What is the polling interval for the Weekly graph?

The correct choice indicates that the polling interval for the Weekly graph is set to 60 minutes. This means that the system collects data and updates the graph every hour, allowing for a summary of data that reflects trends and patterns over the span of a week. A 60-minute interval is advantageous because it balances the need for timely data with system resource usage, ensuring that the graphical representation is both comprehensive and manageable.

In this context, each of the other choices suggests a shorter polling interval (30 minutes or 15 minutes) or restates the same duration in different wording (1 hour). However, implementing shorter intervals may lead to an unnecessary increase in data collection frequency, which can overload system resources and complicate the processing of trends over a longer period like a week. Thus, the choice of 60 minutes helps maintain a coherent overview of weekly data without overwhelming the system with excessive updates.
