A. The RIP route
B. The static route
C. The IGRP route
D. All three will load balance.
Answer: B
Explanation:
To decide which route to use, IOS uses a concept called administrative Distance. Administrative distance is a number that denotes how believable an entire routing protocol is on a single router. The lower the number, the better, or more believable the routing protocol.
Route Type Administrative Distance
• Static 1
• IGRP 100
• RIP 120
2.What could be the rationale behind using passive-interface command when configuring a router?
A. Allows interfaces to share common IP addresses.
B. Allows an interface to remain up without the aid of keepalives.
C. Allows a router to send routing and not receive updates via that interface.
D. Allows a routing protocol to forward updates that is missing its IP address.
E. Allows a router to receive routing updates on an interface but not send updates via that interface.
Answer: E
Explanation:
The passive-interface command is used to control the advertisement of routing information. The command enables the suppression of routing updates over some interfaces while allowing updates to be exchanged normally over other interfaces.
With most routing protocols, the passive-interface command restricts outgoing advertisements only. However, when used with Enhanced Interior Gateway Routing Protocol (EIGRP), the effect is slightly different. This document demonstrates that use of the passive-interface command in EIGRP suppresses the exchange of hello packets between two routers, resulting in the loss of their neighbor relationship. This stops not only routing updates from being advertised, but it also suppresses incoming routing updates. This document also discusses the configuration required in order to allow the suppression of outgoing routing updates, while allowing incoming routing updates to be learnt normally from the neighbor.
3.What are the benefits of using a router to segment the network at a main office? (Select two options.)
A. Broadcasts are not forwarded across the router.
B. Broadcasts are eradicated.
C. Adding a router to the network decreases latency.
D. Filtering can occur based on Layer 3 information.
E. Routers are more efficient than switches.
Answer: A,D
Explanation
Routers do not forward broadcast messages and therefore breaks up a broadcast domain. In addition, routers can be used to filter network information.
4.Which of the following commands will you use to display the configuration register setting on a router?
A. show boot
B. show flash
C. show register
D. show version
E. show config
Answer: D
Explanation:
"show version" To display the configuration of the system hardware, the software version, the names and sources of configuration files, and the boot images, use the show version command in EXEC mode.
5.What are the characteristic of link state routing protocols? (Choose all that apply.)
A. The exchange of advertisement is triggered by a change in the network.
B. All routers exchange routing tables with each other iIn a multipoint network.
C. Packets are routed based upon the shortest path to the destination.
D. Paths are chosen depending on the cost efficiency factor.
E. Every router in an OSPF area is capable of representing the entire network topology.
F. Only the designated router in an OSPF area can represent the entire network topology.
Answer: A,C,E
Explanation:
Open Shortest Path First
• Each router discovers its neighbors on each interface. The list of neighbors is kept in a neighbor table.
• Each router uses a reliable protocol to exchange topology information with its neighbors.
• Each router places the learned topology information into its topology database.
• Each router runs the SPF algorithm against its own topology database.
• Each router runs the SPF algorithm against its own topology database to calculate the best routes to each subnet in the database.
• Each router places the best roué to each subnet into the IP routing table. The following list points out some of the key features of OSPF:
• Converges very quickly – from the point of recognizing a failure, it often can converge in less than 10 seconds.
• Supports VLSM.
• Uses short Hello messages on a short regular interval, with the absence of hello messages indicating that a neighbor is no longer reachable.
• Sends partial updates when link status changes, and floods full updates every 30 minutes. The flooding, however, does not happened all at once, so the overhead s minimal.
• Uses cost for the metric.
6.You are a network technician at RJP. A newly appointed trainee wants to know what the basics of distance vector and link state routing protocols are. What would your reply be? (Choose all that apply.)
A. Distance vector protocols send the entire routing table to directly connected neighbors.
B. Distance vector protocols are responsible for sending updates to all networks listed in the routing table.
C. Link state protocols are responsible for sending the entire routing table to the whole network.
D. Link state protocols send updates regarding their own links status to all other routers on the network.
Answer: A,D
Explanation:
Distance Vector Protocols:
Distance Vector Protocols advertise routing information by sending messages, called routing updates, out the interfaces on a router. These updates contain a series of entries, with each entry representing a subnet and a metric.
Link-State Protocols:
Sends partial updates when link status changes and floods full updates every 30 minutes. The flooding, however, does not happen all at once, so the overhead is minimal.
7.Which of the following statements is true regarding the split horizon rule?
A. Distance vector protocols need fall back routes that are responsible for momentary loops.
B. Networks can only remain fully operational provided all information is sent out all active interfaces.
C. Each AS must keep routing tables converged to avoid dead routes from being advertised.
D. Information about a route should not be sent back in the direction from which the original update came.
E. Only routers can split boundaries (horizons) between concentric networks.
Answer: D
Explanation:
Split horizon blocks information about routes from being advertised by a router out of any interface from which that information originated.
8.You are a network technician at RJP. You are working with a 2500 series Cisco router. You are performing the password recovery procedure. You have just typed the following command:
o/r 0x2142
Your newly appointed trainee is curious about why this command is used. What should you tell him?
A. It is used to restart the router.
B. It is used to bypass the configuration in NVRAM.
C. It is used to enter ROM Monitor mode.
D. It is used to view the lost password.
E. It is used to save the changes to the configuration.
Answer: B
Explanation:
The o/r 0x2142 command changes the value of config-register to 2142, so that the Router ignores the NVRAM contents when it boots.
9.You are a network technician at RJP. You have told a newly appointed trainee that the OSI model has 7 layers and that the Application layer is the highest layer. The trainee is curious as to which protocols operate at the application layer. What should you tell him? (Choose all that apply.)

13.What could you use to prevent rooting loops in the network when configuring the network using a distance vector routing protocol? (Choose all that apply.)
A. Spanning Tree Protocol
B. Shortest path first tree
C. Link-state advertisements (LSA)
D. Hold-down timers
E. Split horizon
F. VRP
Answer: D, E
Explanation:
• Split horizon – the routing protocol advertises routes out an interface only if they were not learned from updates entering that interface.
• Hold-down timer – After finding out that a router to a subnet has failed, a router waits a certain period of time before believing any other routing information about that subnet.
14.You are a network technician at RJP, Inc. You have completed the password recovery procedure on a Cisco router successfully and the router returned to normal operation. What is configuration register value at this point in time?
A. 0x2112
B. 0x2104
C. 0x2102
D. 0x2101
E. 0x2100
Answer: C
Explanation:
It is default factory setting. Router should attempt to load an IOS from flash memory and load startup configuration file. Flash memory also called NVRAM
15.Documenting the name of the IOS image file of each router in the network is part of updating network documentation. Which of the following commands can be used to obtain this information?
A. Router# show IOS
B. Router# show version
C. Router# show image
D. Router# show protocols
E. Router# show flash
Answer: B
"Show flash" displays all the image files in it. There could be more than one file. However, "show version" displays the one that is currently in use by the router.
16.Which of the following statements describes the rule of split horizon?
A. Only routers can split boundaries (horizons) between concentric networks.
B. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.
C. Networks can only remain fully converged if all information is sent out all active interfaces.
D. Information about a route should not be sent back in the direction from which the original update came.
E. Distance vector protocols need fall back routers that are responsible for momentary loops.
Answer: D
Explanation:
Split horizon includes two related concepts that affect what routes are included in a routing update: An update does not include the subnet of the interface out which the update is sent All routes with outgoing interface of interface x are not included in updates sent out that same interface x.
17.Which of the following features are PPP characteristics? (Choose all that apply.)
A. Encapsulates several different types of routing protocols.
B. Supports only IP.
C. Can be used over analog circuits.
D. Maps Layer addresses.
E. Corrects errors.
Answer: A, C, E
Explanation:
• PPP can be used on either type of line (dial or switched lines), because data-link protocols are designed for point-to-point environment.
• PPP uses one LCP per link and one Control Protocol for each Layer 3 protocol defined on the link. If a router is configured for IPX, Apple Talk, and IP on a PPP serial link, the router configured for PPP encapsulation automatically tries to bring I the appropriate control protocols for each layer 3 protocol.
• Error recovery can be performed by the data-link protocol or a higher-layer protocol, or it might not be performed at all. Supported but not enabled by default.
18.You are a network technician at RJP, Inc. You are troubleshooting a connectivity problem. You issue the ping command during a router console session. Your trainee wants to know what the ping command use to test connectivity between the two devices. What would your reply be?
A. ICMP echo request
B. Information interrupt request
C. Timestamp reply
D. Source quench
Answer: A
Explanation:
The ping command sends an ICMP echo request packet to the stated destination address. The TCP/IP software at the destination then replies to the ping echo request packet with a similar packet, called ICMP echo reply.
19.You are a network technician at RJP, Inc. You must assign static IP addresses to the servers in the RJP network. For network 192.168.20.24/29 the router is assigned the first usable host address while the sales server is given the last usable host address. Which of the following should be entered into the IP properties box for the sales server?
A. IP address: 192.168.20.14 Subnet Mask: 255.255.255.248 Default Gateway: 192.168.20.9
B. IP address: 192.168.20.254 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.20.1
C. IP address: 192.168.20.30 Subnet Mask 255.255.255.248 Default Gateway: 192.168.20.25
D. IP address: 192.168.20.30 Subnet Mask 255.255.255.240 Default Gateway: 192.168.20.17
E. IP address: 192.168.20.30 Subnet Mask 255.255.255.240 Default Gateway: 192.168.20.25
Answer: C
Explanation
A subnet mask uses 29 bits. This means that it uses
5 bits in the 4th octet. This equates to 255.255.255.248. This network has 3 bits for hosts. Using the 2^n - 2 formula (2^3 -2 in this case), we are left with 6 (2*2*2 - 2 = 6) host addresses. 192.168.20.24 is the network address. Therefore the next address (192.168.20.25) would be the first host address. This address must be assigned to the router, which serves as the gateway for the network. The last available host address would be 192.168.20.30 (192.168.20.24+6). This address is assigned to the server.

25.Characteristic such as Acknowledgements, sequencing, and flow control are typical of which OSI layer?
A. Layer 2
B. Layer 3
C. Layer 4
D. Layer 5
E. Layer 6
F. Layer 7
Answer: C
Explanation
The Transport layer (Layer 4) defines several functions, including the choice of protocols. The most important Layer 4 functions are error recovery and flow control. The transport layer may provide for retransmission, i.e., error recovery, and may use flow control to prevent unnecessary congestion by attempting to send data at a rate that the network can accommodate, or it might not, depending on the choice of protocols. Multiplexing of incoming data for different flows to applications on the same host is also performed. Reordering of the incoming data stream when packets arrive out of order is included. Examples include: TCP, UDP, and SPX.
