Question 1

A company needs to design a secure DevOps pipeline using GitHub Actions and Microsoft Defender for Cloud. They want to scan infrastructure-as-code (IaC) templates for misconfigurations before deployment. What should they integrate?

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

Accepted Answer

Microsoft Defender for Cloud Infrastructure as Code scanning. Microsoft Defender for Cloud includes a native Infrastructure as Code (IaC) scanning capability that integrates directly with GitHub Actions. This feature automatically analyzes IaC templates (such as ARM, Bicep, Terraform, and CloudFormation) for security misconfigurations during the CI/CD pipeline, providing pre-deployment guardrails. By failing the pipeline on critical findings, it ensures only compliant infrastructure is deployed, aligning with the secure DevOps principle of shifting security left.

Question 8

Your organization needs to enforce multi-factor authentication (MFA) for all users accessing sensitive applications. You plan to use Microsoft Entra ID Conditional Access. Which grant control should you configure?

Accepted Answer

Require multi-factor authentication. The question specifies a requirement to enforce MFA for all users accessing sensitive applications. In Microsoft Entra ID Conditional Access, the 'Require multi-factor authentication' grant control directly enforces Azure AD MFA (e.g., via Microsoft Authenticator, OATH tokens, or SMS) as the primary authentication method. This is the simplest and most direct control to meet the stated goal of requiring MFA, without adding additional constraints like device compliance or authentication strength levels.

Answer

Require authentication strength (e.g., phishing-resistant MFA)

Answer

Require device to be marked as compliant

Answer

Use app enforced restrictions

Question 9

A company plans to implement Microsoft Purview to enforce data loss prevention (DLP) policies. They need to prevent users from sharing credit card numbers via email. What should they configure?

Accepted Answer

Create a DLP policy that detects and blocks credit card numbers in Exchange Online. Microsoft Purview Data Loss Prevention (DLP) policies can be configured to detect sensitive data types, such as credit card numbers, in Exchange Online emails. When a DLP policy is created with a rule that identifies credit card numbers and blocks the email from being sent, it directly prevents users from sharing that data via email. This is the native mechanism for enforcing DLP on email traffic in Microsoft 365.

Answer

Question 15

A company uses Microsoft Intune to manage devices. They need to ensure that only compliant devices can access corporate email. They plan to use Conditional Access in Microsoft Entra ID. Which THREE components must be configured?

Accepted Answer

Device registration in Entra ID. Device registration in Entra ID (A) is required because Conditional Access policies evaluate device compliance based on the device's identity in Entra ID. Without registration, the device lacks a unique identity that Entra ID can assess for compliance status, making it impossible to enforce access controls based on device state.

Answer

Windows Autopilot deployment profile

Answer

Configuration profile in Intune

Question 16

Question 17

A company uses Microsoft Defender for Cloud to assess the security posture of their Azure subscriptions. They want to ensure that all virtual machines have the Log Analytics agent installed and that missing system updates are remediated automatically. Which two recommendations should be enabled in a single policy initiative?

Accepted Answer

Enable the Microsoft Defender for Cloud 'System Updates' and 'Log Analytics agent' recommendations via a built-in initiative.. Microsoft Defender for Cloud includes a built-in policy initiative (the 'ASC Default' initiative) that contains both the 'System Updates' and 'Log Analytics agent' recommendations. Enabling this single initiative automatically assigns both requirements to the selected scope, ensuring that missing system updates are remediated and the Log Analytics agent is installed on all virtual machines without needing custom policies or separate assignments.

Answer

Assign two separate Azure Policy initiatives, one for each requirement.

Answer

Create a custom Azure Policy initiative that combines the two requirements.

Answer

Use Azure Blueprints to assign the policies to all subscriptions.

Question 18

Refer to the exhibit. You are reviewing a Conditional Access policy in Azure AD. The policy requires MFA and a compliant device for all users and all cloud apps. Some users report that they are able to access apps without being prompted for MFA even though their devices are compliant. What is the most likely reason?

Accepted Answer

The policy is set to 'Report-only' mode. A Conditional Access policy set to 'Report-only' mode evaluates the policy and logs results but does not enforce any controls, such as requiring MFA or a compliant device. Users can access apps without MFA prompts because the policy is not actively blocking or challenging them, even if their devices are compliant. This mode is used for testing before enabling enforcement.

Answer

The policy does not include all cloud apps

Answer

The policy excludes specific locations

Answer

The policy does not include session controls to enforce MFA re-prompt

Question 19

A company is implementing a Zero Trust security model using Microsoft 365 Defender. Which THREE of the following are key principles they should follow?

Accepted Answer

Use least privilege access by limiting user permissions with Just-In-Time and Just-Enough-Access.. Zero Trust mandates least privilege access, and Microsoft 365 Defender integrates with Azure AD Privileged Identity Management (PIM) to enforce Just-In-Time (JIT) and Just-Enough-Access (JEA) policies. This ensures users receive only the permissions necessary for a specific task, for a limited duration, reducing the risk of lateral movement and privilege escalation.

Answer

Trust all traffic originating from within the corporate network.

Answer

Provide implicit trust to known users and devices.

Question 20

Contoso, a healthcare provider, is deploying a new patient portal on Azure App Service that stores electronic health records (EHR) in Azure Cosmos DB for NoSQL. The solution must comply with HIPAA and HITRUST. You need to ensure that data is encrypted at rest and in transit, and that access is restricted based on user roles. Cosmos DB must be configured with a private endpoint to prevent public internet access. You plan to use Azure Key Vault to manage encryption keys. Additionally, the application will access Cosmos DB using a system-assigned managed identity. Which of the following is the most complete and secure design?

Accepted Answer

Enable encryption at rest using a customer-managed key in Azure Key Vault, enforce TLS 1.2, configure a private endpoint for Cosmos DB, and grant the managed identity access via Azure RBAC with a custom role that allows read/write to specific containers.. It provides the most comprehensive security for HIPAA/HITRUST compliance. Customer-managed keys in Azure Key Vault give Contoso control over encryption keys, which is required by HIPAA. TLS 1.2 ensures encryption in transit. A private endpoint for Cosmos DB prevents public internet access, offering better isolation than service endpoints or firewall rules. Finally, granting the managed identity access via Azure RBAC with a custom role allows granular, least-privilege access to specific containers, which is more secure than using built-in roles or connection strings. Option A is wrong because service-managed keys do not provide the key control required for HIPAA, and service endpoints are less secure than private endpoints. Option B is wrong because disabling encryption at rest is a security risk and contrary to compliance requirements; also, storing a read-write key in Key Vault (to be retrieved by the app) is less secure than using managed identity with RBAC. Option C is wrong because firewall rules are less secure than private endpoints, and storing read-write keys in application settings is a security risk.

Answer

Enable encryption at rest using service-managed keys, enforce TLS 1.2, configure a service endpoint for Cosmos DB, and grant the managed identity access using Cosmos DB built-in roles (e.g., Cosmos DB Built-in Data Contributor).

Answer

Disable encryption at rest to improve performance, enforce TLS 1.2, configure a private endpoint, and use the managed identity with a read-write key in Azure Key Vault.

Answer

Enable encryption at rest using service-managed keys, enforce TLS 1.2, configure a firewall to allow only the App Service outbound IP, and use read-write keys in application settings.
