  • True
  • False

Q2) Containers are loosely coupled to their environments. What does that mean? Choose all the statements that are true. (3 correct answers)

  • Deploying a containerized application consumes less resources and is less error-prone than deploying an application in virtual machines.
  • Containers are easy to move around.
  • Containers package your application into equally sized components.
  • Containers don’t require any particular runtime binary.
  • Containers abstract away unimportant details of their environments.

Kubernetes

Q1) What is a Kubernetes Pod?

  • A group of nodes
  • A group of clusters
  • A group of containers

Q2) What is a Kubernetes cluster?

  • A group of machines where Kubernetes can schedule workloads
  • A group of containers that provide high availability for applications

Kubernetes Engine

Q1) Where do the resources used to build Kubernetes Engine clusters come from?

  • Bare-metal servers
  • Compute Engine
  • App Engine

Q2) True or false: Google keeps Kubernetes Engine refreshed with successive versions of Kubernetes.

  • True
  • False

Containers, Kubernetes, and Kubernetes Engine

Q1) Identify two reasons for deploying applications using containers. (Choose 2 responses.)

  • Consistency across development, testing, production environments
  • No need to allocate resources in which to run containers
  • Tight coupling between applications and operating systems
  • Simpler to migrate workloads

Q2) True or False: Kubernetes allows you to manage container clusters in multiple cloud providers.

  • True
  • False

Q3) True or False: Google Cloud Platform provides a secure, high-speed container image storage service for use with Kubernetes Engine.

  • True
  • False

Q4) In Kubernetes, what does “pod” refer to?

  • A group of containers that work together
  • A popular management subsystem
  • A group of clusters that work together
  • A popular logging subsystem

Q5) Does Google Cloud Platform offer its own tool for building containers (other than the ordinary docker command)?

  • Yes; the GCP-provided tool is an option, but customers may choose not use it.
  • No; all customers use the ordinary docker command.
  • Yes. Kubernetes Engine customers must use the GCP-provided tool.

Q6) Where do your Kubernetes Engine workloads run?

  • In clusters implemented using App Engine
  • In clusters built from Compute Engine virtual machines
  • In clusters that are built into GCP, not separately manageable
  • In clusters implemented using Cloud Functions
