Cisco 300-420 Practice Test - Questions Answers, Page 10

An architect is creating a migration strategy for a large organization in which the choice made by the application between IPv6 and IPv4 is based on the DNS request. Which migration strategy does the architect choose?

Refer to the exhibit.

Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain.

Which action should the engineer take?

An engineer must propose a solution for a campus network that includes the capability to create multiple Layer 3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding. The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?

Refer to the exhibit.

Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:

The routers will not learn any prefix with a subnet mask greater than /24.

The routers will determine the routes to include in the routing table based on the length of the mask alone.

The routers will make this selection regardless of the service provider configuration.

Which solution should the engineer include in the design?

An engineer is designing an EIGRP network for a small branch site where there is only one Layer 3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?

A network engineer is redesigning a company's QoS solution. The company is currently using IP Precedence, but the engineer plans to move to DiffServ. It is important that the new solution provide backward compatibility with the current solution. Which technology should the design include?

A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals: reduce the impact of topology changes reduce the time spent on network administration reduce manual configuration errors Which two solutions should the architect include in the new design? (Choose two.)

How is sub-second failure of a transport link detected in a Cisco SD-WAN network?
