How often is the WADS supposed to change over?

• A. Every 60 seconds
• B. Every 15 seconds
• C. Every 5 minutes
• D. Every 30 seconds

Answer: (D)

The update cadence is chosen to balance timely information with system stability. Changing every 30 seconds keeps the data fresh enough for practical monitoring and decision-making, without causing excessive overhead from too-frequent updates.

If it changed every 60 seconds, information could become stale too quickly, reducing responsiveness. If it updated every 15 seconds, the system might handle more frequent churn and potential overhead without a clear gain in value. Waiting 5 minutes would leave data outdated for a long period, defeating the purpose of keeping things current. Therefore, 30 seconds is the most sensible compromise, providing reasonably current data with manageable resource use.
