(ISC)2 Certified in Cybersecurity Practice Exam

During which type of test might teams conduct a complete interruption to their normal business operations?

1. Simulation

2. Full interruption test

3. Walk-through

4. Read-through

The correct answer is: Full interruption test

The full interruption test is conducted when teams deliberately stop all normal business operations to assess the effectiveness of their disaster recovery or business continuity plans. This type of testing is critical because it allows organizations to evaluate their response to a significant disruption and determine how well they can recover essential functions during a real incident. During a full interruption test, participants engage in real-world scenarios that mimic a crisis, allowing them to practice their decision-making, communication, and recovery strategies under pressure. This testing type provides valuable insights into weaknesses in the current plans and helps organizations make necessary adjustments to ensure a more robust recovery process. In contrast, simulation tests typically involve scenario-based exercises without halting business operations, allowing teams to react to a crisis in a controlled environment. Walk-throughs involve discussing procedures and reviewing documentation with no actual disruption, while read-throughs usually consist of reviewing plans or protocols without any involvement from the operational environment. These alternatives do not entail the same level of interruption or practical experience as a full interruption test.
