Consider a distributed system with at most k fail-stop processors and at most 1 fail-insane processor which exhibits Byzantine type of faults.

(a) At least how many processors are required to ensure that all healthy processors decide upon the same plan of action?

(b) Assume the maximum network delay is

d. The processor response time can be neglected. Design an agreement protocol among healthy processors.

(c) Assume a database is replicated among all the healthy processors in the system.
