You have developed a Library service that provides an "AddBook" operation that is able to add a book record to a library system. This operation accepts a message based on an "AddBookRequest" element that contains book record details, such as its author and title. It then responds with a message based on the "AddBookResponse" element that acknowledges that the book was successfully added. Below is the current WSDL definition:
You are asked to extend this WSDL definition in order to add a new "DeleteBook" operation that is able to receive a request message based on the "DeleteBookRequest" element and reply with a response message based on the "DeleteBookResponse" element. Which of the following describes the minimum number of message, operation and "portType" elements that will need to be added in order to fulfill these requirements?

Nah, you actually need a portType for the new operation.

Wait, zero portType elements? That sounds off!

Agree, 2 messages and 1 operation seems right.
DE

I think it's just 1 operation element, right?

Definitely need 2 message elements for DeleteBook!

I feel like the answer might be A, since we need both messages and operations, but I’m not completely confident.

I'm a bit confused about the portType element. Do we need to add one for the new operation, or can we just use the existing one?
RA

I remember practicing a similar question, and I think we definitely need to add a new operation for DeleteBook.

I think we need to add at least 2 message elements for the request and response, but I'm not sure about the operations.

This seems like a good opportunity to apply my WSDL knowledge. I'll carefully review the existing WSDL and the requirements, and then determine the minimum changes needed to add the new operation.

I'm a little confused about the difference between message, operation, and portType elements. I'll need to refresh my understanding of WSDL before I can tackle this question.

Okay, let's think this through step-by-step. We need to add a new "DeleteBook" operation, which means we'll need to add new message, operation, and portType elements. I'm confident I can figure this out.

This looks like a straightforward WSDL extension question. I'll need to carefully analyze the existing WSDL and determine the minimum required changes to add the new "DeleteBook" operation.

Hmm, I'm a bit unsure about this one. I'll need to review the WSDL structure and the requirements closely to make sure I understand exactly what needs to be added.

Hmm, I'm a bit unsure about this one. I'm trying to think through the different options, but I'm not totally confident in my understanding of when an auditor would decrease the acceptable level of risk.

This question is a real head-scratcher. I might as well just pick A and hope for the best. At least it's not multiple choice!
FE

Let's go with A then, it's our best shot.
LA

A? Really? I was sure the answer was C. Ah well, I guess I'll have to trust the experts on this one.

Hmm, this is a tricky one. I'm going to have to think it through carefully, but I'm leaning towards A as the best answer.

I'm not sure about this one. The wording is a bit confusing, but I'll go with A since it seems to cover all the bases.
MA

The question seems straightforward. I think the answer is A, since we need to add 2 message elements, 2 operation elements, and 1 portType element to extend the WSDL definition.
FL

Exactly, it's important to have the right elements in place to support the new functionality.
FR

Adding those elements would ensure that the new DeleteBook operation can function properly within the library service.
TH
Theola

Yes, I agree. It makes sense that we would need 2 message elements, 2 operation elements, and 1 portType element for the new operation.
AL
Aliza

I think the answer is A as well. We definitely need to add those elements to extend the WSDL definition.
OC

But don't we need separate message elements for request and response in both operations?
TE

I disagree, I believe the answer is C) 1 'message' element, 1 'operation' element, 1 'portType' element.

I think the answer is A) 2 'message' elements, 2 'operation' elements, 1 'portType' element.
