   A company is migrating a large-scale web application to an SDN-based cloud. The application experiences unpredictable traffic spikes. The SDN environment uses a centralized controller. The network team is concerned about the controller's ability to handle the increased number of flow requests during spikes. Which strategy is most effective to mitigate this risk?

   • AImplement proactive flow provisioning by pre-populating flow entries in the switches based on expected traffic patterns.
   • BIncrease the controller's hardware resources to handle more flow requests.
   • CDeploy multiple controllers in a cluster to distribute the load.
   • DDisable the controller's flow request handling and rely on static flows.

   A network operations team is integrating a new SDN environment with their existing IT service management (ITSM) platform. The ITSM platform uses a change management process that requires network changes to be approved and logged. The SDN controller provides a REST API. The team wants to automate network changes but still enforce the change management process. Which approach is most effective?

   • ABuild a middleware that intercepts API calls to the SDN controller, logs them, and enforces approval workflows before forwarding to the controller.
   • BDisable the API and require all changes to be made through the ITSM platform manually.
   • CUse the SDN controller's built-in logging and hope that it satisfies the ITSM requirements.
   • DAllow direct API access to the SDN controller and rely on post-change auditing.

   A company is migrating to an SDN environment that uses a centralized controller. The security team requires that all traffic between VMs be inspected by a firewall. The SDN controller supports service chaining. What is the most efficient way to enforce this security policy?

   • AInstall firewall agents on each VM to inspect traffic locally.
   • BConfigure the SDN controller to steer all inter-VM traffic through a service chain that includes the firewall.
   • CUse network ACLs on the virtual switches to block traffic that does not go through the firewall.
   • DPlace the firewall on the default gateway and route all traffic through it.
