[SLL] bind ttl question

[Adam Quigley]

Hypothetically, say you edit your zone file on the master and make a
mistake so that the zone file does not load.

How long does the data remain active on the slave?  My expectation is
that it would be up to the length of the TTL and then it's lost.  Is
that correct?

Also, is it possible to set a longer TTL on the slave that's different
from the master?
I'm not sure that even makes sense but somebody asked and I couldn't
say for sure.
