AZ-104: Microsoft Azure Administrator Full Course - Fault Domain and Update Domain

The video tutorial explains the concepts of fault domains and update domains in Azure. Fault domains are essentially server racks that help distribute virtual machines to minimize the impact of hardware failures. Update domains allow for incremental updates to virtual machines without taking services offline, ensuring continuous availability during planned maintenance. Azure provides mechanisms to manage these domains, enhancing reliability and uptime.

What is the primary purpose of a fault domain in Azure?

• To ensure virtual machines are updated simultaneously

• To distribute virtual machines across different racks to avoid a single point of failure

• To manage network traffic efficiently

• To provide backup for virtual machines

How does Azure ensure that services remain online during updates?

• By using fault domains to manage updates

• By updating all virtual machines at once

• By using update domains to perform incremental updates

• By shutting down services temporarily

What is an update domain in Azure?

• A group of virtual machines that share the same hardware

• A set of virtual machines that can be updated and rebooted together during maintenance

• A backup system for virtual machines

• A network configuration tool
