Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Incident response stage in which the affected system(s) are restored to operational status. typically the business unit responsible for the system will dictate when the system will go back online. close monitoring is necessary

4. Failover cluster - employs multiple systems that are already installed - configured - and plugged in - such that if a failover causes one of the systems to fail - then the other can be seamlessly leveraged to maintain the availability of the service
