5. What type of exercise interrupts services to verify that all aspects of a business continuity plan are able to respond to a certain type of incident?

  • Tabletop exercise
  • Functional test
  • Operational exercise

Explanation: Operational exercises: At the most extreme are full operational exercises, or simulations. These are designed to interrupt services to verify that all aspects of a plan are in place and sufficient to respond to the type of incident that is being simulated.

6. Under which plan does personnel perform business processes in an alternate manner until normal operations resume?

  • Disaster recovery plan (DRP)
  • Business continuity plan (BCP)
  • Business impact analysis (BIA)

Explanation: Business continuity is one of the most important concepts in computer security. Having plans in place will ensure business continuity regardless of what may occur.
A business continuity plan (BCP) is a broader plan than a disaster recovery plan (DRP) because it can include getting critical systems to another location while the repair of the original facility is underway. In such a scenario, personnel continues to perform all business processes in an alternate manner until normal operations resume.

The steps in the chain of custody must be carefully followed to avoid allegations of tampering.

  • A cardboard box
  • A plastic container

Explanation: Media containing digital evidence should not be stored in plastic containers, because plastic can produce or convey static electricity.

9. Is the following statement true or false?
‘You should always follow the order of volatility when collecting evidence, proceeding from the least volatile evidence to the most volatile.’

  • True
  • False

Explanation: You should always follow the order of volatility during the collection process, by proceeding from the most volatile evidence to the least volatile.

10. When acquiring evidence, what can you use to validate that data and applications were not modified after analysis?

  • Network and traffic logs
  • Hashes or checksums of data
  • Time offset data

Explanation: Hashes or checksums of all data and applications before and after any analysis, to validate that they were not modified.
