Which of the following provide inter-switch VLAN communication?



ISL is a Cisco-proprietary frame-tagging method. IEEE 802.1Q is the nonproprietary version of frame tagging.

You type the following command into the router and receive the following output:

Router#show serial 0/0
% Invalid input detected at '^' marker.
Why was this error message displayed?


You can view the interface statistics from user mode, but the command is show interface serial 0/0.

3. A receiving host has failed to receive all of the segments that it should acknowledge. What can the host do to improve the reliability of this communication session?


A receiving host can control the transmitter by using flow control (TCP uses Windowing by default). By decreasing the window size, the receiving host can slow down the transmitting host so the receiving host does not overflow its buffers.

Which statement is true regarding classless routing protocols?

The use of discontiguous networks is not allowed.
The use of variable length subnet masks is permitted.
RIPv1 is a classless routing protocol.
IGRP supports classless routing within the same autonomous system.
RIPv2 supports classless routing.


Classful routing means that all hosts in the internetwork use the same mask. Classless routing means that you can use Variable Length Subnet Masks (VLSMs) and can also support discontiguous networking.

5. Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?


When a routing update is received by a router, the router first checks the administrative distance (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD, then the router will choose the one route with the lowest metrics, or in RIP's case, hop count.

6. When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?


Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your nonproduction test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.

What multicast addresses does RIPng use?


RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.

Which of the following is true regarding VLANs?


Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link.

9. How many simultaneous Telnet sessions does a Cisco router support by default?


Cisco routers, if they do not have the Enterprise edition of the IOS, will default to 5 simultaneous Telnet sessions.

Which layer 1 devices can be used to enlarge the area covered by a single LAN segment?

RJ45 transceiver


Not that you really want to enlarge a single collision domain, but a hub (multiport repeater) will provide this for you.

11. You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be?


This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.

12. Suppose that you have a customer who has a central HQ and six branch offices. They anticipate adding six more branches in the near future. They wish to implement a WAN technology that will allow the branches to economically connect to HQ and you have no free ports on the HQ router. Which of the following would you recommend?


The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.

13. Which command would you place on interface connected to the Internet?


As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command ip nat inside. On the outside interface, you will use the command ip nat outside.

If you want to have more than one Telnet session open at the same time, what keystroke combination would you use?


To keep open one or more Telnet sessions, use the Ctrl+Shift+6 and then X keystroke combination.

Pat Address Translation is also termed what?


Another term for port address translation is NAT Overload because that is the command used to enable port address translation.

16. Which of the following is true when describing a link-local address?


Link-local addresses are meant for throwing together a temporary LAN for meetings or a small LAN that is not going to be routed but needs to share and access files and services locally.

The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols, needs authentication of users connecting to the network, and since some calls will be long distance, needs callback support. Which of the following protocols is the best choice for these remote services?


PPP is your only option, as HDLC and Frame Relay do not support these types of business requirements. PPP provides dynamic addressing, authentication using PAP or CHAP, and callback services.

IGRP uses which of the following as default parameters for finding the best path to a remote network?

Hop count
Cumulative interface delay
Path bandwidth value


IGRP uses bandwidth and delay of the line, by default, to determine the best path to a remote network. Delay of the line can sometimes be called the cumulative interface delay.

19. You need to configure a router for a Frame Relay connection to a non-Cisco router. Which of the following commands will prepare the WAN interface of the router for this connection?


If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the other side, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay network.

20. Which command will show you all the translations active on your router?


The command show ip nat translations will show you the translation table containing all the active NAT entries.

   What does RIPv2 use to prevent routing loops?
Split horizon
Classless masking
Holddown timers


RIPv2 uses the same timers and loop-avoidance schemes as RIPv1. Split horizon is used to stop an update from being sent out the same interface it was received on. Holddown timers allow time for a network to become stable in the case of a flapping link.

22. What layer in the TCP/IP stack is equivalent to the Transport layer of the OSI model?


The four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.

What is the maximum data rate for the 802.11a standard?


The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps.

24. Which command will show you whether a DTE or a DCE cable is plugged into serial 0?


The show controllers serial 0 command will show you whether either a DTE or DCE cable is connected to the interface. If it is a DCE connection, you need to add clocking with the clock rate command.

25. In which of the following technologies is the term HFC used?


In a modern network, hybrid fibre-coaxial (HFC) is a telecommunications industry term for a network that incorporates both optical fiber and coaxial cable to create a broadband network.

26. Which protocol reduces administrative overhead in a switched network by allowing the configuration of a new VLAN to be distributed to all the switches in a domain?


Virtual Trunk Protocol (VTP) is used to pass a VLAN database to any or all switches in the switched network. The three VTP modes are server, client, and transparent.

Which switching technology reduces the size of a broadcast domain?


Virtual LANs break up broadcast domains in layer 2 switched internetworks.

28. Which command will allow you to see real-time translations on your router?


The command debug ip nat will show you in real time the translations occurring on your router.

29. To back up an IOS, what command will you use?


The command copy flash tftp will prompt you to back up an existing IOS in flash to a TFTP host.

30. You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?


You need 5 subnets, each with at least 16 hosts. The mask provides 16 subnets with 14 hosts-this will not work. The mask provides 8 subnets, each with 30 hosts. This is the best answer.
