Reveal correct answers
Correct answers: A, D
Explanation
The WAN pool is globally unique, as all servers should participate in the WAN pool regardless of datacenter. Membership information provided by the WAN pool allows servers to perform cross datacenter requests. The integrated failure detection allows Consul to gracefully handle an entire datacenter losing connectivity, or just a single server in a remote datacenter.
