SC-900 Practice Test 8 — 10 Questions

Question 1

A user reports that they cannot access a critical application, receiving an error that their session has expired. The sign-in logs show the user was prompted for multifactor authentication (MFA) multiple times during the same session. What should an administrator review to reduce these interruptions?

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

Accepted Answer

Microsoft Entra Conditional Access session controls. Session controls in Conditional Access policies can be configured to reduce repeated MFA prompts within the same session, such as by adjusting the sign-in frequency or persistent browser session settings. Option A is wrong because tenant-wide MFA settings enforce MFA globally but do not control session-specific behavior. Option C is wrong because Identity Protection focuses on risk-based policies, not directly on session lifetime. Option D is wrong because Privileged Identity Management manages role activation and assignment, not session controls.

Answer

Microsoft Entra tenant-wide MFA settings

Answer

Microsoft Entra Identity Protection policies

Answer

Microsoft Entra Privileged Identity Management settings

Question 2

Match each security control type to its example.

Accepted Answer

Preventive: Firewall rules blocking unauthorized traffic. Security control types categorize how controls operate: preventive controls block incidents, detective controls identify them, and corrective controls fix issues. Common examples include firewall rules (preventive), IDS (detective), and backup/restore (corrective).

Answer

Preventive: Intrusion detection system monitoring network traffic

Answer

Detective: Backup and restore procedures

Answer

Corrective: Firewall rules blocking unauthorized traffic

Question 3

Match each Azure security service to its purpose.

Accepted Answer

Microsoft Defender for Cloud: A unified infrastructure security management system that strengthens security posture and provides advanced threat protection.. Common confusions involve mixing up the purposes of security management (Defender for Cloud), SIEM/SOAR (Sentinel), and secret management (Key Vault).

Answer

Microsoft Defender for Cloud: A cloud-native SIEM and SOAR solution.

Answer

Azure Sentinel: A tool for securely storing and managing secrets, keys, and certificates.

Answer

Azure Key Vault: A unified infrastructure security management system that strengthens security posture.

Question 4

A multinational organization uses Microsoft 365 and must demonstrate compliance with both GDPR and ISO 27001. The compliance team needs a centralized tool to assess their current compliance posture against these frameworks, receive prioritized improvement actions, and track the implementation of those actions over time. Which Microsoft Purview solution should they use?

Accepted Answer

Compliance Manager. Compliance Manager is the correct solution because it provides a centralized dashboard that assesses an organization's compliance posture against frameworks like GDPR and ISO 27001. It offers prioritized improvement actions based on built-in assessments and tracks the implementation of those actions over time, directly meeting the requirements for a unified compliance management tool.

Answer

Data Lifecycle Management

Answer

Audit

Answer

eDiscovery

Question 5

You are reviewing a Microsoft Sentinel KQL query. What is the primary purpose of this query?

```kql
SigninLogs
| where TimeGenerated > ago(7d)
| where AppDisplayName == "Microsoft Teams"
| summarize TotalAttempts = count(), FailedAttempts = countif(ResultType != 0) by UserPrincipalName
| where TotalAttempts > 10 and FailedAttempts > 5
| project UserPrincipalName, TotalAttempts, FailedAttempts
```

Accepted Answer

Identify users with high logon attempts to Teams and high failed sign-ins, possibly indicating a brute-force attack. The query filters Microsoft Teams sign-ins from the last 7 days, aggregates total and failed sign-in attempts per user, and returns users with more than 10 total attempts and more than 5 failed attempts. This pattern of high volume and repeated failure is indicative of a brute-force attack, making option B correct. The query does not filter for global administrator role or conditional access policies.

Answer

Identify all users who have attempted to log on to Microsoft Teams more than 10 times in the last 7 days and who are global administrators

Answer

Identify users with high failed sign-ins and check if they have conditional access policies applied

Answer

Identify users with high successful logon attempts to Teams and correlate with failed sign-ins to detect account compromise

Question 6

Refer to the exhibit. A Microsoft Purview administrator imported this JSON policy for automatic sensitivity labeling. After deployment, users report that emails containing German social security numbers are not being automatically labeled. What is the most likely cause?

Accepted Answer

Auto-labeling for emails requires 'applyWithOverride' behavior, not 'apply'.. Microsoft Purview auto-labeling for emails requires the 'applyWithOverride' action to allow users to override the label, whereas 'apply' is used for static labeling in other scenarios like SharePoint. The JSON policy uses 'apply' without override, which prevents automatic labeling on emails, as email auto-labeling policies specifically need the 'applyWithOverride' behavior to function correctly.

Answer

The sensitive info type 'EU_Deutschland_SocialSecurityNumber' is not defined in the tenant.

Answer

The encryption setting prevents auto-labeling on emails.

Answer

The label is not published to users.

Question 7

A user reports that they cannot access the company's HR application, which requires Microsoft Entra ID authentication. The user can access other apps that also use Entra ID. What is the most likely cause?

Accepted Answer

A conditional access policy is blocking access to that specific app.. The user can access other Microsoft Entra ID-integrated apps, which rules out account-level issues like a disabled account or expired password. A conditional access policy can target specific applications, so it is the most likely cause of the block on just the HR app.

Answer

The user's account is disabled.

Answer

The tenant is blocked for all sign-ins.

Answer

The user's password expired.

Question 8

A user downloads a software update from a company's internal website. The update file is hashed, and the hash value is published on a separate secure page. After downloading, the user computes the hash of the downloaded file and compares it to the published hash. The two values match. Which security concept is primarily demonstrated by this comparison?

Accepted Answer

Integrity. Hashing is a one-way cryptographic function that produces a fixed-size digest from input data. By comparing the computed hash of the downloaded file to the published hash, the user verifies that the file has not been altered during transit or storage. This directly demonstrates the security concept of integrity, which ensures data has not been tampered with or corrupted.

Answer

Confidentiality

Answer

Availability

Answer

Authentication

Question 9

Which TWO Microsoft Purview solutions help organizations respond to data subject requests under GDPR?

Accepted Answer

eDiscovery. eDiscovery (A) is correct because it enables organizations to search for and export personal data across Microsoft 365 workloads (Exchange, SharePoint, OneDrive, Teams) to fulfill data subject access and export requests under GDPR Article 15. Data Lifecycle Management (C) is correct because it allows organizations to retain personal data for the minimum necessary period and permanently delete it when no longer needed, supporting the right to erasure under GDPR Article 17.

Answer

Information barriers

Answer

Data Loss Prevention (DLP)

Answer

Communication compliance

Question 10

Your organization uses Microsoft Entra ID to manage user identities. A new employee named John joins the company and needs access to Microsoft 365 apps. You want to ensure John's identity is verified using a phone call. Which authentication method should you configure?

Accepted Answer

Phone call (voice call). The question explicitly requires verification using a phone call. The Phone call (voice call) authentication method in Microsoft Entra ID delivers an automated voice call to the user's registered phone number, prompting them to press a key to confirm their identity. This directly matches the requirement, making D the correct choice.

Answer

Time-based one-time password (TOTP)

Answer

Email one-time passcode

Answer

Text message (SMS)

Answer

FIDO2 security key
