Question 9

What is an Azure Region

Answer 9

Geographical area containing one of more datacenters, networked together on low-latency network.

You can choose the region you want your resource deployed.

Question 10

What is an Azure availability zone?

Answer 10

Physically separate datacenters within an Azure region. Set up to be an isolation boundary - if one zone goes down, the other continues to work.

Question 11

How are Azure availability zones connected?

Answer 11

Through high-speed, private fibre-optic networks

Question 12

What services are Azure availability zones primarily for?

Answer 12

• VMs
• Managed disks
• Load balancers
• SQL databases

Question 13

What are the 3 Azure service categories that support availability zones?

Answer 13

• Zonal services
• Zone-redundant services
• Non-regional services

Question 14

What happends with a Zonal Service

Answer 14

Resource is pinned to specific zone.

(for example, VMs, managed disks, IP addresses).

Question 15

What happens with zone-redundant services?

Answer 15

The platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).

Question 16

Non-regional services

Answer 16

Services are always available from Azure geographies and are resilient to zone-wide outages as well as region-wide outages.

Question 17

What are Azure Region Pairs?

Answer 17

Most Azure regions are paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away.

This approach allows for the replication of resources across a geography that helps reduce the likelihood of interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages.

Question 18

Sovereign Regions

Answer 18

Sovereign regions are instances of Azure that are isolated from the main instance of Azure. You may need to use a sovereign region for compliance or legal purposes.

Question 19

What is a resource?

Basic building block of Azure. Anything you create, provision, deploy, etc. is a resource. Virtual Machines (VMs), virtual networks, databases, cognitive services, etc. are all considered resources within Azure.
