Exam Certified Platform Developer II topic 1 question 16 discussion

This should be 'C'. D option will update all the Account records instead of only the required ones.

B seems to be the right answer. It has the status in the query, and does the update as required. Not sure why no one is considering B and not saying why it's wrong either!

chatgpt says so :)

Answer is B

I tested the A solution and it works correctly

A. Is correct and more optimized. With .containsKey null values are avoided. B. Is wrong because the soql is filtering by Status instead of Type, It wont receive any result C. Is correct but it less maintenable and less flexible. Mapping is a better choice. D. Is wrong because it will update all accounts with null types to Pending. In my opinion the option B was badly written in examtopics and the original exam had the soql filtering by Type which would make it perfect in terms of optimization, but in this context, A should be the correct anwser.

Should be C

It is B

Write answer is C, A and D can changing Accounts with other Types and B will give you not correct data because of wrong SOQL

Since the questoin mentioned "No other changes to data should be made", ALL answers are wrong. Query should filter Account Type IN ('Customer', 'Prospect') or should filter result if Type == Customer or Type == Prospect and only add them to the list to be updated.

Should be C. A will also update account with type = null or empty

All the answers are incorrect because "Status " is not in SOQL. Other than that "B" is the correct answer

Only A does it all. C doesn't do second half of the task.

Answer D cannot be right. This solution will fail at the 3rd line, because you would set the ‘Pending’ status for every other type than customer. Also e.g. for ‘Agency’. This means for type ‘Customer’ you would set the status ‘Active’ correctly, but for EVERY other type (Prospect, but ALSO other types) you would set the status to ‘Pending’. Answer B can’t be right as well, because the WHERE clause is filtering for “Status” IN the map’s keySet, means it checks for a status with values “Customer” or “Prospect” (which are the Account’s Type values). Therefore it will not return any account records to iterate over. C looks to me the correct answer

Its option B as the Account SOQL query filter only the required fields

This should be A. Option C will increase the APEX CPU Time more than A.

Does anyone notice that status wasn't included in any of the SELECT? Update on any of the choices should not work.
