2. Question 42 · 279 in bank

   A developer has written an After Update trigger on Account. A workflow rule and field update cause the trigger to repeatedly update the Account records. How should the developer handle the recursive trigger?

   • ADeactivate the trigger and move the logic into a Process or Flow
   • BDeactivate the workflow rule to prevent the field update from executing
   • CUse a static variable to prevent the trigger from executing more than once
   • DUse a global variable to prevent the trigger from executing more than once

   Show answer

   Answer: C

   Explanation

   A static variable is static only within the scope of the Apex transaction. It’s not static across the server or the entire organization. The value of a static variable persists within the context of a single transaction and is reset across transaction boundaries. For example, if an Apex DML request causes a trigger to fire multiple times, the static variables persist across these trigger invocations. To store information that is shared across instances of a class, use a static variable. All instances of the same class share a single copy of the static variable. For example, all triggers that a single transaction spawns can communicate with each other by viewing and updating static variables in a related class. A recursive trigger can use the value of a class variable to determine when to exit the recursion.

3. Question 43 · 279 in bank

   A company wants to create a dynamic survey that navigates users through a different series of questions based on their previous responses. What is the recommended solution to meet this requirement?

   • ADynamic Record Choice
   • BLightning Process Builder
   • CVisualforce and Apex
   • DCustom Lightning Application

   Show answer

   Answer: C

   Explanation

   I don't see A being a good answer. Ideally you would want to use flow, and although A is a piece of flow, it itself is not a complete solution. Of the options available, D would be best as it implements lightning components, which may have incorporated flow into it. However, it doesn't need to, it can stand alone and is better with being reactive and is better for mobile apps as well.
