Question 55

Given:

What will be the response to a HEAD request?

The findAll() method will be called and the employee list will be returned.

The findAll() method will be called and no employees will be returned.

No method will be invoked and no error will be returned.

No method will be invoked and a 404 error will be returned.

Correct Answer: B

For a HEAD request, if a corresponding GET method is defined in the resource class, it will usually be called to generate the response headers, but the response body will not be included. Here, the findAll() method will be called, but no employees will be returned in the response body.

B is the correct answer

orjavaOption: B

Answer B. HEAD by default invokes the implemented GET method (if present) and ignores the response entity (if set). This method can be used for obtaining metadata about the entity implied by the request without transferring the entity-body itself.
