  C. They indicate received frames that did not pass the FCS match.
  D. They are frames that exceed 1518 bytes.
  E. They occur when CRC errors and interference occur on the cable.
  A. They may indicate a duplex mismatch.
  B. By definition, they occur after the 512th bit of the frame has been transmitted.

• Question 202:

  You have been asked to come up with a subnet mask that will allow all three web servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement?

  A. 192.168.252.0 255.255.255.252
  B. 192.168.252.8 255.255.255.248
  C. 192.168.252.8 255.255.255.252
  D. 192.168.252.16 255.255.255.240
  E. 192.168.252.16 255.255.255.252
  B. 192.168.252.8 255.255.255.248

  ---

  A subnet mask of 255.255.255.248 will allow for up to 6 hosts to reside in this network. A subnet mask of 255.255.255.252 will allow for only 2 usable IP addresses, since we cannot use the network or broadcast address.

• Question 203:

  After you configure the Loopback0 interface, which command can you enter to verify the status of the interface and determine whether fast switching is enabled?

  A. Router#show ip interface loopback 0
  B. Router#show run
  C. Router#show interface loopback 0
  D. Router#show ip interface brief
  A. Router#show ip interface loopback 0

• Question 204:

  How does using the service password-encryption command on a router provide additional security?

  A. by encrypting all passwords passing through the router
  B. by encrypting passwords in the plain text configuration file
  C. by requiring entry of encrypted passwords for access to the device
  D. by configuring an MD5 encrypted key to be used by routing protocols to validate routing exchanges
  E. by automatically suggesting encrypted passwords for use in configuring the router
  B. by encrypting passwords in the plain text configuration file

  ---

  By using this command, all the (current and future) passwords are encrypted. This command is primarily useful for keeping unauthorized individuals from viewing your password in your configuration file

• Question 205:

  DRAG DROP

  Drag the cable type on the left to the purpose for which it is best suited on the right. (Not all options are used.)

  Select and Place:

  

  

  ---

  To remember which type of cable you should use, follow these tips:

  -To connect two serial interfaces of 2 routers we use serial cable

  – To specify when we use crossover cable or straight-through cable, we should remember: Group 1: Router, Host, Server Group 2: Hub, Switch One device in group 1 + One device in group 2: use straight-through cableTwo devices in the same group: use crossover cable For example: we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server… and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host…)

• Question 206:

  SIMULATION

  CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP.

  CCNA.com has recently added the ENG router. Currently, the ENG router does not have connectivity to the ISP router. All over interconnectivity and Internet access for the existing locations of the company are working properly.

  The task is to identify the fault(s) and correct the router configuration(s) to provide full connectivity between the routers.

  Access to the router CLI can be gained by clicking on the appropriate host.

  All passwords on all routers are cisco.

  IP addresses are listed in the chart below.

  MGT

  Fa0/0 – 192.168.77.33 S1/0 – 198.0.18.6 S0/0 – 192.168.27.9 S0/1 – 192.168.50.21

  ENG

  Fa0/0 – 192.168.77.34 Fa1/0 – 192.168.12.17 Fa0/1 – 192.168.12.1

  Parts1

  Fa0/0 – 192.168.12.33 Fa0/1 – 192.168.12.49 S0/0 – 192.168.27.10

• Question 207:

  Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.) Router(config)# router ospf 1

  A. All OSPF routers in an area must have the same process ID.
  B. Only one process number can be used on the same router.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.
  E. Hello packets are sent to each neighbor to determine the processor identifier.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.

  ---

  Multiple OSPF processes can be configured on a router using multiple process ID's. The valid process ID's are shown below:

  Edge-B(config)#router ospf ?

  <1-65535> Process ID

• Question 208:

  Refer to the exhibit.

  

  A network technician is asked to design a small network with redundancy. The exhibit represents this design, with all hosts configured in the same VLAN. What conclusions can be made about this design?

  A. This design will function as intended.
  B. Spanning-tree will need to be used.
  C. The router will not accept the addressing scheme.
  D. The connection between switches should be a trunk.
  E. The router interfaces must be encapsulated with the 802.1Q protocol.
  C. The router will not accept the addressing scheme.

  ---

  Each interface on a router must be in a different network. If two interfaces are in the same network, the router will not accept it and show error when the administrator assigns it.

• Question 209:

  Scenario:

  Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the

  main office and the routers located in the remote branch offices.

  

  

  

  An OSPF neighbor adjacency is not formed between R3 in the main office and R4 in the Branch1 office. What is causing the problem?

  A. There is an area ID mismatch.
  B. There is a Layer 2 issue; an encapsulation mismatch on serial links.
  C. There is an OSPF hello and dead interval mismatch.
  D. The R3 router ID is configured on R4.
  A. There is an area ID mismatch.

  ---

  A show running-config command on R3 and R4 shows that R4 is incorrectly configured for area 2:

  

• Question 210:

  What are the three things that the Netflow uses to consider the traffic to be in a same flow? (Choose three)

  A. IP address
  B. Interface name
  C. Port numbers
  D. L3 protocol type
  E. MAC address
  A. IP address
  C. Port numbers
  D. L3 protocol type

  What is an IP Flow?

  Each packet that is forwarded within a router or switch is examined for a set of IP packet attributes. These attributes are the IP packet identity or fingerprint of the packet and determine if the packet is unique or similar to other packets.

  Traditionally, an IP Flow is based on a set of 5 and up to 7 IP packet attributes.

  IP Packet attributes used by NetFlow:

  +

  IP source address

  +

  IP destination address

  +

  Source port

  +

  Destination port

  +

  Layer 3 protocol type

  +

  Class of Service

  +

  Router or switch interface
