Question

Holly would like to run an annual major disaster recovery test that is as thorough and realistic as possible. she also wants to ensure that there is no disruption of activity at the primary site. what option is best in this scenario? checklist test full interruption test parallel test simulation test

Answer 1

The option that will be best in this scenario would be a Parallel test. 
In a parallel test, same input will be entered in two different version of simulation.  By doing this, we could create multiple simulations to test several possibilities and reducing the total time needed at the same time. The downside is that this test exposes the tester to a high risk of making a mistake.
