In a GSLB deployment with the same host name for internal and external users, which DNS feature enables returning different destinations based on the client perspective?

In a GSLB deployment with the same host name for internal and external users, which DNS feature enables returning different destinations based on the client perspective?

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

Answer: (C)

This question centers on delivering DNS responses that vary by who is asking, so the right mechanism is DNS View. With DNS View, you define separate response sets for different client perspectives (for example, internal versus external users based on source IP or network location). Each view can return a different set of A or CNAME records for the same host name, so internal clients resolve to internal destinations while external clients resolve to external destinations, all under the same name. This split-horizon DNS behavior is exactly what lets a single host name point to different back-end pools depending on the client’s location. The other options don’t provide this client-aware differentiation: a DNS record is just a static mapping, a DNS proxy forwards queries without perspective-based customization, and the concept of a preferred location doesn’t enable per-client responses.
