Cisco 300-420 Practice Test - Questions Answers, Page 13

An engineer must design a large Layer 2 domain that contains hundreds of switches and VLANs. The engineer's primary goals are to:

•Efficiently utilize the bandwidth of all links

•Avoid Layer 2 loops

•Cause minimal impact on switch CPU and memory

Which technology should the engineer include in the design?

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

An organization plans to deploy multicast across two different autonomous systems. Their solution must allow RPs to:

•discover active sources outside their domain

•use the underlying routing information for connectivity with other RPs

•announce sources joining the group

Which solution supports these requirements?

Refer to the exhibit.

Refer to the exhibit. The full EIGRP routing table is advertised throughout the network. Currently, users experience data loss when any one link in the network fails. An architect optimizes the network to reduce the impact when a link fails.

Which solution should the architect include in the design?

The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?

Refer to the exhibit.

Refer to the exhibit. An architect must design a solution to connect the two ASs. To optimize bandwidth, the design will implement load sharing between router R6 and router R4. Which solution should the design include?

Refer to the exhibit.

Refer to the exhibit. AS65533 and AS65530 are announcing a partial Internet routing table as well as their IP subnets. An architect must create a design that ensures AS64512 become a transit AS. Which filtering solution must the architect choose?

Refer to the exhibit.

Refer to the exhibit. Where must an architect plan for route summarization for the topology?

An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?
