    • 1. Virtual hardware changes
    • 2. Various virtual machine options
    • 3. Resources settings/allocations. CPU, Memory etc...
  6. Hot-Pluggable Devices

    When adding hardware to a virtual machine, what is the list of devices that are allowed/available to be added dependent on?
    The list of devices that you are allowed to add depends on whether the virtual machine is powered on or powered off.
  7. Hot-Pluggable Devices

    Name/list 3 hardware device types the are hot-pluggable enabled by default.
    • 1. USB controllers
    • 2. Ethernet adapters
    • 3. hard disks
  8. Hot-Pluggable Devices

    CPU and Memory can not be added while a virtual machine is powered on. True or False?

    If False, Why?
    False. CPU and Memory can be added while a virtual machine is powered on. This feature is called the CPU hot-plug and memory hot-add option. These options are disabled by default.
  9. Hot-Pluggable Devices

    The CPU hot-plug and Memory hot-add features are enabled by default. True or False?

    If False, Why?
    False. These options are disabled by default. To use these hot-plug features:

    • VMware Tools must be installed
    • Virtual machine version must be 7 or higher
    • The VM guest OS must support CPU and memory hot-plug functionality.
    • The hot-plug options must be enabled in the Options tab of the VM properties dialog box.
  10. Hot-Pluggable Devices

    Name/list 4 requirements to use the CPU hot-plug and Memory hot-add features option.
    • VMware Tools must be installed.
    • Virtual machine version must be 7 or higher.
    • The VM guest OS must support CPU and memory hot-plug functionality.
    • The hot-plug options must be enabled in the Options tab of the VM properties dialog box.
  11. Dynamically Increasing a Virutal Disk's Size

    You can increase the size of a virtual disk that belongs to a vitual machine that is powered on. True or False?

    If False, Why?
    True.
  12. Dynamically Increasing a Virutal Disk's Size

    You can increase the size of a virtual disk belonging to a virtual machine if it is a ____ virtual disk in ____ mode and the virtual machine does not have ____.
    You can increase the size of a virtual disk belonging to a virtual machine if it is a flat virtual disk in persistent mode and the virtual machine does not have snapshots.
  13. Dynamically Increasing a Virutal Disk's Size

    What are the steps to increase the size of a virtual disk?
    • 1. Right-click the virtual machine in the inventory and click Edit Settings.
    • 2. Select the hard disk in the Hardware list.
    • 3. In the Disk Provisioning panel, enter the new size for the hard disk.

    After you increase the size of a virtual disk, use the appropiate tool in the guest operating system itself to allow the file system on the disk to use the newly allocated disk space. e.g. Diskpart utility, Windows Disk Management
  14. Creating an RDM

    What is a RDM?
    A raw device mapping (RDM) is a file on a VMware vStorage VMFS datastore with a .vmdk extension (the file contains only disk information describing the mapping to a LUN) that points to a raw LUN.
  15. Creating an RDM

    What happens when you create a raw device mapping?
    When you create a raw device mapping, vCenter Server creates a file in the specified VMFS volume that points to a raw LUN.
  16. Creating an RDM

    What does encapsulating disk information in a RDM allow?
    Encapsulating disk information in the file (RDM) allows the VMkernel to lock the LUN so that only one virtual machine can write to it.
  17. Creating an RDM

    Where is the data for an RDM stored?
    The data is stored on the LUN.
  18. Creating an RDM

    How many compatibility modes does an RDM support and what are they?
    An RDM supports two compatibility modes:

    • 1. Physical compatibility mode.
    • 2. Virtual compatibility mode.
  19. Creating an RDM

    What does RDM Physical compatibility mode allow?
    RDM Physical compatibility mode allows the guest operating system to access the hardware directly.
  20. Creating an RDM

    Physical compatiblity is useful if you are using SAN-aware applications in the virtual machine. True or False?

    If False, Why?
    True.
  21. Creating an RDM

    A LUN configured for physical compatibility mode can be cloned, made into a template or migrated using storage vMotion. True or False?

    If False, Why?
    False. The inability to take a native Vmware snapshot of a pRDM also means that features that depend on Vmware snapshots (the vStorage API’s for Data Protection, Vmware Data Recovery, and Storage vMotion) don’t work with pRDMs. With Physical compatibility mode a VM can access a LUN directly. This is generally used when the application inside VM wants to directly access LUN. However when using physical compatibility mode you lose the option to clone a VM, make it a template or migrate it if it involves copying the disk.
  22. Creating an RDM

    What does RDM Virtual compatibility mode allow?
    Virtual compatibility mode allows a RDM LUN to behave as if it were a virtual disk and therefore allows the virtual machine to use VMware shapshots and other storage advanced functionality e.g. storage VMotion.
  23. Creating an RDM

    When using RDM virtual compatibility mode, when are the contents of the LUN copied to a virtual disk (.vmdk) file?
    When you clone the disk, make a template out of it, or migrate it (if the migration involves copying the disk).
  24. Virtual Machine Options

    In the virtual machine's General Options pane, what two options/settings can be modified?
    • 1. VM display name
    • 2. Guest operating system type
  25. Virtual Machine Options

    In the virtual machine's General Options pane, what two options/settings can not be modified?
    • 1. .vmx file - VM configuration file
    • 2. VM directory - VM working location
  26. Virtual Machine Options

    Changing a virtual machine's display name will change the names of all the virtual machine files and the directory the virtual machine is stored in. True or False?

    If False, Why?
    False. When a virtual machine is first created, the file names and the directory name associated with the VM are based on its display name. But changing the display name later does not modify the file and directory names.
  27. Virtual Machine Options

    Name\list the 4 options/settings in the virtual machines options tab General Options pane.
    • 1. Virtual Machine Name
    • 2. Virutal Machine Configuration File
    • 3. Virtual Machine Working Location

    • 2. Linux
    • 3. Novell Netware
    • 4. Solaris
    • 5. Other
  29. Virtual Machine Options

    What are the two settings that can be modified/changed in the virtual machines options tab General Options pane.
    • 1. Display name
    • 2. Guest operating system type
  30. Virtual Machine Options

    Changing the display name will change the name of all of the virtual machine files and the directory the virtual machine is stored in. True or False?

    If False, Why?
    False. When a virtual machine is first created, the file names and the directory name associated with the virtual machine are based on its display name. But changing the display name later does not modify the file and directory names.
  31. Options: VMware Tools

    Name\list the 3 settings panels/sections in the virtual machines options tab VMware Tools pane.
    • 1. Power Controls
    • 2. Run VMware Tools Scripts
    • 3. Advanced
