  1. What does SOAP define
    A. The overall structure of the XML message
    B. The conventions representing the remote procedure call in the XML message
    C. A binding to HTTP
    D. The conventions to wrap and send an error back to the seder
    E. All of the above


  2. SOAP with Attachments API for Java (SAAJ) is
    A. An API to produce, consume and manipulate the XML structure for the SOAP message programmatically
    B. An API to for XML messaging
    C. An API for remote procedure calls


  3. In WSDL a <port> refers to
    A. TCP/IP or UDP port on the server
    B. Reprsents the actual service inv used
    C. Exposes a <service> using a specific protocol binding


  4. UDDI is a registry and a repository
    A. True, because it also allows business documents like schemas and WSDL to be stored in it
    B. False, because the the actual content is never stored in UDDI.


  5. Java API for XML Parsing (JAXP) is
    A. A new XML parser implementation
    B. A standard XML parsing technique
    C. A standard XML API that can be used by developers with over an XML parser


  6. Java API for XML based RPC (JAX-RPC)
    A. Can be used to generate server side and client side Java (Web Service) code from a WSDL
    B. Can be used to generate a WSDL from Java (Web Service) code
    C. Both A and B


  7. A JAX-RPC client can invoke the service using
    A. Client side stubs automatically generated by a tool
    B. Dynamic Invocation Interface (DII)
    C. Dynamic proxies
    D. A, B, and C
    E. A client must invoke the service by looking up the Java interface in UDDI


  8. Java Web Services developed with JAX-RPC interoperate with .Net
    A. True, because they both generate the same SOAP message
    B. False, because one is written in Java and the other in C# etc.


  9. Java API for XML Registries (JAX-R) is an API
    A. To read and write to-from a UDDI registry using SOAP messages
    B. To read and write to-from an ebXML registry using SOAP messages
    C. A and B
