  An engineer receives this error message when trying to access another router m-band from the serial interface connected to the console of R1. Which configuration is needed on R1 to resolve this issue?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  The "transport output none" command prevents any protocol connection made from R1.

  Therefore our SSH connection to 192.168.12.2 was refused. In order to fix this problem we can configure "transport output ssh" under "line console 0" of R1.

  Note: The parameter "-l" specifies the username to log in as on the remote machine.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab closes and cannot be reopened.

  Topology

  

  Tasks

  Troubleshoot and resolve the issues to achieve these goals:

  1. Ensure that R1 reaches the prefix 10.6.66.6 without any single point of failure in the path. Do not use a static route or policy-based routing to accomplish this.

  2. Ensure that R1 loopback 1 reaches to R6’s loopback 1 by following the path through R1, R3, R5 to R6 and vice versa. Use metric values K1 = 100000, K2=1, K3=255, K4=10, K5=1500 to modify the default metric in EIGRP if required. Do not use a route-map.

  3. Ensure that on R3, prefix 10.0.56.6/32 uses the SP1 to route to the Internet, whereas prefix 172.16.12.2/32 uses the SP2 to route to the Internet. Do not use BGP to accomplish this. Use the pre-configured route-maps SP1 and SP2 and modify to accomplish the task if required. Use the ping and trace commands from R6 and R2 to prefixes 209.165.202.132 and 209.165.202.128, respectively to verify the results.

• Question 887:

  Examine the sample output of the show ip eigrp topology command.

  

  The network 65.0.0.0 is one of the advertised networks in the routing table. What does the value 128256 represent?

  A. The advertised distance
  B. The feasible distance
  C. The administrative distance
  D. The hop count
  A. The advertised distance

  ---

  The number 128256 after the advertisement for network 65.0.0.0 represents the advertised distance. The advertised distance is the metric that the neighboring router advertised to the local router.

  The feasible distance is the metric that the local router would advertise to the next router. Feasible distance is represented by the number preceding the advertised distance number in the output.

  The administrative distance is a number that represents the trustworthiness of a routing protocol. It allows a router to decide which routing protocol's route to use in the event that more than one protocol advertises a route to the same network.

  The administrative distance is not shown in the output of the show ip eigrp topology command.

  Hop count is a simple metric that RIP uses to compare multiple routes to the same network.

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify policy-based routing

• Question 889:

  Refer to the exhibit.

  

  With the partial configuration of a router-on-a-stick. Clients in VLAN 10 on Gi2 cannot obtain IP configuration from the central DHP server is reachable by a successful ping from the route. Which action resolves the issue?

  A. Configure the ip/ip/dhcp pool f and network 192.168..210.0.255.255/0 commands.
  B. Configure the ip header-address 192-168.265.3 command on the Gi2 10 subinterface.
  C. Configure a valid IP address on the Gi2 interface so that DHCP requests can be forwarded.
  D. Configure the Ip dhcp excluded-address 192.168.255.3 command on the Gi1.10 subinterface.
  B. Configure the ip header-address 192-168.265.3 command on the Gi2 10 subinterface.

• Question 890:

  Refer to the exhibit.

  

  Traffic from the branch network should route through HQ_R1 unless the path is unavailable. An engineer tests this functionality by shutting down interface on the BRANCH router toward HQ_R1 router but 192.168.20.0/24 is no longer reachable from the branch router. Which set of configurations resolves the issue?

  A. HQ_R1(config)# ip sla responder HQ_R1(config)# ip sla responder icmp-echo 172.16.35.2
  B. BRANCH(config)# ip sla 1 BRANCH(config-ip-sla)# icmp-echo 172.16.35.1
  C. HQ_R2(config)# ip sla responder HQ_R2(config)# ip sla responder icmp-echo 172.16.35.5
  D. BRANCH(config)# ip sla 1 BRANCH(config-ip-sla)#icmp-echo 172.16.35.2
  D. BRANCH(config)# ip sla 1 BRANCH(config-ip-sla)#icmp-echo 172.16.35.2

  ---

  In the configuration above, the engineer has made a mistake as he was tracking 172.16.35.6 (the backup path) instead of tracking the main path (172.16.35.2). Therefore,when he shut down the main path, the track 1 was still up so traffic still went through the main path -> it failed. To fix this issue, we just need to correct the tracking interface of the main path.
