Question

You are building a knowledge mining solution that will recognize Personally Identifiable Information (PII) by using Azure AI Search. You need to build an indexer pipeline that will flag the PII. The solution must minimize development effort. What should you include in the pipeline to flag the PII?

Options

  • Aan Azure AI Search built-in skill
  • Ban Azure function
  • Can Azure logic app
  • Dan Azure AI Search custom skill

Why each option

To recognize PII in an Azure AI Search indexer pipeline with minimal development effort, you should leverage the built-in PII detection skill.

Aan Azure AI Search built-in skill
Ban Azure function

An Azure Function would require custom code to implement PII detection, which increases development effort.

Can Azure logic app

An Azure Logic App would also require custom logic and integration, leading to more development effort than using a built-in skill.

Dan Azure AI Search custom skill

An Azure AI Search custom skill requires developing and deploying custom code to perform the PII detection, which contradicts the goal of minimizing development effort.
