What is the retention period for historical data in Account Usage compared to Information Schema?

• A. Account Usage retains 1 year; Information Schema up to 6 months
• B. Account Usage retains 6 months; Information Schema 1 year
• C. Account Usage 2 years; Information Schema 1 year
• D. Account Usage 3 months; Information Schema 9 months

Answer: (A)

Account Usage is designed to support governance and auditing over a longer period, so it preserves historical data for about a year. Information Schema, on the other hand, is focused on current metadata and light-weight observations, with data retained for up to six months. That combination makes Account Usage the go-to source when you need older history, while Information Schema is suitable for more recent metadata.
