   Which statement best describes a general constraint that SDN architectures impose on network components such as F5 devices?

   • ANetwork components must rely on distributed control plane decisions made locally by each device.
   • BNetwork components are free to implement proprietary protocols without controller involvement.
   • CNetwork components must be physically connected to the controller via a dedicated management network.
   • DNetwork components must accept forwarding decisions and policies from a centralized controller.

   An enterprise is deploying F5 BIG-IP virtual editions in a VXLAN overlay to connect workloads across two data centers. The network team is concerned about the impact of VXLAN encapsulation on the BIG-IP's performance. Which action should be taken to minimize the performance impact?

   • ADisable TCP segmentation offload on the BIG-IP VE.
   • BIncrease the MTU on the underlay network to accommodate the VXLAN overhead.
   • CPlace the BIG-IP in the underlay network to avoid VXLAN processing.
   • DEnable VXLAN hardware offload on the BIG-IP VE.

   Which limitation is commonly associated with SDN controller integration for F5 devices?

   • AF5 devices cannot be used in SDN environments.
   • BF5 devices must be manually configured for every policy change.
   • CThe controller may not support all F5 features or configurations.
   • DSDN controllers can only manage virtual F5 appliances.

   How does VXLAN encapsulation affect F5 performance?

   • AIt reduces latency because VXLAN uses a shorter header.
   • BIt adds encapsulation overhead, which can reduce throughput and increase latency.
   • CIt has no impact on performance because encapsulation is done in hardware.
   • DIt increases throughput because VXLAN adds no overhead.

   What is a primary effect of OpenFlow-based centralized control on F5 components?

   • AF5 devices are limited to using only static routes.
   • BF5 devices must rely on the controller for forwarding decisions.
   • CF5 devices must maintain their own independent routing tables.
   • DF5 devices can ignore controller instructions for local traffic.
