SC-900 Practice Test 16 — 15 Questions

Question 1

A company uses Microsoft Entra ID. They want to require all users accessing the external vendor portal to accept a terms of use document before they are granted access. The acceptance must be revoked after 30 days, requiring the user to accept again. Which Conditional Access component should the administrator configure?

Accepted Answer

Access controls (Grant). The administrator needs to enforce a terms of use acceptance that expires after 30 days. In Conditional Access, the 'Access controls (Grant)' section includes the 'Require terms of use' option, which can be configured to require re-acceptance after a specified duration (e.g., 30 days). This directly meets the requirement by blocking access until the user accepts the current version of the terms of use document.

Session controls

Question 2

A company uses Microsoft Entra ID. They want to require users to perform multifactor authentication (MFA) every 90 days on trusted devices, but force MFA for every sign-in on untrusted devices. Which Conditional Access session control must they configure to meet this requirement?

Accepted Answer

Sign-in frequency. Sign-in frequency is the Conditional Access session control that allows administrators to define the time interval after which a user must re-authenticate, even on a trusted device. By setting the sign-in frequency to 90 days for trusted devices and requiring re-authentication for every sign-in on untrusted devices (by setting the frequency to 0 or 1), the requirement is met. This control directly manages the re-prompt interval for MFA, independent of the session token lifetime.

Answer

Application enforced restrictions

Answer

Use app enforced restrictions

Answer

Persistent browser session

Question 3

A company wants to automatically apply a 'Confidential' sensitivity label to any document that contains a credit card number, and also encrypt the document as part of the label. Which two components must be configured to achieve this? (Choose two.)

Accepted Answer

A sensitivity label with encryption settings. Option A is correct because a sensitivity label must include encryption settings to automatically encrypt documents when the label is applied. The encryption is configured within the label's protection settings, which defines how content is protected (e.g., with a predefined template or user-defined permissions). Without encryption configured in the label, the automatic application would only assign the label without encrypting the document.

Answer

A DLP policy that detects sensitive info

Answer

A data classification dashboard

Question 4

A company wants to ensure that data is not altered during transmission between a client and a server. They use TLS encryption. Which security goal does this primarily address?

Accepted Answer

Integrity. TLS (Transport Layer Security) uses message authentication codes (MACs) and cryptographic hashing to ensure that data is not tampered with during transit. While TLS also provides confidentiality through encryption, the specific goal of preventing alteration during transmission is integrity. Therefore, option B is correct because integrity guarantees that the data received is exactly what was sent, unchanged by any intermediary.

Answer

Confidentiality

Answer

Availability

Answer

Non-repudiation

Question 5

A company wants to allow employees to securely access internal applications from their personal devices. The security policy requires that access is only granted if the device is compliant with company security policies (e.g., encryption enabled, password required, up-to-date operating system). Which Microsoft Entra ID capability should they use?

Accepted Answer

Conditional Access. Conditional Access in Microsoft Entra ID is the correct capability because it allows administrators to define policies that enforce device compliance before granting access to applications. By integrating with Microsoft Intune, Conditional Access can require that devices meet specific security policies—such as encryption, password requirements, and OS updates—before allowing access. This directly addresses the requirement to grant access only from compliant personal devices.

Answer

Identity Protection

Answer

Privileged Identity Management

Answer

Microsoft Entra Verified ID

Question 6

A company wants to block all sign-ins using legacy authentication protocols because these protocols do not support multi-factor authentication (MFA). Which component of a Microsoft Entra ID Conditional Access policy should be configured to achieve this?

Accepted Answer

Conditions (Client apps). To block legacy authentication protocols, you configure the 'Client apps' condition in a Conditional Access policy. This setting allows you to target specific authentication clients, such as Exchange ActiveSync, POP3, IMAP, and SMTP, which do not support MFA. By selecting 'Exchange ActiveSync clients' and 'Other clients' under the Client apps condition, you can enforce a block on all sign-ins using these legacy protocols.

The solution should integrate with Microsoft Sentinel and Microsoft 365 Defender for cross-domain investigations. Which Microsoft security solution should they deploy?

Accepted Answer

Microsoft Defender for Identity. Microsoft Defender for Identity (MDI) is specifically designed to protect on-premises Active Directory by monitoring for advanced attacks like Kerberos Golden Ticket, pass-the-hash, and brute-force attempts. It integrates natively with Microsoft Sentinel and Microsoft 365 Defender to enable cross-domain investigations, correlating identity signals with endpoint and cloud data.

Question 8

A company wants to improve its security posture across Microsoft 365. The security team needs a central dashboard that provides a score based on current security configurations, gives recommendations for improving the score, and allows tracking of improvement actions over time. Which Microsoft security solution should they use?

Accepted Answer

Microsoft Secure Score. Microsoft Secure Score is the correct solution because it provides a central dashboard that calculates a numerical score based on the tenant's current security configurations across Microsoft 365 services. It offers prioritized improvement actions, tracks progress over time, and allows security teams to monitor and manage their security posture in a single view.

Question 9

A financial company processes stock trades. To ensure that a trader cannot later deny having submitted a specific trade order, the system captures a digital signature from the trader for each order. Which security goal is being addressed by this practice?

Accepted Answer

Non-repudiation. Non-repudiation ensures that a party cannot deny having performed a specific action. By capturing a digital signature from the trader for each trade order, the system creates cryptographic proof that the trader indeed submitted that order. This prevents the trader from later claiming they did not authorize the trade, directly addressing the non-repudiation goal.

Answer

Confidentiality

Answer

Integrity

Answer

Availability

Question 10

A financial institution uses digital signatures to ensure that a transaction record has not been altered after it was processed. Which security principle is primarily addressed?

Accepted Answer

B. Integrity. Digital signatures use asymmetric cryptography (e.g., RSA or ECDSA) to create a hash of the transaction record, which is then encrypted with the sender's private key. Any alteration to the record after signing would cause the hash verification to fail, directly ensuring data integrity. This is why option B is correct.

Answer

A. Confidentiality

Answer

C. Availability

Answer

D. Non-repudiation

Question 11

An organization is redesigning its security architecture based on the Zero Trust model. Which principle requires that every access request must be fully authenticated, authorized, and encrypted before granting access, regardless of the network location?

Accepted Answer

Verify explicitly. The Zero Trust model is built on three core principles: verify explicitly, least privilege, and assume breach. The principle that mandates every access request—regardless of whether it originates from inside or outside the corporate network—must be fully authenticated, authorized, and encrypted before granting access is 'verify explicitly'. This means using strong authentication methods (e.g., multifactor authentication), continuous validation of authorization (e.g., Conditional Access policies), and enforcing encryption (e.g., TLS 1.3) for every request, not just those from untrusted locations.

Answer

Assume breach

Answer

Least privilege

Answer

Trust but verify

Question 12

A financial services company is required by the Payment Card Industry Data Security Standard (PCI-DSS) to retain all documents containing credit card numbers for at least seven years. The compliance team has created a custom sensitive information type (SIT) to detect credit card numbers in Microsoft 365. They want to automatically apply a retention label (e.g., "7-Year Retention") to any document in SharePoint or OneDrive that matches this SIT. Which Microsoft Purview solution should they configure to apply the label automatically based on content?

Accepted Answer

Data Lifecycle Management. Data Lifecycle Management (DLM) in Microsoft Purview is the solution specifically designed for automatically applying retention labels based on conditions like sensitive information types (SITs). By creating a retention label policy with auto-labeling rules that reference the custom SIT for credit card numbers, DLM can automatically assign the '7-Year Retention' label to documents in SharePoint and OneDrive that contain PCI-DSS data, ensuring compliance with retention requirements.

Question 15

A financial services organization must comply with a regulation that requires all communications related to trades (including emails and Teams messages) to be retained for a period of 7 years. During retention, no user may edit or delete these records. After the 7 years, the records must be disposed of with an irreversible deletion that is verified by a compliance officer. Which Microsoft Purview solution should the organization use to enforce both retention and regulatory disposition?

Accepted Answer

Microsoft Purview Records Management (regulatory retention label). Microsoft Purview Records Management with a regulatory retention label is the correct solution because it enforces immutable retention (no user edits or deletions) and mandates a disposition review by a compliance officer before irreversible deletion. Regulatory labels lock the retention policy at the highest level, preventing any user or administrator from shortening the retention period or bypassing the disposition workflow, which aligns with the 7-year retention and verified disposal requirement.
