Pass the Cisco CCNP Enterprise 300-420 Questions and answers with CertsForce

Which feature is used to optimize WAN bandwidth of IGMP network traffic among WAN Edge routers in the

same VPN?

An engineer must use YANG with an XML representation to configure a Cisco IOS XE switch with these specifications:

IP address 10.10.10.10/27 configured on the interface GigabitEthernet2/1/0

connectivity from a directly connected host 10.10.10.1/27

Which YANG data model set must the engineer choose?

A)

B)

C)

D)

An engineer is designing an enterprise campus network. The LAN infrastructure consists of switches from multiple vendors, and Spanning Tree must be used as a Layer 2 loop prevention mechanism. All configured

VLANs must be grouped in two SIP instances. Which standards-based Spanning Tree technology supports this design solution?

An engineer uses Postman and YANG to configure a router with:

OSPF process ID 400

network 192.168.128.128/25 enabled for Area 0

Which get-config reply verifies that the model set was designed correctly?

A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services. The customer plans to migrate IPv4 services to the IPv6 topology, then decommission the IPv4 topology. Which topology supports these requirements?

An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?

A customer requires QoS to support multimedia conferencing over MPLS. The network architect chooses to use per-hop behavior. Which solution must the architect use to classify and mark traffic traveling between branch sites?

A customer requests a VPN solution to connect multiple sites with the company headquarters. All the sites use the same IP subnet. The engineer plans to use VPLS. Which solutions must the engineer include in the design?

A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:

» The company uses multicast to deliver training to the stores.

» The company uses dynamic routing protocols and has implemented QoS.

» To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.

Which solution should be included in this design?

Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?
