Implementing a Hybrid and Secure Messaging Platform (legacy) — Question 10

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

Correct answer: B

Explanation

The correct answer is B because creating 10 GALs allows each department to have its own address list, ensuring users can only see members of their respective department. The other options do not provide the necessary separation of address lists for each department, which is essential for achieving the desired visibility in the GAL.
