  Router has pointed default router to 192.168.4.1 and this subnet is connected via serial 2 interface. Router does not have router for the 192.0.2.156. so it will use the default gateway 192.168.4.1. A default route identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

  How To Configure Frame Relay Subinterfaces http://www.orbit-computer-solutions.com/How-To-Configure-Frame-Relay-Subinterfaces.php

  Step to configure Frame Relay subinterfaces on a physical interface:

  1.

  Remove any network layer address (IP) assigned to the physical interface. If the physical interface has an address, frames are not received by the local subinterfaces.

  2.

  Configure Frame Relay encapsulation on the physical interface using the encapsulation frame- relay command.

  3.

  For each of the defined PVCs, create a logical subinterface. Specify the port number, followed by a period (.) and the subinterface number. To make troubleshooting easier, it is suggested that the subinterface number matches the DLCI number.

  4.

  Configure an IP address for the interface and set the bandwidth.

  5.

  Configure the local DLCI on the subinterface using the frame-relay interface-dlci command. Configuration Example: R1>enable R1#configure terminal R1(config)#interface serial 0/0/0 R1(config-if)#no ip address R1(config-if)#encapsulation frame-relay R1(config-if)#no shutdown R1(config-if)#exit R1(config-subif)#interface serial 0/0/0.102 point-to-point R1(config-subif)#ip address 192.168.1.245 255.255.255.252 R1(config-subif)#frame-relay interface-dlci R1(config-subif)#end R1#copy running-config startup-config

• Question 57:

  A sporting goods manufacturer has decided to network three (3) locations to improve efficiency in inventory control. The routers have been named to reflect the

  location: Boston, Frankfurt, and Lancaster.

  The necessary networking has been completed at each location, and the routers have been configured with single area OSPF as the routing protocol. The Boston

  router was recently installed but connectivity is not complete because of incomplete routing tables. Identify and correct any problem you see in the configuration.

  Note: The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.

  

  Correct Answer. The question mentioned Boston router was not configured correctly or incomplete so we should check this router first. Click on Host B to access the command line interface (CLI) of Boston router.
  The question mentioned Boston router was not configured correctly or incomplete so we should check this router first. Click on Host B to access the command line interface (CLI) of Boston router.

  Boston>enable (type cisco as its password here) Boston#show running-config

  

  First, remember that the current OSPF Process ID is 2 because we will need it for later configuration. Next notice that in the second “network” command the network and wildcard mask are 192.168.155.0 and 0.0.0.3 which is equivalent to 192.168.155.0 255.255.255.252 in term of subnet mask. Therefore this subnetwork's range is from 192.168.155.0 to 192.168.155.3 but the ip address of s0/0 interface of Boston router is 192.168.155.5 which don't belong to this range -> this is the reason why OSPF did not recognize s0 interface of Boston router as a part of area 0. So we need to find a subnetwork that s0 interface belongs to. IP address of S0 interface: 192.168.155.5/30 Subnet mask: /30 = 1111 1111.1111 1111.1111 1111.1111 1100 Increment: 4 Network address (which IP address of s0 interface belongs to): 192.168.155.4 (because 4 * 1 = 4 < 5) Therefore we must use this network instead of 192.168.155.0 network

  Boston#configure terminal Boston(config)#router ospf 2 Boston(config-router)#no network 192.168.155.0 0.0.0.3 area 0 Boston(config-router)#network 192.168.155.4 0.0.0.3 area 0 Boston(config-router)#end Boston#copy running-config startup-config

  Finally, you should issue a ping command from Boston router to Lancaster router to make sure it works well. Boston#ping 192.168.43.1

• Question 58:

  A network administrator needs to configure port security on a switch. Which two statements are true? (Choose two.)

  A. The network administrator can apply port security to dynamic access ports.
  B. When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
  C. The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.
  D. The network administrator can configure static secure or sticky secure MAC addresses in the voice VLAN.
  E. The network administrator can apply port security to EtherChannels.
  B. When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
  C. The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.

• Question 59:

  What can be done to secure the virtual terminal interfaces on a router? (Choose two.)

  A. Administratively shut down the interface.
  B. Physically secure the interface.
  C. Create an access list and apply it to the virtual terminal interfaces with the access-group command.
  D. Configure a virtual terminal password and login process.
  E. Enter an access list and apply it to the virtual terminal interfaces using the access-class command.
  D. Configure a virtual terminal password and login process.
  E. Enter an access list and apply it to the virtual terminal interfaces using the access-class command.

  ---

  It is a waste to administratively shut down the interface. Moreover, someone can still access the virtual terminal interfaces via other interfaces -> A is not correct.

  We can not physically secure a virtual interface because it is "virtual" -> B is not correct.

  To apply an access list to a virtual terminal interface we must use the "access-class" command. The "access-group" command is only used to apply an access list to a physical interface -> C is not correct; E is correct.

  The most simple way to secure the virtual terminal interface is to configure a username and password to prevent unauthorized login -> D is correct.

• Question 60:

  Refer to the exhibit.
