  2. Review the Microsoft 365 Message center notices.
  3. Add and verify the domain through the Microsoft 365 admin center with the requested DNS record.
  4. Review and update organization settings in the Microsoft 365 admin center.

Explanation

Correct Answer

D:

Organization settings govern tenant-level service preferences and contact data. This directly addresses central organization profile administration.

Incorrect Answers

A:

Service health tracks provider incidents and advisories by workload. This helps with official current service incident visibility instead of the required central organization profile administration.

B:

Message center announcements communicate feature rollout and required admin actions. The action is relevant to planned service change notices rather than central organization profile administration.

C:

Domain verification establishes control of the organization namespace. This helps with verified custom tenant domain instead of the required central organization profile administration.

Question 21

Six reception agents must answer messages sent to one common address without shared passwords. How should the administrator address this situation?

  1. Configure a shared mailbox and delegate access to the agents.
  2. Create a distribution group for the recipients.
  3. Create a Microsoft 365 group for the project.
  4. Use a licensed user mailbox for the employee.

Explanation

Correct Answer

A:

Shared mailbox delegation supports a team-operated inbox under one address. This directly addresses jointly handled helpdesk messages.

Incorrect Answers

B:

Distribution groups expand mail addressed to a group into member delivery. That addresses mail-only announcement distribution, whereas the current case requires jointly handled helpdesk messages.

C:

Microsoft 365 groups provide linked collaborative services, including a group mailbox and site. It is used for integrated membership-backed collaboration; this scenario calls for jointly handled helpdesk messages.

D:

A user mailbox is associated with the person's account and personal work mail. That addresses personal employee messaging, whereas the current case requires jointly handled helpdesk messages.

Question 22

Users say a message was delivered late and IT needs a per-message delivery path. Which administration choice BEST meets this requirement?

  1. Configure a scoped mail flow rule in the Exchange admin center.
  2. Run message trace in the Exchange admin center.
  3. Configure the domain as an accepted domain in Exchange Online.
  4. Configure an appropriate mail-receive restriction on the mailbox.

Explanation

Correct Answer

B:

Incorrect Answers

A:

  2. Create an appropriate SharePoint site for that department.
  3. Create a document library within its SharePoint site.
  4. Add folders within the existing document library.

Explanation

Correct Answer

C:

Libraries provide file storage, versioning and metadata in the site. This directly addresses managed documents with versions.

Incorrect Answers

A:

Lists manage structured rows and business records. The action is relevant to structured nonfile tracking records rather than managed documents with versions.

B:

Sites form independent workspace boundaries with their own membership and content. This helps with a department-wide collaborative container instead of the required managed documents with versions.

D:

Folders group library items without creating a separate site or library. This helps with hierarchical filing within a library instead of the required managed documents with versions.

Question 24

Contributors need to add and modify documents but should not administer the site's permissions. Which administration choice BEST meets this requirement?

  1. Assign the SharePoint site Visitors read role.
  2. Review and set unique permissions on that item where justified.

C:
