• Question 541:

  Refer to the exhibit.

  

  An engineer configures DMVPN and receives the hub location prefix of 10.1.1.0724 on R2 and R3 The R3 prefix of 10 1.3.0/24 is not received on R2. and the R2 prefix 10.1,2.0/24 is not received on R3. Which action reserves the issue?

  A. Split horizon prevents the routes from being advertised between spoke routers it should be disabled with the command no ip split-horizon eigrp 10 on the tunnel interface of R1
  B. There is no spoke-to-spoke connection DMVPN configuration should be modified to enable a tunnel connection between R2 and R3 and neighbor relationship confirmed by use of the show ip eigrp neighbor command
  C. Split horizon prevents the routes from being advertised between spoke routers it should be disabled with the no ip split-horizon eigrp 10 command on the Gi0/0 interface of R1.
  D. There is no spoke-to-spoke connection DMVPN configuration should be modified with a manual neighbor relationship configured between R2 and R3 and confirmed bb use of the show ip eigrp neighbor command.
  A. Split horizon prevents the routes from being advertised between spoke routers it should be disabled with the command no ip split-horizon eigrp 10 on the tunnel interface of R1

  ---

  In this topology, the Hub router will receive advertisements from R2 Spoke router on its tunnel interface. The problem here is that it also has a connection with R3 Spoke on that same tunnel interface. If we don't disable split-horizon, then the Hub will not relay routes from R2 to R3 and the other way around.That is because it received those routes on the same interface tunnel and therefore it cannot advertise back out that same interface (split-horizon rule). Therefore we must disable splithorizon on the Hub router to make sure the Spokes know about each other.

• Question 545:

  A newly Installeo router starts establishing an LDP session from another MPLS router to which it is not directly connected. Which LDP message type responds by target router to the Initiating router using UDP protocol?

  A. notification message
  B. session message
  C. extended discovery message
  D. advertisement message
  C. extended discovery message

• Question 546:

  

  Router R2 operates in a broadcast, multi-access network. Examine the following output of the show ip ospf neighbor command.

  Based on the output, with which routers can R2 establish a full adjacency?

  A. the neighbor at 192.168.5.6
  B. the neighbor at 192.168.5.10
  C. the neighbor at 192.168.5.116
  D. the neighbor at 192.168.5.107
  D. the neighbor at 192.168.5.107

  ---

  R2 can establish a full adjacency with the neighbor at 192.168.5.107 and the neighbor at 192.168.5.165. In a broadcast, multi-access network OSPF network, full adjacencies can only be established with a designated router (DR) or a backup designated router (BDR).

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify OSPF neighbor relationship and authentication

• Question 547:

  You have been asked to troubleshoot the NTP configuration of a router named R70. After executing the show run command, you receive the following partial output of the command that shows the configuration relevant to NTP:

  

  Based on this output, which of the following statements is true?

  A. the time zone is set to 8 hours less than Pacific Standard time
  B. the router will listen for NTP broadcasts on interface E0/0
  C. the router will send NTP broadcasts on interface E0/0
  D. the router will periodically update its software clock
  C. the router will send NTP broadcasts on interface E0/0

  ---

  The router will send NTP broadcast on its E0/0 interface. The command ntp broadcast, when executed under an interface, instructs the router to send NTP broadcast packets on the interface. Any devices on the network that are set with the ntp broadcast client command on any interface will be listening for these NTP broadcasts. While the clients will not respond in any way, they will use the information in the NTP broadcast packets to synchronize their clocks with the information.

  The time zone is not set to 8 hours less than Pacific Standard Time. The value -8 in the command clock timezone PST -8 is the amount of hours offset from UTC time, not from the time zone stated in the command.

  The router will not listen for NTP broadcasts on the interface E0/0. The ntp broadcast command, when executed under an interface, instructs the router to send NTP broadcast packets on the interface. To set the interface to listen and use NTP broadcasts, you would execute the ntp broadcast client command on the interface.

  The router will not periodically update its software clock. The command ntp update-calendar configures the system to update its hardware clock from the software clock at periodic intervals.

  Objective:

  Sub-Objective:

  Configure and verify Network Time Protocol (NTP)

  What does the PE router convert the IPv4 prefix to within an MPLS VPN?

  A. It is defined in RFC 3038 and 3039.
  B. It requires MPLS Traffic Engineering.
  C. It advertises labels per Forwarding Equivalence Class.
  D. It must use Resource Reservation Protocol.
  B. It requires MPLS Traffic Engineering.

• Question 549:

  Router10 is an area system border router (ASBR). The interfaces on Router 10 are configured as below:

  S 0/0 10.0.0.0/8 S0/1 172.16.0.0/8 Fa0/0 192.168.5.0/24 Fa0/1 192.168.6.0/24

  You would like Router 10 to advertise the 192.168.5.0/24 and the 192.168.6.0/24 networks over OSPF in its Type 5 link-state advertisements (LSAs).

  What command set would instruct the router to do this?

  A. RTA10(config)# router ospf 1 RTA10(config-router)# redistribute static
  B. RTA10(config)# router ospf 1 RTA10(config-router)# redistribute connected
  C. RTA10(config)# router ospf 1 RTA10(config)# redistribute connected
  D. RTA10(config)# router ospf 1 RTA10(config-router)# network 192.168.5.0 0.0.0.0 area 1 RTA10(config-router)# network 192.168.6.0 0.0.0.0 area 1
  B. RTA10(config)# router ospf 1 RTA10(config-router)# redistribute connected

  ---

  By default, Type 5 link-state advertisements (LSAs) do not include directly connected networks. To alter this behavior, you must execute the redistribute connected command in OSPF configuration mode. This command instructs the router to include these local interfaces in its advertisements, as follows:

  RTA10(config)# router ospf 1

  RTA10(config-router)# redistribute connected

  You should not execute the command set that includes the redistribute static command. This instructs the router to advertise any statically defined routes that have been configured, instead of those that are local to the router.

  You should not execute the command set that includes RTA10(config)# redistribute connected. The redistribute connected command is shown being executed at the wrong command prompt, and will generate an error message. It must be executed in the OSPF configuration mode and not global configuration mode.

  You should not execute the following command set:

  RTA10(config)# router ospf 1

  RTA10(config-router)# network 192.168.5.0 0.0.0.0 area 1

  RTA10(config-router)# network 192.168.6.0 0.0.0.0 area 1

  The network commands will cause the networks to receive updates from the router, but do not allow them to be advertised in Type 5 LSAs.

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify redistribution between any routing protocols or routing sources

• Question 550:

  Refer to the exhibit. AS 111 wanted to use AS 200 as the preferred path for 172.20.5.0/24 and AS 100 as the backup. After the configuration, AS 100 is not used for any other routes. Whichconfiguration resolves the issue?

  

  

  A. route-map SETLP permit 10 match ip address prefix-list PLIST1 set local-preference 110 route-map SETLP permit 20
  B. route-map SETLP permit 10 match ip address prefix-list PLIST1 set local-preference 99 route-map SETLP permit 20
  C. router bgp 111 no neighbor 192.168.10.1 route-map SETLP in neighbor 192.168.20.2 route-map SETLP in
  D. router bgp 111 no neighbor 192.169.10.1 route-map SETLP in neighbor 192.168.10.1 route-map SETLP out
  B. route-map SETLP permit 10 match ip address prefix-list PLIST1 set local-preference 99 route-map SETLP permit 20

  ---

  There is an implicit deny all at the end of any route-map so all other traffic that does not match 172.20.5.0/24 would be dropped. Therefore we have to add a permitsequence at the end of the route-map to allow other traffic. The default value of Local Preference is 100 and higher value is preferred so we have to set the local preference of AS100 lower than that of AS200.
