You are the Office 365 administrator for your company.
The company has established the following new requirements:
Members of the legal team must be able to conduct eDiscovery searches. Employees must be notified when they send email messages that contain confidential
information.
You need to configure the environment.
Which two actions should you perform? Each correct answer presents part of the solution.

A.
Configure journaling to a Microsoft Exchange Online mailbox for all mailboxes.

B.
Add the members of the legal team to the Discovery Management role group.

C.
Create a Data Loss Prevention policy.

D.
Place all executive mailboxes on In-Place Hold for 365 days and use In-Place eDiscovery for mailbox searches.

E.
Enable Microsoft Exchange Online Archiving for the executive mailboxes.

F.
Place all executive mailboxes on Retention Hold.

Explanation:
I’m going with B and C based on the following:
First requirement is “Members of the legal team must be able to conduct eDiscovery searches.” Second requirement employees must be notified when they send
email messages that contain confidential information” Option A Journaling doesn’t address either of these because at it’s core it’s recording communications based
on rules and creating reports. This cannot be configured to notify employees nor does it provide the legal team the ability to conduct eDiscovery searches.

Option B The Discovery Management role group allows administrators or USERS to perform searches of mailboxes in the Exchange Online organization. This
satisfies the first requirement so answer B is one of the correct answers.

Option C Data Loss Prevention Policies can be configured with a Policy Tip to notify the sender when they are sending confidential information.
Existing or custom DLP policy templates can be used to detect the presence of confidential information.

Option D Placing the executive mailboxes on In-Place Hold for 365 doesn’t meet either requirement. It doesn’t grant access to members of the legal team to
perform searches nor does it prevent/notify users when they are sending confidential information. It does allow you to perform both search and holds using the
same interface, but that wasn’t a requirement.

Option E Enabling archiving will store emails outside the the environment, but this will not help meet either requirement.
Option F Placing the executive mailboxes on Retention Hold for 365 doesn’t meet either requirement. It doesn’t grant access to members of the legal team to
perform searches nor does it prevent/notify users when they are sending confidential information.
