An engineer has to settle two points about the section of the base document that sets out the components an implementation of the port-based protocol is made of. One is what that section demands of anyone writing such an implementation. The other concerns a host in the lab that has been given both of the roles the section names, and where the bands bearing those roles then stand. Which pair fits those two points?
