The correct answer is 'Roll back the database management system to the previous stable version' because restoring the previously working state is often the fastest way to recover from an issue introduced by a new update, especially in critical systems such as databases. 'Increase the compute resources allocated to the database to improve performance' might not solve the issue if it's related to the update itself, not to resource constraints. 'Redirect traffic to a secondary database until the issue is resolved' could potentially cause data inconsistencies if not correctly synchronized, and might not be an immediate remedy. 'Document the issue for analysis and continue monitoring for further disruptions' does not aim at solving the ongoing outage problem.
