Which of the following would be most useful in helping to implement a workaround as quickly as possible?

A capacity database stores performance and utilization data used for capacity planning, not for storing or retrieving incident workarounds.

The Definitive Media Library (DML) is a secure store of authorized software versions and is unrelated to workaround documentation.

A request for change (RFC) is used to propose and authorize changes to the infrastructure and is not a tool for implementing workarounds.

A known error database is maintained by Problem Management and contains known error records that document the root cause analysis and, critically, the approved workaround for each issue. When an incident recurs, Service Desk staff can immediately retrieve and apply the workaround from the KEDB, significantly reducing resolution time.
