Question 747 of 975
Deploy and manage a Microsoft 365 tenant →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is a recently deployed or updated DLP policy. This is correct because Microsoft 365 DLP policies evaluate content in near real-time, meaning any new or modified policy immediately enforces its rules on sharing actions, such as blocking a document containing a credit card number in OneDrive for Business. Since the document was shared successfully last week, the sudden block points directly to a policy change rather than a configuration error or user permission issue. On the MS-102 exam, this scenario tests your understanding of DLP policy lifecycle and enforcement timing, often appearing as a trap where candidates mistakenly blame user roles or sensitivity labels. Remember the key distinction: DLP policies are active the moment they are deployed, so a DLP policy blocking sharing after deployment is the most likely cause for a sudden change in behavior. Memory tip: “New policy, new block—deployment is the clock.”

MS-102 Deploy and manage a Microsoft 365 tenant Practice Question

This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

              "blockMessage": "Access blocked due to DLP policy"
            }
          }
        ]
      }
    ]
  }
}
```

The exhibit shows a DLP policy configuration. A user reports that they cannot share a document containing a credit card number from OneDrive for Business. However, the document was shared successfully last week. What is the most likely reason for the change?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The DLP policy was recently deployed or updated.

The most likely reason is that the DLP policy was recently deployed or updated. DLP policies in Microsoft 365 are evaluated in near real-time, and a newly deployed or modified policy will immediately enforce its rules on content sharing. Since the document was shared successfully last week, the policy change is the most plausible cause for the sudden block.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    The DLP policy was recently deployed or updated.

    Why this is correct

    The policy with block action was likely applied after the previous successful share.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The DLP policy requires administrator override for sharing.

    Why it's wrong here

    BlockAccess action does not provide an override; it simply blocks.

  • ✗

    The DLP policy is applied only to SharePoint Online, not OneDrive.

    Why it's wrong here

    The policy includes OneDriveForBusiness in locations.

  • ✗

    The DLP policy does not include Microsoft Teams.

    Why it's wrong here

    Teams is included, but irrelevant to OneDrive sharing.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may assume DLP policies are static and only apply to new content, but Microsoft 365 DLP policies are dynamic and can affect existing shares when deployed or updated.

Detailed technical explanation

How to think about this question

DLP policies in Microsoft 365 use policy tips and rule evaluation to inspect content for sensitive information types (e.g., credit card numbers) via the Microsoft 365 Compliance Center. When a policy is deployed or updated, it triggers a re-evaluation of all existing content and sharing actions, which can retroactively block previously allowed shares. The policy's action (e.g., 'Block people from sharing and restrict access') is enforced at the time of the sharing attempt, not based on historical permissions.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
