Arrange the steps in the correct order to configure and verify DNS records for a new web service that requires both forward and reverse lookups.
Answer
Create the reverse lookup zone to support pointer records., Create the target host (A) record with an associated PTR record., Create the CNAME record pointing the alias to the target host., Query the DNS server to verify resolution of the alias and the PTR record.
Explanation
The exercise first creates the host record for the zone apex, then creates the `webserver` host record. Both host-record steps include the option to create an associated PTR record. After those mappings exist, the lab creates the `www` CNAME pointing to the webserver’s fully qualified name. The final step is to inspect the forward and reverse zones and verify what was created. **Key takeaway:** Host records establish address mappings; the alias is then added and the resulting records are inspected.\n\n**Glossary:** **PTR**: Reverse DNS record mapping an address to a name. **CNAME**: Alias record. **Forward zone**: Zone used for name-based DNS data.
