Cisco 300-420 Practice Test - Questions Answers, Page 21

An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place. Which route filtering solution must the engineer employ?

In a cisco SD-Access brownfield deployment scenario, which configuration deployment must be taken with Cisco DNA center?

Refer to the exhibit.

A network engineer must design a multicast solution based on:

* Many-to-many communications between the users and sources

* Support of up to 50 multicast sources

* Users that must register for steams

Which multicast solution must the engineer select?

A customer plans to adopt distributed QoS in their enterprise WAN. The policy must allow for individual packet marking according to the type of treatment required and for forwarding based on hop-by-hop treatment locally defined on each device. Which technology must the customer select?

Refer to Exhibit.

Refer to the exhibit. A customer experienced an unexpected network outage when the link between

R1 and R2 went down. An architect must design a solution to ensure network continuity in the event the link fails again. Which solution should the design include?

Refer to Exhibit.

Refer to the exhibit A customer wants to adopt a dynamic site-to-site VPN solution to secure communication for VoIP, video, and FTP traffic between the remote branches and the headquarters.

The customer also wants the branches to communicate directly, thereby reducing traffic at the headquarters location. The solution must consider that the branch routers are limited in available memory. Which VPN solution meets these requirements?

Refer to Exhibit.

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?

An engineer must design a routing solution for a company that is single-homed to an ISP. The company's goal is to run BGP between the CE and the PE devices. To support running BGP, the company obtained a public AS number and IP subnet from ARIN. Which solution must the engineer select?

Which function do reverse path forwarding mechanisms perform in a multicast deployment?
