AZ-104: Microsoft Azure Administrator Full Course - Containers Versus Virtual Machines

The video tutorial explores the concept of virtualization, focusing on containers and virtual machines. It explains how containers allow multiple applications to run within the same OS instance, providing lightweight isolation compared to virtual machines, which offer complete isolation. The tutorial covers the differences in resource usage, deployment methods, and storage solutions for both technologies. It also discusses redundancy and fault tolerance, highlighting the advantages of containers in certain use cases.

What is a key difference between containers and virtual machines in terms of isolation?

• Virtual machines can only run one application at a time.

• Containers provide stronger security boundaries than virtual machines.

• Virtual machines provide complete isolation from the host operating system.

• Containers require more system resources than virtual machines.

Which tool is commonly used to deploy individual containers?

• Hyper V

• Windows Admin Center

• Docker command lines

• System Center virtual machine manager

What storage option is used for local storage of a single node in Azure containers?

• SMB file share

• Virtual hard disk

• Azure disks

• Azure files

How do containers handle a cluster node failure?

• Containers require a complete system reboot.

• Containers are rapidly recreated by the orchestration service.

• Containers are manually restarted by an administrator.

• Containers failover to another server in a cluster.

What is a significant advantage of container services over physical and virtual machines?

• They offer less flexibility in application deployment.

• They are more difficult to manage.

• They require more system resources.

• They provide significant advantages in redundancy and resilience.
