What OpenShift object enables parameterized deployment of multiple resource sets?

• A. Deployment
• B. ConfigMap
• C. Template
• D. Route

Answer: (C)

Parameterized deployment of multiple resources is achieved with a Template. OpenShift Templates bundle a group of objects (such as Deployments, Services, Routes, ConfigMaps, etc.) and allow you to define parameters that you supply at instantiation time. By processing the template (for example with oc process -p key=value and then applying it), OpenShift renders the parameter values and creates a set of resources customized for that instance. This lets you reuse the same template to spin up different environments or configurations without editing each resource individually. The other options aren’t designed for this purpose. A Deployment manages a set of pods for a single application component, not a collection of resources parameterized together. A ConfigMap stores configuration data, but it doesn’t orchestrate multiple resources or parameterization. A Route exposes a service to the outside world, which is about networking exposure rather than deploying or parameterizing a set of resources.
