The development of a connected ecosystem of devices reflects manufacturers ' heightened focus on internal needs and issues as they work to increase product resiliency and improve customer experience In which two ways can network visibility contribute to resilient software defined networking? (Choose two.)
Company ABC wants to minimize the risk of users plugging unauthorized switches and hubs into the network. Which two features can be used on the LAN access ports to support this design requirement? (Choose two.)
Refer to the exhibit.

Company XYZ must design a DMVPN tunnel between the three sites. Chicago is going to act as the NHS, and the company wants DMVPN to detect peer endpoint failures. Which technology should be used in the design?
With virtualization being applied in many parts of the network, every physical link is likely to carry one or more virtual links, but what is a drawback in cases like this?

An organization has two branches connected over the Internet circuit using IPsec tunnels established on their edge routers belonging to different vendors Recently these branches were the victims of a DoS attack resulting in failure to establish the tunnels They are now looking for a better tunneling solution allowing full interoperability between vendors and allowing a standardized set of authentication methods Furthermore the solution must support detection of the peer’s state as well as having support for next-gen encryption algorithms. Which protocol meets these requirements and is known to be resistant to DoS attacks?
Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop-free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?
When a traditional network is transformed to a hierarchical network, the state information in the control plane is reduced so that changes in one area of the network do not result in changes in the routing table on devices half-way around the globe What is a potential trade off in these cases?
Company XYZ needs advice in redesigning their legacy Layer 2 infrastructure. Which technology should be included in the design to minimize or avoid convergence delays due to STP or FHRP and provide a loop-free topology?
Refer to the exhibit.

Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is overutilized. Which design solution solves this issue?
A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location. The networks are joined to enable host migration at Layer 2. Which activity should be completed each time a legacy network is migrated?
