Signalling and communicationQuestion 147 of 1506

A master/slave network is very deterministic. What is its main fault-tolerance weakness?

  1. If the master fails, no other node gets permission to transmit
  2. Slave nodes collide with each other often
  3. The network speed depends on random delay timers in each node
  4. Tokens can be duplicated
Show answer

Correct answer: If the master fails, no other node gets permission to transmit

The whole system fails.
