A systems administrator is tasked with deploying 25 identical virtual machines (VMs) to a hypervisor cluster. Each VM must have a specific server operating system, a pre-configured web server application, and all current security patches. The primary goal is to minimize deployment time and ensure consistency across all VMs.
Which of the following installation methods is the MOST efficient for this task?
The correct answer is Template deployment. This method involves creating a master or "golden" virtual machine with the operating system, applications, and all configurations already installed and set up. This template is then used to rapidly create multiple identical clones, which is the most efficient and consistent way to deploy a large number of identical VMs. An unattended installation automates the OS installation process but typically does not include pre-configured applications, making it less efficient for this scenario. A bare-metal installation is incorrect because it refers to installing an OS directly on physical hardware, not creating VMs. P2V conversion is the process of migrating an existing physical server to a virtual one, which is not applicable to deploying new VMs.
