A company runs a web application with two backend servers. They want HAProxy to distribute incoming requests evenly between the two servers, but they also want to ensure that if one server fails, all traffic is sent to the remaining server. Which HAProxy configuration should be used?

balance first with option redispatch

balance roundrobin with option httpchk

balance source with timeout connect

An administrator configures HAProxy to route traffic based on the URL path. Requests to /api/ should go to a backend named api_servers, and all other requests should go to a backend named web_servers. Which HAProxy configuration element should be used in the frontend to make this routing decision?

listen section with balance roundrobin

A team uses LVS in tunneling mode (TUN) to load balance traffic to real servers located in different data centers. What must be configured on the real servers to accept the encapsulated packets from the director?

The VIP must be configured on a loopback interface, and IP forwarding must be enabled

The real servers must be on the same L2 segment as the director

The default gateway must point to the director's IP

The real servers must have a public IP on their external interface
