70-467 Question #141: Real Exam Question with Answer & Explanation
The correct answer is B: Write a script that calls the flushcache method to clear individual items from the SSRS cache.. To ensure SSRS reports never return purged data, the report cache must be programmatically cleared after midnight using the SSRS web service FlushCache method rather than relying on schedules that may be paused.
Question
A company runs SQL Server Database Engine and SQL Server Reporting Services (SSRS) in native mode. Reports are based on data that is cached in multiple shared datasets. Source data is purged each day at midnight for regulatory compliance purposes. The shared datasets may continue to cache data that should not be used in reports. Shared report schedules are often paused during nightly server maintenance windows. Reports must not return purged data. You need to create a fully automated solution to ensure that reports do not deliver purged data. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
Options
- ACreate a shared schedule. Configure the datasets to expire on the shared schedule.
- BWrite a script that calls the flushcache method to clear individual items from the SSRS cache.
- CCreate a SQL Server Agent job that uses a Transact-SQL (T-SQL) step to delete the data
- DRepublish the cached datasets by using SQL Server Data Tools.
Explanation
To ensure SSRS reports never return purged data, the report cache must be programmatically cleared after midnight using the SSRS web service FlushCache method rather than relying on schedules that may be paused.
Common mistakes.
- A. Shared schedules are explicitly stated to be paused during nightly maintenance windows, making schedule-based cache expiration unreliable for guaranteeing the cache is cleared after the midnight purge.
- C. A T-SQL step in a SQL Server Agent job can delete source data but has no mechanism to clear the SSRS report server cache, meaning reports could still return previously cached purged data.
- D. Republishing datasets via SQL Server Data Tools is a manual developer action, not a fully automated solution, and republishing does not reliably flush existing cached report data on a recurring basis.
Concept tested. SSRS shared dataset cache clearing via FlushCache web service
