AZ-104: Microsoft Azure Administrator Full Course - What are Containers?

The video tutorial explains the differences between virtual machines and containers, highlighting their respective roles in software deployment. Virtual machines virtualize hardware, while containers virtualize the operating system, making them more portable and efficient. Containers, managed by applications like Docker, allow multiple applications to run on the same machine with shared OS kernels, offering resource isolation and efficient use of space. The tutorial also discusses the benefits of using both technologies together for flexible application deployment and management.

What is the primary difference between containers and virtual machines?

• Containers virtualize the hardware, while virtual machines virtualize the operating system.

• Containers virtualize the operating system, while virtual machines virtualize the hardware.

• Containers and virtual machines both virtualize the hardware.

• Containers and virtual machines both virtualize the operating system.

Which application is commonly used to manage multiple containers?

• Hypervisor

• VirtualBox

• Docker

• VMware

How do containers maintain isolation when running on the same virtual machine?

• By using separate physical hardware

• By sharing the same operating system kernel

• By managing dependencies within each container

• By using different hypervisors

What is a key advantage of containers over virtual machines in terms of resource usage?

• Containers are slower to boot than virtual machines.

• Containers require more space than virtual machines.

• Containers take less space and are quicker to boot.

• Containers include a full copy of the operating system.

Why are containers considered more portable than virtual machines?

• They include a full copy of the operating system.

• They can run on any hardware without modification.

• They package the application code and dependencies together.

• They require a separate operating system for each application.
