Which of the following are characteristics of a High Availability (HA) network?

• A. Faults cannot occur frequently.
• B. Faults can be recovered rapidly.
• C. No faults occur.
• D. Services can only be restored manually when faults occur.

Answer: (A)

In a High Availability (HA) network, the primary goal is to ensure that services remain operational and accessible even in the event of failures. Among the characteristics listed, the one that aligns best with the principles of HA networks is that faults can be recovered rapidly. High Availability systems are designed with redundancy and failover mechanisms to minimize downtime. This means that when a fault does occur, the systems can quickly switch to backup resources or reroute processes to maintain service continuity. The essence of HA is not that faults never happen or that they cannot occur frequently, but rather that any faults that do occur should not lead to significant service interruptions. The idea that "no faults occur" is unrealistic in any network environment, as faults are inherent risks in complex systems. Furthermore, relying exclusively on manual restoration when faults occur contradicts the efficiency and automation that HA networks strive for. Such manual interventions could lead to extended downtimes, which goes against the very principle of maintaining high availability. Thus, a true characteristic of HA networks is their capacity to recover from faults rapidly, ensuring that users experience minimal disruption in services.
