Kubernetes and Google Kubernetes Engine are used to manage containers in this section of the course.
Learning Objectives:
- Explain what a container is and its applications.
- Describe Kubernetes and Google Kubernetes Engine and their respective use cases.
- Understand hybrid and multi-cloud computing with Anthos.
CONTAINERS IN THE CLOUD
1. Select two reasons for using containers to deploy applications. (Choose 2 responses.)
- It creates consistency across development, testing, and production environments. (Correct)
- It provides tight coupling between applications and operating systems.
- Allocating resources in which to run containers is not necessary.
- Migrating workloads is simpler. (Correct)
2. How do containers access an operating system?
- Each container has its own instance of an operating system.
- Containers use a shared base operating system stored in a shared kernel layer. (Correct)
- Containers use a shared base operating system stored in a Cloud Storage bucket.
- Containers use a shared base operating system stored in a shared runtime layer.
3. What is a Kubernetes pod?
- A group of VMs
- A group of containers (Correct)
- A group of clusters
- A group of nodes
4. What is a Kubernetes cluster?
- A group of containers that provide high availability for applications.
- A group of machines where Kubernetes can schedule workloads. (Correct)
- A group of pods that manage the administration of a Kubernetes application.
5. Where do the resources used to build Google Kubernetes Engine clusters come from?
- Compute Engine (Correct)
- Cloud Storage
- Bare metal servers
- App Engine
6. How do you keep your Kubernetes version updated in Google Kubernetes Engine?
- The Google Kubernetes Engine team periodically performs automatic upgrades of your cluster to newer stable versions. (Correct)
- You need to stop your cluster and manually update the Kubernetes version in your cluster.
- You are required to set up a cron job to periodically check the Kubernetes version in your cluster.
- You cannot update a running cluster. You need to create a copy of the cluster with the updated Kubernetes version.
7. Anthos provides a rich set of tools for monitoring and maintaining the consistency of your applications across which of the following locations?
- Applications hosted on-premises only.
- Applications hosted with one cloud provider only.
- Applications hosted with multiple cloud providers only.
- Applications hosted on-premises, in the cloud, or in multiple clouds. (Correct)
