Answer: C

Explanation:

Based on the executable statement in the service file, all .hcl configuration files for Consul would be placed in /etc/consul.d/ . You can break up your desired Consul configurations across multiple .hcl files if you wish. It’s common to put the actual Consul configuration in a consul.hcl file while putting node_meta data into a node_meta.hcl file, therefore both will be read upon starting or refreshing the Consul service. This is because the executable statement in the service file is using -config-dir rather than pointing to a single file using -config-file.

ExecStart=/usr/local/bin/consul agent -config-dir=/etc/consul.d/
