Wait, wait, wait... 'fetch-host-keys'? Is this some kind of secret agent mission? I thought we were just adding a device to Cisco NSO! Oh well, I'll go with option B and hope I don't get any more spy-like surprises.

I'm pretty sure the correct answer is B. The question states that the device was added successfully, so the issue must be with the fetch-host-keys operation. Using POST instead of PUT should resolve the 405 error.

Hmm, the 405 error is a bit tricky. I guess the developers of this API don't want us to use the PUT method for the fetch-host-keys operation. Maybe they want us to use POST instead? Let's go with option B and see if that works.

But option A uses 'put' method, not 'post' as required in the question.

The 405 Method Not Allowed error code indicates that the HTTP method used (PUT or POST) is not allowed for the specified resource. Since the question mentions that the device was added successfully, the issue seems to be with the fetch-host-keys operation. Therefore, I believe the correct answer is B) response = requests.post(baseUriOperation + '/devices/device=ios-device/ssh/fetch-host-keys', auth=auth, headers=headers).
