• Question 621:

  Refer to the exhibit. The AP status from Cisco DNA Center Assurance Dashboard shows some physical connectivity issues from access switch interface G1/0/14.

  

  Which command generates the diagnostic data to resolve the physical connectivity issues?

  A. check cable-diagnostics tdr interface GigabitEthernet1/0/14
  B. verify cable-diagnostics tdr interface GigabitEthernet1/0/14
  C. show cable-diagnostics tdr interface GigabitEthernet1/0/14
  D. test cable-diagnostics tdr interface GigabitEthernet1/0/14
  D. test cable-diagnostics tdr interface GigabitEthernet1/0/14

  The Time Domain Reflectometer (TDR) feature allows you to determine if a cable is OPEN or SHORT when it is at fault. To start the TDR test, perform this task:

  Step 1 (Starts the TDRtest):test cable-diagnostics tdr{interface{interface-number}} Step 2 (Displays the TDR test counter information):show cable-diagnostics tdr{interfaceinterface-number} https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9600/software/release/16- 11/configuration_guide/int_hw/b_1611_int_and_hw_9600_cg/checking_port_status_and_c onnectivitypdf

  

• Question 622:

  You are configuring BGP speakers RouterA and RouterB to authenticate one another. The following conditions exist:

  RouterA has an IP address of 192.168.5.3

  RouterB has an IP address of 192.168.5.2

  Both routers reside in AS 6550.

  Which of the following commands will result in successful authentication?

  A. neighbor 192.168.5.2 password routera executed on RouterA neighbor 192.168.5.3 password routerb executed on RouterB
  B. neighbor 192.168.5.2 password routerb executed on RouterA neighbor 192.168.5.3 password routera executed on RouterB
  C. neighbor 192.168.5.2 password routera executed on RouterA neighbor 192.168.5.3 password routera executed on RouterB
  D. neighbor 192.168.5.2 password routera executed on RouterA
  E. neighbor 192.168.5.2 password routerb executed on RouterB
  C. neighbor 192.168.5.2 password routera executed on RouterA neighbor 192.168.5.3 password routera executed on RouterB

  ---

  The following command pair should be used to configure successful authentication:

  neighbor 192.168.5.2 password routera executed on RouterA

  neighbor 192.168.5.3 password routera executed on RouterB

  When setting the keys for authentication, the keys must match. The keys do not need to be the names of either router, and should be a combination of letters numbers and symbols. In this example, both keys are set to the value routera.

  The following two command pairs are incorrect because the keys do not match:

  neighbor 192.168.5.2 password routera executed on RouterA

  neighbor 192.168.5.3 password routerb executed on RouterB

  and

  neighbor 192.168.5.2 password routerb executed on RouterA

  neighbor 192.168.5.3 password routera executed on RouterB

  If you executed the debug ip bgp command to perform troubleshooting with either of these configurations in place, the error message you would see would be as follows:

  %TCP-6-BADAUTH: Invalid MD5 digest from 192.168.5.3 (12293) to 192.168.5.2 (179)

  In the error message, the numbers in parentheses are the port numbers used for the attempted communication.

  The single commands would be incorrect because the key has only been configured on one end:

  neighbor 192.168.5.2 password routera executed on RouterA

  and

  neighbor 192.168.5.2 password routerb executed on RouterB

  If you executed the debug ip bgp command to troubleshoot with either of these configurations in place, you would see the following message:

  %TCP-6-BADAUTH: No MD5 digest from 192.168.5.3 (12293) to 192.168.5.2 (179)

  R3 is learning the 1.0.0.0/24 route through OSPF instead of EIGRP. Which action causes R3 to choose EIGRP to reach the 1.0.0.0/24 network?

  A. Configure EIGRP administrative distance to 120.
  B. Configure EIGRP administrative distance to 110.
  C. Configure OSPF administrative distance to 120.
  D. Configure OSPF administrative distance to 200.
  D. Configure OSPF administrative distance to 200.

• Question 626:

  Which of the following commands should you use to determine both the feasible successors and the non- feasible successors to a given destination network?

  A. show ip route eigrp
  B. show ip eigrp topology
  C. show ip eigrp topology all-links
  D. show ip eigrp topology zero-successors
  C. show ip eigrp topology all-links

  ---

  The show ip eigrp topology all-links command displays both feasible successors and non-feasible successors to a given destination network. This command displays the contents of the topology table and shows all the routes available for a given destination network.

  An example of partial output of the command is below:

  

  The 172.20.2.0/24 network has a feasible successor. This can be determined by looking at the values in the parenthesis next to each route. The second value after the / is the advertised distance from the successor. This value must be less than the value of the feasible distance for a route to be considered a feasible successor. There are two routes for 172.20.2.0/24. The first route listed, via 172.17.3.1, is the successor route. Its cost is 246983122, which matches the feasible distance (FD). The second

  route, via 172.17.1.1, has an advertised distance of 2443698 (the second value in the parentheses after the /). Because this value is less than the FD (2413698), it qualifies as a feasible successor.

  The 172.25.1.0/24 network does not have a feasible successor. The second route listed via 172.17.1.1 has an advertised distance of 2501649, which is greater than the value of the FD, (2416381). Therefore, it is not a feasible successor.

  You should not use the show ip route eigrp command. This command displays only the best metric routes (successors) to a given destination network. A route has the best metric if it has the least feasible distance, which refers to the sum of the metric from a given neighbor to a destination network and the metric to reach that neighbor.

  You should not use the show ip eigrp topology command without the all-links parameter. This command displays only the feasible successors to a given destination network.

  You should not use the show ip eigrp topology zero-successors command because this command lists those routes that do not have a valid successor.

• Question 629:

  R1 and R2 are configured as eBGP neighbors. R1 is in AS100 and R2 is in AS200. R2 is advertising these networks to R1:

  172.16.16.0/20 172.16.3.0/24 172.16.4.0/24 192.168.1.0/24 192.168.2.0/24 172.16.0.0/16

  The network administrator on R1 must improve convergence by blocking all subnets of 172.16.0.0/16 major network with a mask lower than 23 from coming in.

  Which set of configurations accomplishes the task on R1?

  A. ip prefix-list PL-1 deny 172.16.0.0/16 ge 23 ip prefix-list PL-1 permit 0.0.0.0/0 le 32 ! router bgp 100 neighbor 192.168.100.2 remote-as 200 neighbor 192.168.100.2 prefix-list PL-1 in
