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?

• A.Enable IP pools.
• B.Configure a local DHCP server in the vApp.
• C.Enable NAT on the vApp router.
• D.Configure the guest OS for workgroup and WIN

答えを確認する

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

• A.Use the Virtual Machine Remote Console (VMRC).
• B.Use Remote Desktop Protocol (RDP) to connect.
• C.Ask the administrator to grant permission to access the console through vCenter Server.
• D.Ask the administrator to grant permission to access with the Horizon View Direct Connect Client.

答えを確認する
