Cisco 200-125 Online Questions & Answers

• Question 1301:

  Refer to the exhibit.

  

  The technician wants to upload a new IOS in the router while keeping the existing IOS. What is the maximum size of an IOS file that could be loaded if the original IOS is also kept in flash?

  A. 3 MB
  B. 4 MB
  C. 5 MB
  D. 7 MB
  E. 8 MB
  B. 4 MB

  ---

  In this example, there are a total of 8 MB, but 3.8 are being used already, so another file as large as 4MB can be loaded in addition to the original file.

• Question 1302:

  Which command should you use to display detailed information about EBGP peers?

  A. show ip bgp
  B. show ip bgp neighbors
  C. show ip bgp summary
  D. show ip bgp paths
  D. show ip bgp paths

• Question 1303:

  Which two commands can you use to configure an PAgP EtherChannel? (Choose two)

  A. channel-group 10 mode on
  B. channel-group 10 mode auto
  C. channel-group 10 mode passive
  D. channel-group 10 mode desirable
  E. channel-group 10 mode active
  B. channel-group 10 mode auto
  D. channel-group 10 mode desirable

• Question 1304:

  When a router undergoes the exchange protocol within OSPF, in what order does it pass through each state?

  A. exstart state > loading state > exchange state > full state
  B. exstart state > exchange state > loading state > full state
  C. exstart state > full state > loading state > exchange state
  D. loading state > exchange state > full state > exstart state
  B. exstart state > exchange state > loading state > full state

  When OSPF adjacency is formed, a router goes through several state changes before it becomes fully adjacent with its neighbor. Those states are defined in the OSPF RFC 2328, section 10.1. The states are (in order) Down, Attempt, Init, 2Way, Exstart, Exchange, Loading, and Full.

• Question 1305:

  Which feature allows a device to use a switch port that is configured for half-duplex to access the network?

  A. CSMA/CD
  B. IGMP
  C. port security
  D. split horizon
  A. CSMA/CD

  Ethernet began as a local area network technology that provided a half-duplex shared channel for stations connected to coaxial cable segments linked with signal repeaters. In this appendix, we take a detailed look at the half-duplex shared-channel mode of operation, and at the CSMA/CD mechanism that makes it work. In the original half-duplex mode, the CSMA/CD protocol allows a set of stations to compete for access to a shared Ethernet channel in a fair and equitable manner. The protocol's rules determine the behavior of Ethernet stations, including when they are allowed to transmit a frame onto a shared Ethernet channel, and what to do when a collision occurs. Today, virtually all devices are connected to Ethernet switch ports over full-duplex media, such as twisted-pair cables. On this type of connection, assuming that both devices can support the full-duplex mode of operation and that Auto-Negotiation (AN) is enabled, the AN protocol will automatically select the highest-performance mode of operation supported by the devices at each end of the link. That will result in full-duplex mode for the vast majority of Ethernet connections with modern interfaces that support full duplex and AN.

• Question 1306:

  Refer to the exhibit.which two statements about the interface that generated the output are true?(choose two)

  

  A. learned MAC addresses are deleted after five minutes of inactivity
  B. the interface is error-diabled if packets arrive from a new unknown source address
  C. it has dynamically learned two secure MAC addresses
  D. it has dynamically learned three secure MAC addresses
  E. the security violation counter increments if packets arrive from a new unknown source address
  C. it has dynamically learned two secure MAC addresses
  E. the security violation counter increments if packets arrive from a new unknown source address

• Question 1307:

  Which three elements must be used when you configure a router interface for VLAN trunking? (Choose three.)

  A. one physical interface for each subinterface
  B. one IP network or subnetwork for each subinterface
  C. a management domain for each subinterface
  D. subinterface encapsulation identifiers that match VLAN tags
  E. one subinterface per VLAN
  F. subinterface numbering that matches VLAN tags
  B. one IP network or subnetwork for each subinterface
  D. subinterface encapsulation identifiers that match VLAN tags
  E. one subinterface per VLAN

  This scenario is commonly called a router on a stick. A short, well written article on this operation can be found here: http://www.thebryantadvantage.com/RouterOnAStickCCNACertificationExamTutorial.htm

• Question 1308:

  Which feature or protocol determines whether the QOS on the network is sufficient to support IP services?

  A. LLDP
  B. CDP
  C. IP SLA
  D. EEM
  C. IP SLA

• Question 1309:

  Refer to the exhibit.

  

  When running EIGRP, what is required for RouterA to exchange routing updates with RouterC?

  A. AS numbers must be changed to match on all the routers
  B. Loopback interfaces must be configured so a DR is elected
  C. The no auto-summary command is needed on Router A and Router C
  D. Router B needs to have two network statements, one for each connected network
  A. AS numbers must be changed to match on all the routers

  ---

  This question is to examine the understanding of the interaction between EIGRP routers. The following information must be matched so as to create neighborhood. EIGRP routers to establish, must match the following information:

  1.

  AS Number;

  2.

  K value.

• Question 1310:

  Which two steps must you perform to enable router-on-a-stick on a switch? (Choose two.)

  A. Configure an IP route to the VLAN destination network.
  B. Connect the Router to a trunk port.
  C. Configure full duplex.
  D. Configure the subinterface number exactly the same as the matching VLAN.
  E. Assign the access port to a VLAN.
  B. Connect the Router to a trunk port.
  C. Configure full duplex.
