Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q110-Q115):

NEW QUESTION # 110
Which of the following technologies is the most important component of IaaS clouds?

Answer: C

Explanation:
The foundational technology ofInfrastructure as a Service (IaaS)isvirtualization. Virtualization enables cloud providers to abstract physical hardware into flexible, on-demand virtual resources such as compute instances, storage, and networks.
All major IaaS platforms rely on virtualization to provide scalability, isolation, elasticity, and multi-tenancy.
Without virtualization, the dynamic provisioning model of IaaS would not be possible.
Therefore, the correct answer isB.


NEW QUESTION # 111
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 # 112
FILL BLANK
What LXC command lists containers sorted by their CPU, block I/O or memory consumption? (Specify ONLY the command without any path or parameters.)

Answer:

Explanation:
lxc-top


NEW QUESTION # 113
Which of the following components are essential in Docker architecture? (Select all that apply)

Answer: B,C,D


NEW QUESTION # 114
Which value must be set in the option builder in the configuration file of a Xen guest domain in order to create a fully virtualized machine instead of a paravirtualized one?

Answer:

Explanation:
builder = "hvm"
Explanation:
In Xen virtualization, guest domains can be created using either paravirtualization (PV) or hardware-assisted full virtualization, also known as HVM (Hardware Virtual Machine). According to official Xen documentation, the builder option in a Xen guest domain configuration file determines the type of virtualization used when creating a virtual machine.
To create a fully virtualized (HVM) guest, the configuration file must explicitly set the value of the builder option to "hvm":
builder = "hvm"
This instructs the Xen toolstack to use hardware-assisted virtualization features provided by the CPU, such as Intel VT-x or AMD-V, allowing unmodified guest operating systems to run. Fully virtualized guests behave like physical machines and can run operating systems that are unaware of Xen.
If the builder option is omitted or set to the default paravirtualized builder, Xen expects a PV-capable kernel, which requires guest operating system modifications. HVM guests, by contrast, rely on device emulation and hardware virtualization support.
Virtualization documentation clearly distinguishes between PV and HVM guests and identifies builder =
"hvm" as the required configuration for full virtualization. This setting is fundamental when deploying operating systems such as Windows or standard Linux distributions without Xen-specific kernels.
Therefore, the correct and documented value is builder = "hvm".
