Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q92-Q97):

NEW QUESTION # 92
Which of the following values are valid in thefirmwareattribute of a<os>element in a libvirt domain definition? (Choose two.)

Answer: B,E


NEW QUESTION # 93
Which of the following resources can be limited by libvirt for a KVM domain? (Choose two.)

Answer: A,C


NEW QUESTION # 94
Which of the following statements are true about container-based virtualization? (Choose two.)

Answer: B,E

Explanation:
Explanation
Container-based virtualization is a method of operating system-level virtualization that allows multiple isolated user spaces (containers) to run on the same host system1. Each container shares the same operating system kernel as the host, but has its own file system, libraries, and processes2. Therefore, the statements A and C are false, as containers do not run their own kernels or rely on hardware support from the CPU. The statement E is also false, as Linux does support container-based virtualization through various technologies, such as cgroups, namespaces, LXC, Docker, etc12. The statement B is true, as different containers may use different distributions of the same operating system, such as Debian, Ubuntu, Fedora, etc., as long as they are compatible with the host kernel3. The statement D is also true, as all containers run within the operating system kernel of the host system, which provides isolation and resource management for them12. References:

NEW QUESTION # 95
In an IaaS cloud, what is a common method for provisioning new computing instances with an operating system and software?

Answer: A

Explanation:
In an IaaS cloud, the most common method for provisioning new computing instances is to use an image file that contains a pre-installed operating system and software. This image file is also known as a machine image, a virtual appliance, or a template. The image file can be customized for a specific purpose, such as a web server, a database server, or a development environment. The image file can be stored in a repository or a library that is accessible by the cloud provider or the user. When a new instance is requested, the cloud provider copies the image file to a virtual disk and attaches it to the instance. The instance then boots from the virtual disk and runs the operating system and software from the image file. This method is faster and more efficient than installing the operating system and software from scratch for each new instance. It also ensures consistency and reliability across multiple instances that use the same image file. References:

NEW QUESTION # 96
FILL BLANK
What LXC command starts a new process within a running LXC container? (Specify ONLY the command without any path or parameters.)

Answer:

Explanation:
lxc-attach
Explanation
The lxc-attach command allows the user to start a new process within a running LXC container12. It takes the name of the container as an argument and optionally a command to execute inside the container. If no command is specified, it creates a new shell inside the container1. For example, to list all the files in the home directory of a container named myContainer, one can use:
lxc-attach -n myContainer - ls -lh /home
