A dynamic zone is a zone that allows dynamic updates, so the former. You 
don't need a .jnl file, and can remove it (provided you have flushed the 
updates and don't need the IXFR history) and it'll still be dynamic.

Another example, if you dnssec sign a zone, but leave it as static, then 
later set:

auto-dnssec maintain;


zone name {
   allow-update { ... };

...the zone will start to be "looked at" for DNSSEC signature 
maintenance as soon as you do an "rndc reconfig". It might take minutes, 
hours or days before a re-signing occurs, but it's dynamic immediately.

But I guess it's a matter of terminology.
