Exam DP-203 topic 2 question 39 discussion

Respuesta Correcta: Hopping

Hopping is right

The secret here is "last/previous five minutes every minute". If they were 5x5 or "non repeated counts" or no-overlap, it could be both Hop and Tumbling, being Tumbling the most appropriate.

And why not sliding?

Hopping

D is correct answer

A hopping window would not be the best option for this scenario because it does not allow you to set a sliding interval that is less than the window size. In a hopping window, the window size is fixed, and the window "hops" forward by a specified number of intervals. For example, if you set a hopping window size of five minutes and a hop size of one minute, then the first window would include data from the first five minutes, the second window would include data from the second through sixth minutes, the third window would include data from the third through seventh minutes, and so on. In this scenario, if you set the hopping window size to five minutes, you would only output the count of records every five minutes, which does not meet the requirement of outputting the count of records every minute. Therefore, a sliding window would be a better choice as it allows you to output data at smaller sliding intervals, which is required in this scenario.

Why shouldn't it be sliding?
