AZ-900 - Microsoft Azure Fundamentals Azure Core Architectural Components Questions and Answers

Question 1

A company is planning to deploy a critical application on Azure Virtual Machines. They need to ensure the application remains available even if a single datacenter in an Azure region fails. Which Azure concept should they use to achieve this level of resilience?

Accepted Answer

Availability Zones

Answer

Availability Zones are physically separate locations within an Azure region, each with its own power, cooling, and networking. Deploying virtual machines across multiple Availability Zones ensures that if one zone experiences an outage (equivalent to a datacenter failure), the VMs in the other zones remain operational, providing high availability for the application.

Question 2

Which of the following is the primary function of an Azure Resource Group?

Accepted Answer

To function as a logical container for grouping and managing related Azure resources that share a common lifecycle.

Answer

An Azure Resource Group is a fundamental organizational unit that acts as a logical container to hold related resources for an Azure solution. This grouping allows for collective management, including deployment, updating, and deletion of all resources as a single unit, which is ideal for resources that share the same lifecycle.

Question 3

A large enterprise has numerous Azure subscriptions for different departments (e.g., HR, Finance, IT). The central IT team needs to apply a consistent set of security policies and access controls across all these subscriptions efficiently. What is the most appropriate Azure feature to use for this purpose?

Accepted Answer

Management Groups

Answer

Management Groups are designed for this exact scenario. They sit above subscriptions in the Azure hierarchy and allow organizations to apply governance controls, such as policies and role-based access control (RBAC), across multiple subscriptions at scale. This avoids the repetitive and error-prone task of configuring each subscription individually.

Question 4

An organization is deploying resources to an Azure region and must comply with data sovereignty laws that require customer data to remain within a specific geopolitical boundary. Which Azure architectural component defines these boundaries and ensures data residency?

Accepted Answer

Geography

Answer

An Azure Geography is a defined area of the world, often aligned with geopolitical boundaries, that contains one or more Azure regions. Geographies are designed to meet data residency, sovereignty, and compliance requirements, ensuring that data stored in a region within that geography stays there.

Question 5

Which of the following is a key capability of the Azure Resource Manager (ARM)?

Accepted Answer

Offering a consistent management layer that processes all requests for Azure resources, whether from the portal, CLI, or SDKs.

Answer

Azure Resource Manager (ARM) is the central deployment and management service for Azure. It provides a consistent management layer, processing all requests through a single API, regardless of the tool used (Azure Portal, PowerShell, CLI, etc.). This ensures consistent application of policies, locks, and access controls.
