the default file name is named_dump.db
If your named.conf has this bit
options {
  directory "/var/cache/bind";
    # working directory

then "rndc dumpdb -zones" creates the file /var/cache/bind/named_dump.db

If your named.conf has this bit
options {
  dump-file "/tmp/cache_dump.db";

then "rndc dumpdb -zones" creates the file /tmp/cache_dump.db

Yes, it would be nice if that was added
