What is the primary purpose of a failover mechanism in a server environment?

To encrypt data at rest on the server

To distribute traffic evenly across all servers

To automatically switch operations to a standby server when the primary fails

To monitor server performance and alert administrators

Which mechanism is commonly used to detect a server failure and trigger failover?

A firewall rule that blocks traffic

Heartbeat signals sent between cluster nodes

A web application is deployed on three servers behind a load balancer. The load balancer is configured to distribute requests evenly among the servers. One server becomes unresponsive. What should the load balancer do to maintain service availability?

Automatically reboot the unresponsive server and then resume sending traffic

Stop sending traffic to the unresponsive server and distribute it among the remaining two

Send all traffic to the unresponsive server to force it to recover

Continue sending traffic to all three servers, including the unresponsive one
