400-007 practice questions, page 4 of 14, with answer review and explanations.
Question 16
Refer to the diagram. Which solution must be used to send traffic from the foreign wireless LAN controller to the anchor wireless LAN controller?
Send packets without encapsulation to the anchor controller over the routed network.
Encapsulate packets into an EoIP tunnel and send them to the anchor controller.
Send packets from the foreign controller to the anchor controller via Layer 3 MPLS VPN or VRF-Lite.
Send packets from the foreign controller to the anchor controller via IPinIP or IPsec tunnel.
Question 17
The Company XYZ network is experiencing attacks against their router. Which type of Control Plane Protection must be used on the router to protect all control plane IP traffic that is destined directly for one of the router interfaces?
Control Plane Protection transit subinterface
Control Plane Protection host subinterface
Control Plane Protection CEF-exception subinterface
Control Plane Protection main interface
Question 18
An architect designs a multi-controller network architecture with these requirements: * Achieve fast failover to control traffic when controllers fail. * Yield a short distance and high resiliency in the connection between the switches and the controller. * Reduce connectivity loss and enable smart recovery to improve the SDN survivability. * Improve connectivity by adding path diversity and capacity awareness for controllers. Which control plane component of the multi-controller must be built to meet the requirements?
control node reliability
control path reliability
controller state consistency
controller clustering
Question 19
Which two control plane policer designs must be considered to achieve high availability? (Choose two.)
Control plane policers are really needed only on externally facing devices.
Control plane policers can cause the network management systems to create false alarms.
Control plane policers require that adequate protocols overhead are factored in to allow protocol convergence.
Control plane policers must be processed before a forwarding decision is made.
Control plane policers are enforced in hardware to protect the software path, but they are hardware platform-dependent in terms of classification ability.
Question 20
A small organization of 20 employees is looking to deliver a network design service for modernizing customer networks to support advanced solutions. * Project scope and weekly progress should be visualized by the management. * Always consider feedback and make changes accordingly during the project. * Should consider flexibility to change scope at the point of time. Which project methodology meets the requirements and have the least impact on the outcome?
