Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q115-Q120):

NEW QUESTION # 115
Which of the following statements are true regarding a Pod in Kubernetes? (Choose two.)

Answer: B,E


NEW QUESTION # 116
Which of the following are valid KVM parameters? (Choose THREE correct answers.)

Answer: B,C,E

Explanation:
KVM usesQEMUas its userspace component, and QEMU supports a variety ofnetwork-based block device backendsthrough the -drive file= parameter. According to QEMU and KVM documentation, valid protocols includeSSH,iSCSI, andHTTP/HTTPS.
OptionBis valid because QEMU supports accessing disk images securely overSSH.
OptionCis valid asiSCSIis a supported storage backend for QEMU block devices.
OptionDis valid because QEMU can boot or attach ISO images overHTTP, commonly used for CD-ROM media in installation scenarios.
OptionAis invalid becauseIMAPis not a supported QEMU block protocol.
OptionEis invalid becausersyncis not supported as a block device transport.
Therefore, the correct answers areB, C, and D.


NEW QUESTION # 117
How do containers share the host OS kernel?

Answer: C

Explanation:
Containers operate bysharing the host operating system's kernelwhile running inisolated user spaces.
According to containerization documentation, Linux kernel features such asnamespaces and cgroupsprovide process isolation, resource control, and security boundaries between containers.
Each container has its own filesystem, process tree, and network stack, but all containers rely on the same underlying kernel. This design makes containers lightweight and efficient compared to virtual machines, which require separate guest kernels.
Options A and D are incorrect because containers do use the host kernel. Option C is incomplete because it does not mention isolation. Therefore, the correct answer isB.


NEW QUESTION # 118
FILL BLANK
Which subcommand ofvirshopens the XML configuration of a virtual network in an editor in order to make changes to that configuration? (Specify ONLY the subcommand without any parameters.)

Answer:

Explanation:
net-edit


NEW QUESTION # 119
Which command within virsh lists the virtual machines that are running on the current host?

Answer: E

Explanation:
Explanation
The command virsh list is used to list all running domains (VMs) on the current host. The command virsh list
--all can be used to list both active and inactive domains. The other options are not valid virsh commands. The command virsh list is a basic command that lists all running domains (VMs). You can also list all configured VMs by adding the --all option. This is useful if you want to see all VMs configured in the target hypervisor that you can use on subsequent commands1. References:
