Question 6 of 28

      1st Answer Example

      "In my current work, I work with both main queue and private queue manged object contexts. It is important that I avoid non user related data processing on the main queue of an app that I am developing. In times where this has happened in the past, the user interface becomes unresponsive and crashes. As well, I work to avoid instances passing between the main and private queues to avoid corruption of data within the app."

      2nd Answer Example

      "Knowing that a managed object context's job is to manage a number of records within an app, my job is to successfully manage each object within the app and assign it to a correlating context within the app. I have to consider the persistent store coordinator and code the app to fetch requests from the correct one."
