CACHING DATA WITH DATA PAGES
This quiz question # 2 has an answer that is inconsistent with the Exercise lesson.
See attatched print screens...
When the page is one hour old, whether created or accessed it should be reloaded...?
Please explain WHY the quiz is stating ONLY when the data page is stale after creation when the study material DOES NOT state this.
Thanks

While I have had some struggles myself making the leap from a given exercise to the questions asked in the quizzes, this may help. The answer you are looking for is on page 403 of the pdf version of the student guide. I am pasting the paragraph that addresses the question you have referenced:
"Every data page defines a refresh strategy. The refresh strategy defines when the data page is considered stale and needs to be reloaded. Data pages are created and updated on demand. Even if a data page is considered stale, the page is never reloaded until it is referenced. The available refresh strategy options depend on the scope of the page."
Hope that helps.
