   A company runs a web application behind a BIG-IP that performs SNAT for outbound traffic. The BIG-IP DNS auto-discovery feature is configured to discover the application servers. The DNS team notices that the discovered records contain the SNAT address instead of the original server IP. What is the most likely cause and what should be done to correct it?

   • AThe auto-discovery probe is being translated by SNAT; configure the probe to use the original client IP or disable SNAT for the discovery traffic.
   • BAuto-discovery is incompatible with SNAT; disable SNAT on the virtual server.
   • CThe discovered records are correct; SNAT is the address that should be used for DNS responses.
   • DAuto-discovery only works with NAT, not SNAT; switch to NAT.

   What is the primary purpose of auto-discovery in a BIG-IP DNS deployment?

   • ATo synchronize DNS records with external DNS providers
   • BTo automatically create DNS records for all hosts in the internal network
   • CTo dynamically add and remove BIG-IP DNS objects based on changes in the network
   • DTo replace manual configuration of all DNS zones

   How does auto-discovery interact with address translation settings such as NAT?

   • AAuto-discovery ignores NAT and uses the original destination IP
   • BAuto-discovery only works with SNAT, not NAT
   • CAuto-discovery uses the translated address when NAT is enabled
   • DAuto-discovery disables NAT on discovered objects

   What is the purpose of associating a discovered object with a specific route domain?

   • ATo enable translation for the discovered object
   • BTo apply different DNS policies per route domain
   • CTo ensure DNS resolution uses the correct network segment
   • DTo limit auto-discovery to certain route domains

   A company has a multi-tier application where the web servers are in route domain 1 and the application servers are in route domain 2. They use auto-discovery to create DNS records for both tiers. The web servers are behind a NAT that translates their private addresses to public addresses. The application servers are not translated. What is the correct approach for configuring auto-discovery for these two tiers?

   • ADisable translation for the web servers and use the same configuration for both tiers.
   • BCreate separate auto-discovery configurations for each tier, specifying the correct route domain and translation settings for each.
   • CUse the same auto-discovery configuration for both tiers, as translation and route domain do not affect discovery.
   • DConfigure auto-discovery only for the web servers, as they are the only ones that need DNS records.
