  Topology

  

  Simulation Task

  A network is configured with IP connectivity, and the routing protocol between devices started having problems right after the maintenance window to implement network changes. Troubleshoot and resolve a to a fully functional network to ensure that:

  1. Inter-area links have link authentication (not area authentication) using MD5 with the key 1 string CCNP.

  2. R3 is a DR regardless of R2 status while R1 and R2 establish a DR/BDR relationship.

  3. OSPF uses the default cost on all interfaces. Network reachability must follow OSPF default behavior for traffic within an area over intra-area VS inter-area links.

  4. The OSPF external route generated on R4 adds link cost when traversing through the network to reach R2. A network command to advertise routes is not allowed.

• Question 683:

  Refer to the exhibit.

  

  A network engineer is adding a new spoke router into an existing DMVPN Phase 3 tunnel with a hub router to provide secure communication between sites. Which additional configuration must the engineer apply to enable the tunnel to come up?

  A. ip nhrp registration no-unique
  B. ip nhrp server-only non-caching
  C. ip nhrp responder tunnel
  D. ip nhrpnhs 172.23.5.1
  D. ip nhrpnhs 172.23.5.1

• Question 684:

  Examine the output of the show frame-relay map command:

  

  Which of the following statements is true of the configuration of R1?

  A. Neither PVC is up
  B. A frame-relay map statement was used to manually map the IP address to the DLCI on both PVCs
  C. The DLCIs for both PVCs were learned using inverse ARP
  D. Broadcast traffic is not allowed on either PVCs
  C. The DLCIs for both PVCs were learned using inverse ARP

  ---

  The output shows that the Data Link Connection identifiers (DLCI) for both PVCs were learned using inverse ARP. In a Frame Relay topology, Layer 2 addresses are called DLCSI. Each end of a Frame Relay circuit can learn the DLCI of the other end through manual configuration, using the frame-relay map command, or it can be learned dynamically, using a process called inverse ARP. When the addresses are learned using inverse ARP, the output of the show frame-relay map command will indicate that

  by designating the circuit as dynamic. Both PVCs are up, as indicated by the word active in the output for both PVCs.

  A frame-relay map statement not was used to manually map the IP addresses to the DLCI on both PVCs. Were that the case, the output would indicate static in the place where it says dynamic.

  Broadcast and multicast traffic are both allowed across both PVCs, as indicated by the word broadcast after each entry.

• Question 685:

  Refer to the exhibit.

  

  An administrator is troubleshooting a time synchronization problem for the router's time to another Cisco IOS XE-based device that has recently undergone security hardening. Which action resolves the issue?

  A. NTP service is disabled and must be enabled on 10.1.255.40.
  B. Ensure that the CPE router has a valid route to 10.1.255.40 for NTP and rectify if not reachable.
  C. Allow NTP in the ingress ACL on 10.1.255.40 by permitting UDP destined to port 123.
  D. Allow NTP in the ingress ACL on 10.1.255.40 by permitting TCP destined to port 123.
  A. NTP service is disabled and must be enabled on 10.1.255.40.

• Question 686:

  Refer to the exhibit.

  

  An engineer configured SNMP Commies on UserSW2 switch, but the SNMP server cannot upload modified configurations to the switch. Which configuration resolves this issue?

  A. snmp-server community Ciscowruser RW 11
  B. snmp-server group NETADMIN v3 priv read NETVIEW write NETADMIN access 22
  C. snmp-server community CiscOUs3r RW 11
  D. snmp-server group NETVIEW v2c priv read NETVIEW access 11
  A. snmp-server community Ciscowruser RW 11

  The string "Ciscowruser" which is a community string (similar to a per-shared key) should be corrected.

  Confusing components: the question gives the same name to a server-group and to a view. Plus, the question names the password-like strings to some sort of users.

• Question 689:

  A neighboring EIGRP router fails. Its advertised distance (AD) to network 10.10.10.0 was 2 and the feasible distance (FD) was 3.

  Which route will be used to route packets destined for network 10.10.10.0 if the other routes have the following feasible and advertised distances respectively to the destination network?

  A. FD-6 AD-3
  B. FD-4 AD-1
  C. FD-5 AD-3
  D. FD-4 AD-3
  B. FD-4 AD-1

  ---

  When EIGRP loses it best route, called the successor route, it will then use a feasible successor route, if available, to route the packets to that destination. To be considered a feasible successor, the advertised distance, which is the neighboring router's distance, needs to be less than the feasible distance, which is the local router's own metric.

  In this scenario, the feasible distance is 3. The only available feasible successors are the ones that have the advertised distance/feasible distance of 1/4 and 2/4.

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify policy-based routing
