20+ practice questions focused on VM Deployment And Provisioning — one of the most tested topics on the LPIC-3 Exam 305: Virtualization and Containerization (305-300) (305-300) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start VM Deployment And Provisioning PracticeYou are using Packer to automate a build. You notice the build fails because the 'communicator' cannot connect. Which type of communicator is most suitable for a KVM-based build where SSH is not yet configured?
Explanation: Packer's 'none' communicator does not attempt to connect to the guest at all; it simply runs provisioners locally or relies on the builder's own mechanisms. For a KVM-based build where SSH is not yet configured inside the guest, the 'none' communicator is appropriate because Packer cannot establish an SSH or WinRM session without a running and reachable agent in the guest. This is common when building base images where the guest OS is still being installed or configured.
You are using Packer to build a custom image for KVM. Which HCL2 block is specifically required to define the virtualization parameters like memory and CPU for the builder?
Explanation: The qemuargs block in Packer's QEMU builder allows you to pass arbitrary arguments directly to the QEMU command line, including parameters that control memory (-m) and CPU (-smp). While the QEMU builder has dedicated options like 'memory' and 'cpus' in its configuration, the question specifically asks for the HCL2 block that defines virtualization parameters, and qemuargs is the block that provides low-level control over QEMU's virtualization settings. This makes it the correct choice for specifying memory and CPU when the standard builder options are insufficient or when you need to override defaults.
You are troubleshooting a Packer build that uses the 'shell' provisioner. Which environment variable can you check to see the absolute path to the build directory?
Explanation: Packer exposes several variables, and the working directory is often referenced via internal build identifiers, but 'PACKER_BUILD_NAME' is a standard environment variable provided by Packer.
When configuring cloud-init 'network-config', which format is primarily used to describe network interfaces?
Explanation: cloud-init's network-config uses YAML as its primary format, following the Netplan v2 schema. The YAML structure defines version, ethernets, addresses, gateways, and nameservers in a hierarchical, human-readable way. While cloud-init can consume other formats in some contexts, the network-config payload is canonically YAML.
In a Packer HCL2 file, how do you reference a variable named 'image_name' that was declared in the 'variables' block?
Explanation: In Packer's HCL2 template format, variables declared in the 'variables' block are accessed using the 'var.' prefix, so 'var.image_name' is the correct syntax. This follows HashiCorp Configuration Language (HCL) conventions, where input variables are referenced as 'var.<name>'. The other options represent syntax from legacy JSON templates or shell-style interpolation, which are not valid in HCL2.
