Dell EMC Specialist – Systems Administrator, ECS — Question 2

How should an administrator manually validate the DNS readiness of a customer network?

Answer options

• A. Run a traceroute to the DNS server
• B. Generate a Network PEQ
• C. Ping the default gateway of the management VLAN
• D. Run nslookup on server FQDN and IP

Correct answer: A

Explanation

Running a traceroute to the DNS server helps in determining the connectivity and path to the DNS server, which is crucial for validating DNS readiness. The other options, such as generating a Network PEQ or pinging the default gateway, do not specifically test DNS resolution, and while nslookup can check DNS functionality, it is not a direct connectivity test like a traceroute.
