Cisco 300-420 Practice Test - Questions Answers, Page 29

Refer to the exhibit.

Refer to the exhibit. An engineer proposed this solution for a company that requires a loop-free. Layer 2 network design. The network will run 802.1W, and all links will be 1 Gbps. If all interfaces are up as point- to-point adjacencies, what are the expected port end states based on the design?

What is the purpose of the fabric control plane in a Cisco SD-Access architecture?

A company requires a private WAN design that allows remote sites to connect to HQ. The design must ensure that:

traffic is always encrypted

forwarding overhead is reduced

management of security Is centralized

multicast traffic is supported

Which technology must the company select?

An architect must design a topology for a WAN network that satisfies these requirements:

Devices must be able to make informed decisions.

Suboptimal paths are allowed only In case of a failure.

Backup paths must always be available.

Which topology must the architect select?

A customer is undergoing a WAN re-architecture and wants to design QoS policies for remote sites that have low bandwidth. What must be considered to have CBWFQ configured in the parent and child policies in an end-to-end QoS design?

A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DMVPN back to the hub using two 100 Mbps internet connections. Both links must be used due to spikes in traffic, and routing must take traffic utilization of the links into account. Also, the branch routers have limited memory and CPU resources. Which routing protocol and design solution must the company choose?

Refer to the exhibit.

Refer to the exhibit. An architect must design a resilient gateway solution based on these requirements:

VLAN 10 and VLAN 11 support voice and video applications.

Link and node failures must have minimal impact on traffic.

Provide protection against false hello packets.

Support IPv6.

Which solution must the architect choose?

In a Cisco SD-Access fabric, switch node Is equivalent to an access layer switch In a traditional three-tier campus network design?

An architect must design a QoS model for a business-critical application that Is delay-sensitive and requires high bandwidth. The company's head office hosts the application, and DMVPN tunnels protected with IPsec provide connectivity between the head office and branches. Which solution must the architect choose?
