What the record modes?

The standard mode is just a regular record (A, CNAME, etc) that points to the destination IP or fully qualified domain name.

The failover mode is for DNS Failover configuration used in conjunction with a configured Constellix Sonar check.

The pools mode allows administrators to define sets (pools) of IP's to round robin, removing hosts automatically that aren't responding within a pool, and failover between sets of pools based on a minimum number of available IP's within a pool. This functionality combines many features together to maximize redundancy of hosts and speed up availability of services.

Round robin with failover allows you to define multiple hosts to split traffic between and failover between them if one is down. For example A fails to B and B to A, but if both A and B are up, traffic is split 50/50 between the two.
