Designing and Deploying Microsoft Exchange Server 2016 — Question 3

You have an Exchange Server organization. The organization contains servers that have Exchange Server 2010 and Exchange Server 2016 installed.
You establish a hybrid deployment between Exchange Server and Microsoft Office 365.
Some users have on-premises mailboxes and personal archives in Exchange Online.
You discover that you are unable to use In-Place eDiscovery to search user mailboxes and Exchange Online Archiving archives concurrently.
You need to recommend a solution to ensure that In-Place eDiscovery can search the mailboxes and the personal archives concurrently.
What should you include in the recommendation?

Answer options

Correct answer: A

Explanation

The correct answer is A, OAuth authentication, as it enables secure communication between on-premises Exchange and Exchange Online, allowing In-Place eDiscovery to search across both environments. Options B, C, and D do not provide the necessary integration for concurrent searching of mailboxes and archives, making them ineffective in this scenario.
