Question

julie configures two dns servers, one internal and one external, with authoritative zones for the corpnet.xyz domain. one dns server directs external clients to an external server. the other dns server directs internal clients to an internal server. which of the following dns countermeasures is she implementing?

• split dns
• information sharing policy
• dns propagation
• proxy server

i want to review this question later. (optional)

Explanation:

Split DNS is a configuration that uses separate DNS servers (internal and external) for the same domain, directing internal and external clients to different respective servers, which matches Julie's setup. The other options do not fit: an information sharing policy is a procedural rule, DNS propagation is the spread of DNS records, and a proxy server acts as an intermediary for requests, not this dual DNS configuration.

Answer:

Split DNS
