Microsoft 365 Messaging — Question 13

Your company has a Microsoft Exchange Server 2019 organization.
The company has 10,000 mailboxes. Each department at the company has 1,000 mailboxes.
You need to ensure that when users query the global address list (GAL), they can view only the list of the users in their department.
What should you create?

Answer options

• A. 10 GALs, 10 offline address books (OABs), 10 address lists, 10 room lists, and 10 email address policies
• B. one GAL, 10 offline address books (OABs), 10 address lists, 10 room lists, and one address book policy (ABP)
• C. one GAL, 10 offline address books (OABs), 10 address lists, 10 address book policies (ABPs), and one email address policy
• D. 10 GALs, 10 offline address books (OABs), 10 address lists, 10 room lists, and 10 address book policies (ABPs)

Correct answer: D

Explanation

The correct answer is D, as creating multiple GALs ensures that users only see the members from their specific department. Options A and B do not provide the necessary separation of mailboxes by department, and option C incorrectly suggests a single GAL, which does not meet the requirement for departmental visibility.
