Microsoft SC-401 Exam With Confidence Using Practice Dumps

To allow users to apply retention labels to individual documents in Microsoft SharePoint libraries, you need to create a retention label and publish the label.

In Microsoft Purview, retention labels define how long content should be retained or deleted. You must first create a label that specifies the retention rules. After creating the label, you must publish it so that it becomes available for users in SharePoint document libraries. Once published, users can manually apply the retention label to individual documents.

A trainable classifier in Microsoft Purview is used to automatically identify and classify unstructured data based on content patterns. The classifier can be used in:

1. Retention Labels (Label2) → Supported

● Trainable classifiers can be linked to retention labels to automatically classify and apply retention policies to documents.

2. Retention Label Policies (Policy1) → Supported

● Retention label policies define how and where retention labels are applied, including automatically using trainable classifiers.

3. Data Loss Prevention (DLP) Policies (DLP1) → Supported

● Trainable classifiers can be used in DLP policies to detect and protect sensitive content automatically.

To detect and protect confidential documents, we need a custom rule to identify project codes that start with 999 (since they are classified as confidential).

Box 1: A Sensitive Info Type (SIT) allows Microsoft Purview DLP policies to recognize structured data (e.g., project codes). DLP policies require a sensitive info type to detect content based on patterns, keywords, or dictionary terms. A sensitivity label alone does not define detection logic—it is used for classification and protection after content is identified.

Box 2: Since project codes follow a structured 10-digit pattern, we should use a Regular Expression (Regex) to match project codes that start with 999.

Example Regex pattern:

999\d{7}

This pattern detects a 10-digit number starting with "999".
