Domain 3.2: High Availability — AZ-305 Practice Question 36

How to approach this question

Recall the SLA numbers (99.95% vs 99.99%) and the physical fault domain differences (racks vs data centers).

Full Answer

Availability Sets distribute VMs across multiple fault domains (server racks) within a single data center, providing a 99.95% SLA. They protect against localized hardware failures (e.g., a rack losing power). Availability Zones distribute VMs across multiple distinct physical data centers within a region, providing a higher 99.99% SLA. They protect against the failure of an entire data center.

Common mistakes

Assuming Availability Sets provide 99.99% SLA, or assuming Availability Zones are supported in every single Azure region.
