Which of the following is a typical use case for an application container?

Running a legacy application that requires sysvinit and multiple daemons.

Replacing a virtual machine to host multiple unrelated services with different init systems.

Running a single web server process that can be scaled horizontally.

Providing a full desktop environment with a graphical login manager.

A Kubernetes cluster is running with containerd as the runtime. The administrator wants to add a custom OCI runtime that provides hardware acceleration for GPU workloads. The custom runtime is OCI-compliant. How should the administrator integrate this runtime with containerd?

Configure containerd to use the custom runtime as the default runtime in its configuration file

Use CRI-O instead of containerd to support the custom runtime

Modify the Kubernetes kubelet to use the custom runtime directly

Replace containerd with the custom runtime in the Kubernetes cluster

Which of the following is a key difference between cgroup v1 and cgroup v2?

cgroup v2 uses a unified hierarchy, while cgroup v1 uses separate hierarchies for each resource controller.

cgroup v2 requires systemd, while cgroup v1 does not.

cgroup v2 only supports memory and CPU controllers, while cgroup v1 supports all controllers.

cgroup v1 is the default in all modern Linux distributions, while cgroup v2 is deprecated.
