Question 6

Rachel is responsible for managing the Consul implementation at Startup, Inc. She has federation configured between three Consul datacenters to ensure the highest of application availability. The three datacenters are named dc1, dc2, and dc3. For the service named web-app, she has written the prepared query (shown below) and created the prepared query in dc1.

In the event of a local failure, how many times will Consul reach out to query dc2 for an available web-app service?
