Exam MB-200 topic 10 question 14 discussion

Answer is: D - because the case study says: modification to the Patient form needs to be tested immediately, but the Invoice form modification needs to be tested the following week. Exist in sandbox only one solution that include both Patient and Invoice therefore you can only remove directly the field on QA

I think the correct answer should be A, since if you deploy a next time, the field will be recreated and therefore undoing your change. If using managed solutions, this will also delete the field form QA environment.

I would pick C - remove the field from the solution in QA Why? 1. I would remove and not delete because the field is only redundant in the patient form, the field might still be useful in another form. So I guess remove field from the form in the solution is what is implied. 2. I picked QA because, testing occurs in QA and solutions in QA will be the one to be imported into the production instance where it will be used by all, so why should I make the changes in Sandbox?

Status is a system field when you create a custom entity. So you wouldn't be able to delete. So it's either removing field from QA or Sandbox depending on which you think is correct. Moreover, "There is one solution in the Sandbox environment containing modifications to the Patient and Invoice forms" so removing the field from here would be sufficient. I think it's implied that you would be removing the field from the form however poorly worded question I guess (This justification only works with B though)

The best answer is D because: 1. The data is redundant and therefore does NOT need to be retained. 2. "All changes are first created in the Sandbox environment and then imported into the QA environment for testing."

B is 100% the correct answer. "All changes are first created in the Sandbox environment and then imported into the QA environment for testing." = SANDBOX remove the field rather than delete to keep the data

Deleting field deletes the data: https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/customize/delete-fields Requirement is for the data to be retained. Removing field I assume applies to the removing field from the form only. Hence, I think the "remove" word is more applicable here. Now in regards to "sandbox" or "QA". There is no mentioning of the managed solution, and requirement is to be tested ASAP. So I would make the changes in the QA right away so they can test.

It states that the change about the patient has to be tested immediately, so the answer should be to delete it directly in QA. Obviously, if then is not deleted also from sandbox the field we'll be created again, but it seems that "resolve" in this case means to have a successful test.

"Testers only have access to the QA environment where testing occurs. Doctors and nurses enter patient, billing, diagnostic, and other information directly." Nurse, doesn't has access to the Sandbox. So, it is should be

I think B is a correct answer

All changes are first created in the Sandbox environment and then imported into the QA environment for testing, So the best option would be: B - Remove the field from the solution in the Sandbox environment.
