Question 1

Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal

the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding

state?

Options :

A :

Binary indexed explicit routing

B : Binary intermediate enhanced routing

C : Bit indexed explicit replication

D : Bi-directional implicit replication

Answer: C

Question 2

A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50MSEC). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?

Options :

A : TE backup tunnel

B : Next-hop (NHop) tunnel

C : FRR Backup tunnel

D : next-next-hop (NNHop) tunnel

Answer: D

Question 3

A network engineer confirms that STP is enabled on all switches in the network. An edge switch is not sending or receiving configuration BPDUs, although it appears that everything is functioning correctly in the network. Which design explanation is true?

Options :

A : Bridge Assurance is enabled on the port

B : Storm control broadcast is enabled on the port

C : BPDU Guard is enabled on the port

D : REP is enabled on the port

Answer: D

Question 4

A customer asks you to perform a high level review of their upcoming WAN refresh for remote sites The review is specially focused on their retail store operations consisting of 500+ locations connected via mutlipoint IPsec VPN solution. Which routing protocol would be valid but would also be the most restrictive for the expansion of this deployment model?

Options :

A : EIGRP

B :

IS-IS

C : OSPF

D : BGP

Answer: B

Question 5

A BGP route reflector in the network is taking longer than expected to coverage during large network changes. Troubleshooting shows that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune the device performance?

Options :

A : Increase the size of the hold queue.

B : Increase the size of the large buffers.

C : Decrease the size of the small buffers.

D : Increase the keepalive timers for each BGP neighbor.
