Question 1

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 scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?

A : M-SSM

B : M-SM

C : DP

D : BIDIR-PIM

Answer: B

Question 2

An engineer is designing a Layer 3 campus network running EIGRP between the core, aggregation, and access layers. The access layer switches will be connected to the aggregation layer using Layer 3 copper connections. The engineer wants to improve the convergence time for access layer switch failures. Which technique must the design include?

A : abling BFD for EIGRP on the access layer uplinks

B : ducing the EIGRP Hello / Hold timer values

C : EIGRP summarization from core to aggregation layer

D : GRP summarization from access to aggregation layer

Answer: A

Question 3

Refer to the exhibit. An engineer is designing a BGP solution for a client that peers with ISP1 for full Internet connectivity and with ISP2 for direct exchange of routes for several third parties. Which action, when implemented on the edge routers, enables the client network to reach the Internet through ISP1?

A : n an eBGP session within different VRFs for each ISP

B : Advertise a default route for downstream routers within the client network

C : ply the AS-path prepend feature for ISP2

D : ply route filtering such that the client advertises only routes originated from its own AS

Answer: B

Question 4

A network engineer must design an MSDP multicast solution to provide RP resilience in a network with two separate domains. Also, multicast sources and receivers must register with the local RP. Which solution must the engineer choose?

A : nfigure the RP has value to 0, and traffic will route to the closest RP

B : nfigure the RP loopback interface with the same IP address/32, and traffic will route to the closest RP

C : nfigure the RP group ranges to split the multicast traffic, and traffic will route to the longest match

D : nfigure the RP priority with the same value, and traffic will route to the closest RP

Answer: B

Question 5

A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?

A : ilize BFD and tune the multiplier to 50

B : wer the BGP hello interva

C : Decrease the BGP keepalive timer

D : ilize BFD and keep the default BGP timers
