   A company uses an SDN controller to dynamically provision application delivery services. They want to integrate F5 BIG-IP so that when a new application is deployed, the controller automatically creates a virtual server and pool. Which integration method is most appropriate?

   • AUse SNMP traps to notify the controller of configuration changes.
   • BManually configure the BIG-IP each time a new application is deployed.
   • CUse the BIG-IP's iControl REST API to allow the SDN controller to create and manage virtual servers.
   • DDeploy the BIG-IP as an OpenFlow switch to receive flow rules from the controller.

   • AUse the BIG-IP's CLI to apply changes.
   • BUse SNMP to monitor and adjust configuration.
   • CManually export and import configuration files.
   • DUse the iControl REST API to push and pull configuration changes.

   In a VMware NSX environment, an administrator plans to insert an F5 BIG-IP virtual edition (VE) as a service in a service chain. Which NSX capability is the primary mechanism that allows the BIG-IP VE to be attached to a service chain and receive redirected traffic?

   • AA distributed logical router (DLR) with a service insertion feature
   • BA VXLAN tunnel endpoint (VTEP) configured on the BIG-IP VE
   • CAn NSX Edge services gateway (ESG) with a load balancer configured
   • DA service insertion framework that attaches the BIG-IP VE to a logical switch or router

   What is a common constraint SDN-based security policies place on F5 enforcement?

   • AF5 devices must enforce security policies defined by the SDN controller.
   • BF5 devices must define their own security policies independently.
   • CF5 devices must use only ACLs for enforcement.
   • DF5 devices cannot enforce security policies in SDN environments.

   What is a scalability consideration for F5 devices in SDN environments?

   • AF5 devices must be scaled horizontally only.
   • BF5 devices must handle increased flow table sizes and controller communication.
   • CF5 devices must be scaled vertically only.
   • DF5 devices cannot scale in SDN environments.
