Yes. You should sign the zone using 'pdnssec secure-zone example.com'
or leave as is to not use dnssec. Please make sure that the auth field
in table records is set properly.

> 2-When it is advised to roll over the keys in DNSSEC secured zones.DO i have to roll over the keys each time when i make changes to a secured zone data(like changing A records or Mx Records) or it will be automatically taken care by PDNS.Please elaborate this key roll over mechanism,a lot of confusion is there..

Taken from the manual:

"PowerDNS supports serving pre-signed zones, as well as online
('live') signed operations. In the last case, Signature Rollover and
Key Maintenance are fully managed by PowerDNS."

When you add / remove records, you need to call 'pdnssec rectify-zone
example.com' to make sure that the records orders are set properly.
This is important to use NSEC, that need the record before and after
to give a signed denial of existence. As far I remember, the field
content is not use in NSEC, so you can change this at will.

NSEC3 mitigate the zone listing issue, so I think that is a better
option. There is a pdns exclusive option called 'narrow', please read
the docs about it.

> 4-What is the NATIVE word in zone type.I understand master and slave,What NATIVE refers to.

NATIVE replication means any kind of replication outside DNS, like
database replication (my preferred). By your description, that's the
one you'll use.
