What is a template in VMware vSphere?

A template in VMware vSphere serves as a master copy for provisioning new virtual machines. This means that when you need to create a new virtual machine, you can deploy it from the template, ensuring that the new instance is configured with the exact settings and specifications outlined in the template, such as the operating system, application software, and desired hardware settings.

Using templates offers significant advantages, including streamlining the virtual machine deployment process, maintaining consistency across multiple virtual machines, and saving time in configuring virtual machines individually. When a template is created, it can also be updated without affecting existing virtual machines, allowing for easier management and updates.

The other options describe concepts related to virtualization but do not capture the essence of what a template represents within VMware vSphere. For instance, while a virtual machine configuration that cannot be modified may seem relevant, it mischaracterizes how templates function. Templates are not static; they serve as a dynamic starting point for new virtual machines. Similarly, the notion of a cluster of virtual machines for high availability relates to resource management and failover strategies rather than the provisioning aspect that templates are specifically designed for. Lastly, pooling memory resources is a concept associated with resource allocation techniques, further distancing it from the definition of a template.
