What is Kubernetes commonly used for?

Question

Options

• ATo develop web applications directly
• BTo create virtual machines
• CTo manage operating systems
• DTo manage application deployment and scaling

• A
  2% (1)
• B
  7% (4)
• C
  3% (2)
• D
  89% (54)

Explanation

D is correct because Kubernetes is an open-source container orchestration platform designed specifically to automate deploying, scaling, and managing containerized applications across clusters of machines.

Why the distractors are wrong:

• A - Kubernetes doesn't write or develop applications; it runs them after they're built.
• B - Kubernetes manages containers (like Docker), not virtual machines; that's the domain of tools like VMware or Hyper-V.
• C - Operating system management belongs to tools like Ansible, Chef, or Puppet - Kubernetes sits above the OS layer.

Memory tip: Think of Kubernetes (K8s) as a traffic controller for containers - it decides where apps run, restarts them when they crash, and scales them up when traffic spikes. "Deploy and scale" = Kubernetes.
