Sometimes SDN leverages various overlay networking technologies to create layer(s) of network abstraction.
What describes an overlay network?
- A . It transmits packets that traverse over network devices like switches and routers
- B . It encapsulates packets at source and destination, which incurs additional overhead
- C . Packet delivery and reliability occurs at Layer 3 and Layer 4
- D . It is responsible for the delivery of packets; NAT- or VRF-based segregation is required
Which two benefits can software defined networks provide to businesses? (Choose two.)
- A . provides additional redundancy
- B . decentralized management
- C . reduced latency
- D . enables innovation
- E . reduction of OpEx/CapEx
- F . meets high traffic demands
Cost is often one of the motivators for a business to migrate from a traditional network to a software-defined network.
Which design decision is directly influenced by CAPEX drivers?
- A . scalability
- B . stability
- C . complexity
- D . manageability

You are designing a new Ethernet-based metro-area network for an enterprise customer to connect 50 sites within the same city OSPF will be the routing protocol used. The customer is primarily concerned with IPv4 address conservation and convergence time.
Which two combined actions do you recommend? (Choose two)
- A . Use a multipoint Metro-E service for router connections
- B . Use a single address per router for all P2P links
- C . Use P2P links between routers in a hub-and-spoke design
- D . Configure address aggregation at each site router
- E . Determine which OSPF routers will be DR/BDR
A thorough examination of the curant network infrastructure has revealed that several devices have an unusual high CPU load A traffic analysis indicates that control plane protocols and management traffic are affected as the devices are busy processing inbound traffic The networking team is working on updating their design for the entre network to handle situations like this.
Which feature or technology can be added to help mitigate the problem?
- A . control plane policing
- B . deep uterface buffers
- C . TCAM carving
- D . modular QoS
What are two examples of components that are part of an SDN architecture? (Choose two.)
- A . software plane
- B . control plane
- C . application plane
- D . management plane
- E . network plane

Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two)
- A . will only work with single-tier headend architecture
- B . hub sites must connect to both DMVPN clouds
- C . recommended for high availability
- D . spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly
- E . requires all sites to have dual Internet connections
