action should the account manager take
Inform the customer that the project budget must be increased
Inform the customer that the project cannot be completed given the unreasonable budget constraints
Communicate any risks that are associated with the equipment substitution and obtain customer approval to
proceed
Because the customer is probably aware that the budget limitations will require lower cost less capable
equipment the account manager should do nothing
25
Refer to the exhibit What can the field engineer conclude about the EIGRP authentication between Router1 and
Router2
Authentication will fail because only one key is configured
Authentication will succeed and EIGRP updates can be exchanged
Authentication will fail because the key chain names do not match
Authentication will fail because the key chain names must match the router names

24 During a review of the proposed bill of materials an account manager of the network solution company realizes
that the systems engineer included a switch with lower cost and reduced capabilities for the access layer than
was originally specified by the network designer When questioned the systems engineer responds that the
switches specified by the designer cannot be purchased within the budget limitations of the customer Which
action should the account manager take
Inform the customer that the project budget must be increased
Inform the customer that the project cannot be completed given the unreasonable budget constraints
Communicate any risks that are associated with the equipment substitution and obtain customer approval to
proceed
Because the customer is probably aware that the budget limitations will require lower cost less capable
equipment the account manager should do nothing
25
Refer to the exhibit What can the field engineer conclude about the EIGRP authentication between Router1 and
Router2

partial mesh topology
It adds scalability to the corporate network
It provides fully redundant links to connecting modules
It lowers the impact and risk of DoS attacks from the Internet
It increases the manageability of the network devices in the core layer
23 What are two disadvantages to using simulation software such as Packet Tracer to validate a network design
(Choose two)
unrealistic performance
little control over network operation
inability to create large or complex networks
inability to simulate all required network conditions
lack of flexibility to support different devices and connectivity options
24 During a review of the proposed bill of materials an account manager of the network solution company realizes
that the systems engineer included a switch with lower cost and reduced capabilities for the access layer than
was originally specified by the network designer When questioned the systems engineer responds that the
switches specified by the designer cannot be purchased within the budget limitations of the customer Which
action should the account manager take
Inform the customer that the project budget must be increased
Inform the customer that the project cannot be completed given the unreasonable budget constraints
Communicate any risks that are associated with the equipment substitution and obtain customer approval to
proceed
Because the customer is probably aware that the budget limitations will require lower cost less capable
equipment the account manager should do nothing
25
Refer to the exhibit What can the field engineer conclude about the EIGRP authentication between Router1 and
Router2
Authentication will fail because only one key is configured
Authentication will succeed and EIGRP updates can be exchanged
Authentication will fail because the key chain names do not match
Authentication will fail because the key chain names must match the router names
26 A network designer must select a routing protocol for the network of a customer The currently installed network
contains both Cisco and non-Cisco routers and there is no budget to replace them The designer plans on

22 What is one advantage of a full mesh topology at the core layer of the enterprise network compared with a
partial mesh topology
It adds scalability to the corporate network
It provides fully redundant links to connecting modules
It lowers the impact and risk of DoS attacks from the Internet
It increases the manageability of the network devices in the core layer
23 What are two disadvantages to using simulation software such as Packet Tracer to validate a network design
(Choose two)
unrealistic performance
little control over network operation
inability to create large or complex networks
inability to simulate all required network conditions
lack of flexibility to support different devices and connectivity options
24 During a review of the proposed bill of materials an account manager of the network solution company realizes
that the systems engineer included a switch with lower cost and reduced capabilities for the access layer than
was originally specified by the network designer When questioned the systems engineer responds that the
switches specified by the designer cannot be purchased within the budget limitations of the customer Which
action should the account manager take
Inform the customer that the project budget must be increased
Inform the customer that the project cannot be completed given the unreasonable budget constraints
Communicate any risks that are associated with the equipment substitution and obtain customer approval to
proceed
Because the customer is probably aware that the budget limitations will require lower cost less capable
equipment the account manager should do nothing
25
Refer to the exhibit What can the field engineer conclude about the EIGRP authentication between Router1 and
Router2
Authentication will fail because only one key is configured
Authentication will succeed and EIGRP updates can be exchanged
Authentication will fail because the key chain names do not match
Authentication will fail because the key chain names must match the router names
26 A network designer must select a routing protocol for the network of a customer The currently installed network
contains both Cisco and non-Cisco routers and there is no budget to replace them The designer plans on
implementing both VLSM and route summarization in the new network design Which two protocols can
provide the necessary functionality for this LAN (Choose two)
RTP
RSTP
RIPv1
RIPv2
EIGRP
OSPF
27 A company offers online ordering of its products The web service is provided by a primary web server that
synchronizes with a backup server A network designer recommends adding a load balancing unit and installing
additional web servers so that the online ordering traffic can be equally distributed among four web servers
What network design risk is addressed with this recommendation
limited bandwidth
possible bottleneck
single point of failure
large failure domains
28
Refer to the exhibit A network administrator configures two routers to test the WAN connection The serial
connection requires PPP encapsulation and authentication with CHAP However the connection cannot be
established According to the partial output of the show running-config command what is the cause of the
problem
The password should be all lowercase
The password should contain fewer than 8 characters
The usernames must be the same as the sending router hostnames
The usernames must be the same as the destination router hostnames
29 In order for the IT staff of a company to understand the basic operation of VPNs which two features or
technologies must the network designer identify as training needs (Choose two)
IPv6 tunneling
QoS operation
tunneling protocols
VLAN configuration
encryption algorithms
30 What is a function of software queuing
filters traffic on the basis of administrator defined rules
stores received traffic and sends packets based on the order that the packets are received
sends packets on the basis of priorities that are manually set
transmits packets in a priority sequence that is based on source port

46 What makes the Cisco EasyVPN application a useful tool for VPN implementation
It provides encryption algorithms unavailable in other systems
It ensures that remote workers actually use the VPN for connectivity
It simplifies the configuration tasks for the device that is used as the VPN server
It allows a greater variety of network devices to be used for VPN connections
47
Refer to the exhibit A customer has a problem with connectivity in the network Based on the IP addressing
scheme what is causing the problem
The WAN link that connects R1 to R3 has an incorrect mask
The WAN links need IP addresses from a different major network
The WAN link that connects R1 to R2 overlaps with the R3 LAN
The IP addressing in R1 LAN is incorrect because subnet zero cannot be used with VLSM
48 Which technical requirement is satisfied when providing QoS for delay sensitive applications
availability
manageability
scalability
security
49 Which statement best describes the VPN feature called split tunneling
It creates separate pathways for different VLANs
It creates two tunnels one for user traffic and one for management traffic such as CDP and SNMP
It allows user traffic that is destined for the corporate network to travel across the VPN tunnel while traffic
destined for the Internet travels through the local LAN of the VPN client
It allows separate tunnels so that high priority traffic such as voice and video uses the higher bandwidth
tunnel while all other user traffic travels on the lower bandwidth tunnel
50 As part of network monitoring a network administrator receives an alert that the CPU usage of the core router
reaches 90 several times a day Which protocol is in use to monitor the network performance
DNS
SNMP
SMTP
DHCP
TFTP
51 The main office of a NetworkingCompany customer currently connects to three branch offices via three separate
point-to-point T1 circuits The customer network uses RIPv2 as the routing protocol within both the LAN and
the WAN The account manager proposes a change to a Frame Relay network because the costs are lower A
single local loop connection can be installed at the main office with three separate PVCs to connect the branch
offices How can the main office edge router be configured to enable the customer to continue to use RIP as the
WAN routing protocol
Enable Inverse ARP on the serial interface in order to learn the routes to the IP addresses of the remote
routers
To prevent the Frame Relay network from causing a routing loop disable split horizon on the serial
interface
Create three separate point-to-point subinterfaces on the serial interface and assign a different subnet IP
address to each one
Configure the serial interface with a single interface DLCI number and create frame-relay map statements
for each remote site address
52 Which command can be used to load a new Cisco IOS image on a router
copy startup-config tftp
copy tftp startup-config
copy running-config tftp
copy tftp flash
copy flash tftp
copy flash startup-config
