.
Allow VMs to be powered on even if they violate availability constraints. Select this option if you want the capability of powering on more virtual machines than the VMware HA failover level can support. If you select this option and power on enough virtual machines to violate failover, the cluster icon turns red and failover is no longer guaranteed. [B above]
Adding an additional host to the cluster will increases overall cluster resources, and should allow the VM to be started. [C above]
QUESTION 83
You have a newly set up 2 node cluster with HA and DRS enabled with DRS in fully automated mode. While testing DRS, you notice no virtual machines are moving from one ESX host to any other despite great disparity in resource utilization between the ESX hosts. Based on the information shown in the exhibit, what is the best solution for this problem?
A.Enable the VMkernel port for VMotion.
B.Remove the uplink used by the VMkernel port group and connect the proper uplink.
C.Disable HA for this cluster.
D.Change the IP address to 10.0.0.204 for the VMkernel interface.
E.No conclusions can be drawn from the exhibit.
Answer: E
QUESTION 84
DRS on a cluster is set to "Fully Automated", at its most aggressive setting. One particular server in the cluster is running at 98% CPU utilization. You notice that none of the virtual machines (VMs) are being placed on other servers. What are two possible causes of the problem? (Choose two.)
A.The VM options report_section = "8" in the DRS Settings on that cluster for all of the VMs on that server are set to Manual.
B.No other server in the cluster has enough resources to accommodate any of the VMs on the overloaded server.
C.An Affinity Rule for those particular VMs has been set to "Separate Virtual Machine" for the VMs on the overloaded host.
D.The guest OS types for the VMs do not support DRS.
Answer: AB
QUESTION 85
One of the hosts in a cluster of 10 hosts requires maintenance. This host is currently running two virtual machines (VMs) for a total of 30% CPU utilization. What is the best practice for repairing the hardware?
A.place the VMs on the host in Maintenance mode
B.place the host in Offline mode
C.repair the server while running VMs
D.place the host in Maintenance mode
Answer: D
Explanation:
vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 55.
You place a host in maintenance mode when you need to service it, for example, to install more memory. A host enters or leaves maintenance mode only as the result of a user request.
Virtual machines that are running on a host entering maintenance mode need to be migrated to another host (either manually or automatically by DRS) or shut down. The host is in a state of Entering Maintenance Mode until all running virtual machines are powered down or migrated to different hosts. You cannot power on virtual machines or migrate virtual machines to a host entering maintenance mode.
By placing the host in Maintenance mode you will ensure no Maintenance modems are migrated to this server. [D above]
QUESTION 86
You have a newly set up 2 node cluster with HA and DRS enabled with DRS in fully automated mode. While testing DRS, you notice no virtual machines are moving from one ESX host to any other despite great disparity in resource utilization between the ESX hosts. Based on the information shown in the exhibit, what is the best solution for this problem?
A.Enable the VMkernel port for VMotion.
B.Remove the uplink used by the VMkernel port group and connect the proper uplink.
C.Disable HA for this cluster.
D.Change the IP address to 10.0.0.204 for the VMkernel interface.
E.No conclusions can be drawn from the exhibit.
Answer: E
Explanation:
A VMkernel port needs to be enabled for VMotion.
Question 83 & 86 are same but there is no exhibit… 🙁
