    1) D The question just said it is for "Apex helper class" and did not mention VF page, so "Limits.getDMLRows() " should be correct.

    2) AD

    3) AC In Salesforce, Dashboard can take VF Page as a component

    4) B

    I'm not sure ⌗1 is A.  I don't think you can give a "clean" error after the DML has been exceeded.  I think the answer is D.

    Hi @Sahasra

    1)A--------> we could use ApexMessage.Message() method in the controller and set the desired error message in order to display this error messages to the users on the VF Page we could use <apex:pageMessages /> tag in VF page code

    2) A and B----------->  Go to quick find box in your org, type debug logs,hopefully you would be seeing almost everything that you are looking for

    4) B

    I have answered based on my working experience,

    Thanks
