Which of the following statements is true? Select the correct answer.

Question

Options

• AWS-Policy allows for the definition of policies that can be ignored by service consumers.
• BWS-Policy allows for the definition of procedure-related policies that can be attached to database
• CWS-Policy allows for the definition of MEP policies that are limited to outbound MEPs only.
• DNone of these statements are true.

• A
  92% (35)
• C
  3% (1)
• D
  5% (2)

Explanation

Option A is correct because WS-Policy supports the concept of optional policy assertions using the wsp:Optional attribute. This explicitly allows service consumers to ignore marked assertions without violating the policy - making the statement accurate as written.

Option B is wrong because WS-Policy has nothing to do with database procedures. Its policies attach to WSDL elements (services, bindings, operations, messages), not databases - the description mixes up WS-Policy with something like stored procedure governance.

Option C is wrong because WS-Policy places no such restriction on Message Exchange Patterns (MEPs). Policies can apply to inbound, outbound, or any MEP - not outbound only. The limitation described in C does not exist in the specification.

Memory tip: Think of WS-Policy like a restaurant menu with optional items - consumers can skip the optional policies (like skipping a side dish) and still be valid customers. The key word to associate is "optional" = can be ignored.
