An administrator is configuring keepalived on two LVS directors to provide a redundant virtual IP for a load-balanced web service. The primary director must own the VIP whenever it is healthy, and the backup should take over only if the primary fails. Which VRRP configuration parameter should be set on the primary to ensure it always wins when both nodes are healthy?

A shorter preempt delay than the backup

A higher priority value than the backup

The same virtual router ID as the backup

A lower advert interval than the backup

An administrator configures HAProxy with two backends: one for API traffic and one for static content. They want to route requests based on the URL path, but they also need to preserve the original client IP address in the backend logs. Which HAProxy configuration should be used?

Use balance source in the frontend and cookie in the backend

Use ACLs with use_backend for path-based routing, and enable option forwardfor in the frontend

Use option redispatch in the backend and timeout connect in the frontend

Use a listen section with balance roundrobin and option httpchk

What is the primary function of ldirectord in a load-balanced cluster?

To balance traffic using HTTP cookies

To provide a virtual IP for VRRP failover

To monitor backend servers and update IPVS rules based on their health status

To encrypt traffic between the director and real servers

An administrator configures HAProxy to terminate TLS connections and forward plain HTTP to backend servers. Which HAProxy configuration section should be used to define the TLS certificate and the frontend listener?

backend section with server directive

frontend section with bind directive specifying the certificate

global section with maxconn directive

listen section with balance directive
