Certified Ethical Hacker (CEH v10) — Question 62

During a recent security assessment, you discover the organization has one Domain Name Server (DNS) in a Demilitarized Zone (DMZ) and a second DNS server on the internal network.
What is this type of DNS configuration commonly called?

Answer options

• A. DynDNS
• B. DNS Scheme
• C. DNSSEC
• D. Split DNS

Correct answer: D

Explanation

The correct answer is 'Split DNS', which refers to the configuration where different DNS servers are used for internal and external queries. 'DynDNS' is a dynamic DNS service, 'DNS Scheme' is not a recognized term in this context, and 'DNSSEC' refers to security extensions for DNS, not the structure of the DNS deployment.
