Question 1

An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this are

a. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?

Answer : C

Question 2

A company is planning to open two new branches and allocate the 2a01:c30:16:7009::3800/118 IPv6 network for the region. Each branch should have the capacity to accommodate maximum of 200 hosts. Which two networks should the company use? (Choose two.)

Answer : A, D

Question 3

An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from sources in another AS. Which feature must the design include?

Answer : C

Question 4

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?

Answer : A

Question 5

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

Answer : D

Question 6

An engineer is designing an EIGRP network for a small branch site where there is only one Layer 3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN. Which action should the engineer take?

Answer : B

Question 7

An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:

The routers will not learn any prefix with a subnet mask greater than /24.

The routers will determine the routes to include in the routing table based on the length of the mask alone.

The routers will make this selection regardless of the service provider configuration.

Which solution should the engineer include in the design?

Answer : D
