* Authentication will succeed and EIGRP updates can be exchanged.
Authentication will fail because the key chain names must match the router names.
What is a characteristic of FTP traffic flows?

low throughput with high response-time requirements



4
If a router is unable to find a suitable IOS to load into RAM, in what mode does the boot process end?
* setup mode
user mode
rommon mode
privileged mode



5
In a converged network, which two types of traffic would be categorized as real-time traffic? (Choose two.)
e-mail
file transfer
web browsing
* videoconferencing
* voice over IP
video on demand



6
A company uses the Frame Relay network to establish a VPN connection between headquarters and the branch office. The company wants to add a backup link in case the Frame Relay connection fails. The backup link will use the business DSL connection through another ISP. How should the router be configured to include the backup link?
Create a static route with the administrative distance of 1.
Create a floating static route.
Add a new route to the routing protocol configuration.
Create a second default route for the backup path.



7



Refer to the exhibit. What is the spanning-tree role of all the enabled interfaces of SW11?

A WIC-1T module needs to be installed in a Cisco 1841 router that currently has a WIC-2T module in slot 0. What should the network technician do first?
Install the hot-swappable option module.
* Turn off the power to the router before installing the new module.
Remove the WIC-2T module so that the new module can be installed in slot 0.
Shut down all Fast Ethernet ports on the router until the new WIC module installation is complete.
Configure the Cisco IOS software to support an internal trunk link between the two WIC modules.



9
During prototype testing, a LAN switch fails. As the switch re-initializes using the default parameters, a port that has a PC attached transitions to the forwarding state within one second. What protocol would support this feature?
STP
RIP
BGP
VTP
* RSTP



10
What are two accurate descriptors of a DLCI? (Choose two.)
* Frame Relay Layer 2 address
* one DLCI allowed per local loop
locally significant circuit endpoint
signaling standard between DTE and DCE
establishes the data transfer rate through a Frame Relay network



11
A user in a large office calls technical support to complain that a PC has suddenly lost connectivity to the network. The technician asks the caller to talk to nearby users to see if other machines are affected. The caller reports that several immediate neighbors in the same department have a similar problem and that they cannot ping each other. Those who are seated in other departments have connectivity. What should the technician check as the first step in troubleshooting the issue?
the power outlet to the PC that is used by the caller.
the trunks between switches in the wiring closet.
* the status of the departmental workgroup switch in the wiring closet.
the cable that connects the PC of the caller to the network jack.
the cable connection between a PC and a network outlet that is used by a neighbor.



12
A NetworkingCompany engineer is on a support call resolving technical problems for a client network. After the issue is resolved, the engineer also provides a training session for the network support staff. What role is the engineer filling on the networking company team?
* post-sales field engineer
pre-sales engineer
network designer
account manager



13



Refer to the exhibit. The network administrator has used the Cisco Feature Navigator to choose a Cisco IOS image to install on a router. Given the exhibited output of the show version command, which statement is true about the capacity of the router to use this Cisco IOS image?
There is enough DRAM and flash.
There is not enough DRAM and flash.
There is enough DRAM but not enough flash.
There is not enough DRAM but enough flash.



14



Refer to the exhibit. The named ACL "Managers" already exists on the router. What will happen when the network administrator issues the commands that are shown in the exhibit?
The commands overwrite the existing Managers ACL.
The commands are added at the end of the existing Managers ACL.
* The commands are added at the beginning of the existing Managers ACL.
The network administrator receives an error that states that the ACL already exists.



15



Refer to the exhibit. A company with four servers in its server farm has not enabled PVRST on the switches that connect to the server farm segment. What will happen within the network if a primary link goes down?
Access to the the servers will be lost.
Convergence time will be slow and possibly cause applications to time out.
Routing protocols will not send the triggered updates in the event of a failure of the root bridge.
Switches that connect the servers to the network will not be found by other switches in the network.

CCNA discovery 4 final exam v4.0 (December 2009)

1
Refer to the exhibit. A pre-sales system engineer receives a diagram of the
current network WAN connectivity from a customer. EIGRP is the routing protocol
used on the WAN. Based on the default operation of EIGRP, which statement is true
about the routing table on router R1?
There is a single route to the 192.168.16.0/28 LAN via the use of the T1
connection.
There is a single route to the 192.168.16.0/28 LAN via the use of the DSL
connection.
There is a single route to the 192.168.16.0/28 LAN via the use of the Metro
Ethernet connection.*****

EIGRP installs all three routes to the 192.168.16.0/28 LAN and load balances the
traffic.

and configured as shown in the output contained in the graphic. Which of the
following IP addresses should be assigned to this new host?
