A server administrator needs to set up active-passive load balancing for an environment with multiple network paths. The traffic should be directed to one path and switched only in the event that the original path becomes unavailable. Which of the following describes this scenario?
In an active-passive load balancing configuration, one path (or server) handles all the traffic while the other remains in standby mode, ready to take over if the active path becomes unavailable. This setup is typically monitored via a heartbeat mechanism, where the standby server checks the availability of the active server and takes over when it detects a failure.
Heartbeat (Answer B): This term refers to the monitoring process that checks the availability of the active path in an active-passive configuration.
Most recently used (Option A): This describes a load-balancing method where the most recently used path or server is prioritized, but it doesn't describe an active-passive setup.
Link aggregation (Option C): This refers to combining multiple network connections for increased throughput, not for failover purposes.
Round robin (Option D): This load-balancing method alternates traffic between all available paths, which doesn't match the active-passive description.
