Cisco 200-125 Online Questions & Answers

• Question 231:

  which major ipv6 address type is supported in ipv4 but rarely used ?

  A. Broadcast
  B. multicast
  C. unicast
  D. anycast
  D. anycast

• Question 232:

  Which two statements about the data field in an Ethernet frame are true? (Choose two)

  A. It includes 6 bytes of the source address and 6 bytes of the destination address
  B. The frame is marked as a jumbo frame if the data field is more than 512 bytes in length
  C. It can be padded so that the frame meets the minimum length requirement
  D. It contains a 32-bit CRC.
  E. The frame is marked as a runt if data field is less than 64 bytes in length
  D. It contains a 32-bit CRC.
  E. The frame is marked as a runt if data field is less than 64 bytes in length

• Question 233:

  Refer to the exhibit.

  

  Which two statements are true of the interfaces on Switch1? (Choose two.)

  A. Multiple devices are connected directly to FastEthernet0/1.
  B. A hub is connected directly to FastEthernet0/5.
  C. FastEthernet0/1 is connected to a host with multiple network interface cards.
  D. FastEthernet0/5 has statically assigned MAC addresses.
  E. FastEthernet0/1 is configured as a trunk link.
  F. Interface FastEthernet0/2 has been disabled.
  B. A hub is connected directly to FastEthernet0/5.
  E. FastEthernet0/1 is configured as a trunk link.

  ---

  Carefully observe the information given after command show. Fa0/1 is connected to Switch2, seven MAC addresses correspond to Fa0/1, and these MAC are in different VLAN. From this we know that Fa0/1 is the trunk interface. From the information given by show cdp neighbors we find that there is no Fa0/5 in CDP neighbor. However, F0/5 corresponds to two MAC addresses in the same VLAN. Thus we know that Fa0/5 is connected to a Hub.

  Based on the output shown, there are multiple MAC addresses from different VLANs attached to the FastEthernet 0/1 interface. Only trunks are able to pass information from devices in multiple VLANs.

• Question 234:

  Which two topology state codes are displayed with the show ip eigrp topology command? (Choose two)

  A. A - Active
  B. I - Inter-Area
  C. U - Update
  D. C - Connected
  E. S - Static
  A. A - Active
  D. C - Connected

• Question 235:

  What is the default Syslog facility level?

  A. local4
  B. local5
  C. local6
  D. local7
  D. local7

  ---

  By default, Cisco IOS devices, CatOS switches, and VPN 3000 Concentrators use facility local7 while Cisco PIX Firewalls use local4 to send syslog messages. Moreover, most Cisco devices provide options to change the facility level from their default value.

• Question 236:

  In which circumstance is static routing most useful?

  A. on a stub network
  B. on a network with frequent routingchanges
  C. on a network that experiences frequent link failures
  D. on a large network that must share routes quickly between routers
  A. on a stub network

• Question 237:

  You are transitioning your organization's DHCP and DNS cloud services to new provider. Which two public cloud options can provide a secure and relatively easy migration? (Choose two)

  A. Internet VPN
  B. MPLS VPN
  C. inter-cloud exchange
  D. Internet
  E. Ethernet WAN
  A. Internet VPN
  B. MPLS VPN

• Question 238:

  What two things will a router do when running a distance vector routing protocol? (Choose two.)

  A. Send periodic updates regardless of topology changes.
  B. Send entire routing table to all routers in the routing domain.
  C. Use the shortest-path algorithm to the determine best path.
  D. Update the routing table based on updates from their neighbors.
  E. Maintain the topology of the entire network in its database.
  A. Send periodic updates regardless of topology changes.
  D. Update the routing table based on updates from their neighbors.

  ---

  Distance means how far and Vector means in which direction. Distance Vector routing protocols pass periodic copies of routing table to neighbor routers and accumulate distance vectors. In distance vector routing protocols, routers discover the best path to destination from each neighbor. The routing updates proceed step by step from router to router.

• Question 239:

  At which layer of the OSI model dose PPP perform?

  A. Layer 3
  B. Layer 4
  C. Layer 2
  D. Layer 5
  C. Layer 2

• Question 240:

  Why do large OSPF networks use a hierarchical design? (Choose three.)

  A. to decrease latency by increasing bandwidth
  B. to reduce routing overhead
  C. to speed up convergence
  D. to confine network instability to single areas of the network
  E. to reduce the complexity of router configuration
  F. to lower costs by replacing routers with distribution layer switches
  B. to reduce routing overhead
  C. to speed up convergence
  D. to confine network instability to single areas of the network

  ---

  OSPF implements a two-tier hierarchical routing model that uses a core or backbone tier known as area zero (0). Attached to that backbone via area border routers (ABRs) are a number of secondary tier areas. The hierarchical approach is

  used to achieve the following:

  Rapid convergence because of link and/or switch failures ?

  Deterministic traffic recovery

  ?

  Scalable and manageable routing hierarchy, reduced routing overhead.
