Microsoft 365 Certified: Administrator ExpertImplement and manage Microsoft Purview complianceEasy

A financial services company uses Microsoft 365. Due to strict regulatory requirements, they must ensure that all email communications related to client financial transactions are preserved for 10 years and are immutable. Additionally, these communications must be easily discoverable by the legal department when required. Which Microsoft Purview feature should the administrator implement to meet these requirements most efficiently?

  1. AInformation Barriers (IB) policies
  2. BData Loss Prevention (DLP) policies
  3. CRetention policies with a preservation lock
  4. DCommunication Compliance policies
Show answer & explanation

Correct answer: C. Retention policies with a preservation lock

Retention policies with a preservation lock ensure that content is retained for a specified period and cannot be deleted or modified, fulfilling the immutability and preservation requirements. This also makes the content discoverable.

Why the other options are wrong

  • A. Information Barriers prevent unauthorized communication between specific user groups, not long-term immutable content preservation.
  • B. DLP policies focus on preventing sensitive data from leaving the organization, not on long-term immutable retention.
  • D. Communication Compliance policies monitor communications for policy violations, but do not inherently provide immutable long-term retention.

Retention Policy with Preservation Lock

A Microsoft Purview retention policy configured with a preservation lock ensures that content cannot be deleted or modified by anyone, including administrators, for the duration of the policy.

  • Ensures immutability of data.
  • Prevents content deletion/modification.
  • Meets strict regulatory compliance for data preservation.

Memory trick: Lock your records tight, for years they must stay right.
