AZ-305 · Question 36 · Domain 3.2: Design for high availability

You are deploying a cluster of 6 Azure Virtual Machines for a critical application.

You need to ensure the highest possible availability within a single Azure region. The architecture must protect against datacenter-level failures (e.g., power, cooling, or network outages affecting an entire building).

Which THREE statements regarding Availability Zones are correct? (Select THREE)

Answer options:

A.

They provide a 99.99% SLA for VM uptime.

B.

They protect against entire datacenter failures.

C.

They require deploying VMs across different physical locations within the region.

D.

They provide a 99.95% SLA for VM uptime.

E.

They protect against regional disasters (e.g., a hurricane destroying the entire region).

F.

They group VMs within the same server rack to minimize network latency.

How to approach this question

Understand the difference between Availability Sets (rack-level, 99.95%) and Availability Zones (datacenter-level, 99.99%).

Full Answer

They provide a 99.99% SLA for VM uptime, They protect against entire datacenter failures, and They require deploying VMs across different physical locations within the region.
Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. Deploying VMs across multiple zones protects against datacenter-level failures and provides an industry-leading 99.99% SLA. They do not protect against region-wide disasters (which require multi-region architectures).

Common mistakes

Confusing the SLA of Availability Sets (99.95%) with Availability Zones (99.99%).
