Question 2

A company needs to grant a group of users the ability to restart and start/stop virtual machines, but not to create or delete them. They want to assign this permission at the resource group level. What should they do?

Accepted Answer

Create a custom role with the required actions. Azure's built-in roles do not provide a granular permission set that allows restarting and starting/stopping VMs while explicitly denying creation and deletion. A custom role must be created with specific actions such as 'Microsoft.Compute/virtualMachines/start/action', 'Microsoft.Compute/virtualMachines/restart/action', and 'Microsoft.Compute/virtualMachines/deallocate/action', and exclude actions like 'Microsoft.Compute/virtualMachines/write' and 'Microsoft.Compute/virtualMachines/delete'. This custom role can then be assigned at the resource group scope to grant the precise permissions required.

Question 4

A company wants to move their on-premises infrastructure to the cloud to avoid the large upfront cost of purchasing new servers every three years. In the cloud, they will pay only for the server capacity they use, with no long-term commitment. This shift from upfront investment to variable expense is an example of which cloud benefit?

Accepted Answer

Consumption-based pricing. Consumption-based pricing is a cloud model where customers pay only for the resources they actually use (e.g., compute hours, storage GBs) with no upfront costs or long-term commitments. This directly matches the scenario of avoiding large upfront server purchases and paying only for capacity used, shifting from a capital expenditure (CapEx) to an operational expenditure (OpEx) model.

Answer

Economies of scale

Answer

Capacity planning

Answer

Reserved capacity

Question 5

Which Azure service enables automated build and release pipelines triggered by code changes in a Git repository?

Accepted Answer

Azure Pipelines. Azure Pipelines is the correct service because it is specifically designed for continuous integration and continuous delivery (CI/CD), enabling automated build and test workflows that trigger on code changes in a Git repository. It supports multiple Git providers (e.g., GitHub, Azure Repos, Bitbucket) and can deploy to any target, making it the native DevOps solution for automating pipelines from source control commits.

Question 6

A company is designing a solution that requires guaranteed message delivery and exactly-once processing for financial transactions. Which Azure messaging service should they use?

Accepted Answer

Azure Service Bus. Azure Service Bus is the correct choice because it supports guaranteed message delivery through its 'Peek-Lock' and 'Scheduled Delivery' features, and it provides exactly-once processing via duplicate detection (based on the MessageId property) and transaction support (atomic operations across multiple entities). This makes it ideal for financial transactions where message loss or duplication is unacceptable.

Question 7

A solutions architect is designing a storage solution for a large media company. The company needs to store video files that are accessed infrequently but must be retained for several years for compliance. Which two Azure storage options meet these requirements? (Select two.)

Accepted Answer

Blob Storage - Cool tier. Blob Storage Cool tier is correct because it is designed for data that is accessed infrequently but needs to be stored for at least 30 days, offering lower storage costs than the Hot tier while maintaining low-latency access. Blob Storage Archive tier is correct because it is the lowest-cost storage option for data that is rarely accessed and has a flexible retrieval time (hours), making it ideal for long-term compliance retention of video files.

Answer

Blob Storage - Hot tier

Answer

Azure Files - Premium tier

Question 8

A company uses Azure Policy to enforce encryption on storage accounts. They discover some existing storage accounts are non-compliant. They want to automatically enable encryption on these accounts without manual intervention. Which combination of policy effects should they use?

Accepted Answer

Audit and DeployIfNotExists. The correct combination is Audit and DeployIfNotExists. Audit logs non-compliant storage accounts without blocking them, while DeployIfNotExists automatically enables encryption on those accounts by deploying a remediation task. This ensures existing non-compliant resources are brought into compliance without manual intervention.

Answer

Deny and Audit

Answer

Append and Modify

Answer

Audit and Disabled

Question 9

Which Azure service provides a way to automatically extract and load data from external SaaS applications like Salesforce and ServiceNow into Azure data stores?

Accepted Answer

Azure Data Factory. Azure Data Factory (ADF) is the correct answer because it is a cloud-based ETL (Extract, Transform, Load) and data integration service specifically designed to ingest data from a wide variety of sources—including SaaS applications like Salesforce and ServiceNow—and load it into Azure data stores such as Azure SQL Database, Azure Data Lake Storage, or Azure Synapse Analytics. ADF provides built-in connectors for these SaaS platforms, enabling automated, scheduled, or event-triggered data movement without requiring custom code.

Question 10

A startup wants to use cloud services to launch their product quickly without investing in hardware. Which cloud benefit does this BEST describe?

Accepted Answer

Agility and speed to market. The startup's need to launch quickly without upfront hardware investment directly maps to the cloud benefit of agility and speed to market. Azure's pay-as-you-go model and instant provisioning of virtual machines (e.g., Azure VMs) or platform services (e.g., Azure App Service) eliminate procurement delays, allowing deployment in minutes rather than weeks. This is the core value proposition of cloud computing for rapid product iteration.

Answer

Fault tolerance

Answer

Disaster recovery

Answer

Geographic distribution

Question 11

A company pays a monthly subscription fee for cloud services based on the resources they consume, such as the number of virtual machines or amount of storage used. There are no upfront costs or fixed long-term commitments. This pricing model is known as:

Accepted Answer

Pay-as-you-go. Pay-as-you-go (also called consumption-based pricing) is the correct model because it charges the customer only for the actual resources consumed (e.g., VM hours, storage GBs) with no upfront payment or termination penalties. This aligns directly with the scenario of a monthly subscription fee based on resource usage without long-term commitments.

Answer

Reserved instances

Answer

Spot pricing

Answer

Hybrid benefit

Question 12

A company uses Azure Policy to require encryption on storage accounts. They want to automatically deploy an encryption extension to any new storage account that does not have it enabled, without manual intervention. Which policy effect should they use?

Accepted Answer

DeployIfNotExists. DeployIfNotExists is the correct effect because it evaluates resources after creation and automatically deploys a required configuration (like an encryption extension) if it is missing, without requiring manual intervention. This effect is specifically designed for scenarios where you need to remediate non-compliant resources by deploying a template or extension, ensuring encryption is enabled on all storage accounts.

Answer

Modify

Answer

Append

Answer

AuditIfNotExists

Question 13

Which Azure service provides a way to deploy and manage Azure services at the edge, close to IoT devices and end users?

Accepted Answer

Azure IoT Edge. Azure IoT Edge is correct because it extends cloud intelligence to edge devices, allowing you to deploy and manage Azure services (like Azure Functions, Stream Analytics, and custom modules) directly on IoT devices or gateways. This enables local data processing and decision-making close to IoT sensors and end users, reducing latency and bandwidth usage.

Answer

Azure IoT Hub

Answer

Azure Stack Edge

Answer

Question 14

A company wants to organize their Azure subscriptions into a hierarchy for policy and cost management. They have multiple departments, each with multiple subscriptions. What should they create first to establish this structure?

Accepted Answer

Management groups. Management groups are the correct first step because they provide a hierarchical structure above subscriptions, enabling you to organize multiple subscriptions into logical groupings for policy and cost management. By creating management groups first, you can then apply Azure Policy and cost controls at the management group level, which automatically cascades to all child subscriptions and resource groups. This aligns with the Azure governance hierarchy: management groups → subscriptions → resource groups → resources.

Answer

Resource groups

Answer

Policies

Answer

Subscriptions

Question 15

Which Azure concept represents the hierarchical organization of management groups, subscriptions, resource groups, and resources?

Accepted Answer

Azure Resource Hierarchy. The Azure Resource Hierarchy is the correct answer because it defines the four-level structure—management groups, subscriptions, resource groups, and resources—that Azure uses to organize and manage access, policy, and compliance. This hierarchy allows you to apply Azure Policy and role-based access control (RBAC) at any level, with inheritance flowing downward. It is the foundational model for governance in Azure, distinct from geographic or deployment concepts.

Answer

Azure Geographic hierarchy

Answer

Azure Deployment slots hierarchy

Answer

Azure Tenant and Region structure
