1. After setting up two servers with heartbeat, use ping/apache to test the setup, remove the LAN cable on the primary server then observe what will happen and what is the average delay before the service responds again. (You need to get the average so you need to test the setup at least thrice). What value on the ha.cf matched or is near on the result of your investigation?

2. Setup three to four servers with heartbeat on each server. The set up must have a primary server and the rest are secondary/slave servers. Remove the LAN cable on the primary server, what will happen next. Also observe the response time of the secondary server.
3. From your latest set up, remove the LAN Cable from the slave that responded earlier and observe what will happen
Some more screenshots
The average delay time before the service responds for all servers is about 0.948 for the three servers, with each of the servers when removing the LAN the server responds a bit slower in comparison with the primary server
