QUESTION 212
LEAD2PASS Anvil Incorporated has several departments which each have unique resource requirements in their environment.
1. The Manufacturing department has ten production virtual machines.
2. The Development department has two test/dev virtual machines.
3. The Manufacturing virtual machines have only CPU reservations.
4. No Development virtual machine should be able to use more resources than any Manufacturing virtual machine requests.
5. Manufacturing department virtual machines must always be able to power on.
Resource Pools will be used to address these requirements.
When creating the “Manufacturing” and “Development” pools, which settings should be part of the configuration to meet the stated requirements? (Choose two.)
A. Enable Expandable Reservation on Memory Resources on the Manufacturing pool
B. Set a reservation for CPU Resources on the Manufacturing resource pool
C. Create a required Group Rule to ensure Development virtual machines always run on the Development host
D. Ensure the shares set on the Manufacturing pool are at least five times the shares set on the Development pool
Answer: BD
Explanation:
To meet the requirements, set a reservation for CPU resources on the manufacturing resource pool. You also need to make sure the shares set on the Manufacturing pool are at least 5 times the shares set on Development pool since they are required to be powered on always.
QUESTION 213
Click the Exhibit button. An administrator is creating a vApp for a multi-tiered web application. The vApp has been configured as shown in the exhibit. Testing of the vApp indicates that attempts to communicate with the web server on Dev_Web_01 fail. The developer wants to be sure the database server OS is completely started before the other servers power on. The developer also wants to minimize recovery time.

What changes to the vApp configuration will correct the issues?
A. Move the Dev_Web_01 virtual machine to Group 3 and increase the time value
B. Move the Dev_App_01 virtual machine to Group 1 and increase the time value
C. Move the Dev_Web_01 virtual machine to Group 3, decrease the time value and check VMware
Tools are ready
D. Move the Dev_Web_01 virtual machine to Group 3, increase the time value and check VMware
Tools are ready
Answer: D
Explanation:
By setting it up like D, the Web server is started first, then 120 seconds later SQL, and 120 seconds after that App. By selecting A, it will only affect when Dev_App_01 starts…either 120
seconds or when VMware Tools is ready which would only start the VM even sooner once it detects VMware tools on the first two servers…if VMware tools is even installed on them.
QUESTION 214
Click the Exhibit button. Several virtual machines residing in the Production pool are exhibiting poor performance, and a critical virtual machine in the pool appears hung. What step can be taken to increase the performance of the critical virtual machine?

A. Increase the CPU limit on the critical virtual machine.
B. Increase the CPU shares on the critical virtual machine.
C. Increase the CPU reservations on the resource pool.
D. Increase the CPU limit on the resource pool.
Answer: D
Explanation:
It seems the CPU limit is the culprit. Increase the CPU limit on the resource pool.
QUESTION 215
An administrator notices that when a virtual machine is placed into a resource pool, a warning indicates that the virtual machine will receive a very large percentage of the total shares for memory. Which action can be taken to resolve this problem?
A. Increase the memory resource allocation to the resource pool.
B. Increase the share value for the resource pool.
C. Change the shares setting from custom to high, medium, or low for the virtual machine.
D. Decrease the memory allocation for the virtual machine.
Answer: C
Explanation:
The Memory Resources panel lets you allocate memory resources for a virtual machine and specify reservations, limits, and shares. Symbolic values Low, Normal, High, and Custom are compared to the sum of all shares of all virtual machines on the server and, on an ESX host, the service console. By decreasing the memory share of a particular system, it receives less memory out of the total available memory.
QUESTION 216
An administrator views the Fault Tolerance pane of the Summary tab of a virtual machine and finds that the current status is Not Protected.
What are two vSphere Fault Tolerance states that would cause the virtual machine to not be protected? (Choose two.)
A. Stopped – Fault Tolerance has been stopped on the secondary virtual machine.
B. Need Secondary VM – The primary virtual machine is running without a secondary virtual machine
and is not protected
C. Need Primary VM – The secondary virtual machine is running, and a new primary virtual machine
cannot be generated.
D. Disabled – Fault Tolerance is disabled.

QUESTION 217
Click the Exhibit button. An administrator has deployed a new virtual machine on an ESXi 5.x host. Users are complaining of poor performance on the application running on the virtual machine. Performance tools display the results shown in the exhibit.

Which two tasks might improve the user experience? (Choose two.)
A. Add a vCPU to the virtual machine
B. Remove CPU affinity on the advanced CPU setting of the virtual machine
C. Migrate the virtual machine to another ESXi host
D. Remove the limit on the CPU settings of the virtual machine
Answer: AD
Explanation:
As you can see the CPU usage is 100%. This means the virtual machine is using all the resources. Add a vCPU to get more processing power. You might also need to remove the CPU limit in the CPU settings of the virtual machine.
QUESTION 218
Which two conditions prevent the application of a host profile to an ESXi 5.x host? (Choose two.)
A. The host has multiple profiles attached.
B. The host has not been placed into maintenance mode.
C. The host is running virtual machines.
D. The host is an ESXi host.
Answer: BC
Explanation:
When the host is not placed in maintenance mode and when the host is running virtual machines, you cannot apply host profile to an ESXi host.
QUESTION 219
An administrator is editing the IP allocation policy for a vApp.
Which three options are available? (Choose three.)
A. Automatic
B. Roaming
C. Transient
D. DHCP
E. Fixed

QUESTION 220
LEAD2PASS Junkmail Incorporated has been utilizing templates in their environment. They are running a 10-node ESXi 5.x Cluster and DRS has not been configured. Several virtual machines have been deployed from this template and successfully powered on, but a newly deployed virtual machine will not power on. There appear to be adequate CPU and Memory resources available on the host.
Which three things can be done to allow more virtual machines to be deployed into the cluster from this template? (Choose three.)
A. Select a different datastore for the virtual machine
B. Move the swap file to a different location
C. Deploy the virtual machine to a different host using the same datastore
D. Enable DRS on the cluster to balance the virtual machine load out across hosts
E. Increase the virtual machine memory reservation
Answer: ABE
Explanation:
If you make reservations for your virtual machine’s that are equal to the amount of RAM assigned to them, swapping and page sharing does not occur. You can over commit pretty heavily if you are comfortable with poorer performance. If you do not set reservations, ESX host creates a .vswp file equal to the difference between the amount of physical memory assigned to the virtual machine and the reservation it has. By default, memory reservations are set to 0. If you have a virtual machine with 2GB of memory without a reservation, it creates a 2GB .vswp file when it is powered on. The virtual machine starts using the .vswp file if the server is out of physical RAM. If you set a 1GB reservation, it creates a 1GB .vswp file. The .vswp files are what allows for memory overcommitment.
