A network architect is designing a software-defined network for a university campus. The campus has multiple buildings, each with its own distribution switch. The architect wants to centralize the control plane but is concerned about the impact of a WAN outage between buildings. Which design consideration is most important to maintain network availability?

Configure the switches to operate in standalone mode if the controller is unreachable.

Use the data plane to handle control plane functions during a WAN outage.

Use a single centralized controller in one building and rely on the WAN for all control traffic.

Place a controller in each building to maintain local control plane functionality.

A network engineer is troubleshooting a VXLAN overlay issue in a data center. The overlay is working, but some tenants cannot communicate with each other. The engineer suspects that the underlay is not delivering VXLAN packets correctly. Which check should the engineer perform first?

Verify that the overlay control plane is learning MAC addresses.

Verify that the VXLAN VNI is correctly mapped to the tenant VLAN.

Verify that the northbound API is functioning correctly.

Verify that the underlay routing protocol is advertising the VXLAN tunnel endpoints' IP addresses.

A company is using an SDN controller with a REST northbound API. The network team wants to automate the creation of new virtual networks. However, the application team is concerned about security and wants to ensure that only authorized applications can make changes. Which mechanism should be implemented?

Use API keys and role-based access control (RBAC) on the controller.

Use SNMP community strings for authentication.

Use the same credentials as the network administrator for all applications.

Use a VPN to connect to the controller and assume that is sufficient.

A cloud provider is integrating its orchestration platform with an SDN controller. The platform needs to provision isolated networks for customers and enforce QoS policies. The orchestration team wants to use a RESTful API. Which approach is most appropriate?

Use the southbound API directly to configure each switch individually.

Use SNMP to set QoS policies on each device.

Use the controller's northbound REST API to send intent-based requests for network creation and policy enforcement.

Use CLI commands on the controller to configure networks.
