AZ-900 Practice Test 42 — 15 Questions

Question 1

A company runs a workload that requires predictable performance and dedicated physical servers. They also need to ensure no other tenant uses the same hardware. Which cloud deployment model meets these requirements?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Private. A private cloud deployment model is correct because it provides dedicated physical servers and ensures that no other tenant shares the same hardware. In a private cloud, the infrastructure is provisioned for exclusive use by a single organization, offering predictable performance and complete isolation from other tenants. This model can be hosted on-premises or by a third-party provider, but the key requirement of dedicated hardware is met.

Answer

Public

Answer

Hybrid

Answer

Community

Question 2

Which cloud model is MOST appropriate for an organization that needs complete control over their infrastructure and cannot share resources with other organizations due to regulatory requirements?

Accepted Answer

Private cloud. A private cloud is dedicated to a single organization, providing complete control over infrastructure and ensuring no resource sharing with other tenants. This model meets regulatory requirements that mandate data isolation and compliance, as the organization can configure security policies, network segmentation, and access controls without multi-tenant risks.

Answer

Public cloud

Question 4

Which Azure feature allows you to define and enforce naming conventions for Azure resources?

Accepted Answer

Azure Policy with naming conditions. Azure Policy includes built-in or custom policy definitions that can enforce naming conventions on resources. When you assign a policy with naming conditions (e.g., requiring a specific prefix or suffix), Azure Policy evaluates all resource creation or update requests and denies or audits those that do not comply. This ensures consistent naming across your subscription without manual intervention.

Answer

Azure Blueprints

Question 5

Which Azure governance feature allows you to create a repeatable, deployable package of Azure resources, role assignments, and policies for new subscriptions?

Accepted Answer

Azure Blueprints. Azure Blueprints is the correct answer because it is specifically designed to orchestrate the deployment of a repeatable, deployable package that includes Azure Resource Manager templates, role assignments, and policies. Unlike a single ARM template, Blueprints enables you to define a set of standard Azure resources and governance artifacts that can be applied consistently to new subscriptions, ensuring compliance and organizational standards from the start.

Question 7

Which Azure service provides real-time performance monitoring and alerting for live web applications, including request rates and failure rates?

Accepted Answer

Azure Application Insights. Azure Application Insights is a feature of Azure Monitor specifically designed for Application Performance Management (APM) of live web applications. It automatically detects performance anomalies, includes powerful analytics tools to diagnose issues, and provides real-time metrics such as request rates, response times, and failure rates directly from the application code.

Answer

Azure Monitor Metrics

Answer

Azure Log Analytics

Answer

Azure Network Watcher

Question 8

Which statement accurately describes the relationship between availability and SLA percentage?

Accepted Answer

Higher SLA percentages mean less allowed downtime and typically require more redundancy. B is correct because SLA (Service Level Agreement) percentage directly correlates to the maximum allowed downtime. A higher SLA percentage, such as 99.99% versus 99%, permits less downtime per year (approximately 52.56 minutes vs. 3.65 days). To achieve higher SLAs, Azure requires implementing redundancy across availability zones or regions, as a single instance typically cannot meet the uptime guarantee.

Answer

A 99.9% SLA allows for more downtime per year than a 99% SLA

Answer

SLA percentage has no practical impact on allowed downtime

Answer

All Azure services provide the same SLA regardless of configuration

Question 9

Which of the following correctly describes Azure's approach to pricing for data transfer?

Accepted Answer

Inbound data to Azure is free; outbound data transfer incurs charges. Azure charges for outbound data transfer (egress) from Azure data centers to the internet or other regions, while inbound data transfer (ingress) into Azure is free. This pricing model encourages customers to move data into Azure without upfront cost, but charges apply when data leaves Azure's network, reflecting the bandwidth costs incurred by Microsoft.

Answer

All data transfer (inbound and outbound) is charged at the same rate

Answer

Data transfer is entirely free within Azure regardless of direction or region

Answer

Data transfer is charged based on the speed of the transfer, not the amount

Question 10

A company wants to ensure that all Azure resources are created within a specific set of approved regions. They want to automatically block any resource creation that is not in an approved region. Which Azure Policy effect should they use?

Accepted Answer

Deny. The Deny effect is correct because it actively blocks any resource creation or update that does not comply with the policy rule. In this scenario, the policy would evaluate the location property of the resource against the approved list, and if the region is not approved, the Deny effect prevents the deployment entirely, returning a 403 Forbidden error. This ensures that only resources in approved regions are created, meeting the company's requirement to automatically block non-compliant deployments.

Answer

Append

Answer

Audit

Answer

DeployIfNotExists

Question 13

Which Azure service provides a private, isolated section of the Azure cloud where you can launch Azure resources in a virtual network you define?

Accepted Answer

Azure Virtual Network (VNet). Azure Virtual Network (VNet) is the correct answer because it provides a logically isolated section of the Azure cloud dedicated to your subscription. Within a VNet, you can define your own private IP address space (using RFC 1918 addresses), subnets, and routing policies, and then launch Azure resources such as virtual machines, App Service Environments, and Azure Kubernetes Service clusters into that private network. This isolation is achieved through network segmentation and is the fundamental building block for private connectivity in Azure.

Answer

Azure Virtual WAN

Answer

Azure ExpressRoute

Answer

Azure Network Security Group

Question 14

An IT administrator needs to manage Azure resources via command line across both Windows and Linux systems. Which tools support this?

Accepted Answer

Azure CLI and Azure PowerShell (both cross-platform). Both Azure CLI and Azure PowerShell are cross-platform tools that run on Windows, Linux, and macOS. The Azure CLI uses Python-based commands, while Azure PowerShell uses PowerShell cmdlets with the Az module; both authenticate via Azure AD and interact with the Azure Resource Manager REST API. This allows the IT administrator to manage Azure resources from the command line on any operating system.

Answer

Azure CLI only (Linux) and PowerShell (Windows)

Answer

Question 15

A company wants to set monthly spending limits for each department and receive alert emails when spending reaches 80% of the budget. Which Azure tool should they use?

Accepted Answer

Azure Budgets. Azure Budgets is the correct tool because it allows you to set specific spending limits (budgets) at the subscription, resource group, or management group scope and configure alert rules that trigger when costs reach a defined threshold, such as 80% of the budget. This directly meets the requirement for monthly departmental spending limits and proactive email alerts.
