1 Refer to the exhibit.

The network administrator enters these commands into the R1 router:

R1# copy running-config tftp Address or name of remote host [ ]?

When the router prompts for an address or remote host name, what IP address should the administrator enter at the prompt?

192.168.9.254 192.168.10.1 192.168.10.2 192.168.11.254 192.168.11.252

2 Which three statements characterize the transport layer protocols? (Choose three.)

TCP uses port numbers to provide reliable transportation of IP packets.

TCP and UDP port numbers are used by application layer protocols. TCP uses windowing and sequencing to provide reliable transfer of data. TCP is a connection-oriented protocol. UDP is a connectionless protocol. UDP uses windowing and acknowledgments for reliable transfer of data.

3 What is the purpose of ICMP messages?

to inform routers about network topology changes

to ensure the delivery of an IP packet

to monitor the process of a domain name to IP address resolution to provide feedback of IP packet transmissions

4 A technician uses the ping 127.0.0.1 command. What is the technician testing?

connectivity between a PC and the default gateway connectivity between two adjacent Cisco devices physical connectivity of a particular PC and the network the TCP/IP stack on a network host

connectivity between two PCs on the same network

5 What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?

It notifies the sending host that the frame cannot be delivered.

It initiates an ARP request.

It forwards the frame out of all ports except for the port at which the frame was received. It broadcasts the frame out of all ports on the switch.

6 What is a characteristic of the LLC sublayer?

It places information in the frame that allows multiple Layer 3 protocols to use the same network interface and media.

It provides delimitation of data according to the physical signaling requirements of the medium. It defines software processes that provide services to the physical layer.

It provides the logical addressing required that identifies the device.

7On which switch interface would an administrator configure an IP address so that the switch can be managed remotely?

VLAN 1

console 0

vty 0 FastEthernet0/1

8A network engineer is measuring the transfer of bits across the company backbone for a mission critical database application. The engineer notices that the network throughput appears lower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)

the reliability of the gigabit Ethernet infrastructure of the backbone

the amount of traffic that is currently crossing the network the type of traffic that is crossing the network

the sophistication of the encapsulation method applied to the data the bandwidth of the WAN connection to the Internet

the latency that is created by the number of network devices that the data is crossing

9When applied to a router, which command would help mitigate brute-force password attacks against the router?

service password-encryption

login block-for 60 attempts 5 within 60

banner motd $Max failed logins = 5$ exec-timeout 30

10

Which two statements correctly describe a router memory type and its contents? (Choose two.)

ROM is nonvolatile and contains basic diagnostic software.

CCNA5.NET CCNA5.NET - MIPDF.COM MIPDF.COM

FLASH is nonvolatile and contains a limited portion of the IOS. ROM is nonvolatile and stores the running IOS.

RAM is volatile and stores the IP routing table.

NVRAM is nonvolatile and stores other system files.

11

Which two components are necessary for a wireless client to be installed on a WLAN? (Choose two.)

custom adapter

wireless bridge

media

wireless NIC

crossover cable

wireless client software

13

A host is accessing a Web server on a remote network. Which three functions are performed by intermediary network devices during this conversation? (Choose three.)

applying security settings to control the flow of data notifying other devices when errors occur regenerating data signals

acting as a client or a server

serving as the source or destination of the messages providing a channel over which messages travel

16

Which address on a PC does not change, even if the PC is moved to a different network?

IP address

logical address

MAC address

default gateway address

17

What will happen if the default gateway address is incorrectly configured on a host?

A ping from the host to 127.0.0.1 would not be successful.

The host will have to use ARP to determine the correct address of the default gateway. The host cannot communicate with other hosts in the local network.

The host cannot communicate with hosts in other networks.

The switch will not forward packets initiated by the host.

18

A host PC has just booted and is attempting to lease an address through DHCP. Which two messages will the client typically broadcast on the network? (Choose two.)

15

DHCPREQUEST

DHCPOFFER

DHCPDISCOVER

DHCPNACK DHCPACK

19

Refer to the exhibit. An administrator wants to change the name of a brand new switch, using the hostname command as shown. What prompt will display after the command is issued?

Switch# My(config)#

My Switch(config)# Switch(config)# MySwitch(config)#

20

After making configuration changes, a network administrator issues a copy running-config startup-config command in a Cisco switch. What is the result of issuing this command?

The configuration changes will be removed and the original configuration will be restored. The new configuration will be stored in flash memory.

The current IOS file will be replaced with the newly configured file.

The new configuration will be
