The network administrator of a branch office network has decided to deploy Unicast RPF at the accesslayer.
He insists that the design must guarantee that all the packets arriving on the router interfaces areassigned to
the same interface subnet.
Which mode of Unicast RPF would you recommend as the lead network designer?
A. uRPF strict mode
B. uRPF loose mode
C. uRPF VRF mode
D. RPF feasible mode

In a network design using carrier Ethernet, which three mechanisms can be used to improve Layer 2 down
detection and thereby reduce routing convergence time? (Choose three.)
A. BFD
B. Ethernet port debounce timers
C. link-state tracking
D. object tracking
E. fast IGP hello

You are designing a solution to eliminate the risk of high CPU utilization on a core network composed of CRS-1 devices. Which option would eliminate the risk of high CPU utilization across the network?
A. Use Local Packet Transport Services (LPTS) to manage hardware SNMP flow rate.
B. Use the in-band control plane policy feature to reduce the SNMP flow rate.
C. Use the control plane policy feature and reduce SNMP flow rate.
D. Use control-plane management-plane in-band and reduce the SNMP flow rate.
E. Use the control-plane management-plane out-of-band feature to reduce the SNMP flow rate.

What are two benefits of using BFD for failure detection in the design of a network? (Choose two.)
A. BFD can provide failure detection in less than one second.
B. BFD can be used as a generic and consistent failure detection mechanism for EIGRP, IS-IS, and OSPF.
C. BFD eliminates router protocol hello notification.
D. BFD can be used for all types of network interfaces.
E. BFD is independent of the network protocol.

Your company experienced a number of network incidents that had a significant impact on business
operations. Because a root cause cannot be identified, your CTO asks you to help the network management
team implement the FCAPS framework. On which two areas would you provide guidance to the network
management team? (Choose two.)
A. change management
B. accounting management
C. service level management
D. fault management

A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has
failed. Which two of these actions would reduce that delay? (Choose two.)
A. Enable lower data link layer recovery systems to have an opportunity to restore the interface.
B. Increase the notification of interface flaps.
C. Reduce the time for the network to reconverge.
D. Increase network stability.

A designer is working with a large bank to redesign their network. The designer wants to minimize complaints
regarding slow application response times across the WAN. It is suspected that currently traffic is not being
classified and marked correctly somewhere in the network. Which tool should the designer recommend to
validate quality of service mappings and use?
66

A. SNMP
B. IPFIX
C. IP SLA
D. protocol analyzer
E. NBAR

Your company requires two diverse multihop External Border Gateway Protocol peerings to a partner network.
Which two methods would you use to improve lost peer detection? (Choose two.)
A. Use Bidirectional Forwarding Detection for the peers.
B. Use Selective Address Tracking and match the peers.
C. Use subsecond keepalives for the peers.
D. Use subsecond hold timers for the peers.
E. Use Fast Peering Session Deactivation for the peers.
F. Use subsecond minimum route advertisement Interval timers for the peers.

You are designing a traffic monitoring and analysis system for a customer. Which traffic monitoring technique
would you recommend to place the least amount of burden on the network infrastructure?
A. SPAN monitor ports
B. NetFlow
C. IP NBAR
D. passive taps

AS100 and AS200 each have two peering points in different parts of their network. AS100 would like to use
one of the links and keep the other link as backup. What should be changed for the design inside AS100 for
prefixes received from AS200?
A. MED
B. weight
C. AS-PATH
D. local preference
