Answer 20

Policies and permissions applied to a management group are inherited by all its subscriptions and resource groups.

Question 21

What is the Microsoft Learn Sandbox?

Answer 21

A temporary subscription provided by Microsoft Learn to create and test Azure resources during exercises.

Question 22

What is the purpose of billing profiles in Azure?

Answer 22

To create separate invoices and payment methods within the same billing account.

Question 23

Why use availability zones in your application architecture?

Answer 23

To run mission-critical applications with high availability and resilience by replicating resources across zones.

Question 24

What are the three types of Azure services related to zones?

Answer 24

Zonal services (pinned to a specific zone).
Zone-redundant services (automatically replicated across zones).
Non-regional services (resilient to zone and region outages).

Question 25

How do region pairs enhance resilience?

Answer 25

Automatic failover during outages.
Synchronized updates to minimize downtime.
Data residency within the same geography for legal compliance.

Question 26

What are examples of non-regional Azure services?

Answer 26

Azure Traffic Manager, Microsoft Entra ID, and Azure DNS.

Question 27

What is the unique aspect of Brazil South’s region pair?
