Study Guide - Chap28: Understanding Cloud and Virtualization Concepts

Question 1

Which type of hypervisor template bundles all of the configuration files into a single file for distribution?

• XML
• JSON
• OVA
• OVF
• YAML

Answer 1

OVA

The Open Virtualization Appliance (OVA) file format bundles all of the virtual machine configuration files into a single tar file for distribution, so option C is correct. The Open Virtualization Format (OVF) format defines several separate files for storing configuration values, not a single file, so option D is incorrect. XML, JSON, and YAML are all configuration file formats and not methods to bundle the configuration files, so options A, B, and E are all incorrect.

Question 2

OVA

Answer 2

Open Virtual Appliance: A single compressed file containing a complete virtual machine package including the OVF descriptor, virtual disk files, and metadata for easy distribution and deployment.

Question 3

OVF

Answer 3

Open Virtualization Format: An open standard file format for packaging and distributing virtual machines, consisting of multiple files including XML descriptors and virtual disk images.

Question 4

YAML

Answer 4

YAML Ain’t Markup Language: A human-readable data serialization format commonly used for configuration files, automation scripts, and container orchestration in Linux environments.

Question 5

KVM

Answer 5

Kernel-based Virtual Machine: A Linux kernel module that turns the Linux kernel into a Type-1 hypervisor, allowing you to run multiple virtual machines directly on the host hardware with near-native performance using hardware virtualization extensions.

Question 6

XEN

Answer 6

A Type-1 bare-metal hypervisor that runs directly on server hardware below the operating system, managing multiple guest operating systems (called domains) with strong isolation and security, commonly used in enterprise and cloud environments.
