A , B & D is correct answers.

B, C, and E are capabilities of Salesforce outbound messaging.

B. Provide a session ID as part of the outbound message - The session ID is used as a way for the recipient to track the source of the outbound message and to ensure that it is coming from a valid source.

C. Define a WSDL based upon 2 objects related via Master-Details relationship - Salesforce can create a WSDL that represents the data model of the objects and their relationship in the organization, allowing external systems to easily consume and understand the data being sent.

E. Define a custom WSDL based upon an Apex Interface class definition - This allows developers to define custom messaging interfaces in Apex and generate WSDLs to be used by external systems. This provides greater control and flexibility over the structure and content of the outbound messages.

A and D are not capabilities of Salesforce outbound messaging because:

A. Building integration components without the Use of APEX is not specific to outbound messaging. Salesforce provides multiple ways to build integration components, including Apex, which can be used in combination with outbound messaging.

D. Repeatedly sending a SOAP notification for up to 24 hours until an acknowledgement is received is not a capability provided by Salesforce outbound messaging. Outbound messaging is designed to send a single message to an external system and does not include any retry logic....
