Q

Which is not an advantage for static routes?

  • On larger networks static routing is very easy to set up
  • System Administrator has full control over all routing behavior on the network
  • On smaller networks static routing is very easy to set up
  • CPU does not have heavy workload due to no traffic that has to be passed to other routers
