質問 # 48
You have a Microsoft 365 subscription.
Your company has multiple branch offices, including a branch office named Branch1. The users in Branch1 connect to Microsoft 365 by using a corporate web proxy.
On the Network connectivity page in the Microsoft 365 admin center, Branch1 displays the following network insight:
"We're detecting WebSocket (WSS) connection failures to the domain: *.cloud.microsoft, which causes Copilot to not work correctly for your users." HTTPS access to Microsoft 365 apps from Branch1 succeeds.
You need to resolve the insight without changing connectivity for the other branch offices.
What should you configure?
正解：C
解説：
Microsoft 365 Copilot relies on secure WebSocket (WSS) connections to support real-time, bidirectional communication between client applications and Microsoft cloud services.
Option A is correct because the reported Network connectivity insight specifically identifies WebSocket connection failures for hosts within *.cloud.microsoft.
Microsoft documentation explains that this insight occurs when a network device or web proxy prevents successful WebSocket connections. Administrators should configure the affected proxy to permit WebSocket protocol connections, including the HTTP-to-WebSocket upgrade process, for the required Microsoft 365 endpoints.
Because the problem affects only Branch1, the configuration should be applied to the Branch1 web proxy policy. This resolves the connectivity issue without changing policies for other offices.
Option B is incorrect because the reported failure concerns WebSocket connectivity, not DNS resolution or regional endpoint selection.
Option C is incorrect as the best answer because TLS inspection can interfere with WebSocket connections, but the scenario does not establish that TLS inspection is the cause. Exempting endpoints from TLS inspection may be appropriate after further diagnosis, but allowing the required WebSocket protocol directly addresses Microsoft ' s reported insight.
Option D is incorrect because standard HTTPS connectivity already succeeds. Allowing HTTPS alone does not guarantee successful WebSocket protocol upgrades.
Therefore, the Branch1 proxy must allow WSS connections to the required Microsoft 365 hosts.

質問 # 49
You have a Microsoft 365 subscription that contains a Microsoft 365 group named Marketing. The subscription does NOT have a default organization theme configured.
You need to configure organization themes to meet the following requirements:
* All users must be able to see the company logo in the Microsoft 365 top navigation bar.
* Only the users in Marketing must be able to see a custom color scheme on the top navigation bar.
* The solution must use the fewest number of themes.
What should you do?
正解：B
解説：
Microsoft 365 organization themes allow administrators to customize the appearance of the Microsoft 365 top navigation bar, including company logos, background colors, text colors, and accent colors.
Option D is correct because the requirements involve two different audiences: all users and Marketing group members.
First: Configure the default organization theme.
The default organization theme applies to all users in the Microsoft 365 tenant. Administrators can configure the company ' s logo through:
Microsoft 365 admin center # Settings # Org settings # Organization profile # Custom themes.
This establishes the company branding for users who are not assigned a specific group theme.
Second: Create a group theme assigned to Marketing.
Microsoft 365 supports additional group themes that can be assigned to Microsoft 365 groups.
Administrators can create a group theme, assign the Marketing group, and configure its custom navigation bar colors. The company logo should also be configured for this theme to ensure Marketing users receive the required branding.
Option A is incorrect because a group theme alone does not establish the company logo for all other users.
Option B is incorrect because Microsoft Entra company branding controls authentication experiences rather than Microsoft 365 navigation bar themes.
Option C is incorrect because SharePoint site themes do not provide the required Microsoft 365-wide group- specific navigation bar customization.
Therefore, two themes-one default organization theme and one Marketing group theme-meet all requirements with the minimum number of themes.
Microsoft Reference:
Microsoft Learn - Customize the theme for your organization .
Final answer: D. Configure the default organization theme, and then create a group theme assigned to the Marketing group.
質問 # 50
You have a Microsoft 365 E5 subscription that contains a user named User1.
You need to perform the following actions:
* Create a shared mailbox named Mbox1 in the subscription.
* Grant User1 the Send As permission for Mbox1.
Which Microsoft 365 portals can you use to perform each task? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Microsoft Exchange Online supports shared mailbox creation and delegated mailbox permission management through both the Microsoft 365 admin center and Exchange admin center (EAC).
First selection: Exchange admin center and Microsoft 365 admin center only.
Administrators can create shared mailboxes through either administrative interface.
In the Microsoft 365 admin center, navigate to Teams & groups # Shared mailboxes # Add a shared mailbox.
Alternatively, in the Exchange admin center, navigate to Recipients # Mailboxes # Add a shared mailbox.
Both interfaces support creating Mbox1 and configuring its basic mailbox properties.
Second selection: Exchange admin center and Microsoft 365 admin center only.
Both portals support granting Send As permissions.
In the Microsoft 365 admin center, select Mbox1 under Shared mailboxes and open Manage mailbox permissions.
In the Exchange admin center, select Mbox1 under Recipients, open Manage mailbox delegation, and configure Send As permissions for User1.
The Send As permission enables User1 to send messages that appear to originate directly from Mbox1 without displaying User1 as the sender.
The Microsoft Entra admin center manages identity objects, roles, groups, and authentication settings. It does not provide the Exchange mailbox creation and mailbox delegation interfaces required by this question.
Therefore, both tasks can be performed through the Exchange admin center and Microsoft 365 admin center.

質問 # 51
You have a Microsoft 365 subscription that contains the users in your company's research department. Each research department user has an attribute of Research.
You need to create a group for the research department users. The solution must meet the following requirements:
* Provide a Microsoft SharePoint site for the group.
* Provide a shared email address.
* Minimize administrative effort.
What should you configure? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Answer Area
Correct Selection
Group type
Microsoft 365
Membership type
Dynamic User
Microsoft 365 groups provide integrated collaboration resources, including a shared email address, an Exchange Online group mailbox, a shared calendar, and a connected SharePoint team site.
First selection: Microsoft 365.
A Microsoft 365 group satisfies both collaboration requirements without requiring administrators to create separate resources.
Distribution lists and mail-enabled security groups provide email capabilities but do not automatically provision a connected SharePoint team site. Ordinary security groups also lack the required shared email functionality.
Second selection: Dynamic User.
Microsoft Entra ID supports dynamic membership based on user attributes. This allows the research department group to include eligible users automatically without manual membership updates.
Assuming the referenced attribute is the Department property, administrators can use the following rule:
(user.department -eq " Research " )
When a user ' s department changes to Research, the membership engine automatically adds that user. When the value changes to another department, the user is removed.
An Assigned membership type would require administrators or group owners to maintain membership manually. Dynamic Device is inappropriate because Microsoft 365 groups contain users, not devices.
Licensing consideration: Dynamic membership requires Microsoft Entra ID P1 licensing for affected users.
The question does not explicitly identify the licence entitlement, which should be checked before implementation.
Therefore, Microsoft 365 with Dynamic User membership meets the collaboration and administrative- efficiency requirements.
質問 # 52
You have a Microsoft 365 E5 subscription that uses Microsoft Exchange. The subscription contains a mail- enabled security group named Group1 and a user named User1.
User1 has a mailbox named Mailbox1 that is 42 GB in size.
User1 is transferred to a new role and will no longer use Mailbox1.
You need to modify Mailbox1 to meet the following requirements:
Preserve access to historical email.
Enable the users in Group1 to open Mailbox1.
Enable the Group1 users to send email messages that appear to be sent from Mailbox1.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
正解：C、D
解説：
Microsoft Exchange Online supports converting an existing user mailbox to a shared mailbox while retaining its historical email content. This is appropriate when the original user no longer needs direct access but other employees must continue using the mailbox.
Option C is correct because converting Mailbox1 into a shared mailbox preserves the existing email messages and enables delegated access for other users.
The mailbox contains 42 GB of data, which is below the standard 50 GB unlicensed shared mailbox limit.
Therefore, an additional mailbox license is not required solely because of its current size, provided no separately licensed features are necessary.
Option B is correct because Full Access permission allows Group1 members to open the mailbox and manage existing items. Send As permission enables them to send messages that appear to originate directly from Mailbox1.
Option E is incorrect because Send on Behalf permission displays the individual delegate ' s identity, whereas the requirement specifies that messages must appear to come from Mailbox1.
Option D is incorrect because Litigation Hold is designed for preservation and compliance purposes, not for providing collaborative mailbox access.
Option A is unnecessary for a standard shared mailbox of this size.
Therefore, converting the mailbox and granting Full Access and Send As permissions satisfies all three requirements.
