if I understand the Forward Lookup Zones have SOA Record , I believe the Reverse Lookup Zone also has SOA.
I also am not clear with Delegation, if you can explain what it is.

Thank you

1) What is a SOA record. See Learnctx's first comment.

2) To see your SOA record...

One way...

3) if I understand the Forward Lookup Zones have SOA Record , I believe the Reverse Lookup Zone also has SOA.

PTR records (reverse lookup) are just another type of DNS record.

PTR != SOA

The way to think about this is one zone (collection of DNS records associated with a domain) has one SOA record.

4) I also am not clear with Delegation, if you can explain what it is.

Unsure what you're asking here.

Expand on your question, mentioning your exact concern or problem to resolve.

Delegations is some NS record redirecting further lookups to Another Name Server.
The zone for which this is done needs to have a SOA record.

(The delegation can be to the same server if needed).  SOA means all records in the tree below that one belong to it. ...
google does NOT manage the .COM zone,  it does manage the GOOGLE.COM zone.
The SOA record tells everyone concerned about this.

It also tells the read of the record  some more info: the Principal Name server for the zone (master), all others in the NS records are slaves.
The mail address to send cimplaints to (without a @ it is the first . in  its name)  a serial number and some other info for the slaves to sync to their master.
