  B. Layer 3
  C. Layer 4
  D. Layer 5
  A. Layer 2

  ---

  Point-to-Point Protocol (PPP) is a data link protocol commonly used in establishing a direct connection between two networking nodes. It can provide connection authentication, transmission (using ECP, RFC 1968), and compression. encryption

• Question 144:

  At which layer of the OSI model is RSTP used to prevent loops?

  A. physical
  B. data link
  C. network
  D. transport
  B. data link

  ---

  RSTP and STP operate on switches and are based on the exchange of Bridge Protocol Data Units (BPDUs) between switches. One of the most important fields in BPDUs is the Bridge Priority in which the MAC address is used to elect the Root Bridge , RSTP operates at Layer 2. http://www.cisco.com/en/US/tech/tk389/tk621/technologies_white_paper09186a0080094cfa.shtml

• Question 145:

  Refer to the exhibit.

  

  Hosts in network 192.168.2.0 are unable to reach hosts in network 192.168.3.0. Based on the output from RouterA, what are two possible reasons for the failure? (Choose two.)

  A. The cable that is connected to S0/0 on RouterA is faulty.
  B. Interface S0/0 on RouterB is administratively down.
  C. Interface S0/0 on RouterA is configured with an incorrect subnet mask.
  D. The IP address that is configured on S0/0 of RouterB is not in the correct subnet.
  E. Interface S0/0 on RouterA is not receiving a clock signal from the CSU/DSU.
  F. The encapsulation that is configured on S0/0 of RouterB does not match the encapsulation that is configured on S0/0 of RouterA.
  E. Interface S0/0 on RouterA is not receiving a clock signal from the CSU/DSU.
  F. The encapsulation that is configured on S0/0 of RouterB does not match the encapsulation that is configured on S0/0 of RouterA.

• Question 146:

  A new switch is being added to the River Campus LAN. You will work to complete this process by first configuring the building_2 switch with an IP address and default gateway. For the switch host address, you should use the last available IP address on the management subnet. In addition, the switch needs to be configured to be in the same VTP domain as the building_1 switch and also needs to be configured as a VTP client. Assume that the IP configuration and VTP configuration on building_1 are complete and correct. The configuration of the router is not accessible for this exercise. You must accomplish the following tasks: Determine and configure the IP host address of the new switch. Determine and configure the default gateway of the new switch. Determine and configure the correct VTP domain name for the new switch. Configure the new switch as a VTP client.

  

  Correct Answer. Here are the Steps for this Lab Solution:
  Here are the Steps for this Lab Solution:

  ---

  The question states we can't access the router so we can only get required information from switch building_1. Click on the PC connected with switch building_1 (through a console line) to access switch building_1s CLI. On this switch use the show running-config command: building_1#show running-config Next use the show vtp status command to learn about the vtp domain on this switch building_1#show vtp status (Notice: the IP address, IP default-gateway and VTP domain name might be different!!!) You should write down these 3 parameters carefully. Configuring the new switch

  +

  Determine and configure the IP host address of the new switch The question requires "for the switch host address, you should use the last available IP address on the management subnet". The building_1 switch's IP address, which is 192.168.22.50 255.255.255.224, belongs to the management subnet. Increment: 32 (because 224 = 1110 0000) Network address: 192.168.22.32 Broadcast address: 192.168.22.63 ->The last available IP address on the management subnet is 192.168.22.62 and it hasn't been used (notice that the IP address of Fa0/1 interface of the router is also the default gateway address 192.168.22.35). Also notice that the management IP address of a switch should be configured in Vlan1 interface. After it is configured, we can connect to it via telnet or SSH to manage it. Switch2#configure terminal Switch2(config)#interface Vlan1 Switch2(config-if)#ip address 192.168.22.62 255.255.255.224 Switch2(config-if)#no shutdown (not really necessary since VLAN interfaces are not physical and are not shut down but, no harm in doing so and is good practice for physical ports)

  +

  Determine and configure the default gateway of the new switch The default gateway of this new switch is same as that of building_1 switch, which is 192.168.22.35 Switch2(config-if)#exit Switch2(config)#ip default-gateway 192.168.22.35

  +

  Determine and configure the correct VTP domain name for the new switch The VTP domain name shown on building_1 switch is Cisco so we have to use it in the new switch (notice: the VTP domain name will be different in the exam and it is case sensitive so be careful) Switch2(config)#vtp domain Cisco

  +

  Configure the new switch as a VTP client Switch2(config)#vtp mode client We should check the new configuration with the "show running-config" and "show vtp status"; also try pinging from the new switch to the the default gateway to make sure it works well. Finally save the configuration: Switch2(config)#exit Switch2#copy running-config startup-config

• Question 147:

  Refer to the exhibit.

  

  If the router R1 returns the given output and has not had its router ID set manually, what address will EIGRP use as its router ID?

  A. 192.168.1.2
  B. 172.16.4.1
  C. 192.168.10.2
  D. 1.1.1.1
  D. 1.1.1.1

• Question 148:

  Refer to the exhibit.

  

  RTA is configured with a basic configuration. The link between the two routers is operational and no routing protocols are configured on either router. The line shown in the exhibit is then added to router RTA. Should interface Fa0/0 on router RTB shut down, what effect will the shutdown have on router RTA?

  A. A route to 172.16.14.0/24 will remain in the RTA routing table.
  B. A packet to host 172.16.14.225 will be dropped by router RTA.
  C. Router RTA will send an ICMP packet to attempt to verify the route.
  D. Because router RTB will send a poison reverse packet to router RTA, RTA will remove the route.
  A. A route to 172.16.14.0/24 will remain in the RTA routing table.
