Question 1/101/10

Which of the following circumstances prevent the usage of container based virtualization? (Choose
TWO correct answers.)

Select multiple answer: (Choose 2)Select the answer

2 correct answers

More than one container requires access to block devices available in the host system.

Remote access via SSH is required to all containers.

Each container needs to have its own user accounts and user groups.

Administrators of containers must be able to install customized Linux kernels.

Different operating systems are to be used within containers on the same virtualization host.

The correct answers are D and E.
Container-based virtualization isolates applications and their user-space environments, but the containers share the host’s kernel. This means a container cannot load and use its own customized kernel independently of the host.
D. Administrators of containers must be able to install customized Linux kernels.
This is not supported by ordinary container virtualization. A container uses the host’s kernel, so its administrator cannot replace that kernel or run a separate customized one. A virtual machine would be more suitable when each environment needs its own kernel.
E. Different operating systems are to be used within containers on the same virtualization host.
Containers generally need to use a kernel compatible with the host’s kernel. For example, different Linux distributions can often run in containers on a Linux host because they share the Linux kernel, but a Linux container cannot ordinarily run its own Linux kernel on a Windows host, or vice versa. Virtual machines are appropriate when different operating-system kernels are required.
Why the other options do not prevent container use:
A. More than one container requires access to block devices available in the host system.
Containers can be configured to access host block devices. Access must be managed carefully, especially if multiple containers might modify the same device, but this requirement does not inherently rule out containers.
B. Remote access via SSH is required to all containers.
SSH can be installed and configured inside containers. It is not always necessary, since containers are often managed through the host’s container tools, but requiring SSH does not prevent their use.
C. Each container needs to have its own user accounts and user groups.
Containers can have their own user and group information. User namespaces can also map container identities to different identities on the host, providing additional isolation. This requirement does not inherently rule out containers.

Right Answer: D, E

Quiz

Question 2/102/10

When migrating a physical machine to a full virtualized machine, which of the following properties
should be expected to change from the perspective of the guest operating system? (Choose TWO
correct answers.)

Select multiple answer: (Choose 2)Select the answer

2 correct answers

The user accounts within the guest operating system.

The properties of the CPU and other hardware devices.

The MAC address of the network interfaces.

The version of the guest operating system.

Quiz

Question 3/103/10

Which of the following statements are true regarding IaaS computing instances? (Choose TWO
correct answers.)

Select multiple answer: (Choose 2)Select the answer

2 correct answers

Creation of new instances can be automated by using scripts or APIs and service interfaces.

The root file system of a computing instance is always persistent and can be accessed after the instance is destroyed.

Each and every user of an IaaS cloud has exactly one computing instance.

Once created, computing instances are seldom deleted in order to ensure the accessibility of the instance's data.

Instances may be created when needed and destroyed when they become obsolete.

Question 5/105/10

Which of the following statements are true regarding Xen domains? (Choose TWO correct answers.)

Select multiple answer: (Choose 2)Select the answer

2 correct answers

Fully virtualized and paravirtualized domains are managed using the same tools and commands.

Xen domains of all types require virtualization extensions in the host system's CPU.

All fully virtualized domains are called 'Dom0' while all paravirtualized domains are called 'DomU'.

Both paravirtualized and fully virtualized domains may run on the same host system.

Paravirtualized domains are significantly slower than fully virtualized domains.
