Select the scenario where the specification WS-MakeConnection should be used.

A.
To return responses back on a separate connection in a request and response flow. For example, enabling
WS-Addressing to specify a new address to deliver a response.

B.
To establish a connection for out-of-band communication with 3rd endpoint. For example, in using WSSecureConversation with another business endpoint, a token can be obtained from a 3rd party provider.

C.
To tunnel through a firewall and establish a back channel for messages to be sent to a previously unaddressable endpoint. For example, with WS-ReliableMessaging reestablishing a connection through a
firewall for acknowledgements.

D.
To create a separate connection to an endpoint to gain metadata about an endpoint prior to the initial
request. For example, creating a connection to a separate endpoint to retrieve WS-Policy information about
how to establish connectivity to a web services endpoint.
