Mark is responsible for managing his company's load balancer and wants to use a load-balancing scheduling technique that will take into account the current server load and active sessions. Which of the following techniques should he choose?

Least connection–based load balancing takes load into consideration and sends the next request to the server with the least number of active sessions. Round-robin simply distributes requests to each server in order, whereas weighted time uses health checks to determine which server responds the most quickly on an ongoing basis and then sends the traffic to that server. Finally, source IP hashing uses the source and destination IP addresses to generate a hash key and then uses that key to track sessions, allowing interrupted sessions to be reallocated to the same server, and thus allowing the sessions to continue.
