640-822 Exam Questions and Answers (2016 Updated):

Qustion No. 1

Which two characteristics apply to Layer 2 switches? (Choose two.) 

A. increases the number of collision domains 

B. decreases the number of collision domains 

C. implements VLAN 

D. decreases the number of broadcast domains 

E. uses the IP address to make decisions for forwarding data packets 

Answer: AC 

Qustion No. 2




Router#config terminal 

Router(config)#hostname Apopka 

2) Enable-secret password (cisco10): 

Apopka(config)#enable secret cisco10 

3) Set the console password to RouterPass: 

Apopka(config)#line console 0 

Apopka(config-line)#password RouterPass 



4) Set the Telnet password to scan90: 

Apopka(config)#line vty 0 4 

Apopka(config-line)#password scan90 



5) Configure Ethernet interface (on the right) of router Apopka: 

The subnet mask of the Ethernet network is 27. From this subnet mask, we can find out the increment by converting it into binary form, that is /27 = 1111 1111.1111 1111.1111 1111.1110 0000. Pay more attention to the last bit 1 because it tells us the increment, using the formula: 

Increment = 2place of the last bit 1 (starts counting from 0,from right to left), in this case increment = 25 = 32. Therefore: 

Increment: 32 

Network address: 

Broadcast address: (because is the second subnetwork, so the previous IP – – is the broadcast address of the first subnet). 

-> The second assignable host address of this subnetwork is 

Assign the second assignable host address to Fa0/0 interface of Apopka router: 

Apopka(config)#interface Fa0/0 

Apopka(config-if)#ip address 

Apopka(config-if)#no shutdown 


6) Configure Serial interface (on the left) of router Apopka: 

Using the same method to find out the increment of the Serial network: 

Serial network 

Increment: 16 (/28 = 1111 1111.1111 1111.1111 1111.1111 0000) 

Network address: (because 8 * 16 = 128 so is also the network address of this subnet) 

Broadcast address: 

-> The last assignable host address in this subnet is 

Assign the last assignable host address to S0/0/0 interface of Apopka router: 

Apopka(config)#interface S0/0/0 (or use interface S0/0 if not successful) 

Apopka(config-if)#ip address 

Apopka(config-if)#no shutdown 


7) Configure RIP v2 routing protocol: 

Apopka(config)#router rip 

Apopka(config-router)#version 2 



Apopka(config-router)#end Save the configuration: 

Apopka#copy running-config startup-config 

Finally, you should use the ping command to verify all are working properly! 


Qustion No. 3

Which transport layer protocol is best suited for the transport of VoIP data? 






Answer: B 

Qustion No. 4

Which three statements are true about the operation of a full-duplex Ethernet network? (Choose three.) 

A. There are no collisions in full-duplex mode. 

B. A dedicated switch port is required for each full-duplex node. 

C. Ethernet hub ports are preconfigured for full-duplex mode. 

D. In a full-duplex environment, the host network card must check for the availability of the network media before transmitting. 

E. The host network card and the switch port must be capable of operating in full-duplex mode. 

Answer: ABE 

Qustion No. 5

You do not have access to a network server and need to back up a Cisco IOS image. Which utility can you use to achieve this goal? 

A. tftp 

B. ftp 

C. http 

D. xmodem 

E. rcp 

Answer: D
