AZ-900 Quick Quiz — 10 Questions

Question 1

A company has a policy that all Azure Storage accounts must have diagnostic settings enabled to send logs and metrics to a specific Log Analytics workspace. The governance team wants to automatically configure these diagnostic settings when a new storage account is created, without blocking the initial creation. The solution must not require manual intervention. Which Azure Policy effect should the team use in their policy definition?

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

Accepted Answer

DeployIfNotExists. The DeployIfNotExists effect is correct because it automatically deploys a remediation task to configure diagnostic settings on storage accounts that lack them, without blocking the initial creation of the resource. This effect evaluates resources after creation and triggers a deployment to bring non-compliant resources into compliance, which aligns with the requirement for automatic configuration without manual intervention.

Question 2

A global e-commerce company has web applications deployed on Azure virtual machines in the West US and West Europe regions. The company needs a single, global HTTP-based entry point that can perform SSL offloading, route requests based on the URL path (e.g., /api to one backend pool, /images to another), and provide a web application firewall (WAF) to protect against common web attacks. Additionally, the solution must automatically direct users to the closest regional deployment to minimize latency. Which Azure service should the company use?

Accepted Answer

Azure Front Door. Azure Front Door is the correct choice because it provides a global, HTTP/HTTPS-based entry point with SSL offloading, URL path-based routing to different backend pools, and a built-in web application firewall (WAF). It also uses Anycast-based routing to automatically direct users to the closest regional deployment, minimizing latency.

Question 3

A company wants to proactively identify Azure resources that are misconfigured and could lead to security vulnerabilities, such as virtual machines with open management ports or unencrypted storage accounts. They also need to get prioritized recommendations for remediating these issues. Which Azure service should the company use?

Accepted Answer

Microsoft Defender for Cloud (formerly Azure Security Center). Microsoft Defender for Cloud (formerly Azure Security Center) is the correct service because it continuously assesses the security posture of Azure resources, identifies misconfigurations such as open management ports (e.g., RDP/SSH) or unencrypted storage accounts, and provides prioritized, actionable recommendations for remediation. It integrates with Azure Policy to enforce security standards and offers a secure score to track improvement over time.

Question 4

Which Azure service enables you to synchronize your on-premises Active Directory with Azure Active Directory?

Accepted Answer

Azure AD Connect. Microsoft Entra Connect is the correct service because it is specifically designed to synchronize on-premises Active Directory identities with Microsoft Entra ID, enabling hybrid identity scenarios. It handles password hash synchronization, pass-through authentication, and federation integration, ensuring users have a single identity for both on-premises and cloud resources.

Azure Multi-Factor Authentication

Question 5

A company has an on-premises data center with a site-to-site VPN connection to Azure. The company wants to ensure that the connection remains secure by encrypting all traffic between the on-premises network and Azure virtual network. The connection must be established over the public internet. Which Azure service should the company use to create this encrypted tunnel?

Accepted Answer

Azure VPN Gateway. Azure VPN Gateway is the correct service because it creates an encrypted site-to-site VPN tunnel over the public internet using IPsec/IKE protocols. This meets the requirement for a secure connection between the on-premises data center and Azure virtual network over the public internet.

Question 6

A company has a critical Azure Storage account that stores immutable backups. The IT administrator wants to ensure that no one can delete or modify this storage account, even administrators with Contributor or Owner roles. The company still needs to allow read access to the data within the storage account. Which Azure governance feature should the administrator implement?

Accepted Answer

Azure Resource Manager read-only lock. An Azure Resource Manager read-only lock prevents any user, including those with Contributor or Owner roles, from deleting or modifying the storage account while still allowing read access to the data. This lock operates at the management plane, blocking DELETE and PATCH operations via the Azure Resource Manager API, but does not affect data plane operations like reading blobs or files.

Azure Blueprint with role assignment

Answer

Azure role-based access control (RBAC) with Reader role

Question 7

A company is developing a new web application. The development team wants to deploy the application code without having to manage the underlying virtual machines, operating systems, or runtime environments. They only want to focus on writing code and let the cloud provider handle the infrastructure, platform, and scaling automatically. Which cloud service model does this scenario describe?

Accepted Answer

Platform as a Service (PaaS). This scenario describes Platform as a Service (PaaS) because the development team wants to deploy application code without managing the underlying virtual machines, operating systems, or runtime environments. PaaS provides a managed hosting environment where the cloud provider handles infrastructure, platform updates, and automatic scaling, allowing developers to focus solely on writing and deploying code. In contrast, IaaS would require managing VMs and OS, while SaaS delivers fully built applications, not a platform for custom code deployment.

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Answer

Function as a Service (FaaS)

Question 8

A company manages hundreds of Azure SQL databases across multiple subscriptions. The compliance team requires that every Azure SQL database has diagnostic settings enabled to send logs to a central Log Analytics workspace. The team wants a solution that automatically configures diagnostic settings for any new Azure SQL database when it is created, without requiring manual intervention or additional scripting. Which Azure governance feature should the team use?

Accepted Answer

Azure Policy with the DeployIfNotExists effect. Azure Policy with the DeployIfNotExists effect is the correct choice because it automatically evaluates new Azure SQL databases against a policy rule and, if diagnostic settings are missing, triggers a remediation task to deploy them to the specified Log Analytics workspace. This effect operates at resource creation time without manual intervention or scripting, fulfilling the compliance team's requirement for automatic, consistent configuration across all subscriptions.

Question 9

What is an Azure availability zone?

Accepted Answer

A physically separate datacenter within an Azure region with independent power and cooling. An Azure availability zone is a physically separate datacenter within an Azure region, each with its own independent power, cooling, and networking. This isolation ensures that if one zone fails, applications and data in other zones remain unaffected, providing high availability and fault tolerance for critical workloads.

Answer

A geographic region with multiple Azure datacenters

Answer

A pair of geographically distant Azure regions

Answer

A logical grouping of Azure resources for billing

Question 10

Which Azure service provides dedicated physical servers for regulatory or licensing requirements where hardware cannot be shared with other customers?

Accepted Answer

Azure Dedicated Host. Azure Dedicated Host provides physical servers dedicated to a single Azure subscription, ensuring that hardware is not shared with other customers. This meets regulatory or licensing requirements that mandate hardware isolation, such as specific compliance standards or software licensing agreements that restrict usage to dedicated hardware.
