No, the client sets the desired replication factor requirement when it
invokes the create functions at the NameNode. If not present
explicitly in the invocation call, a default from the client is sent
(which is why setting dfs.replication at a specific client works).

No, the metadata signifying the value of replication is held at the
file inode alone, the dirs are not aware/do not maintain replication
counts of the files under them.
