Administering Information Security in Microsoft 365 SC-401 Practice Test 25
Question 240
A legal advisor must send an encrypted Microsoft 365 email to an external counsel who does not use the same Microsoft tenant. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- The client or scanner service is installed, but no intended file or message was evaluated
- An authorized external test recipient opens protected mail using supported authentication
- An event is logged for a different repository or recipient population
- The protection configuration has been saved, with no test of user access or file labeling
Explanation
Correct Answer
B:An authorized external test recipient opens protected mail using supported authentication. This observation verifies the required control: Use Microsoft Purview Message Encryption with its supported external recipient experience. Message Encryption supports controlled access to encrypted messages for supported external recipients.
Incorrect Answers
A:Installed tooling is only a prerequisite; content processing has not been confirmed. In the present case the decisive acceptance evidence is: An authorized external test recipient opens protected mail using supported authentication
C:Evidence from another source does not exercise the stipulated file or email protection path. In the present case the decisive acceptance evidence is: An authorized external test recipient opens protected mail using supported authentication
D:Saved policy state does not show that access or classification actually worked. In the present case the decisive acceptance evidence is: An authorized external test recipient opens protected mail using supported authentication
Question 241
A security team wants to encrypt mail automatically when the message matches a custom patient identifier. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Rely on the user remembering to add a subject prefix each time
- Use a supported Exchange mail flow rule or DLP protection action that applies Microsoft Purview Message Encryption
- Turn on a SharePoint library default sensitivity label only
- Make the patient's domain an Entra dynamic group
Explanation
Correct Answer
B:Transport-based or DLP policy protection can activate on defined sensitive content conditions. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
A:A manually written prefix does not reliably invoke protected message encryption. Consequently it cannot satisfy the stated requirement.
C:A SharePoint default does not control Exchange email sending. Consequently it cannot satisfy the stated requirement.
D:Directory groups do not inspect message contents or apply encryption. Consequently it cannot satisfy the stated requirement.
Question 242
A security team wants to encrypt mail automatically when the message matches a custom patient identifier. During the pilot, an administrator instead implements this approach: Rely on the user remembering to add a subject prefix each time. The required outcome is not achieved. Which technical diagnosis BEST explains the failure?
- A SharePoint default does not control Exchange email sending
- Directory groups do not inspect message contents or apply encryption
- Transport-based or DLP policy protection can activate on defined sensitive content conditions
- A manually written prefix does not reliably invoke protected message encryption
Explanation
Correct Answer
D:A manually written prefix does not reliably invoke protected message encryption. This identifies the failure of the specific pilot implementation.
Incorrect Answers
A:A SharePoint default does not control Exchange email sending. That limitation concerns a different competing approach, not this pilot change.
B:Directory groups do not inspect message contents or apply encryption. This is a real constraint on a separate choice rather than the stated pilot implementation.
C:Transport-based or DLP policy protection can activate on defined sensitive content conditions. This describes the sound approach but does not diagnose why the observed alternative failed.
Question 243
A security team wants to encrypt mail automatically when the message matches a custom patient identifier. A change reviewer proposes Turn on a SharePoint library default sensitivity label only instead of Use a supported Exchange mail flow rule or DLP protection action that applies Microsoft Purview Message Encryption. Which assessment BEST explains the proposed design gap?
- A SharePoint default does not control Exchange email sending
- A manually written prefix does not reliably invoke protected message encryption
- Directory groups do not inspect message contents or apply encryption
- Transport-based or DLP policy protection can activate on defined sensitive content conditions
Explanation
Correct Answer
A:A SharePoint default does not control Exchange email sending. This deficiency directly applies to the suggested competing design.
Incorrect Answers
B:A manually written prefix does not reliably invoke protected message encryption. This limitation relates to a different rejected configuration.
C:Directory groups do not inspect message contents or apply encryption. This explains a different option rather than the actual proposal.
D:Transport-based or DLP policy protection can activate on defined sensitive content conditions. This supports the preferred design rather than evaluating the proposed alternative.
Question 244
A security team wants to encrypt mail automatically when the message matches a custom patient identifier. After configuring the selected control, what acceptance evidence MOST DIRECTLY establishes that the stated boundary works?
- The client or scanner service is installed, but no intended file or message was evaluated
- An event is logged for a different repository or recipient population
- A matched outbound test message is encrypted and a nonmatching control message is unaffected
- The protection configuration has been saved, with no test of user access or file labeling
Explanation
Correct Answer
C:A matched outbound test message is encrypted and a nonmatching control message is unaffected. This observation verifies the required control: Use a supported Exchange mail flow rule or DLP protection action that applies Microsoft Purview Message Encryption. Transport-based or DLP policy protection can activate on defined sensitive content conditions.
Incorrect Answers
A:Installed tooling is only a prerequisite; content processing has not been confirmed. In the present case the decisive acceptance evidence is: A matched outbound test message is encrypted and a nonmatching control message is unaffected
B:Evidence from another source does not exercise the stipulated file or email protection path. In the present case the decisive acceptance evidence is: A matched outbound test message is encrypted and a nonmatching control message is unaffected
D:Saved policy state does not show that access or classification actually worked. In the present case the decisive acceptance evidence is: A matched outbound test message is encrypted and a nonmatching control message is unaffected
Question 245
An organization must revoke access to a protected email after discovering it was sent to the wrong external recipient. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Use a supported Advanced Message Encryption capability for message access revocation when prerequisites permit
- Delete only the sender's Sent Items copy of the email
- Set the message importance flag to High
- Change the Exchange transport disclaimer after delivery
Explanation
Correct Answer
A:Advanced Message Encryption provides enhanced controls including revocation in supported scenarios. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
B:Removing the sender's copy does not revoke recipient access to an already delivered protected message. Consequently it cannot satisfy the stated requirement.
C:Importance metadata does not invalidate previously granted rights. Consequently it cannot satisfy the stated requirement.
D:A changed disclaimer does not revoke recipient message access. Consequently it cannot satisfy the stated requirement.

Question 249
A confidential email should become unavailable to outside recipients after a defined business period. Which Microsoft Purview configuration or security administration decision BEST meets the requirement?
- Use supported Advanced Message Encryption expiration controls for the protected message
- Set only the Outlook flag due date
- Use an eDiscovery case hold to disable recipient access
- Reduce the sender's Outlook cache size
Explanation
Correct Answer
A:Expiration governs a supported recipient's future ability to access protected content. This choice directly addresses the stated protected-data workflow.
Incorrect Answers
B:A follow-up reminder does not expire the recipient's rights. Consequently it cannot satisfy the stated requirement.
C:A legal hold preserves evidence rather than enforcing an expiration on reading. Consequently it cannot satisfy the stated requirement.
D:Local cache settings do not implement recipient-level expiry. Consequently it cannot satisfy the stated requirement.
