For Agentforce Service Agent implementations that involve sensitive data (e.g., healthcare records), Salesforce recommends combining standard topics for general use cases with custom topics and actions (built via Flow, Apex, or Prompt Builder) for privacy-sensitive operations.
This hybrid approach ensures compliance with HIPAA and organizational security policies while leveraging prebuilt, maintainable Service Agent capabilities.
Option B is unnecessarily restrictive and time-consuming.
Option C is inaccurate - standard actions do not automatically enforce advanced verification or compliance requirements.

Quick Actions in Lightning Experience allow admins to configure guided flows or prefilled forms that map case data to a new Knowledge Article. This is a standard and recommended approach to help service reps efficiently publish helpful content during case closure.
Option A (trigger) would require custom development and is unnecessary for this standard use case.
Option B (macro) automates console actions but cannot create Knowledge articles with mapped case data.

Explanation
Lightning Guided Engagement is a feature that allows you to create and display interactive guides for agents in the Lightning Service Console. Lightning Guided Engagement uses flows to define the steps and logic for each guide, such as displaying prompts, collecting inputs, updating records, or branching based on conditions. You can then use the Engagement component to embed the guides in the Service Console and trigger them based on record criteria, such as case status, priority, or product. Lightning Guided Engagement can help you configure the Lightning Service Console to support different troubleshooting steps for Tier 1 and Tier 2 support by creating different guides for each tier and displaying them based on the case record type or owner.
