  Explanation

  The key word is using unicast map instead of route-map https://www.cisco.com/c/en/us/td/docs/ios/12_2s/feature/guide/fs_bgivt.html

• Question 1223:

  A. Add a new DNS record to resolve the FQDN to the PSN IP address
  B. Create and sign a new CSR that contains the static FQDN entry
  C. Manually configure the hosts file on each user device.
  D. Disable HTTPS on the WLC under the Management menu
  E. Add the FQDN entry under the WLC virtual interface

• Question 1225:

  What is the result of this Python code?

  >>> (3 * 5) % 2

  A. 1
  C. 7
  D. 7.5
  A. 1

• Question 1226:

  Which EIGRP feature allows the use of leak maps?

  A. neighbor
  B. stub
  C. offset-list
  D. address-family
  B. stub

  ---

  Explanation

  If we configured an EIGRP stub router so that it only advertises connected and summary routes. But we also want to have an exception to this rule then we can configure a leak-map. For example:

  R4(config-if)#router eigrp 1 R4(config-router)#eigrp stub R4(config)#ip access-list standard R4_L0opback0 R4(config-std-nacl)#permit host 4.4.4.4 R4(config)#route-map R4_L0opback0_LEAKMAP R4(config-route-map)#match ip address R4_L0opback0 R4(config)#router eigrp 1 R4(config-router)#eigrp stub leak-map R4_L0opback0_LEAKMAP As we can see the leak-map feature goes long with `eigrp stub' command.

• Question 1227:

  Refer to the exhibit.

  

  Which two commands ensure that DSW1 becomes the root bridge for VLAN 10 and 20? (Choose two.)

  A. spanning-tree mst 1 priority 1
  B. spanning-tree mst 1 root primary
  C. spanning-tree mstp vlan 10,20 root primary
  D. spanning-tree mst vlan 10,20 priority root
  E. spanning-tree mst 1 priority 4096
  B. spanning-tree mst 1 root primary
  E. spanning-tree mst 1 priority 4096

  ---

  Explanation

  Priority values are 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344, and 61440. All other values are rejected.

• Question 1228:

  What is the function of the LISP map resolver?

  A. to send traffic to non-LISP sites when connected to a service provider that does not accept nonroutable EIDs as packet sources
  B. to connect a site to the LISP-capable part of a core network, publish the EID-to-RLOC mappings for the site and respond to map-request messages
  C. to decapsulate map-request messages from ITRs and forward the messages to the MS
  D. to advertise routable non-USP traffic from one address family to LISP sites in a different address family
  C. to decapsulate map-request messages from ITRs and forward the messages to the MS

  ---

  Explanation

  Like an MS, a LISP MR connects to the ALT. The function of the LISP MR is to accept encapsulated Map-Request messages from ingress tunnel routers (ITRs), decapsulate those messages, and then forward the messages to the MS responsible for the egress tunnel routers (ETRs) that are authoritative for the requested EIDs.

  When an MR is implemented concurrently with an MS in a private mapping system deployment, the concurrent MS forwards the encapsulated Map-Request messages to the authoritative ETRs. When a LISP ALT is present in the deployment, the MR forwards the Map-Request messages directly over the ALT to the MS responsible for the ETRs that are authoritative for the requested EIDs. An MR also sends Negative Map-Replies to ITRs in response to queries for non-LISP addresses.

• Question 1229:

  Wireless users report frequent disconnections from the wireless network. While troubleshooting, a network engineer finds that after the user is disconnected, the connection re-establishes automatically without any input required. The engineer also notices these message logs:

  AP 'AP2' is down. Reason: Radio channel set. 6:54:04 PM AP 'AP4' is down. Reason: Radio channel set. 6:44:49 PM AP 'AP7' is down. Reason: Radio channel set. 6:34:32 PM

  Which action reduces the user impact?

  A. increase the AP heartbeat timeout
  B. increase BandSelect
  C. enable coverage hole detection
  D. increase the dynamic channel assignment interval
  D. increase the dynamic channel assignment interval

  ---

  Explanation

  These message logs inform that the radio channel has been reset (and the AP must be down briefly). With dynamic channel assignment (DCA), the radios can frequently switch from one channel to another but it also makes disruption. The default DCA interval is 10 minutes, which is matched with the time of the message logs. By increasing the DCA interval, we can reduce the number of times our users are disconnected for changing radio channels.

• Question 1230:

  SIMULATION

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  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.

  Tasks

  Configure OSPF on all three routers according to the topology to achieve these goals:

  1. Configure OSPF without using the “network” statement under the “router ospf” configuration section.

  2. Ensure that all networks are advertised between the routers.

  3. Configure a single command under each Ethernet interface to prevent OSPF neighbors from participating in a DR/BDR election and ensure that no extra host routes are generated.
