Q1SC-100
Data security

Network access control

Show answer
Correct answer: Access key stored in Azure Key Vault / Azure Private Link with network service tags

When the Runbook copies data to Azure Data Lake Storage Gen2, the access keys and secrets used for the connection should not be embedded in code, but stored and protected in Azure Key Vault.
For data security, store access keys in Azure Key Vault to reduce the risk of leaking sensitive information.
For network access control, it is important to configure communication to the Automation account and related resources so that it is not exposed to the public internet.
Azure Automation can be connected privately from a VNet by using Azure Private Link, and service tags simplify rule management.
For network access control, use Azure Private Link and network service tags.
The Automation Contributor role grants management permissions and the Web Application Firewall mainly protects web apps, so neither is suitable for this purpose.

Correct answer: A. Azure Active Directory (Azure AD) B2C

The correct answer is A.
In the current Microsoft Entra framework, Azure AD B2C is positioned as the customer-facing identity capability of Microsoft Entra External ID.
It can authenticate external users with social identity providers such as Google, Facebook, and Microsoft accounts, and can be managed separately from the customer’s employee tenant.
In addition, the sign-up, sign-in, and password reset screens can be freely customized to match the app’s branding.
B2B is intended for sharing internal resources with partners and guests, so B2C is appropriate as an independent identity foundation for a consumer-facing mobile app.

Correct answer: D. Application control policy in Microsoft Defender for Endpoint

The correct answer is D.
Application control in Microsoft Defender for Endpoint uses Windows Defender Application Control (now App Control for Business).
You can implement an allow-list style control that permits only trusted applications to run.
Unapproved apps do not match the allow rules, so they are blocked from running until an administrator approves them.
Option A is session control when using cloud apps, Option B is monitoring of OAuth apps, and Option C is mainly data protection for mobile apps, so none of them are suitable for the requirement to control executable apps on Windows Server virtual machines by using an allow-list approach.
Note that Azure AD has been renamed to Microsoft Entra ID, and Endpoint Manager to Microsoft Intune.

Q4SC-100
For the on-premises datacenter

For Sub1

Show answer
Correct answer: Microsoft Azure Recovery Services (MARS) agent / Recovery Services vault

Because Server1 is an on-premises Windows Server and not an Azure virtual machine, you install the Microsoft Azure Recovery Services (MARS) agent directly on the server and transfer files, folders, and system state to Azure Backup.
You specify a Recovery Services vault as the destination for the backup data, and the MARS agent registers the server by using the vault credentials.
The Azure VM extension is for virtual machines in Azure and cannot be applied to on-premises servers.
Because the firewall blocks the internet, note that you must allow the URLs required by Azure Backup or configure a private endpoint to ensure communication.

Q5SC-100
For customers

For partners

Show answer
Correct answer: Azure AD B2C authentication / Azure AD B2B authentication using access package assignment

The correct answers are Azure AD B2C authentication for customers and Azure AD B2B authentication using access package assignment for partners.
Azure AD B2C is now a capability related to customer identity management in Microsoft Entra External ID, and it is suitable for sign-in to customer-facing apps that use social identity providers such as Facebook.
For partner companies, use B2B collaboration and assign access to resources such as SharePoint Online through access packages in entitlement management.
Both handle external identities while minimizing additional infrastructure, so they meet the requirements.
Note that Azure AD has been renamed to Microsoft Entra ID.

Q6SC-100
Show answer
Correct answer: A. Microsoft Defender for Servers

The correct answer is A.
Microsoft Defender for Servers is the server protection plan of Microsoft Defender for Cloud, and provides vulnerability assessment for Azure VMs, multicloud, and Azure Arc-enabled servers.
Under the premise of this question, the key point is that the built-in vulnerability assessment of Defender for Servers can use the Qualys engine.
Defender TI is for threat intelligence, Defender for Endpoint is for endpoint detection and response, and Defender EASM primarily manages the attack surface of externally exposed assets.
Note that integrated vulnerability scanning has now moved to Microsoft Defender Vulnerability Management, so in the latest environments you should also verify this change.

Q7SC-100
Show answer
Correct answer: B. No

The correct answer is B.
To increase the Secure management ports score, you need a configuration that does not permanently expose management ports such as RDP and SSH to the internet.
Typically, you restrict access to management ports with Just-in-Time VM access or Adaptive Network Hardening.
The VMAccess extension is a feature used mainly to recover access to a virtual machine, manage users, and reset passwords or SSH configuration, and does not continuously control the exposure of management ports.
Therefore, simply enabling the VMAccess extension does not meet the requirement to improve Secure management ports.

Q8SC-100
Show answer
Correct answer: D. An Azure managed identity

The correct answer is D.
For the credentials that an Azure DevOps service connection uses to deploy to an Azure subscription, a design that avoids long-lived passwords and user credentials is recommended.
An Azure managed identity lets you authenticate without storing secrets, because Azure automatically handles credential management and rotation.
A user account whose password is stored in Key Vault or a PIM-enabled user relies on human credentials, and a gMSA is mainly for on-premises Windows services.
In DevSecOps, using a non-interactive identity with least privilege is important.
Note that Azure AD has been renamed to Microsoft Entra ID.

Q9SC-100
Show answer
Correct answer: B. No

The correct answer is B.
The Secure management ports control evaluates whether management ports such as RDP and SSH are not exposed to the internet or are properly restricted.
To increase the score, you need a configuration that restricts access to management ports with Just-in-Time VM access or Adaptive Network Hardening.
Onboarding to Microsoft Defender for Endpoint strengthens endpoint detection, response, and vulnerability management, but does not directly control the exposure state of management ports.
Therefore, simply onboarding to Defender for Endpoint does not meet the requirement to improve Secure management ports.

Q10SC-100
To connect Azure data sources to Microsoft Information Protection

To triage security alerts related to resources containing PII data

Show answer
Correct answer: Azure Purview / Microsoft Defender for Cloud

The correct answers are Azure Purview and Microsoft Defender for Cloud.
Azure Purview is now offered as Microsoft Purview, and it can scan data sources such as Azure SQL Database and Azure Storage to detect and classify sensitive information such as PII.
Microsoft Information Protection is now also part of the Microsoft Purview Information Protection framework.
To prioritize, investigate, and triage the risks and alerts of Azure resources that contain detected sensitive data, use the security alerts and recommendations of Microsoft Defender for Cloud.
