According to RFC:
In the case of message-oriented transports (such as UDP), if the
message has a Content-Length header field, the message body is
assumed to contain that many bytes. If there are additional bytes
in
the transport packet beyond the end of the body, they MUST be
discarded. If the transport packet ends before the end of the
message body, this is considered an error. If the message is a
response, it MUST be discarded. If the message is a request, the
element SHOULD generate a 400 (Bad Request) response. If the
message
has no Content-Length header field, the message body is assumed to
end at the end of the transport packet.
Cheers,
Vivek

Please note that ACK no response associated with it and hence a response
cannot be sent.
