Microsoft Certified: Security, Compliance, and Identity FundamentalsPractice Set 1: All Questions & Explanations

Full question text, answer options, and explanations for this practice set — a spoiler-free alternative is the interactive quiz above for scored, shuffled practice.

  1. 1. Your organization is planning its cloud security strategy. Which model describes how security responsibilities are divided between a cloud provider and the customer?

    • A. Zero Trust model
    • B. Shared responsibility model(correct)
    • C. Defense-in-depth model
    • D. Governance, Risk, and Compliance (GRC) model

    Explanation: The shared responsibility model defines which security tasks are handled by the cloud provider and which are handled by the customer. The division varies depending on the cloud service type (IaaS, PaaS, SaaS). The Zero Trust model is about never trusting by default, defense-in-depth layers security controls, and GRC covers governance processes.

  2. 2. An identity architect states that 'identity is the new security perimeter.' What does this mean in the context of modern security?

    • A. Physical network perimeters are no longer needed
    • B. Verifying user identity is the primary method of controlling access to resources(correct)
    • C. Passwords alone are sufficient to protect all resources
    • D. Cloud services eliminate the need for authentication

    Explanation: In modern cloud and mobile environments, users access resources from anywhere on any device. Traditional network perimeters are insufficient, so verifying user identity becomes the primary control for protecting resources. This shifts security from 'where you are on the network' to 'who you are.'

  3. 3. Your organization wants to implement a security strategy that assumes no user or device is trusted by default, even within the corporate network. Which security model should your organization adopt?

    • A. Perimeter-based security model
    • B. Defense-in-depth model
    • C. Zero Trust model(correct)
    • D. Shared responsibility model

    Explanation: The Zero Trust model operates on the principle of 'never trust, always verify.' It assumes breach and verifies each request explicitly regardless of where it originates. Defense-in-depth layers multiple security controls but does not inherently assume distrust of internal network traffic. Perimeter-based security trusts internal traffic, which Zero Trust explicitly rejects.

  4. 4. A new employee needs access to Microsoft 365 applications. Which Microsoft service provides identity and access management for cloud-based applications?

    • A. Microsoft Defender for Identity
    • B. Microsoft Entra ID(correct)
    • C. Microsoft Sentinel
    • D. Microsoft Purview

    Explanation: Microsoft Entra ID (formerly Azure Active Directory) is Microsoft's cloud-based identity and access management service. It provides authentication and authorization for Microsoft 365, Azure, and thousands of third-party SaaS applications. Microsoft Defender for Identity focuses on detecting identity-based attacks, Sentinel is a SIEM/SOAR solution, and Purview handles compliance and data governance.

  5. 5. Your organization has an on-premises Active Directory environment and a Microsoft Entra ID tenant. Users currently maintain separate credentials for on-premises and cloud resources. You need to allow users to use a single set of credentials for both environments. What should you implement?

    • A. Microsoft Entra ID Protection
    • B. Hybrid identity using Microsoft Entra Connect(correct)
    • C. Microsoft Entra Privileged Identity Management
    • D. Microsoft Entra External ID

    Explanation: Hybrid identity with Microsoft Entra Connect synchronizes on-premises Active Directory identities with Microsoft Entra ID, enabling users to use a single set of credentials for both on-premises and cloud resources. Entra ID Protection detects identity risks, Privileged Identity Management manages privileged role assignments, and External ID is for external user identities.

  6. 6. You are a security administrator. You need to require users to complete additional verification steps when signing in from unrecognized locations. Which Microsoft Entra ID feature should you configure?

    • A. Self-service password reset (SSPR)
    • B. Microsoft Entra ID Protection
    • C. Conditional Access policies(correct)
    • D. Access reviews

    Explanation: Conditional Access policies in Microsoft Entra ID allow you to enforce access controls based on conditions such as location, device compliance status, user risk, and application sensitivity. You can require multifactor authentication (MFA) when users sign in from unfamiliar locations. SSPR allows password resets, ID Protection detects risks, and access reviews periodically verify user access rights.

  7. 7. Your organization wants to strengthen authentication for privileged administrator accounts. Which two authentication methods are available in Microsoft Entra ID to provide multifactor authentication? Choose 2.

    • A. Microsoft Authenticator app push notifications(correct)
    • B. Username and password only
    • C. FIDO2 security keys(correct)
    • D. Shared group passwords
    • E. Anonymous authentication tokens

    Explanation: Microsoft Entra ID supports multiple MFA methods including the Microsoft Authenticator app (push notifications, passwordless phone sign-in) and FIDO2 security keys (hardware-based passwordless authentication). Username/password alone is single-factor, shared group passwords violate security best practices, and anonymous tokens are not a supported authentication method.

  8. 8. You are configuring governance for your Microsoft Entra ID environment. You need to ensure that users' privileged role assignments are time-limited and require approval before activation. Which feature should you configure?

    • A. Microsoft Entra ID Protection
    • B. Microsoft Entra Privileged Identity Management (PIM)(correct)
    • C. Microsoft Entra Conditional Access
    • D. Microsoft Entra Access Reviews

    Explanation: Microsoft Entra Privileged Identity Management (PIM) provides just-in-time privileged access management. It allows you to make role assignments eligible rather than permanent, require justification and approval before activation, set time limits on active assignments, and receive notifications and audit logs of privileged activity. Conditional Access enforces access policies at sign-in, ID Protection detects compromised identities, and Access Reviews periodically recertify user access.

  9. 9. Your organization needs to periodically verify that employees still require their assigned application access and group memberships. Which Microsoft Entra ID Governance feature should you use?

    • A. Entitlement management
    • B. Access reviews(correct)
    • C. Conditional Access
    • D. Identity Protection

    Explanation: Access reviews in Microsoft Entra ID Governance allow organizations to efficiently manage group memberships, access to enterprise applications, and role assignments. Reviewers can certify or remove access on a recurring schedule. Entitlement management automates access request workflows, Conditional Access enforces sign-in policies, and Identity Protection detects compromised accounts.

  10. 10. Your organization uses multiple SaaS applications. You need users to authenticate once and have access to all applications without re-entering credentials. Which capability does Microsoft Entra ID provide to meet this requirement?

    • A. Multifactor authentication (MFA)
    • B. Single sign-on (SSO)(correct)
    • C. Self-service password reset (SSPR)
    • D. Role-based access control (RBAC)

    Explanation: Single sign-on (SSO) in Microsoft Entra ID allows users to sign in once and access multiple applications without needing to re-authenticate. MFA adds a verification step during authentication, SSPR allows users to reset their own passwords, and RBAC controls what actions a user can perform within applications.

  11. 11. Your organization wants to protect its Azure virtual machines from distributed denial-of-service (DDoS) attacks. Which Azure service provides this protection?

    • A. Azure Firewall
    • B. Azure DDoS Protection(correct)
    • C. Azure Bastion
    • D. Network Security Groups (NSGs)

    Explanation: Azure DDoS Protection provides defense against DDoS attacks at layers 3 and 4 of the network stack. It automatically detects and mitigates attacks targeting your Azure resources. Azure Firewall is a managed stateful firewall, Azure Bastion provides secure RDP/SSH access to VMs, and NSGs filter inbound and outbound traffic but do not provide DDoS-specific mitigation.

  12. 12. You are a security engineer. Your organization runs web applications in Azure. You need to protect these applications from common web exploits such as SQL injection and cross-site scripting (XSS). Which Azure service should you use?

    • A. Azure DDoS Protection
    • B. Azure Key Vault
    • C. Web Application Firewall (WAF)(correct)
    • D. Network Security Groups (NSGs)

    Explanation: Web Application Firewall (WAF) provides protection against common web application vulnerabilities including SQL injection, cross-site scripting, and other OWASP Top 10 threats. WAF can be deployed with Azure Application Gateway or Azure Front Door. DDoS Protection addresses volumetric attacks, Key Vault manages secrets and keys, and NSGs filter network traffic but do not inspect HTTP application payloads.

  13. 13. Your security team needs a centralized solution to store and manage application secrets, encryption keys, and certificates for Azure workloads. Which service should you recommend?

    • A. Azure Active Directory
    • B. Microsoft Defender for Cloud
