• Question 301:

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

• Question 303:

  A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection?

  

  A. B. C.
  B

  Cisco High-Level Data Link Controller (HDLC) is the Cisco proprietary protocol for sending data over synchronous serial links using HDLC. So HDLC runs only in Cisco router. PPP is not proprietary protocol it's an open source every cisco router and non-cisco router understand the PPP protocol. So we need to configure the PPP protocol if connection is between cisco and non-cisco router.

• Question 308:

  Instructions

  Enter Cisco IOS commands on device to verify network operation and answer for multiple-choice questions.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

  Click the device icon to gain access to the console of the router. No console or enable passwords are required.

  To access the multiple-choice questions, click the numbered boxes on the left of the top panel.

  This task has four multiple-choice questions. Be sure to answer all four questions before clicking the Next button.

  Scenario

  You are implementing PPP over serial links between R1 router and branch offices. In Phase 1 you must implement and verify PPP and GRE tunnel configurations as mentioned in the topology. In Phase 2 your colleague is expected to do

  NAT and ISP configurations between R1 and ISP router.

  Identify the issues that you encounter during PPP over serial links implementation.

  Routers Branch1, Branch2, and Branch3 connect to Router R1 in the main office over serial links.

  PPP multilink implementation is recommended between R1 and Branch1 routers.

  The GRE tunnel is configured between R2 and Branch2 routers, and traffic between Server farm1 10.10.10.0/24 network and Branch2 LAN 10.10.20.0/24 network, is routed over GRE tunnel using static route.

  You have console access on R1, R2, Branch1, Branch2, and Branch3 devices. Use only show commands to troubleshoot the issues.

  

  Why is the Branch2 network 10.10.20.0/24 unable to communicate with the Server farm1 network 10.10.10.0/24 over the GRE tunnel?

  A. The GRE tunnel destination is not configured on the R2 router.
  B. The GRE tunnel destination is not configured on the Branch2 router.
  C. The static route point to the tunnel0 interface that is misconfigured on the Branch2 router.
  D. The static route points to the tunnel0 interface that is misconfigured on the R2 router.
  C. The static route point to the tunnel0 interface that is misconfigured on the Branch2 router.

  The Branch2 network is communicating to the Server farm, which is connected to R2, via GRE Tunnel so we should check the GRE tunnel first to see if it is in "up/up" state with the "show ip interface brief" command on the two routers. On Branch2:

  

  On R2:

  

  We see interfaces Tunnel0 at two ends are "up/up" which are good so we should check for the routing part on two routers with the "show running-config" command and pay attention to the static routing of each router. On Branch2 we see:

  

  The destination IP address for this static route is not correct. It should be 192.168.24.1 (Tunnel0's IP address of R2), not 192.168.24.10 -> Answer C is correct.

  Note: You can use the "show ip route" command to check the routing configuration on each router but if the destination is not reachable (for example: we configure "ip route 10.10.10.0 255.255.255.0 192.168.24.10" on Branch2, but if

  192.168.24.10 is unknown then Branch2 router will not display this routing entry in its routing table.

  Note: The IP address or configuration may be different in the exam.

• Question 309:

  CORRECT TEXT

  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. Check the answer below
  Check the answer below

  ---

  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. 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
