300-420 Designing Cisco Enterprise Networks (ENSLD) Questions and Answers

Which two functions are provided by the Cisco SD-WAN orchestration plane? (Choose two.)

An engineer must design an in-band management solution for a customer with branch sites. The solution must allow remote management of the branch sites using management protocols over an MPLS WAN. Queueing is implemented at the remote sites using these classes:

How must the solution prioritize the management traffic over the WAN?

Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A’s network, both companies use overlapping IP address ranges. Which action conserves IP address space and provides access to the server?

A network solution is being designed for a company that connects to multiple Internet service providers. Which Cisco proprietary BGP path attribute will influence outbound traffic flow?

Refer to the exhibit. An engineer must design an address translation solution to provide Internet connectivity for the corporate network. The design Is restricted to the 172.16.168.0/22 subnet. Which solution must the engineer choose?

In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

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.)

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 network engineer must segregate three interconnected campus networks using IS-ISrouting. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically. Which two actions does the engineer take to accomplish this segregation? (Choose two.)

An enterprise customer has these requirements:

• end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.
• flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.
• support for full-mesh connectivity at Layer 2.

Which WAN connectivity option meets these requirements?

What is one function of the vSmart controller in an SD-WAN deployment?

Which component is part of the Cisco SD-Access overlay architecture?

An engineer must design a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?

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 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?

Refer to the exhibit. An engineer is planning an IPv4 to IPv6 migration solution for a customer. The routers in the network can support IPv4 and IPv6, except for the DWDM routers. The DWDM routers provide a Layer 2 link in which the routers peer directly with each other across a DWDM circuit. The circuit also provides connectivity between the mail servers. Which IPv6 migration technique must the engineer deploy?

Refer to the exhibit. A network engineer must design a BGP solution based on:

• The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
• The route reflector must have full redundancy and avoid a single point of failure.
• R2 to R1 link utilization is 90%. and the remaining links are less than 50% utilized.

Which two solutions must the design Include?(Choose two.)

Refer to the exhibit.

The failover time of ISP-2 is significantly shorter than ISP-1 when an interface on the ISP router toward the campus network fails. Which solution minimizes the downtime to the sub-second?

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

same VPN?

A company plans to transition to IPv6. They will link their IPv4 addresses to the lowest significant bits of the new Ipv6 addresses. A network administrator with an employee id: 4264:42:116 is preparing a mapping schema for the new IPv6 addresses. Which address does the 172.16.10.0/24 network translate to?

Refer to the exhibit. The distribution switches serve as the layer 3 boundary. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?

A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

Refer to the exhibit. A network engineer is designing an OSPF solution to connect a company's remote to a newly provisioned MPLS VPN backbone. Some of the branches have a direct dark fiber connection between each other. The engineer wants to ensure that the dark fibers are used only when the MPLS core is unavailable. Which solution must the engineer choose?

Refer to the exhibit. An engineer Is designing a redistribution solution for a customer. The customer recently acquired another company and decided to integrate the new network running RlPv1 with the company's existing network. Which redistribution technique must the engineer select to ensure the multipoint two-way redistribution does not cause routing loops?

Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?

What is the purpose of a Cisco SD-Access underlay network?

Which feature must be incorporated into the campus LAN design to enable Wake on LAN?

Drag and drop the characteristics from the left onto the YANG models they describe on the right. Not all options are used.

Which function does the Cisco SD-Access intermediate node perform?

An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?
