AZ-104: Microsoft Azure Administrator Full Course - Availability Sets

The video tutorial explains the importance of redundancy in server design, focusing on Microsoft Azure availability sets. It highlights how these sets prevent single points of failure by distributing virtual machines across multiple physical servers. The tutorial also covers the setup and functionality of availability sets, emphasizing the need for identical functionalities and software. Finally, it provides guidelines for building reliable cloud solutions, including configuring multiple virtual machines and using managed disks.

What is the primary purpose of having multiple servers in a design?

• To reduce the cost of hardware

• To handle business requests if one server fails

• To increase the speed of processing

• To simplify the network architecture

What does an Azure availability set ensure for virtual machines?

• They are all upgraded simultaneously

• They run on a single physical server

• They are not affected by a single point of failure

• They have different software installed

How does Azure availability sets help maintain application uptime?

• By ensuring only a subset of virtual machines are impacted during failures

• By using unmanaged disks

• By upgrading all virtual machines at once

• By running all virtual machines on the same server

What should be configured into separate availability sets?

• All virtual machines together

• Only the database servers

• Only the web servers

• Each application tier

Which component should be combined with availability sets for better redundancy?

• A database

• A VPN

• A load balancer

• A firewall
