Azure Front Door instance FD contains an origin group OG1. You need to configure OG1's health probe so it generates the least possible amount of probe traffic. Which HTTP method should the probe use?

The HEAD method is the most efficient choice for health probes because it requests only the headers of a resource, not the entire body. This minimizes the amount of data transferred and processed, thus generating the least possible probe traffic. GET requests retrieve the entire resource body, which is unnecessary for a health check and generates more traffic. CONNECT and TRACE methods are not typically used for standard health probes. CONNECT is for establishing a tunnel to the target, and TRACE is for debugging the request path, neither of which is suitable for simply checking origin health.
