Question 1

South Ridge School District uses Microsoft 365 Education A5. They have 10,000 students and 1,000 staff. The district wants to ensure that student data is protected and that only authorized staff can access student records. They also need to comply with FERPA (Family Educational Rights and Privacy Act). The IT team has created security groups for teachers, administrators, and support staff. They want to restrict access to a specific SharePoint site containing student records to only the teachers group. Additionally, they want to prevent teachers from sharing the site with external users. What should you configure?

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

Accepted Answer

In the SharePoint site settings, set the site permissions to 'Only members of the Teachers group can access' and set external sharing to 'Only people in your organization'.. Sharing controls in SharePoint site settings can be used to limit access to specific groups and disable external sharing. Option B (private channel) is for Teams, not SharePoint. Option C (sensitivity label) can restrict access but is not site-specific. Option D (site collection admin) does not restrict sharing.

Answer

Apply a sensitivity label to the site that restricts access to the teachers group.

Answer

Add the teachers group as site collection administrators.

Answer

Create a private channel in Microsoft Teams for teachers only.

Question 2

Fabrikam Inc. is a technology company that uses Microsoft 365 E5. They have implemented Microsoft Defender XDR to monitor for threats. The security team wants to receive alerts when a user is compromised, such as when a user's credentials are used from an unusual location. They also want to automatically block the user from signing in until the risk is mitigated. You need to configure a solution that automatically detects and responds to such identity risks. What should you configure?

Accepted Answer

Configure Identity Protection in Microsoft Entra ID to detect risky sign-ins and enable the 'User risk policy' to automatically block high-risk users.. Identity Protection in Microsoft Entra ID detects risky sign-ins and users, and its User risk policy can automatically block high-risk users. Option A (Microsoft Defender for Cloud Apps) monitors app-level activities but does not directly handle identity risk-based blocking. Option C (Microsoft Sentinel) is a SIEM that can detect threats but requires manual or custom automation for automatic user blocking. Option D (Conditional Access) can enforce MFA but does not automatically block users based on risk without Identity Protection integration.

Answer

Enable Microsoft Defender for Cloud Apps to monitor user activities.

Answer

Deploy Microsoft Sentinel and create analytics rules to detect and respond to identity threats.

Answer

Create a Conditional Access policy that requires MFA for all sign-ins.

Question 3

A financial services company must prevent users from accidentally sharing sensitive customer data externally. They want to block sharing of any document containing a credit card number via email or SharePoint. What combination of Microsoft 365 compliance solutions should they use?

Accepted Answer

Data Loss Prevention (DLP) policies. Data Loss Prevention (DLP) policies in Microsoft Purview are specifically designed to detect and block the sharing of sensitive information, such as credit card numbers, across email (Exchange Online) and SharePoint. By scanning content for predefined sensitive info types (e.g., credit card numbers using regex patterns from the DLP engine), DLP can automatically block or warn users before external sharing occurs, meeting the company's requirement.

Question 4

A healthcare organization stores patient records in SharePoint Online. They need to ensure that the data is encrypted at rest and in transit. Which statement is true regarding Microsoft 365 encryption?

Accepted Answer

Microsoft provides default encryption for data at rest and in transit.. Microsoft 365 provides default encryption for data at rest and in transit across all workloads, including SharePoint Online, Exchange Online, and OneDrive for Business. For data at rest, Microsoft uses BitLocker Drive Encryption and service-side encryption with per-file keys, while data in transit is secured using TLS 1.2+ and IPSec. This means the healthcare organization's patient records in SharePoint Online are automatically encrypted without any manual configuration.

Answer

Customers must enable encryption at rest manually for each workload.

Answer

Encryption only applies to Exchange Online, not SharePoint or OneDrive.

Answer

Encryption is optional and can be turned off if a customer chooses.

A company uses Microsoft Purview to monitor for potential data security incidents. They want to automatically detect and remediate activities like downloading large amounts of data to a personal device. Which solution should they configure?

Accepted Answer

Insider Risk Management. Insider Risk Management is the correct solution because it is specifically designed to detect and remediate risky user activities that could lead to data security incidents, such as downloading large amounts of data to a personal device. It uses machine learning and behavioral analytics to identify anomalous patterns and can trigger automated remediation actions like blocking the activity or notifying the user.

Question 8

A company uses Microsoft 365 (a SaaS offering). A security incident occurs where an employee's account is compromised because the employee reused their corporate password on a personal website. According to the shared responsibility model, who is primarily responsible for this security failure?

Accepted Answer

The customer (the company using Microsoft 365). In the Microsoft 365 shared responsibility model, the customer is responsible for securing user identities, including password hygiene and multi-factor authentication (MFA). Since the employee reused their corporate password on a personal website, this is a customer-side identity management failure, not a platform vulnerability. Microsoft secures the SaaS infrastructure, but customer-managed credentials fall under the customer's responsibility.

Answer

Microsoft, because they provide the SaaS platform

Answer

Both Microsoft and the customer share equal responsibility

Answer

It depends on the contract terms with Microsoft

Question 9

A security team needs to ensure that all Microsoft 365 administrative actions—such as creating user accounts or resetting passwords—are logged and searchable for at least 90 days. They also need to create custom alert rules for suspicious admin activity. Which Microsoft Purview solution should they use?

Accepted Answer

Microsoft Purview Audit (Standard). Microsoft Purview Audit (Standard) logs and retains all administrative actions (e.g., creating users, resetting passwords) for 90 days by default, meeting the retention requirement. It also supports creating custom alert rules for suspicious admin activity via the Microsoft 365 Defender portal, which queries the audit log. This makes it the correct solution for both logging and alerting on admin actions.

A legal firm needs to send a confidential document to a client via email. The firm requires that the client cannot forward or print the email and that the email expires after seven days. Which Microsoft Purview solution should they use?

Accepted Answer

Microsoft Purview Message Encryption. Microsoft Purview Message Encryption (A) is the correct solution because it allows the legal firm to apply usage restrictions such as preventing forwarding and printing, and to set an expiration period of seven days on the email. This is achieved through Azure Rights Management (Azure RMS) templates that enforce these controls directly on the encrypted message, ensuring the client cannot bypass the restrictions.

Question 14

A compliance officer wants to proactively prevent users from sending emails that contain sensitive personal data (e.g., credit card numbers) to external recipients. When a user attempts to send such an email, they should see a policy tip explaining the restriction and be blocked from sending. Which Microsoft Purview feature should be configured?

Accepted Answer

Microsoft Purview Data Loss Prevention (DLP) policy. Microsoft Purview Data Loss Prevention (DLP) policy is the correct feature because it is specifically designed to detect sensitive data (e.g., credit card numbers) in transit and enforce actions such as showing a policy tip and blocking the email.
