A URL Filtering Caution action is designed for web-style requests where the user can be warned before proceeding. The supported request methods tested here are Connect, GET, and HEAD, which align with browser-driven web access and HTTPS tunnel establishment. Option A (Connect, Get, Head) is correct because those methods are valid for the Caution action.

Why the other options are incorrect:

B. Options, Delete, Put: OPTIONS, DELETE, and PUT are HTTP methods, but the canonical REST basics in the guide include GET, POST, PUT, and DELETE.

C. Get, Delete, Trace: TRACE is an HTTP diagnostic method and is not part of the standard REST method set emphasized for Zscaler automation.

D. Connect, Post, Put: CONNECT is proxy tunneling behavior. REST API basics focus on resource methods such as GET, POST, PUT, and DELETE.
