CompTIA Security+ SY0-701 Practice Question

Availability refers to the concept that systems, functions, or data should be accessible when required by the user. High availability systems are designed to be operational and available for use a very high percentage of the time, often through redundant or fault-tolerant components. An 'Air-gapped network' refers to a security measure to physically isolate a computer or network from other networks, including the internet, which doesn't directly pertain to its ability to be available. 'Ease of recovery' is associated with the ability to restore system capabilities or access to data after a disruption, not the continuous availability. 'Real-time processing' refers to the capability of systems to process data as it comes in without delay, which is not exclusively about the system’s ability to be continuously operational and available.
