Basics of OSPF

No Comments

OSPF is by far the most popular and important protocol in use today.

Most important features of OSPF:

  1. Its open source !
  2. Very fast convergence time, ( a tad close to even EIGRP )
  3. Link-state routing protocol
  4. Supports multiple, equal cost routes to the same destination
  5. Supports both IPv4 and IPv6
  6. Uses Dijkstra’s algorithm to find the shortest path tree and follows that by populating the routing table with resulting best path.
  7. Allows creation of areas and autonomous system
  8. Minimizes routing update traffic
  9. Supports VLSM/CIDR
  10. Unlimited hop count (unlike RIP)
  11. Supports Multi-vendor deployment.

Logistic Regression Interview Questions – Part 1

Q1. What is a logistic function? What is the range of values of a logistic function?
The logistic function is as defined below:

                                                                           f(z)=1(1+eāˆ’z)

The values of a logistic function will range from 0 to 1. The values of Z will vary from āˆ’āˆž to +āˆž.
