A network administrator modified an OSPF-enabled router to have a hello timer setting of 20 seconds. What is the new dead interval time setting by default?

  • 40 seconds
  • 60 seconds
  • 80 seconds
  • 100 seconds
Explanation & Hint:

In OSPF (Open Shortest Path First), the dead interval is typically set to four times the hello interval by default. If a network administrator modified an OSPF-enabled router to have a hello timer setting of 20 seconds, then the new dead interval time, by default, would be:

20 seconds (hello interval) * 4 = 80 seconds

So, the new dead interval time setting by default would be 80 seconds.
