A developer new to Web services is researching how a client can connect to a service. It is clear that some models provide better abstraction while others offer more power when working with messages. What is the correct reason to choose the Dispatch interface?

Recently, the company has become concerned about the substantial cost of processing and message encryption with a PKI approach. What can be done to cut costs?

A. use MTOM to optimize the messages and provide data confidentiality via XML Digital Signature

B. because of the weak adoption of WS-SecureConversation on Java platforms, consider using Kerberos

C. use HTTPS as it is both economical and adequate

D. use WS-SecureConversation and MTOM to reduce the processing overhead

What are three best practices that can be implemented when generating WS-I Basic Profile compliant Web services? (Choose three.)
