AZ-900 Azure Core Architectural Components 2 — Questions and Answers
Question 1: What is the primary purpose of an Azure region pair?
- To provide disaster recovery with replication and prioritized recovery (Correct answer)
- To double compute capacity in one location
- To reduce networking costs between subscriptions
- To merge two billing accounts
Correct answer: To provide disaster recovery with replication and prioritized recovery
Region pairs sit within the same geography and provide resilience through data replication and prioritized region recovery during outages.
Question 2: Which Azure resource is the smallest deployable unit of compute that you create and manage?
- A resource (Correct answer)
- A management group
- A subscription
- A geography
Correct answer: A resource
A resource is a manageable item such as a VM, database, or storage account that you create in Azure.
Question 3: What logically groups multiple subscriptions for unified governance and policy?
- Management groups (Correct answer)
- Availability zones
- Resource groups
- Region pairs
Correct answer: Management groups
Management groups sit above subscriptions and let you apply governance and policy across many subscriptions at once.
Question 4: An availability zone is best described as which of the following?
- A physically separate datacenter within an Azure region (Correct answer)
- A logical container for resources
- A copy of data in another geography
- A billing boundary
Correct answer: A physically separate datacenter within an Azure region
Availability zones are physically separate datacenters within a single region, each with independent power, cooling, and networking.
Question 5: Which statement about a resource group is correct?
- A resource can only belong to one resource group at a time (Correct answer)
- A resource can belong to multiple resource groups
- Resource groups must contain only one resource
- Resource groups span multiple subscriptions
Correct answer: A resource can only belong to one resource group at a time
Each resource exists in exactly one resource group, though you can move it to another group.
Question 6: What does an Azure geography primarily ensure?
- Data residency and compliance boundaries (Correct answer)
- Lower VM pricing
- Faster CPU performance
- Automatic code deployment
Correct answer: Data residency and compliance boundaries
A geography is a discrete market that preserves data residency and compliance requirements.
Question 7: Which Azure component acts as a billing and access management boundary?
- Subscription (Correct answer)
- Resource
- Availability zone
- Region pair
Correct answer: Subscription
A subscription is a unit of management, billing, and scale that links resources to an account.
