Which is NOT a valid option to execute a function deployed on Oracle Functions?

C.

The correct answer is option C, "Invoke from Docker CLI," as it is not a valid option to execute a function deployed on Oracle Functions.

Explanation: Oracle Functions is a serverless compute platform that allows developers to create and deploy event-driven, serverless functions. Once a function is deployed, it can be invoked using various methods, including:

A. Send a signed HTTP request to the function's invoke endpoint: When you create a function, Oracle Functions generates a unique invoke endpoint for the function. You can send an HTTP request to this endpoint to invoke the function. The request must be signed with an Oracle Cloud Infrastructure user's credentials to authenticate the request.

B. Invoke from Oracle Cloud Infrastructure CLI: You can use the Oracle Cloud Infrastructure CLI to invoke a function. You need to provide the function's OCID (Oracle Cloud Identifier) and input parameters to execute the function.

D. Trigger by an event in Oracle Cloud Infrastructure Events service: You can set up a trigger for a function in Oracle Cloud Infrastructure Events service. When the event occurs, the function is automatically executed.

E. Invoke from Fn Project CLI: You can use the Fn Project CLI to invoke a function. You need to provide the function's endpoint URL and input parameters to execute the function.

C. Invoke from Docker CLI: This option is not valid to execute a function deployed on Oracle Functions. Docker is a containerization technology, and Oracle Functions does not use Docker to deploy functions.

In conclusion, options A, B, D, and E are valid options to execute a function deployed on Oracle Functions, while option C is not valid.
