Answer: A,B,C

Explanation:

Consul makes use of two different gossip pools. We refer to each pool as the LAN or WAN pool respectively. Each datacenter Consul operates in has a LAN gossip pool containing all members of the datacenter, both clients and servers. The LAN pool is used for a few purposes. Membership information allows clients to automatically discover servers, reducing the amount of configuration needed. The distributed failure detection allows the work of failure detection to be shared by the entire cluster instead

of concentrated on a few servers. Lastly, the gossip pool allows for reliable and fast event broadcasts. https://www.consul.io/docs/internals/gossip.html#gossip-in-consul
