Question 75

Your network contains an Active Directory Domain Services (AD DS) domain named Domain1. You have a Microsoft Entra tenant. Domain1 syncs with the tenant by using Microsoft Entra Connect. You need to monitor Domain1 for privilege escalation attacks. What should you use?

A. Microsoft Entra ID Protection
B. Microsoft Defender for Servers
C. Microsoft Defender for Identity
D. Privileged Identity Management (PIM)
Show Answer
Correct Answer: C
Explanation:
Microsoft Defender for Identity is designed to monitor on-premises Active Directory Domain Services for identity-based threats, including privilege escalation, lateral movement, and compromised identities. Microsoft Entra ID Protection focuses on cloud identities in Microsoft Entra ID, Defender for Servers protects server workloads, and Privileged Identity Management manages privileged role access rather than detecting AD DS privilege escalation attacks.

Question 76

Note: This section contains one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem. You must determine whether the solution meets the stated goals. More than one solution in the set might solve the problem. It is also possible that none of the solutions in the set solve the problem. After you answer a question in this section, you will NOT be able to return. As a result, these questions do not appear on the Review Screen. You have a Microsoft 365 subscription that uses Microsoft Defender XDR. The subscription contains 500 devices that are enrolled in Microsoft Intune. The subscription contains 500 users that connect to external software as a service (SaaS) apps by using the devices. You need to implement a solution that meets the following requirements: • Allows user access to SaaS apps that Microsoft has identified as low risk • Blocks user access to Saas apps that Microsoft has identified as high risk Solution: From the Microsoft Defender portal, you set Web content filtering to On and create a web content filtering policy. Does this meet the goal?

A. Yes
B. No
Show Answer
Correct Answer: B
Explanation:
Web content filtering in Microsoft Defender for Endpoint filters websites by web content categories and custom indicators, not SaaS applications based on Microsoft Cloud App Catalog risk scores. To allow low-risk SaaS apps and block high-risk SaaS apps, you would use Microsoft Defender for Cloud Apps policies (such as access policies or Conditional Access App Control) that leverage app risk classifications.

Question 77

HOTSPOT - You have an Azure subscription that contains App Service apps in four Azure regions. Users connect to the apps from the internet. You plan to block requests to the apps if the requests contain security threats specified in the Core Rule Set (CRS) of the Open Web Application Security Project (OWASP). You need to design a solution to block the requests. The solution must meet the following requirements: • Maintain access to the apps in the event of a region outage. • Minimize the number of resources required. What should you include in the design? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: Resource type to provision: Azure Front Door Option to enable: Azure Web Application Firewall (WAF)
Explanation:
Azure Front Door is a global service that provides cross-region failover and minimizes resources. Enabling WAF with the OWASP Core Rule Set blocks malicious requests based on CRS rules.

Question 78

You have an Azure subscription and an Azure DevOps organization. You need to recommend a solution for connecting Azure DevOps pipelines to the resources in the subscription by using Azure Resource Manager (ARM) service connections. The solution must align with Microsoft Cloud Adoption Framework for Azure best practices, including the principle of least privilege. What should you include in the recommendation?

A. service principals and secrets
B. workload identity federation and service principals
C. workload identity federation and user-assigned managed identities
D. workload identity federation and system-assigned managed identities
Show Answer
Correct Answer: B
Explanation:
For Azure DevOps Azure Resource Manager service connections, Microsoft recommends workload identity federation with an automatically created app registration/service principal. This eliminates client secrets, supports least privilege through scoped RBAC assignments, and aligns with Cloud Adoption Framework guidance. User-assigned managed identity with workload identity federation is an alternative primarily when you cannot create an app registration.

Question 79

HOTSPOT - Your company uses Microsoft Defender for Cloud and Microsoft Sentinel. The company is designing an application that will have the architecture shown in the following exhibit. You are designing a logging and auditing solution for the proposed architecture. The solution must meet the following requirements: • Integrate Azure Web Application Firewall (WAF) logs with Microsoft Sentinel. • Use Defender for Cloud to review alerts from the virtual machines. What should you include in the solution? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Correct Answer: For WAF: Data connectors For the virtual machines: Defender for Servers
Explanation:
Microsoft Sentinel integrates Azure WAF logs through built-in data connectors. Microsoft Defender for Cloud surfaces VM security alerts via the Defender for Servers plan.

Question 80

HOTSPOT - You have an Azure subscription that contains an Azure Kubernetes Service (AKS) cluster named AKS1. AKS1 hosts a Windows node pool named Pool1 and a Linux node pool named Pool2. You are designing a pool update strategy for AKS1. You need to recommend how often to replace the operating system images deployed to the nodes. The solution must meet the following requirements: • Minimize how long it takes to apply operating system updates once the updates are released. • Minimize administrative effort. What should you recommend for each pool? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Illustration for SC-100 question 80
Show Answer
Correct Answer: Pool1: Monthly Pool2: Weekly
Explanation:
AKS Linux node images are released weekly, while Windows node images are typically released monthly. Updating at those cadences minimizes the delay in applying OS updates while avoiding unnecessary administrative effort.

Question 81

HOTSPOT - You have 1,000 on-premises servers that run Linux. You have an Azure subscription that contains a Microsoft Sentinel workspace named WS1 and 1,000 virtual machines that run Linux. All the on-premises Linux servers are onboarded to Azure Arc. You plan to collect Common Event Format (CEF) logs by using the Azure Monitor Agent connector in Microsoft Sentinel. You need to design a solution for collecting specific events from the logs. The solution must meet the following requirements: • Minimize the number of Microsoft Entra ID identities required. • Minimize the number of events delivered to WS1. • Ensure that all the required events are ingested. • Minimize administrative effort. What should you include in the solution? To answer, select the options in the answer area. NOTE: Each correct answer is worth one point.

Illustration for SC-100 question 81
Show Answer
Correct Answer: Create Data Collection Rules (DCRs). System-assigned managed identities for all the on-premises servers and Azure virtual machines.
Explanation:
Use DCRs with the Azure Monitor Agent to filter CEF/Syslog events before ingestion, reducing data sent while ensuring required events are collected. System-assigned managed identities minimize Microsoft Entra identities because each machine uses its own built-in identity without creating or managing shared user-assigned identities.

Question 82

You have a Microsoft Entra tenant named contoso.com. You have a partner company that has a multi-tenant application named App1. App1 is registered to a Microsoft Entra tenant named fabrikam.com. You need to ensure that the users in contoso.com can authenticate to App1. What should you recommend creating in contoso.com?

A. a service principal
B. a system-assigned managed identity
C. an application object
D. a user-assigned managed identity
Show Answer
Correct Answer: A
Explanation:
For a multi-tenant application, each consuming Microsoft Entra tenant requires a service principal (enterprise application) that represents the application in that tenant. When users or an administrator consent to the app, a service principal is created in the consuming tenant, enabling authentication. An application object exists only in the home tenant, and managed identities are for Azure resources, not user access to third-party multi-tenant apps.

Question 83

You have a Microsoft 365 tenant. Your company uses a third-party software as a service (SaaS) app named App1. App1 supports authenticating users by using Microsoft Entra credentials. You need to recommend a solution to enable users to authenticate to App1 by using their Microsoft Entra credentials. What should you include in the recommendation?

A. a relying party trust in Active Directory Federation Services (AD FS)
B. a Microsoft Entra enterprise application
C. Microsoft Entra Application Proxy
D. Microsoft Entra External ID
Show Answer
Correct Answer: B
Explanation:
To enable a third-party SaaS application to authenticate users with Microsoft Entra credentials, you integrate the application as a Microsoft Entra enterprise application. Enterprise applications provide SSO using supported federation protocols (such as SAML or OpenID Connect), centralized access management, and Conditional Access. AD FS relying party trusts are for AD FS deployments, Application Proxy publishes on-premises web apps rather than integrating SaaS apps, and External ID is for external identities, not workforce access to SaaS apps.

Question 84

HOTSPOT - You have an Azure subscription. You have a Microsoft 365 subscription. You need to assess regulatory compliance of the subscriptions. The solution must meet the following requirements: • Identify whether data stored in Azure and Microsoft 365 complies with General Data Protection Regulation (GDPR) regulations. • Identify whether Azure resources comply with National Institute of Standards and Technology (NIST) standards. • Provide recommendations on controls to improve compliance. What should you use? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Illustration for SC-100 question 84
Show Answer
Correct Answer: For NIST: Microsoft Defender for Cloud For GDPR: Microsoft Purview Compliance Manager
Explanation:
Microsoft Defender for Cloud assesses Azure resources against regulatory compliance standards such as NIST and provides recommendations. Microsoft Purview Compliance Manager assesses Microsoft 365 and Azure against regulations like GDPR and recommends compliance controls.
