Question No : 1
A vApp template recently added to a Content Library is not displayed.
Which two actions could correct this problem? (Choose two.)

正解:
Explanation:
If the vApp template is not displayed in the content library, select the download all library content immediately option and manually synchronize the library. Reference: https://pubs.vmware.com/vsphere-60/index.jsp?topic=% 2Fcom.vmware.vsphere.vm_admin.doc%2FGUID-F7BF0E6B-7C4F-4E46-8BBF-76229AEA7220.html

Question No : 2
An administrator wants to deploy a vApp and dynamically assign IP addresses without a DHCP server on the network.
Which action would you take to accomplish this task?

正解:
Explanation:
IP pools were first introduced with vSphere 4, but they’re not necessarily used by everyone. IP pools are necessary if you want create or deploy a vApp. They provide a network identity to vApps. IP pool gives a network config to VMs that run in the vApp. So you’ll also need to have an IP pool configured if you want to test vCloud Automation Center (VCAC) or Horizon Workspace.
When you configure an IP Pool you specify a range of either IPv4 or IPv6 addresses, DNS and proxy settings, and select which vSwitch port groups that the pool will be available to. Usually you’ll want to do a static IP for server VMs, but you might want to have a test VLAN for developments and you need DHCP there.

Question No : 3
A vApp is running out of compute resources when overall activity is high within the resource pool. At other times, everything is fine.
What should be done to resolve this issue?

正解:
Explanation:
For the problem, set the vApp CPU and memory reservation type to expandable. Reference: https://pubs.vmware.com/vsphere-50/index.jsp?topic=% 2Fcom.vmware.vsphere.vm_admin.doc_50%2FGUID-9902FD4C-4727-43F7-AEAF-901DA4CB4D60.html

Question No : 4
An administrator has a virtual machine that requires four times the compute resources than other virtual machines on the same ESXi 6.x host.
How should the administrator configure the virtual machine settings, in order to be prepared for any resource contention?

正解:
Explanation:
For the virtual machine that requires more resources, you can set the shares of the priority VM to high and set the rest to medium or low. Reference: http://www.globalknowledge.net/mea-shared-content/documents/645372/645389/ WP_VM_Resource_Pools.pdf (page 3)

Question No : 5
Which two options would allow a database administrator, with no access to the vSphere infrastructure, to connect to a virtual machine? (Choose two.)

正解:
Explanation:
Accessing a virtual machine with no access to vSphere environment is tricky. You can use virtual machine remote console to remotely access the VM by asking the admin to grant permission to access the console through vcenter server. Reference: http://blog.mwpreston.net/2011/11/25/access-to-vm-console-without-vi-client/

Question No : 6
What is required when changing a virtual machine name using the vSphere Web Client?

正解:
Explanation:
Before changing the name, verify connectivity to ESXi host where the virtual machine resides and that its inventory list is accessible. Reference: https://kb.vmware.com/selfservice/microsites/search.do? language=en_US&cmd=displayKC&externalId=1003742

Question No : 7
A virtual machine has been renamed and an administrator is unable to find files with the new virtual machine name in the datastore.
What is the reason for this?

正解:
Explanation:
The reason is that the names of the files on the datastore do not change that is why admin is unable to find files with new virtual machines name in the datastore. Reference: https://kb.vmware.com/selfservice/microsites/search.do? language=en_US&cmd=displayKC&externalId=1029513

Question No : 8
An administrator is virtualizing a physical application server and adding it to an existing multi-tiered vApp. The application license is currently tied to the physical NIC's MAC address, so the administrator needs to ensure the license will function properly in the virtual machine.
Which two actions can the administrator take to satisfy this task? (Choose two.)

正解:
Explanation:
First set the MAC address for the vNIC in the guest operating system and install the physical server’s NIC into the ESXi host. Reference: http://rickardandersson.com/manual-mac-address-for-a-vmware-guest

Question No : 9
An administrator is cloning and configuring five new web server virtual machines.
What would be the benefit of configuring resource shares for the new VMs?

正解:
Explanation:
Configuring resource shares for the new Vms can prioritize access to a resource during contention Reference: http://www.settlersoman.com/vmware-vsphere-basics-understanding-resource-pools/

Question No : 10
A vApp named Sales has a Memory Limit of 32 GB and a CPU Limit of 12,000 MHz.
There are three virtual machines within the vApp:
- Sales-DB -- Has a memory reservation of 20 GB.
- Sales-DC -- Has a memory reservation of 8 GB.
- Sales-Web -- Has a memory reservation of 8 GB.
Which statement is correct?

正解:
Explanation:
As per the scenario, only two of the three virtual machines can power on.

Question No : 11
A virtual machine template is accidently removed from the vCenter Server Inventory.
Which method would be used to recover the template back into the environment?

正解:
Explanation:
Templates are associated with hosts, and the only way to regain or register templates after removing and adding a host is to use the datastore browser to locate the template. Then use the inventory wizard to name and register the .vmtx file as a template back into vCenter Server. Reference: https://pubs.vmware.com/vsphere-4-esx-vcenter/index.jsp?topic=/ com.vmware.vsphere.bsa.doc_40/vc_admin_guide/working_with_templates_and_clones/ t_regain_templates.html

Question No : 12
An administrator needs to add an object to an existing vApp using the vSphere Web Client.
How is this accomplished?

正解:
Explanation:
to add an object to an existing vApp using the vsphere web client, create an object inside vApp or you can add an object to a vApp. Reference: https://pubs.vmware.com/vsphere-50/index.jsp?topic=% 2Fcom.vmware.vsphere.vm_admin.doc_50%2FGUID-12FDA1A4-6214-463B-8D73-FE25454C642E.html

Question No : 13
When modifying a vApp, which two vSphere entities can be added? (Choose two.)

正解:
Explanation:
A resource pool and a network pool can be added when modifying a vApp. Reference: http://wahlnetwork.com/2012/02/01/understanding-resource-pools-in-vmware-vsphere/

Question No : 14
A new vApp was built and tested in the corporate headquarters datacenter running vSphere 6.x.
What condition would explain why the virtual machine is failing to boot in an offsite datacenter running on vSphere 5.5?

正解:
Explanation:
The virtual machine is failing to boot in an offsite datacenter running on vSphere 5.5 because VM was built with the default hardware version. Reference: https://kb.vmware.com/selfservice/microsites/search.do? language=en_US&cmd=displayKC&externalId=1010675

Question No : 15
Which two configurable options apply to both virtual machine CPU and memory allocation? (Choose two.)

正解:
Explanation:
Reservation and shares apply to virtual machine CPU and memory allocation. Reference: http://frankdenneman.nl/2010/06/08/reservations-and-cpu-scheduling/
