• Question 43:

  An administrator is upgrading an ESXi 5.5 host to ESXi 6.x and gets the following error:

  MEMORY_SIZE

  What does this indicate?

  A. Insufficient memory on the ESXi host to complete the upgrade.
  B. Insufficient memory for Auto Deploy to complete the upgrade.
  C. Insufficient memory in vCenter Server to complete the upgrade.
  D. Insufficient memory for Update Manager to complete the upgrade.
  A. Insufficient memory on the ESXi host to complete the upgrade.

  A-) ESXi 6.0 requires the NX/XD bit to be enabled for the CPU in the BIOS.

  ESXi requires a minimum of 4GB of physical RAM. It is recommended to provide at least 8 GB of RAM to run virtual machines in typical production environments.

  To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on x64 CPUs.

• Question 45:

  An administrator wants to reduce the memory overhead for a 3D graphics enabled virtual machine (VM).

  What advanced feature can be added to the VM configuration file to reduce memory overhead?

  A. vga.vgaOnly=TRUE
  B. vga.svgaEnable=FALSE
  C. svgaEnabled=FALSE
  D. svgaDisable=TRUE
  A. vga.vgaOnly=TRUE

  Reduce Memory Overhead for Virtual machines with 3D graphics Option

  Virtual machines with the 3D graphics option enabled can have higher memory consumption than other virtual machines. You can reduce the memory overhead by editing the configuration file (.vmx file) of your virtual machines and disabling

  certain memory related settings. Reducing the memory overhead of virtual machines can help you increase the number of virtual machines per host.

  Prerequisites

  Verify that your virtual machines are using hardware version 10 or later.

  Procedure

  1 Shut down the virtual machine on which the 3D graphics option is enabled.

  2 Disable the Accelerate 3D Graphics option.

  3 Upgrade your ESXi host to use the features available in hardware version 10 or later.

  4 Set the maximum size of your display to the size you need.

  5 Locate the configuration file (.vmx) of your virtual machine.

  6 Open the virtual machine configuration file in a text editor and add the line, vga.vgaOnly=TRUE.

  This option removes all graphics and SVGA functionality from your SVGA device, but does not remove the settings that allow BIOS to enter VGA mode.

  7 Save the changes and exit the text editor.

  8 Power on your virtual machine and check the display console.

  9 Verify the memory reservation settings in the vmware.log file.

• Question 47:

  Which two identification sources can a vSphere Auto Deploy rule use to identify target hosts? (Choose two.)

  A. Processor Serial Number
  B. Security Identifier
  C. SMBIOS information
  D. BIOS UUID
  C. SMBIOS information
  D. BIOS UUID

  ---

  You specify the behavior of the Auto Deploy server by using a set of rules written in Power CLI. The Auto Deploy rule engine checks the rule set for matching host patterns to decide which items (image profile, host profile, or vCenter Server location) to provision each host with. The rule engine maps software and configuration settings to hosts based on the attributes of the host. For example, you can deploy image profiles or host profiles to two clusters of hosts by writing two rules, each matching on the network address of one cluster The rule engine includes rules and rule sets.

  Rules Rules can assign image profiles and host profiles to a set of hosts, or specify the location (folder or cluster) of a host on the target vCenter Server system. A rule can identify target hosts by boot MAC address, SMBIOS information, BIOS UUID, Vendor, Model, or fixed DHCP IP address. In most cases, rules apply to multiple hosts. You create rules by using Auto Deploy PowerCLI cmdlets. After you create a rule, you must add it to a rule set. Only two rule sets, the active rule set and the working rule set, are supported. A rule can belong to both sets, the default, or only to the working rule set. After you add a rule to a rule set, you can no longer change the rule. Instead, you copy the rule and replace either items or patterns. By default, Auto Deploy uses the name of the rule for the copy and hides the original rule.

• Question 49:

  B and D

  As per exhibit Rule settings:

  VM-Host Affinity Rules

  A VM-Host affinity rule specifies whether or not the members of a selected virtual machine DRS group can run on the members of a specific host DRS group. Unlike a VM-VM affinity rule, which specifies affinity (or anti-affinity) between

  individual virtual machines, a VM-Host affinity rule specifies an affinity relationship between a group of virtual machines and a group of hosts. There are 'required' rules (designated by "must") and 'preferential' rules (designated by "should".)

  A VM-Host affinity rule includes the following components.

  One virtual machine DRS group.

  One host DRS group.

  A designation of whether the rule is a requirement ("must") or a preference ("should") and whether it is affinity ("run on") or anti-affinity ("not run on"). Because VM-Host affinity rules are cluster-based, the virtual machines and hosts that are

  included in a rule must all reside in the same cluster. If a virtual machine is removed from the cluster, it loses its DRS group affiliation, even if it is later returned to the cluster.
