• Question 946:

  Which command can be used to view the number of times the SPF algorithm has been executed?

  A. show ip ospf
  B. show ip ospf interface
  C. show ip ospf database
  D. show ip ospf neighbor
  A. show ip ospf

  ---

  The show ip ospf command can be used to view the number of times the SPF algorithm has been executed, as shown in the last line of the following output:

  

  The show ip ospf interface command can be used to view neighbor adjacencies. A partial output of the command is shown below. It will not show the number of times the SPF algorithm has been executed.

  

  The show ip ospf neighbor command can also be used to view neighbor adjacencies, although its output is slightly different from the show ip ospf interface command. A partial output of the show ip ospf neighbor command is shown below. It also does not show the number of times the SPF algorithm was executed.

  

  The show ip ospf database command does not show the number of times the SPF algorithm has executed. It shows the contents of OSPF database. Partial output is shown below:

  

  You can make the command output more specific by using parameters with the show ip ospf database command. For example, to view only Type 5 LSAs in the database, you would execute the show ip ospf database external command. Since all Type 5 LSAs are from external networks, this keyword will trim the output to only those types of LSAs. When Type 5 (or external) routes are placed in the database, the next hop address will be 0.0.0.0, which makes it appear as if it is a default route. What this really

  means is that any traffic that needs to go to that external network will be sent to the router that originated the advertisement (the ASBR).

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify OSPF operations

• Question 947:

  An engineer creates a Cisco DNA Center cluster with three nodes, but all the services are running on one host node. Which action resolves this issue?

  A. Restore the link on the switch interface that is connected to a cluster link on the Cisco DNA Center
  B. Click the master host node with all the services and select services to be moved to other hosts
  C. Enable service distribution from the Systems 360 page.
  D. Click system updates, and upgrade to the latest version of Cisco DNA Center.
  C. Enable service distribution from the Systems 360 page.

  ---

  To deploy Cisco DNA Center on a three-node cluster with High Availability (HA) enabled, complete the following procedure:

  Step 1: Configure Cisco DNA Center on the first node in your cluster...

  Step 2: Configure Cisco DNA Center on the second node in your cluster...

  Step 3: Configure Cisco DNA Center on thethird node in your cluster...

  Step 4:Enable high availability on your cluster:

  a.

  In the Cisco DNA Center GUI, click and choose System Settings. The System 360tab is displayed by default.

  b.

  In the Hosts area, clickEnable Service Distribution. After you click Enable Service Distribution, Cisco DNA Center enters into maintenance mode. In this mode, Cisco DNA Center is unavailable until the redistribution of services is completed.

  You should take this into account when scheduling an HA deployment.

• Question 948:

  Refer to the exhibit. An engineer configured IP SLA on R1 to avoid the ISP link flapping problem, but it is not working as designed. IP SLA should wait 30 seconds before switching traffic to a secondary connection and then revert to the primary link after waiting 20 seconds, when the primary link is available and stabilized.

  

  R1# *Nov 18 15:38:59.956: track-sta (700) Change #8 ip sla 700, state Up -> Down *Nov 18 15:38:59.956: %TRACK-6-STATE: 700 ip sla 700 state Up -> Down *Nov 18 15:38:59.956: track-sta (700) ip sla 700 state Up -> Down *Nov 18 15:38:59.956: track-que (700) Queuing CHANGED client event for Static IP Routing *Nov 18 15:38:59.956: track-que (700) Unqueuing CHANGED client event for Static IP Routing *Nov 18 15:39:04.965: track-sta (700) Change #9 ip sla 700, state Down -> Up *Nov 18 15:39:04.965: %TRACK-6-STATE: 700 ip sla 700 state Down -> Up *Nov 18 15:39:04.965: track-sta (700) ip sla 700 state Down -> Up *Nov 18 15:39:04.965: track-que (700) Queuing CHANGED client event for Static IP Routing *Nov 18 15:39:04.965: track-que (700) Unqueuing CHANGED client event for Static IP Routing

  

  Which configuration resolves the issue?

  A. R1(config)#track 700 ip sla 700 R1 (config-track)#delay down 30 up 20
  B. R1 (config)#ip sla 700 R1(config-ip-sla)#delay down 30 up 20
  C. R1 (config)#ip sla 700 R1(config-ip-sla)#delay down 20 up 30
  D. R1(config)#track 700 ip sla 700 R1(config-track)#delay down 20 up 30
  A. R1(config)#track 700 ip sla 700 R1 (config-track)#delay down 30 up 20

  ---

  "wait 30 seconds before switching traffic to a secondary connection" -> delay down 30

  "then revert to the primary link after waiting 20 seconds" -> up 20 Under the track object, you can specify delays so we have to configure delay under "track 700 ip sla 700" (not under "ip sla 700").

• Question 949:

  Refer to the exhibit

  

  While troubleshooting an issue on the network, an engineer notices that a TCP Connect operation failed on port 3000 between R101 and R201. Which command must be configured on R201 to respond to the R101 IP SLA configurations with a control connection on UDP port 1967?

  A. ip sla responder udp-echo ipaddress 1.1.1.1 port 1967
  B. ip sla responder tcp-connect ipaddress 1.1.1.1 port 3000
  C. ip sla responder tcp-connect ipaddress 2.2.2.2 port 3001
  D. ip sla responder
  A. ip sla responder udp-echo ipaddress 1.1.1.1 port 1967
