Place the following steps in the correct order to verify client DNS name resolution against a specific authoritative DNS server.

Reliable troubleshooting starts by confirming that the client queries the intended DNS server. The administrator then runs the appropriate `nslookup` command, checks the response against the forward or reverse zone contents, and determines whether the requested record exists. If the resolver address is wrong, a response may not reflect the lab’s DNS configuration. If a record was never created, a negative result can be expected rather than evidence of a DNS service failure. **Key takeaway:** Verify the query path and expected record before diagnosing a failure.\n\n**Glossary:** **Resolver**: The DNS server receiving a client’s query. **Zone**: A managed collection of DNS records. **Negative result**: A response indicating the requested record was not found.
