Frequently Asked Questions

Which topics in 305-300 typically carry the most exam weight?

Libvirt Virtual Machine Management and Full Virtualization concepts tend to be heavily tested because they form the foundation of Linux-based virtualization infrastructure. Container Virtualization is also significant, reflecting the industry shift toward containerized workloads. Allocate study time proportionally to these areas while ensuring you understand all four domains.

How do Full Virtualization and Container Virtualization differ in practical workflows?

Full Virtualization uses hypervisors to run complete guest operating systems with isolated kernels, making it ideal for legacy applications and multi-tenant isolation. Container Virtualization shares the host kernel and provides lightweight process-level isolation, enabling faster deployment and resource efficiency. Understanding when to use each approach, and how they coexist in modern infrastructure, is critical for the exam.

What hands-on experience is most valuable for preparing for this exam?

Set up a KVM/libvirt lab environment where you practice creating VMs, managing disk images, configuring networking, and taking snapshots. Simultaneously, work with container runtimes like Docker or Podman to understand image management and container networking. Real experience with these tools dramatically improves your ability to answer scenario-based questions and builds confidence in practical decision-making.

What are common mistakes that cause candidates to lose points on 305-300?

Many candidates underestimate libvirt command syntax and configuration details, leading to errors on practical questions. Others confuse container concepts with VM concepts, especially around resource isolation and networking. Additionally, rushing through scenario-based items without carefully analyzing the context often leads to suboptimal solutions. Slow down, re-read questions, and verify your understanding of the specific technology domain before answering.

How should I structure my final week of preparation before the exam?

In the final week, shift focus from learning new content to reinforcing weak areas and building test-taking rhythm. Take two full-length practice tests under timed conditions, review all incorrect answers, and revisit any topics where you scored below 80%. Spend the last 2-3 days doing light review of key commands, configurations, and decision-making frameworks rather than attempting to learn new material.

Question No. 1

What does IaaS stand for?

Show Answer Hide Answer
Correct Answer: E

IaaS is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. IaaS is one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless12. IaaS eliminates the need for enterprises to procure, configure, or manage infrastructure themselves, and they only pay for what they use23. Some examples of IaaS providers are Microsoft Azure, Google Cloud, and Amazon Web Services.

What LXC command starts a new process within a running LXC container? (Specify ONLY the command without any path or parameters.)

Show Answer Hide Answer
Correct Answer: A

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

Question No. 3

How does Packer interact with system images?

Show Answer Hide Answer
Correct Answer: E

Packer is a tool that automates the creation of identical machine images for multiple platforms from a single source configuration. Packer works by creating an instance based on a source image, which is a pre-existing image that serves as a starting point. Packer then connects to the instance through a network connection, such as SSH or WinRM, and runs various commands and scripts to install and configure software within the instance. Packer then shuts down the instance and creates a new system image from it, which can be used to launch new instances. Packer supports many platforms, such as AWS, Azure, VMware, Docker, and others. Packer does not install any software or run any daemon within the target image, nor does it periodically connect to the running instances to re-apply the template. Packer also does not modify the source image directly, but creates a new image from the modified instance. Reference:

Question No. 4

Which of the following commands moves the libvirt domain web1 from the current host system to the host system host2?

Show Answer Hide Answer
Correct Answer: C

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. Reference:

Question No. 5

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

Show Answer Hide Answer
Correct Answer: A, B

Libvirt is a toolkit that provides a common API for managing different virtualization technologies, such as KVM, Xen, LXC, and others. Libvirt allows users to configure and control various aspects of a virtual machine (also called a domain), such as its CPU, memory, disk, network, and other resources. Among the resources that can be limited by libvirt for a KVM domain are:

Amount of CPU time: Libvirt allows users to specify the number of virtual CPUs (vCPUs) that a domain can use, as well as the CPU mode, model, topology, and tuning parameters. Users can also set the CPU shares, quota, and period to control the relative or absolute amount of CPU time that a domain can consume. Additionally, users can pin vCPUs to physical CPUs or NUMA nodes to improve performance and isolation. These settings can be configured in the domain XML file under the <cpu> and <cputune> elements12.

Size of available memory: Libvirt allows users to specify the amount of memory that a domain can use, as well as the memory backing, tuning, and NUMA node parameters. Users can also set the memory hard and soft limits, swap hard limit, and minimum guarantee to control the memory allocation and reclaim policies for a domain. These settings can be configured in the domain XML file under the <memory>, <memoryBacking>, and <memtune> elements13.

The other resources listed in the question are not directly limited by libvirt for a KVM domain. File systems allowed in the domain are determined by the disk and filesystem devices that are attached to the domain, which can be configured in the domain XML file under the <disk> and <filesystem> elements14. Number of running processes and number of available files are determined by the operating system and the file system of the domain, which are not controlled by libvirt.
