HOTSPOT - (Topic 2)
You have a Microsoft 365 E5 subscription.
You need to identify documents that contain patent application numbers containing the letters PA followed by eight digits, for example, PA 12345678. The solution must minimize administrative effort.
What should you do? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Solution:
Box 1: Since you are looking for a specific pattern (PA followed by eight digits, e.g., PA 12345678), the best classification method is Sensitive Info Type. Sensitive Info Types allow pattern-based matching to identify structured data. Exact Data Match (EDM) is not needed because you're not comparing against a fixed dataset. Trainable classifier is not appropriate because this is a structured pattern, not an unstructured document classification.
Box 2: Since PA 12345678 follows a structured pattern, the most effective method is Regular Expression (Regex). A Regular Expression (Regex) can be written to match "PA" followed by exactly eight digits (e.g., PAsd{8}). Keyword dictionary is not ideal because it works for predefined words, not number patterns. Function is unnecessary because there is no need for checksum validation or predefined validation rules.

Does this meet the goal?

1. A. Yes
2. B. No

Correct Answer: A
