Period of time when a service or machine is no longer accessible to customers.
What is downtime?
200
System design where multiple components or machines effectively operate as one.

Most common three methods to implement router redundancy protocols.
What are hot standby, virtual routers, and gateway load balancing?
300
Mitigation strategy that effectively means outsourcing the risk, and making it someone else's responsibility.
What is risk transfer?

What is an IDS?
300
Property of a system to continue operating if one or more components fail.
What is fault tolerance?
400
A type of threat to availability. Often managed by carefully picking the physical location of crucial operations like data centers
What are natural disasters?
400
Main constraint to be able to provide better location redundancy: i.e what enables us to go from point-in-time replication, to asynchronous, to synchronous.
