   A multinational company has BIG-IP DNS in multiple regions. In one region, the DNS server is on a private network, but clients in another region query it via a public IP. The administrator has configured a translation address for the DNS server. However, clients in the same region as the DNS server are now receiving the public IP instead of the private IP, causing performance issues. What is the best solution?

   • ARemove the translation address and rely on the private IP for all clients.
   • BUse views to provide the private IP to local clients and the public IP to remote clients.
   • CChange the DNS server's listen address to the public IP.
   • DConfigure a second translation address for the same private IP.
