Cisco 200-120 Online Questions & Answers

• Question 291:

  Users on the 172.17.22.0 network cannot reach the server located on the 172.31.5.0 network. The network administrator connected to router Coffee via the console port, issued the show ip route command, and was able to ping the server.

  

  Based on the output of the show ip route command and the topology shown in the graphic, what is the cause of the failure?

  A. The network has not fully converged.
  B. IP routing is not enabled.
  C. A static route is configured incorrectly.
  D. The FastEthernet interface on Coffee is disabled.
  E. The neighbor relationship table is not correctly updated.
  F. The routing table on Coffee has not updated.
  C. A static route is configured incorrectly.

  ---

  The default route or the static route was configured with incorrect next-hop ip address 172.19.22.2. The correct IP address will be 172.18.22.2 to reach server located on 172.31.5.0 network. IP route 0.0.0.0 0.0.0.0 172.18.22.2

• Question 292:

  Which two statements about IPv6 and routing protocols are true? (Choose two.)

  A. Link-local addresses are used to form routing adjacencies.
  B. OSPFv3 was developed to support IPv6 routing.
  C. EIGRP, OSPF, and BGP are the only routing protocols that support IPv6.
  D. Loopback addresses are used to form routing adjacencies.
  E. EIGRPv3 was developed to support IPv6 routing.
  A. Link-local addresses are used to form routing adjacencies.
  B. OSPFv3 was developed to support IPv6 routing.

• Question 293:

  What is a global command?

  A. a command that is set once and affects the entire router
  B. a command that is implemented in all foreign and domestic IOS versions
  C. a command that is universal in application and supports all protocols
  D. a command that is available in every release of IOS, regardless of the version or deployment status
  E. a command that can be entered in any configuration mode
  A. a command that is set once and affects the entire router

  ---

  When you enter global configuration mode and enter a command, it is applied to the running configuration file that is currently running in ram. The configuration of a global command affects the entire router. An example of a global command

  is one used for the hostname of the router.

  Incorrect Answers:

  A. Global configuration commands must be performed while in global configuration mode. For example, when you are in the interface configuration mode, you most likely will need to exit out into global mode to type in the commands.

  B. Global commands do not necessarily support every protocol.

  C. This is not necessarily true, since there are certain global commands that are supported on one feature set that are not on a different feature set of IOS.

  E. Global commands can become outdated, and can be replaced by newer commands in the newer releases of IOS.

• Question 294:

  DRAG DROP

• Question 295:

  Which two commands can you enter to verify that a configured NetFlow data export is operational? (Choose two.)

  A. show ip flow export
  B. show ip cache flow
  C. ip flow ingress
  D. ip flow egress
  E. interface ethernet 0/0
  F. ip flow-export destination
  A. show ip flow export
  B. show ip cache flow

• Question 296:

  The network administrator needs to address seven LANs. RIP version 1 is the only routing protocol in use on the network and subnet 0 is not being used. What is the maximum number of usable IP addresses that can be supported on each LAN if the organization is using one class C address block?

  A. 8
  B. 6
  C. 30
  D. 32
  E. 14
  F. 16
  C. 30

  ---

  Since there is one class C network that means 256 total IP addresses. Since we need 7 LAN blocks and we cannot use the first one (subnet 0) we take 256/8=32 hosts. However, since we need to reserve the network and broadcast addresses for each of these subnets, only 30 total IP addresses are usable.

• Question 297:

  In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

  A. during high traffic periods
  B. after broken links are re-established
  C. when upper-layer protocols require high reliability
  D. in an improperly implemented redundant topology
  E. when a dual ring topology is in use
  D. in an improperly implemented redundant topology

  ---

  If we connect two switches via 2 or more links and do not enable STP on these switches then a loop (which creates multiple copies of the same unicast frame) will occur. It is an example of an improperly implemented redundant topology.

• Question 298:

  DRAG DROP

  Drag the Frame Relay acronym on the left to match its definition on the right. (Not all acronyms are used.)

• Question 299:

  Refer to the exhibit.

  

  The output that is shown is generated at a switch. Which three statements are true? (Choose three.)

  A. All ports will be in a state of discarding, learning, or forwarding.
  B. Thirty VLANs have been configured on this switch.
  C. The bridge priority is lower than the default value for spanning tree.
  D. All interfaces that are shown are on shared media.
  E. All designated ports are in a forwarding state.
  F. This switch must be the root bridge for all VLANs on this switch.
  A. All ports will be in a state of discarding, learning, or forwarding.
  C. The bridge priority is lower than the default value for spanning tree.
  E. All designated ports are in a forwarding state.

  ---

  From the output, we see that all ports are in designated role (forwarding state).

  The command "show spanning-tree vlan 30 only shows us information about VLAN 30. We don't know how many VLAN exists in this switch ->.

  The bridge priority of this switch is 24606 which is lower than the default value bridge priority 32768.

  All three interfaces on this switch have the connection type "p2p", which means Point-to-point environment ?not a shared media.

  The only thing we can specify is this switch is the root bridge for VLAN 3o but we cannot guarantee it is also the root bridge for other VLANs.

• Question 300:

  Which spanning-tree protocol rides on top of another spanning-tree protocol?

  A. MSTP
  B. RSTP
  C. PVST+
  D. Mono Spanning Tree
  A. MSTP
