Answer 1

As per 401 Unauthorized HTTP Status Code description:

The HTTP 401 Unauthorized client error status response code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.

your request seems to be missing credentials.

Depending on your application authentication implementation you should be able either to add HTTP Authorization Manager and configure it to match your application expectations or alternatively your test may miss (or have improperly working correlation), for instance it might be a dynamic request parameter, a HTTP Header or HTTP Cookie. In the latter case record your test once more, compare generated .jmx scripts, detect differences and work them around using JMeter's Post-Processors.

Answer 2

Adding HTTP Authorization Manager to Thread Group having username, password and domain (if applicable) to tests works
