c/ Dynamic routes are added automatically.

d/ static routes are added automatically.

Answer 10

10

b/ The time required by protocols to update their forwarding tables after changes have occurred

c/ The time required for IDS to detect an attack

d/ The time required by switches to update their link status and go into forwarding state

Answer 12

12

b/ Routing convergence time is the time for all routers to update their routing tables (forwarding tables).

d/ None of the above

Answer 14

14
b/ RIPv1 sends broadcasts every 30 seconds and has an AD of 120. RIPv2 sends multicasts (224.0.0.9) every 30 seconds and also has an AD of 120.
