DP-300 Plan and implement data platform resources Practice Question
A company uses Azure SQL Managed Instance for its line-of-business applications. They need to ensure that backups are retained for 35 days for compliance purposes. Which configuration should the DBA set?
⚠ Common exam trap
Many exam-takers confuse long-term retention (LTR) with the standard backup retention period, assuming LTR is required for any retention beyond the default 7 days, when in fact the 35-day maximum is configurable directly in the backup settings.
