- A
Retention policy
Why wrong: Retention policies are time-based and can preserve or delete content, but they are not intended for indefinite preservation as required for legal holds. A litigation hold is specifically for legal preservation.
- B
Litigation hold
Litigation hold preserves all data indefinitely (or until the hold is removed) even if users delete items. It is the correct feature for legal preservation requirements.
- C
eDiscovery
Why wrong: eDiscovery is used to search, hold, and export content for legal cases, but it does not proactively preserve all content across the organization. Litigation hold is the preservation mechanism.
- D
Data Loss Prevention (DLP)
Why wrong: DLP policies prevent users from sharing sensitive information accidentally. They do not preserve content or prevent deletion. Litigation hold is required for preservation.

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
Litigation hold
Litigation hold is the correct feature because it preserves all mailbox and document content in its original state indefinitely until the hold is explicitly released. Unlike a retention policy, which can delete content after a specified period, Litigation hold ensures that even permanently deleted items are retained in the Recoverable Items folder, meeting the legal preservation requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a retention policy (which can preserve content but also delete it after a period) with Litigation hold, which is the only option that guarantees indefinite preservation regardless of user actions or time limits.
Detailed technical explanation
How to think about this question
Under the hood, Litigation hold places a mailbox on In-Place Hold, which moves deleted items to the Recoverable Items folder (specifically the Purges subfolder) and prevents the Managed Folder Assistant from purging them. This hold is applied at the mailbox level and can be combined with a retention policy for time-based retention, but when set to indefinite, it overrides any deletion actions. In a real-world scenario, if a user deletes a critical contract and then empties their Deleted Items, the content remains recoverable via eDiscovery until the hold is removed.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
