   A company has a BIG-IP DNS that is used for both internal and external DNS resolution. They have configured translation addresses for external clients. However, internal clients are now receiving the public IPs instead of private IPs, causing them to traverse the firewall unnecessarily. What is the best way to fix this?

   • AChange the internal clients' DNS servers to a different BIG-IP DNS.
   • BRemove the translation addresses and use only private IPs.
   • CUse views to return private IPs to internal clients and public IPs to external clients.
   • DConfigure a firewall rule to allow internal clients to use public IPs.

   An administrator is configuring BIG-IP DNS for a data center with a mix of internal and external clients. They have a limited number of public IPs and want to minimize the number of translation addresses. What is the most efficient approach?

   • AUse a NAT pool to translate multiple private IPs to a single public IP.
   • BDisable translation addresses and use only private IPs.
   • CUse a single translation address for all servers.
   • DUse views to return private IPs to internal clients and public IPs to external clients, using translation addresses only for external clients.

   An organization is deploying BIG-IP DNS in a hybrid cloud environment. The on-premises data center has private IPs, and the cloud VPC has its own private IPs. Clients in the cloud need to access on-premises servers via a VPN. The DNS responses from the on-premises BIG-IP DNS contain private IPs that are not routable in the cloud VPC. What is the best solution?

   • AConfigure translation addresses on the on-premises BIG-IP DNS to map on-premises private IPs to cloud-routable IPs.
   • BUse a VPN to route the private IPs directly.
   • CSet up a DNS forwarder in the cloud to forward queries to the on-premises DNS.
   • DUse a cloud DNS service to resolve on-premises names.
