Selected Answer: C

FortiWeb only routes connections for the pool to a backup server when all the other members of the server pool fail their server health check. The backup server mechanism does not work if you do not specify server health checks for the pool members.

A is correct The Server Pool in the exhibit is configured with a weight of 20 for server 1 and a weight of 60 for server 2. This means that server 1 will receive 20% of the sessions and server 2 will receive 75% of the sessions. The following formula is used to calculate the load balancing between servers in a Server Pool: weight_of_server_1 / (weight_of_server_1 + weight_of_server_2) In this case, the formula is: 20 / (20 + 60) = 20 / 80 = 0.25 = 25% Therefore, server 1 will receive 25% of the sessions and server 2 will receive 75% of the sessions.
