In a GSLB deployment using the same hostname for internal and external traffic, which DNS feature allows serving different responses based on client location?

• A. DNS Proxy
• B. DNS Record
• C. DNS View
• D. DNS Preferred Location

Answer: (C)

Split-horizon DNS, implemented as DNS View, lets a DNS server return different answers based on who is asking (typically by the client’s IP or network location). In a GSLB setup that uses the same hostname for internal and external traffic, DNS View enables internal clients to receive internal IPs while external clients get external IPs. This behavior matches the need to route traffic differently depending on client location without changing the hostname. DNS Proxy merely forwards queries without altering responses by location, DNS Records provide a single static mapping, and DNS Preferred Location influences which site is favored rather than tailoring the actual DNS response to the requester.
