Cisco 640-802 Online Practice Questions and Exam Preparation

Cisco 640-802 Online Questions & Answers

• Question 311:

  Refer to the exhibit.

  

  The company uses EIGRP as the routing protocol. What path will packets take from a host on the 192.168.10.192/26 network to a host on the LAN attached to router R1?

  A. The path of the packets will be R3 to R2 to R1.
  B. The path of the packets will be R3 to R1 to R2.
  C. The path of the packets will be both R3 to R2 to R1 AND R3 to R1.
  D. The path of the packets will be R3 to R1.
  D. The path of the packets will be R3 to R1.

  ---

  Host on the LAN attached to router R1 belongs to 192.168.10.64/26 subnet. From the output of the routing table of R3 we learn this network can be reach via 192.168.10.9, which is an IP address in 192.168.10.8/30 network (the network between R1 and R3) -> packets destined for 192.168.10.64 will be routed from R3 -> R1 -> LAN on R1.

• Question 312:

  Which command encrypts all plaintext passwords?

  A. Router# service password-encryption
  B. Router(config)# password-encryption
  C. Router(config)# service password-encryption
  D. Router# password-encryption
  C. Router(config)# service password-encryption

  ---

  Command

  The "service password-encryption" command allows you to encrypt all passwords on your router so they cannot be easily guessed from your running-config. This command uses a very weak encryption because the router has to be very

  quickly decode the passwords for its operation.

  It is meant to prevent someone from looking over your shoulder and seeing the password, that is all. This is configured in global configuration mode.

• Question 313:

  Refer to the exhibit.

  

  The Bigtime router is unable to authenticate to the Littletime router. What is the cause of the problem?

  A. The usernames are incorrectly configured on the two routers.
  B. The passwords do not match on the two routers.
  C. CHAP authentication cannot be used on a serial interface.
  D. The routers cannot be connected from interface S0/0 to interface S0/0.
  E. With CHAP authentication, one router must authenticate to another router. The routers cannot be configured to authenticate to each other.
  B. The passwords do not match on the two routers.

  ---

  With CHAP authentication, the configured passwords must be identical on each router. Here, it is configured as little123 on one side and big123 on the other.

• Question 314:

  An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below.

  

  Click the console connected to RouterC and issue the appropriate commands to answer the questions.

  

  

  What would be the effect of issuing the command ip access-group 115 in on the s0/0/1 interface?

  A. No host could connect to RouterC through s0/0/1.
  B. Telnet and ping would work but routing updates would fail.
  C. FTP, FTP-DATA, echo, and www would work but telnet would fail.
  D. Only traffic from the 10.4.4.0 network would pass through the interface.
  A. No host could connect to RouterC through s0/0/1.

  ---

  First let's see what was configured on interface S0/0/1:

  

• Question 315:

  DRAG DROP

  Drag the Cisco default administrative distance to the appropriate routing protocol or route. (Not all options are used.

  Select and Place:

  

  

• Question 316:

  Which technology allows a large number of private IP addresses to be represented by a smaller number of public IP addresses?

  A. NAT
  B. NTP
  C. RFC 1631
  D. RFC 1918
  A. NAT

• Question 317:

  Refer to the exhibit.

  

  Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2?

  A. This switch has more than one interface connected to the root network segment in VLAN 2.
  B. This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.
  C. This switch interface has a higher path cost to the root bridge than another in the topology.
  D. This switch has a lower bridge ID for VLAN 2 than the elected designated switch.
  C. This switch interface has a higher path cost to the root bridge than another in the topology.

  ---

  Since the port is in the blocked status, we must assume that there is a shorter path to the root bridge elsewhere.

• Question 318:

  DRAG DROP

  Refer to the exhibit. PC_1 is sending packets to the FTP server. Consider the packets as they leave RouterA interface Fa0/0 towards RouterB. Drag the correct frame and packet address to their place in the table.

  Select and Place:

  

  

• Question 319:

  Refer to the exhibit:

  

  What will Router1 do when it receives the data frame shown? (Choose three.)

  A. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.
  B. Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.
  C. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.
  D. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.
  E. Router1 will forward the data packet out interface FastEthernet0/1.
  F. Router1 will forward the data packet out interface FastEthernet0/2.
  A. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.
  C. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.
  F. Router1 will forward the data packet out interface FastEthernet0/2.

  ---

  Remember, the source and destination MAC changes as each router hop along with the TTL being decremented but the source and destination IP address remain the same from source to destination.

• Question 320:

  DRAG DROP

  Match the terms on the left with the appropriate OSI layer on the right. (Not all options are used.)
