Which option best ensures users always see fresh data in a real-time dashboard?

• A. Configure auto refresh for the dashboard.
• B. Use the pass-through identity option for the dashboard data source.
• C. Use a SQL query instead of KQL.
• D. Enable data caching to speed up responses.

Answer: (A)

Keeping the data current in a real-time dashboard comes down to refreshing the data source at regular intervals. Configuring auto refresh makes the dashboard re-execute its underlying queries on a set cadence, pulling in the latest data as soon as it’s available. This directly ensures users see fresh information instead of the previous values.

The other options don’t guarantee freshness: pass-through identity controls access but not how often data is refreshed; choosing SQL versus KQL changes the query language and doesn’t inherently affect how up-to-date the data is; and data caching serves responses faster but can return older results until the cache is refreshed, which undermines real-time freshness.
