202-450 Exam - Question 95


A zone file contains the following lines:

and is included in the BIND configuration using this configuration stanza:

Which problem is contained in this configuration?

Show Answer
Correct Answer: BC

The problem in this configuration is that the zone cannot contain records for a name which is outside the zone's hierarchy. The zone defined is for 'example.com,' but the record 'host2.example.org' is included in the zone. Since 'host2.example.org' belongs to the 'example.org' domain and not 'example.com,' it should not be present in this zone file. This is a misconfiguration as the zone file should only contain records within its specified domain hierarchy.

I think its B. Shouldn't have records for a different domain. ( Never saw BIND complain about $ORIGIN in a zone). But not 100% sure.

The problem in this configuration is: B. The zone cannot contain records for a name which is outside the zone's hierarchy. In this configuration, the zone is defined for "example.com," but the record "host2.example.org" is included in the zone. The record "host2.example.org" is outside the zone's hierarchy, as it belongs to the "example.org" domain, not "example.com." This is a misconfiguration in the zone file.
