   A company has a BIG-IP GTM that is authoritative for its domain. They notice that the GTM receives queries from a variety of public recursive resolvers, but they want to ensure that queries from a specific internal network are always seen as coming from a single IP address. They have an internal DNS forwarder. What is the best way to achieve this?

   • AConfigure the internal clients to use a public recursive resolver
   • BConfigure the internal forwarder to forward all queries to the GTM
   • CConfigure the internal clients to query the GTM directly
   • DConfigure the GTM to accept queries only from the internal forwarder's IP

   • BThe client's IP address
   • CThe public recursive resolver's IP address
   • DThe root server's IP address

   A diagram shows a client querying a recursive resolver. The recursive resolver has a cached answer but the TTL has expired, so it must query the GTM. What source IP does the GTM see?

   • AThe client's IP address
   • BThe root server's IP address
   • CThe GTM's IP address
   • DThe recursive resolver's IP address

   In a DNS hierarchy diagram, a user's device is configured to use a public recursive resolver (8.8.8.8). The recursive resolver queries the GTM for a record. What source IP does the GTM see?

   • AThe user's device IP address
   • BThe root server's IP address
   • CThe GTM's IP address
   • D8.8.8.8
