How does containerization differ from traditional virtualization?

Containers are less portable than virtual machines.

Containers share the host OS kernel, while virtual machines each run their own operating system.

Containers require a hypervisor, while virtual machines do not.

Virtual machines are lighter weight than containers.

Which benefit is directly associated with using containers in cloud environments?

Containers always use fewer resources than any virtual machine.

Elimination of the need for configuration management.

Guaranteed security isolation from the host and other containers.

Reduced overhead because containers share the host OS kernel.

A company runs a batch processing job that takes 30 minutes to complete. The job is stateless and can be run in parallel. They currently run this job on a single large VM, which is idle most of the day. They want to reduce infrastructure costs while maintaining the ability to run the job on demand. Which approach is most suitable?

Schedule the job to run only during off-peak hours on the existing VM.

Keep the VM running but resize it to a smaller size.

Run the job as a containerized workload on a serverless container platform.

Move the job to a dedicated physical server in a colocation facility.

A software company wants to provide a consistent development environment for all developers, regardless of their local operating system. They want to avoid the 'it works on my machine' problem. Which approach is most effective?

Use containerization to package the application and its dependencies into a development container image.

Provide developers with a detailed setup guide for each operating system.

Require all developers to use the same physical hardware.

Use a VM image that developers must manually configure.

An organization is running a stateful database in a container on a single node. They want to ensure high availability and automatic failover if the node fails. What is the most appropriate action?

Deploy the database on a VM instead of a container for better reliability.

Use an orchestrator to manage the database as a StatefulSet with persistent volumes and replicas.

Create a snapshot of the container and store it in object storage.

Run the database in a container with a restart policy set to 'always'.
