The company wants to use the average response time of its application’s user interface as a basis for certain alerts. For this purpose, the following occurs:

1. Log every call start and finish date and time to a central analytics data store.
2. Compute response time uniformly as the difference between the start and finish date and time (A to H in the diagram).

Which computation represents the end-to-end response time from the user’s perspective?

## Correct Answer

_See scenario._

## Explanation

Selected Answer: A
I think A is right. Surely from the users perspective its the sum of all the operations?
