Question 2

While modifying a disk image within VirtualBox, what mode causes any changes made to the disk image to be lost when the VM is powered down?
A) Normal mode
B) Writethrough mode
C) Shareable mode
D) Immutable mode

Accepted Answer

Immutable mode in VirtualBox means any changes to the disk are stored in a temporary differencing disk. When the VM is powered down, these changes are discarded, effectively making the disk return to its original state upon the next startup.

Question 3

The number of snapshots that can be supported for an individual VM is limited only by the amount of disk space available.

Accepted Answer

The number of snapshots that can be supported for an individual VM is limited only by the amount of disk space available.

Question 4

While modifying a disk image within VirtualBox, what mode allows for multiple virtual machines to share a single disk image at the same time, as well as store the changes unique to each VM?
A) Normal mode
B) Writethrough mode
C) Shareable mode
D) Multi-attach mode

Accepted Answer

Multi-attach mode allows multiple VMs to share a single disk image simultaneously, with each VM's changes stored separately, enabling efficient use of disk space and resources.

Question 5

Use of the Shared Clipboard and Drag'n'Drop features of VirtualBox does not require the installation of Guest Additions tools.

Accepted Answer

The Shared Clipboard and Drag'n'Drop features in VirtualBox require the installation of Guest Additions tools in the guest operating system to work.

Question 6

While modifying a disk image within VirtualBox, what mode causes the state of the disk image to not be saved when a snapshot is created, and not restored when a snapshot is reverted back?
A) Normal mode
B) Writethrough mode
C) Shareable mode
D) Immutable mode

Accepted Answer

Writethrough mode in VirtualBox ensures that any changes made to the disk image are written immediately to the physical disk, but these changes are not saved in snapshots. This means that when a snapshot is created, the state of the disk in writethrough mode is not saved, and when a snapshot is reverted, the state is not restored, maintaining the data as it was written to the physical disk at the time of the write operation.

Question 7

You have finished configuring the Remote Display extension for VirtualBox, and must instruct a user on how to connect to the host. What protocol must the user utilize to communicate using this extension?
A) VNC
B) RDP
C) RAW
D) RMP

Accepted Answer

The Remote Display extension for VirtualBox uses the Remote Desktop Protocol (RDP) to allow users to connect to the host.

Question 8

After copying a virtual machine, you discover that neither the copy or the original virtual machine can reliably communicate with the network using a bridged network connection. What is most likely the issue?
A) Both virtual machines have been assigned the same IP address on the network.
B) The copied virtual machine has the same MAC address as the original VM.
C) The copied virtual machine is using the wrong network adapter type.
D) The original VM's configuration file was corrupt before making the copy attempt.

Accepted Answer

When a virtual machine is copied, the copy retains the MAC address of the original virtual machine. Network devices use MAC addresses to uniquely identify devices on the network. If two devices (in this case, the original and the copied VMs) have the same MAC address, it can lead to network communication issues because the network cannot distinguish between the two devices.

Question 9

A dynamically allocated virtual hard disk file will grow and shrink to meet the needs of the virtual machine.

Accepted Answer

A dynamically allocated virtual hard disk file will grow to meet the needs of the virtual machine but will not shrink automatically when data is deleted.

Question 12

What file extension is used by a VirtualBox Machine Definition file?
A) .vmng
B) .vbox
C) .vcfg
D) .virt

Accepted Answer

VirtualBox uses the .vbox extension for its Virtual Machine Definition files. These files contain the configuration settings of the virtual machine created in VirtualBox.

What keyboard shortcut can be used to send a Ctrl + Alt + Delete sequence to a virtual machine in VirtualBox?
A) Ctrl + Alt + Insert
B) Right Ctrl + Alt + Break
C) Right Ctrl + Del
D) Right Ctrl + Break

Accepted Answer

DIn VirtualBox, the "Right Ctrl + Del" shortcut sends the Ctrl + Alt + Delete sequence to a virtual machine, effectively emulating the "Secure Attention Sequence" of Windows. Additionally, "Right Ctrl + Break" is also recognized as a command in some contexts within VirtualBox, particularly for sending special signals, but the primary and most direct equivalent for Ctrl + Alt + Delete is "Right Ctrl + Del."

Question 15

What is the maximum number of virtual hard disks that can be supported on the SATA controller within VirtualBox?
A) 8
B) 16
C) 30
D) 60

Accepted Answer

VirtualBox supports up to 30 virtual hard disks on the SATA controller. This limitation is due to the architecture of the SATA controller emulation within VirtualBox, which allocates slots for up to 30 devices, including both hard disks and optical drives.

Question 16
