• Question 111:

  A. STP
  B. VTP
  C. 802.1Q
  D. RSTP
  B. VTP

  Understanding VLAN Trunk Protocol (VTP) http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080094c52.shtml

  Introduction VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco- proprietary protocol that is available on most of the Cisco Catalyst series products.

• Question 112:

  

  OSPF is configured using default classful addressing. With all routers and interfaces operational, how many networks will be in the routing table of R1 that are indicated to be learned by OSPF?

  A. 2
  B. 3
  C. 4
  D. 5
  E. 6
  F. 7
  C. 4

  It already knows about its directly connected ones, only those not directly connected are "Learned by OSPF". OSPF as a link state routing protocol (deals with LSAs rather than routes) does not auto summarize (doesn't support "autosummary").So learned route by OSPF are followed 172.16.2.64/26 172.16.2.228/30 172.16.2.232/30

• Question 113:

  Refer to the exhibit.

  

  What information about the interfaces on the Main_Campus router is true?

  A. The LAN interfaces are configured on different subnets.
  B. Interface FastEthernet 0/0 is configured as a trunk.
  C. The Layer 2 protocol of interface Serial 0/1 is NOT operational.
  D. The router is a modular router with five FastEthernet interfaces.
  E. Interface FastEthernet 0/0 is administratively deactivated.
  B. Interface FastEthernet 0/0 is configured as a trunk.

  ---

  Interface fa0/0 breaks into sub-interfaces and Main_Campus router is connected with switch via fa0/0 .Subinterfaces configured with different subnet mask so the seem switch has multiple vlans and allows communication between these VLAN's. For routing and inter-vlan we need to configure a trunk port. So B will be the correct answer.

• Question 114:

  Scenario

  Refer to the topology. Your company has connected the routers R1. R2. and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

  The EIGRP routing protocol is configured.

  You are required to troubleshoot and resolve the EIGRP issues between the various routers.

  Use the appropriate show commands to troubleshoot the issues.

  

  Which path does traffic take from R1 to R5?

  A. The traffic goes through R2.
  B. The traffic goes through R3.
  C. The traffic is equally load-balanced over R2 and R3.
  D. The traffic is unequally load-balanced over R2 and R3.
  A. The traffic goes through R2.

  Using the "show ip int brief command" on R5 we can see the IP addresses assigned to this router. Then, using the "show ip route" command on R1 we can see that to reach 10.5.5.5 and 10.5.5.55 the preferred path is via Serial 1/3, which we see from the diagram is the link to R2.

  

  

• Question 115:

  Refer to the exhibit.

  

  The company uses EIGRP as the routing protocol. What path will packets take from a host on 192.168.10.192/26 network to a host on the LAN attached to router R1?

  R3# show ip route Gateway of last resort is not set 192 168.20.0/24 is variably subnetted, 6 subnets, 2 masks D 192.168.20.64/26 [90/2195456] via 192.168.20.9, 00:03:31, Serial0/0 D 192.168.20.0/30 [90/2681856] via 192.168.20.9, 00:03:31, Serial0/0 C 192.168.20.4/30 is directly connected, Serial0/1 C 192.168.20.8/30 is directly connected, Serial0/0 C 192.168.20.192/26 is directly connected, FastEthernet0/0 D 192.168.20.128/26 [90/2195456] via 192.168.20.5,00:03:31, Serial0/1

  A. The path of the packets will be R3 to R2 to R1
  B. The path of the packets will be R3 to R1 to R2
  C. The path of the packets will be both R3 to R2 to R1 and R3 to R1
  D. The path of the packets will be R3 to R1
  D. The path of the packets will be R3 to R1

  http://www.orbitco-ccna-pastquestions.com/CCNA---EIGRP-Common-Question.php Looking at the output display above, the LAN attached to router R1 belongs to 192.168.20.64/26 subnet and learned this network via 192.168.20.9 which will be an IP address in 192.168.20.8/30 sub-network. This means that packets destined for 192.168.20.64 will be routed from R3 to R1.

• Question 116:

  Scenario

  Refer to the topology. Your company has connected the routers R1. R2. and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

  The EIGRP routing protocol is configured.

  You are required to troubleshoot and resolve the EIGRP issues between the various routers.

  Use the appropriate show commands to troubleshoot the issues.

  

  Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?

  A. The K values mismatch.
  B. The AS does not match.
  C. The network command is missing.
  D. The passive-interface command is enabled.
  C. The network command is missing.

  ---

  The link from R1 to R6 is shown below:

  

  As you can see, they are both using e0/0. The IP addresses are in the 192.168.16.0 network:

  

  But when we look at the EIGRP configuration, the "network 192.168.16.0" command is missing on R6.

  

  Study the following output taken on R1:

  R1# Ping 10.5.5.55 source 10.1.1.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds:

  Packet sent with a source address of 10.1.1.1

  .......

  Success rate is 0 percent (0/5)

• Question 117:

  Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 to OSPF area 0? (Choose two.)

  A. Router(config)# router ospf 0
  B. Router(config)# router ospf 1
  C. Router(config)# router ospf area 0
  D. Router(config-router)# network 192.168.16.0 0.0.0.255 0
  E. Router(config-router)# network 192.168.16.0 0.0.0.255 area 0
  F. Router(config-router)# network 192.168.16.0 255.255.255.0 area 0
  B. Router(config)# router ospf 1
  E. Router(config-router)# network 192.168.16.0 0.0.0.255 area 0

  In the router ospf

  Command, theranges from 1 to 65535 so o is an invalid number - B is correct but A is not correct. To configure OSPF, we need a wildcard in the "network" statement, not a subnet mask. We also need to assgin an area to this process - E is correct.

• Question 118:

  Refer to the exhibit.

  

  Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?

  A. 10.1.1.2
  B. 10.154.154.1
  C. 172.16.5.1
  D. 192.168.5.3
  C. 172.16.5.1

  CCNA Tutorial: The OSPF Router ID (RID)

  http://www.thebryantadvantage.com/CCNACertificationExamTutorialOSPFRouterIDRID.htm

  When determining the Router ID (RID) of an OSPF-enabled router, OSPF will always use the numerically highest IP address on the router's loopback interfaces, regardless of whether that loopback is OSPF-enabled.

  What if there is no loopback? OSPF will then use the numerically highest IP address of the physical interfaces, regardless of whether that interface is OSPF- enabled.

• Question 119:

  The command show frame-relay map gives the following output:

  Serial 0 (up): ip 192.168.151.4 dlci 122, dynamic, broadcast, status defined, active

  A. 192.168.151.4 represents the IP address of the remote router
  B. 192.168.151.4 represents the IP address of the local serial interface
  C. DLCI 122 represents the interface of the remote serial interface
  D. DLCI 122 represents the local number used to connect to the remote address
  E. broadcast indicates that a dynamic routing protocol such as RIP v1 can send packets across this PVC
  F. active indicates that the ARP process is working
  A. 192.168.151.4 represents the IP address of the remote router
  D. DLCI 122 represents the local number used to connect to the remote address
  E. broadcast indicates that a dynamic routing protocol such as RIP v1 can send packets across this PVC

  DLCI stands for Data Link Connection Identifier. DLCI values are used on Frame Relay interfaces to distinguish between different virtual circuits. DLCIs have local significance because, the identifier references the point between the local router and the local Frame Relay switch to which the DLCI is connected.
