This network passes data most of the time, but sometimes for reasons unknown to the junior network engineer in charge of monitoring the network, the core router often crashes. What is the characteristic that is violated?

A. Failure

B. Availability

C. Performance

D. Manageability

E. Scalability

The characteristic that is violated is Availability.

Explanation:

The network is passing data at mostly, it means performance is good. Junior network engineer is doing his job well then there is minimum chance of network failure or lack of manageability. The scalability; range of computing capabilties can be managed by the engineer. However, sometimes the core router might get crashed due to unavailability of the network that is not under the control of the engineer.
