AZ-900 Practice Test 24 — 15 Questions

Question 1

Which Azure cost optimization practice involves analyzing resource usage and removing or resizing underutilized resources?

Accepted Answer

Right-sizing underutilized resources. Right-sizing underutilized resources is a core Azure cost optimization practice that involves analyzing resource usage metrics (e.g., CPU, memory, disk I/O) and then either resizing to a smaller SKU or deallocating idle resources. This directly reduces compute, storage, and licensing costs by aligning capacity with actual demand, as opposed to paying for over-provisioned capacity.

Question 2

Which Azure storage service uses a flat namespace for storing objects and can host static websites?

Accepted Answer

Azure Blob Storage (static website hosting). Azure Blob Storage provides a flat namespace (container/blob hierarchy) and supports static website hosting by enabling a static website endpoint on a storage account. This allows users to serve HTML, CSS, and JavaScript files directly from a blob container without needing a web server.

Question 3

What is the purpose of Azure Cost Management budgets?

Accepted Answer

To set spending thresholds and receive alerts when approaching those limits. Azure Cost Management budgets allow you to set spending thresholds (e.g., monthly, quarterly) and configure alerts that notify you via email or action groups when costs reach a certain percentage of the budget (e.g., 50%, 90%, 100%). This enables proactive cost governance without automatically stopping resources, which is not a built-in budget action.

Answer

To automatically stop resources when spending exceeds a defined limit

Answer

To transfer unused budget from one resource to another

Answer

To reserve compute capacity for future use

Question 4

A company has a legacy on-premises application that processes sensitive financial data. Due to regulatory requirements, certain data cannot leave the company's on-premises data center. However, the company wants to take advantage of the cloud's scalability for the application's compute-intensive batch processing jobs. The batch jobs need to access the sensitive data but must process it without the data ever being stored in the cloud. The batch jobs will be orchestrated from the cloud. Which cloud deployment model best describes this architecture?

Accepted Answer

Hybrid cloud. This architecture is a hybrid cloud because it combines on-premises infrastructure (where sensitive data resides and must remain) with public cloud resources (for compute-intensive batch processing). The batch jobs are orchestrated from the cloud but access the sensitive data on-premises without storing it in the cloud, which is a classic hybrid deployment pattern. Hybrid cloud enables workload portability and orchestration across private and public environments while meeting data residency and regulatory requirements.

Answer

Public cloud

Answer

Private cloud

Answer

Multi-cloud

Question 5

A company wants to connect an on-premises network to Azure with a dedicated private connection that bypasses the internet. Which service should they use?

Accepted Answer

Azure ExpressRoute. Azure ExpressRoute is the correct service because it provides a dedicated, private connection from an on-premises network directly into Azure, bypassing the public internet entirely. This ensures lower latency, higher reliability, and greater security compared to internet-based connections, and it supports higher bandwidth options.

Question 6

Which Azure feature creates an audit trail showing who performed what actions on Azure resources and when?

Accepted Answer

Azure Activity Log. The Azure Activity Log is a platform log in Azure that provides insight into subscription-level events, recording all control-plane operations (e.g., creating a VM, deleting a resource group) with details on who performed the action (via Azure AD principal), what the action was, and when it occurred. This makes it the correct feature for creating an audit trail of resource management actions.

Answer

Azure Network Watcher packet captures

Question 7

Which Azure feature ensures that users accessing sensitive applications must be on compliant corporate devices?

Accepted Answer

Azure AD Conditional Access with device compliance. Azure AD Conditional Access with device compliance enforces policies that require users to access sensitive applications only from devices that meet compliance standards (e.g., managed by Intune, patched, encrypted). This integrates with Microsoft Intune to check device health before granting access, ensuring corporate data is protected.

Answer

Azure AD Identity Protection

Answer

Azure RBAC with device restrictions

Answer

Azure Firewall with IP restrictions

Question 8

Which Azure storage service is best suited for storing unstructured data such as images, videos, and log files?

Accepted Answer

Azure Blob Storage. Azure Blob Storage is designed for storing massive amounts of unstructured data, such as images, videos, and log files. It offers three types of blobs (block, append, and page) to optimize for different access patterns, making it the ideal choice for binary and text data that does not fit a relational schema.

Answer

Azure Files

Answer

Azure Queue Storage

Answer

Azure Table Storage

Question 9

A company runs a web application on two VMs in the same Availability Set. What is the guaranteed SLA for the VMs?

Accepted Answer

99.95%. Microsoft guarantees a 99.95% SLA for two or more virtual machines deployed in the same Availability Set because the set distributes VMs across separate fault domains and update domains, ensuring that at least one VM remains available during planned maintenance or hardware failures. The SLA applies only when all VMs are in the same Availability Set and all disks are managed disks, as per the Azure Compute SLA terms.

Answer

99.9%

Answer

99.99%

Answer

100%

Question 10

A company is considering moving its on-premises workloads to the cloud. They want to reduce their carbon footprint by using a cloud provider that uses renewable energy. Which cloud computing benefit is most directly related to this goal?

Accepted Answer

C) Sustainability. Sustainability directly addresses the goal of reducing carbon footprint through the use of renewable energy. Cloud providers like Microsoft Azure invest in renewable energy projects and carbon offset programs, enabling customers to lower their environmental impact by consolidating workloads in energy-efficient data centers. This benefit is explicitly tied to environmental responsibility, not operational metrics like uptime or resource scaling.

Answer

A) High availability

Answer

B) Scalability

Answer

D) Elasticity

Question 11

A company deploys a web application on Azure VMs across two different physical locations within the same Azure region. These locations are isolated from each other in terms of power, cooling, and networking. If one location fails, the application remains available from the other location. Which feature achieves this?

Accepted Answer

Availability zones. Availability zones are physically separate locations (datacenters) within an Azure region, each with independent power, cooling, and networking. By deploying VMs across two zones, the application remains available if one zone fails, achieving high availability. This matches the scenario exactly.

Answer

Availability sets

Question 14

A company uses Azure Blueprints to define a standard environment with policies, role assignments, and resource groups. They publish a new version of the blueprint that adds a new role assignment. However, existing subscriptions created from older versions do not have this new role assignment. What must they do to apply the update to existing subscriptions?

Accepted Answer

They need to update the existing blueprint assignment to use the latest published version.. Azure Blueprints assignments are not automatically updated when a new version of the blueprint is published. To apply the new role assignment to existing subscriptions, you must update the existing blueprint assignment to reference the latest published version. This triggers Azure to evaluate and apply the changes defined in the new version, including the new role assignment, to the assigned subscriptions.

Answer

Delete and recreate the subscriptions using the new blueprint.

Answer

The blueprint version update is automatically applied to all existing subscriptions.

Answer

They must manually assign the role to each subscription.

Question 15

A company uses Azure SQL Database for a web application. They need to ensure that the database can automatically scale to handle sudden spikes in traffic without downtime. Which feature should they enable?

Accepted Answer
