Designing and Deploying Microsoft Exchange Server 2016 — Question 105

You have an Exchange Server 2016 organization.
You have a user named User1 who must send encrypted email messages to a user named User2 in another organization.
User1 and User2 have certificates issued from a trusted third-party certification authority (CA).
You need to ensure that User1 can send the encrypted email messages to User2.
What should you do first?

Answer options

Correct answer: A

Explanation

The correct answer is A because User2 must first send a digitally signed email to User1 to establish a trust relationship and allow User1 to obtain User2's public key. The other options are incorrect as they involve unnecessary steps that do not directly facilitate the encrypted email exchange.
