Accepted Answer

93 days. By default, OneDrive for Business retains deleted files in the recycle bin for 93 days. This includes both the first-stage recycle bin (30 days) and the second-stage recycle bin (an additional 63 days), totaling 93 days before permanent deletion. This default retention applies when no specific retention policy or legal hold is configured.

Answer

30 days

Answer

60 days

Answer

183 days

Question 2

An organization uses Microsoft Teams for collaboration. The security team wants to ensure that external guests cannot download files shared in Teams channels. Compliance requirements also demand that all communication in Teams be encrypted at rest and in transit. Which built-in Teams capabilities address these requirements?

Accepted Answer

Teams information barriers and default encryption. Teams information barriers can be configured to restrict external guest actions, such as preventing file downloads, while default encryption (Microsoft 365 uses BitLocker for disk-level encryption and TLS 1.2+ for data in transit) ensures all communication is encrypted at rest and in transit. These are built-in capabilities that directly address both the guest download restriction and encryption compliance requirements without additional licensing or complex configuration.

Question 3

A marketing department uses Microsoft 365 Copilot to generate content. The compliance officer is concerned about data leakage when users interact with Copilot. Which Microsoft Purview feature should the admin implement to prevent sensitive data from being used in Copilot prompts?

Accepted Answer

Microsoft Purview Data Loss Prevention (DLP) for Copilot. Microsoft Purview Data Loss Prevention (DLP) for Copilot is the correct feature because it specifically inspects and blocks sensitive data (e.g., credit card numbers, PII) from being included in Copilot prompts or generated content. DLP policies can be applied to Copilot interactions to prevent data leakage by evaluating the content in real time against sensitive information types and enforcing actions like blocking or warning the user.

Question 5

A multinational corporation uses Microsoft 365 E5 and wants to implement a retention policy that automatically deletes emails in users' mailboxes after 7 years, except for emails from the legal department which must be retained indefinitely. Which approach should the admin use?

Accepted Answer

Create a default retention policy for 7 years and use auto-labeling for legal department emails. It uses a retention policy with a 7-year deletion period for all content, then overrides that for legal department emails via auto-labeling with a 'retain indefinitely' label. This ensures that only legal emails are preserved forever while all other emails are automatically purged after 7 years, meeting the compliance requirement without manual intervention.

Question 9

Refer to the exhibit. An admin configures these two Conditional Access policies in Microsoft Entra ID. A user signs in from a new location with a device that is not compliant and is assigned a high risk level by identity protection. What will happen to the user's sign-in?

Accepted Answer

The user is blocked from signing in.. The first Conditional Access policy blocks all access for users assigned a high risk level. Since the user is assigned a high risk level by Identity Protection, this policy is triggered first, and because Conditional Access policies are evaluated in order and the first applicable policy that results in a block will prevent further evaluation, the user is blocked from signing in. The second policy requiring MFA for non-compliant devices is never evaluated because the block policy takes precedence.

Answer

The user is granted access because the second policy requires MFA.

Answer

The user is prompted for MFA due to the second policy.

Answer

The user is allowed access but with session restrictions.

Question 10

Contoso Ltd. is a medium-sized company with 2,000 users. They use Microsoft 365 E5 and have recently deployed Microsoft Teams for collaboration. The IT department has received complaints that external partners (guests) can see internal team names and member lists in the Teams directory. The compliance team requires that external guests must only see teams they are directly added to, and they must not be able to search for other teams or see internal team members who are not members of the same team. Additionally, the HR team wants to use a custom app in Teams that allows employees to submit leave requests, and this app must be available to all employees without requiring them to install anything manually. The IT admin needs to configure Teams settings to meet these requirements. Which two actions should the admin take? (Choose two. Each correct answer is part of the solution.)

Accepted Answer

Disable 'Show all teams' in the Teams admin center to prevent guests from seeing teams they are not members of.. Disabling 'Show all teams' in the Teams admin center (under Teams settings) prevents guests from seeing teams they are not members of in the Teams directory. This directly addresses the compliance requirement that external guests must only see teams they are directly added to and cannot search for other teams or see internal team members outside their own team.

Answer

Block all external access in Teams admin center to prevent guests from joining.

Answer

Configure external sharing settings in SharePoint admin center to limit guest access.

Answer

Enable external access in Teams admin center to allow guests to communicate with internal users.

Question 11

WideWorldImporters is a retail company with 500 employees. They use Microsoft 365 Business Premium. The company has a shared mailbox for customer inquiries that several employees monitor. Recently, they noticed that some emails from the shared mailbox are being deleted before being read. The IT admin investigates and finds that a PowerShell script runs daily to clean up the shared mailbox by deleting emails older than 30 days. However, some emails are being deleted before 30 days. The admin needs to ensure that no emails are deleted from the shared mailbox before they are read by at least one person. The admin also wants to retain all emails for a minimum of 30 days for compliance purposes, even if they are read. Additionally, the admin wants to prevent users from accidentally deleting emails from the shared mailbox. Which three configurations should the admin implement? (Choose three. Each correct answer is part of the solution.)

Accepted Answer

Disable the PowerShell script that deletes emails older than 30 days.. The PowerShell script is the root cause of premature deletions. Disabling it stops the automated cleanup that deletes emails before they are read, allowing the admin to implement controlled retention policies instead.

Answer

Enable the shared mailbox for archiving to move old emails to archive.

Answer

Apply a messaging records management (MRM) policy that deletes emails after 30 days.

Question 12

B is correct because Microsoft 365 Network Connectivity Center is specifically designed to analyze network performance metrics like jitter, packet loss, and latency in real time. It provides detailed insights into connection quality between a user's device and Microsoft 365 services, enabling you to pinpoint the root cause of audio drops in Teams meetings.

Question 13

Your organization is migrating from on-premises Exchange to Exchange Online. You need to ensure that users can access their mailboxes using Outlook for Windows without re-entering credentials each time. Which Microsoft 365 service should you configure to enable single sign-on (SSO) and modern authentication?

Question 15

Your organization uses Microsoft 365 E5 licenses and wants to implement a data loss prevention (DLP) policy that blocks sharing of credit card numbers in email. Which Microsoft 365 admin center should you use to create and manage this DLP policy?

Accepted Answer

Microsoft Purview compliance portal. The Microsoft Purview compliance portal is the correct admin center for creating and managing Data Loss Prevention (DLP) policies because it provides the unified compliance management interface for data protection, including DLP for Exchange Online email.
