Question # 7

You are creating documentation for a new wireless solution that is deployed in the organization. Why is it important to document APIs in use within the system?

A.

If APIs are in use, it typically indicates the use of custom scripts or application code. Future support will be easier when the APIs in use are documented.

B.

The APIs in use will not function without this documentation.The documentation is linked to the executable process of the APIs.

C.

If APIs are in use, it typically indicates that the vendor has not provided ideal support. Without documentation, you cannot prove this reality for a discount.

D.

It allows future support to implement APIs that have not been used at the time of deployment.
