Questions: Frequency of failure and network recovery time after a failure are measures of the of a network. A performance B reliability C security D feasibility

The answer is B: reliability.

Explanation for each option:

A. Performance: This typically refers to how well a network operates under normal conditions, including speed, throughput, and latency. While performance is important, it does not directly address failure frequency or recovery time.

B. Reliability: This is the correct answer. Reliability measures how consistently a network performs its intended functions without failure and how quickly it can recover from failures. Frequency of failure and recovery time are key aspects of network reliability.

C. Security: This pertains to the protection of the network from unauthorized access, attacks, and data breaches. While security is crucial, it does not directly relate to failure frequency or recovery time.

D. Feasibility: This refers to the practicality or possibility of implementing a network or a network feature. It is not related to the frequency of failures or recovery time.

In summary, the frequency of failure and network recovery time after a failure are measures of the reliability of a network.
