Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q82-Q87):

NEW QUESTION # 82
Which of the following components are essential in Docker architecture? (Select all that apply)

Answer: A,B,D

Explanation:
Docker architecture consists of several core components that enable container creation and management.
According to Docker documentation, theDocker Client,Docker Daemon, andDocker Registryare essential components.
TheDocker Clientis the user-facing command-line interface that sends commands to the daemon. TheDocker Daemon (dockerd)performs the heavy lifting, such as building images, running containers, and managing networks and storage. TheDocker Registrystores container images, enabling image distribution and reuse.
Docker Composeis an optional orchestration tool used to define and run multi-container applications, but it is not an essential architectural component.
Therefore, the correct answers areA, C, and D.


NEW QUESTION # 83
What is the purpose ofcloud-init?

Answer: C


NEW QUESTION # 84
Ifdocker stackis to be used to run a Docker Compose file on a Docker Swarm, how are the images referenced in the Docker Compose configuration made available on the Swarm nodes?

Answer: B


NEW QUESTION # 85
Which of the following network interface types are valid in an LXD container configuration? (Choose THREE)

Answer: A,B,E

Explanation:
LXD supports several network interface types that define how containers connect to the host and external networks. According to LXD documentation, valid interface types includephysical,bridged, andmacvlan.
Aphysicalinterface allows a container to be directly connected to a host network interface. Abridgedinterface connects the container to a Linux bridge, enabling communication with other containers and external networks.Macvlanassigns a unique MAC address to the container, making it appear as a separate device on the physical network.
Optionswifandipsecare not valid LXD network interface types. Therefore, the correct answers areC, D, and E.


NEW QUESTION # 86
Which of the following commands moves the libvirt domainweb1from the current host system to the host systemhost2?

Answer: D

Explanation:
Explanation
The correct command to move the libvirt domain web1 from the current host system to the host system host2 is virsh migrate web1 qemu+ssh://host2/system. This command uses the virsh migrate command, which initiates the live migration of a domain to another host1. The first argument is the name of the domain to migrate, which in this case is web1. The second argument is the destination URI, which specifies the connection to the remote host and the hypervisor to use2. In this case, the destination URI is qemu+ssh://host2/system, which means to use the QEMU driver and connect to host2 via SSH, and use the system instance of libvirtd3. The other options are incorrect because they either use invalid commands or arguments, such as node-update, pool-add, patch, or cp, or they do not specify the destination URI correctly.
