A lot of servers in cluster

hi,
in the lesson 2.3-part 1 you say: "we want to give the mongo shell de name of all the servers in the cluster"
what happens if I have a lot of servers in my cluster?
Is it a good practice to specify all the servers in the connection?

thanks

No, its not mandatory with short srv connection string which works for MongoDB 3.6 version or later. Take a look at this:
