No, what you show below only comprises the contents of the iskl.edu.my 
zone. The child zone lc.iskl.edu.my is delegated via NS records and 
necessary "glue" A records. But you show nothing from the lc.iskl.edu.my 
subdomain that would be considered "beneath the zone cut", e.g. 
www.lc.iskl.edu.my.

P.S. I notice that the 203.106.230.5 nameserver is in violation of the 
RFCs because it has a duplicate A record for tm.lc.iskl.edu.my. This 
implies that it is not running a BIND implementation (or a very old one, 
perhaps). The zone also contains a "chained" alias from ps.iskl.edu.my 
to powerschool.iskl.edu.my. But the specific problem you complained 
about -- parent and child data in the same zone -- is not evident.

P.P.S. Hopefully you didn't expose anything security-sensitive via that 
"encoded" CNAME pointing to google.com.
