A developer who recently added message optimization support to the company's Web services is tasked with explaining how the next crop of WSIT client applications will use the feature. Which statement is true?
A. Client developers should have experience with the SAAJ and MIME types to use MTOM with the service.
B. The clients should use the service WSDL to discover and satisfy the interoperability requirements.
C. Adding message optimization is a manual step when the WSDL is available on HTTPS.
D. The encryption for optimization requires a client keystore.
A developer is analyzing an existing Web service with performance problems. The analysis reveals the service employs SOAP over HTTP. When the size of the encoded binary files grew with changing business requirements, the service slowed. What are two effective solutions for this problem? (Choose two.)
A. Separating the XML and binary content with WS-Filtering implemented in WSIT will improve efficiency.
B. XML documents larger than 1 KB with binary encoding should be optimized.
C. WS-Addressing can ease congestion by routing messages over other protocols.
D. For existing services, the most effective solution is to increase the available bandwidth.
E. MTOM can reduce both processing and bandwidth required by SOAP with attachments.
