Cisco 200-125 Online Questions & Answers

• Question 41:

  Which symptom most commonly indicates that two connecting interface are configured with a duplex mismatch?

  A. an interface with up/down state
  B. an interface with down/down state
  C. late collisions on the interface
  D. the spanning tree process shutting down
  C. late collisions on the interface

• Question 42:

  Which type of routing protocol operates by using first information from each device peers?

  A. link-state protocols
  B. distance-vector protocols
  C. path-vector protocols
  D. exterior gateway protocols
  A. link-state protocols

• Question 43:

  

  Refer to the exhibit. Which switch in this configuration becomes the root bridge?

  A. SW1
  B. SW2
  C. SW3
  D. SW4
  C. SW3

• Question 44:

  Which port-security feature allows a switch to learn MAC addresses dynamically and add them to the running configuration?

  A. security violation restrict mode
  B. switch port protection
  C. sticky learning
  D. security violation protect mode
  C. sticky learning

  ---

  You can configure an interface to convert the dynamic MAC addresses tosticky secure MAC addresses and to add them to the running configuration by enabling sticky learning. To enable sticky learning, enter the switchport port-security mac-address sticky interface configuration command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses.

• Question 45:

  which add prefix does OSPFv3 use when multiple IPv6 address are configured on a single interface ?

  A. all prefix on the interface
  B. the prefix that the administrator configure for OSPFv3 use
  C. the lowest prefix on the interface
  D. the highest prefix on the interface
  A. all prefix on the interface

In OSPFv3, all address prefixes on an interface are included by default. You cannot select some address prefixes to be imported into OSPFv3; either all address prefixes on an interface are imported, or no address prefixes on an interface are imported."

• Question 46:

  Which two statements about Ethernet standards are true? (Choose two)

  A. Ethernet is defined by IEEE standard 802.2.
  B. Ethernet is defined by IEEE standard 802.3.
  C. Ethernet 10BASE-T does not support full-duplex.
  D. When an Ethernet network uses CSMA/CD, it terminates transmission as soon as a collision occurs.
  E. When an Ethernet network uses CSMA/CA. it terminates transmission as soon as a collision occurs.
  B. Ethernet is defined by IEEE standard 802.3.
  D. When an Ethernet network uses CSMA/CD, it terminates transmission as soon as a collision occurs.

• Question 47:

  What command visualizes the general NetFlow data on the command line?

  A. show ip flow export
  B. show ip flow top-talkers
  C. show ip cache flow
  D. show mls sampling
  E. show mls netflow ip
  C. show ip cache flow

  ---

  The following is an example of how to visualize the NetFlow data using the CLI. There are three methods to visualize the data depending on the version of Cisco IOS Software. The traditional show command for NetFlow is "show ip cache flow" also available are two forms of top talker commands. One of the top talkers commands uses a static configuration to view top talkers in the network and another command called dynamic top talkers allows real-time sorting and aggregation of NetFlow data. Also shown is a show MLS command to view the hardware cache on the Cisco Catalyst 6500 Series Switch. The following is the original NetFlow show command used for many years in Cisco IOS Software. Information provided includes packet size distribution; basic statistics about number of flows and export timer setting, a view of the protocol distribution statistics and the NetFlow cache.

  The "show ip cache flow" command displays a summary of the NetFlow accounting statistics.

  What does split horizon prevent?

  A. routing loops, link state
  B. routing loops, distance vector
  C. switching loops, STP
  D. switching loops, VTP
  B. routing loops, distance vector

• Question 49:

  Which issue is a common cause of runts?

  A. overloaded hardware queues
  B. native VLAN mismatch
  C. duplex mismatch
  D. collisions on the wire
  D. collisions on the wire

• Question 50:

  Why applications that are installed on PCs in R2 LAN network 10.100.20.0/24 are unable to communicate with server1?

  

  A. A standard ACL statement that is configured on Rl is blocking the traffic sourced from R2 LAN network.
  B. A standard ACL statement that is configured on Rl is blocking the traffic sourced from Serverl network.
  C. A standard ACL statement that is configured on R2 is blocking the traffic sourced from Serverl network.
  D. A standard ACL statement that is con^gured on R2 is blocking the traffic sourced from R2 LAN network.
  C. A standard ACL statement that is configured on R2 is blocking the traffic sourced from Serverl network.
