ISC2 CISSP Practice Question

The correct answer is a walkthrough test. This type of disaster recovery plan testing involves having the recovery team and business stakeholders review the disaster recovery procedures in detail, reviewing planned activities and ensuring the business requirements are met.

A tabletop exercise typically involves role-play of activities to disaster scenarios. This tests the ability of the participant to execute their roles, in order to uncover issues in the planned activities and documentation.

A simulation test would require actually executing recovery procedures in a test environment with real systems.

A parallel test involves running systems at the recovery site simultaneously with the production environment, which represents a much more advanced testing approach that involves actual system activation.
