Cisco 200-125 Online Questions & Answers

• Question 421:

  Refer to the exhibit.

  

  A network technician is asked to design a small network with redundancy. The exhibit represents this design, with all hosts configured in the same VLAN. What conclusions can be made about this design?

  A. This design will function as intended.
  B. Spanning-tree will need to be used.
  C. The router will not accept the addressing scheme.
  D. The connection between switches should be a trunk.
  E. The router interfaces must be encapsulated with the 802.1Q protocol.
  C. The router will not accept the addressing scheme.

  ---

  Each interface on a router must be in a different network. If two interfaces are in the same network, the router will not accept it and show error when the administrator assigns it.

• Question 422:

  What are two advantages of static routing? (Choose two)

  A. It cannot be used to load-balance traffic over multiple links
  B. It allows the network to respond immediately to changes
  C. It can be implemented easily even in large environments.
  D. It allows the administrator to control the path of traffic
  E. It produces minimal CPU load.
  D. It allows the administrator to control the path of traffic
  E. It produces minimal CPU load.

• Question 423:

  Which device allows users to connect to the network using a single or double radio?

  A. access point
  B. switch
  C. wireless controller
  D. firewall
  A. access point

• Question 424:

  How Eigrp for ipv6 configuration done? (Choose two)

  A. uses process number
  B. neighbor configured directly
  C. configured driectly on interface
  D. configured globally interface
  E. have shutdown feature
  C. configured driectly on interface
  E. have shutdown feature

• Question 425:

  What is the default administrative distance of OSPF?

  A. 90
  B. 100
  C. 110
  D. 120
  C. 110

  ---

  Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a

  routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value.

• Question 426:

  Which function does traffic shaping perform?

  A. it buffers traffic without queuing it
  B. it queues traffic without buffering it
  C. it drops packets to control the output rate
  D. it buffers and queues excess packets
  D. it buffers and queues excess packets

• Question 427:

  Which two benefits are provided by creating VLANs? (Choose two.)

  A. added security
  B. dedicated bandwidth
  C. provides segmentation
  D. allows switches to route traffic between subinterfaces
  E. contains collisions
  A. added security
  C. provides segmentation

  ---

  A VLAN is a switched network that is logically segmented on an organizational basis, by functions, project teams, or applications rather than on a physical or geographical basis.

  Security:

  VLANs also improve security by isolating groups. High-security users can be grouped into a VLAN, possible on the same physical segment, and no users outside that VLAN can communicate with them.

  LAN Segmentation

  VLANs allow logical network topologies to overlay the physical switched infrastructure such that any arbitrary collection of LAN ports can be combined into an autonomous user group or community of interest. The technology logically

  segments the network into separate Layer 2 broadcast domains whereby packets are switched between ports designated to be within the same VLAN. By containing traffic originating on a particular LAN only to other LANs in the same VLAN,

  switched virtual networks avoid wasting bandwidth.

• Question 428:

  Which three commands are required to enable NTP authentication on a Cisco router? (Choose three)

  A. ntp peer
  B. ntp max-associations
  C. ntp authenticate
  D. ntp trusted-key
  E. ntp authentication-key
  F. ntp refclock
  C. ntp authenticate
  D. ntp trusted-key
  E. ntp authentication-key

• Question 429:

  Which three options are the HSRP states for a router? (Choose three.)

  A. initialize
  B. learn
  C. secondary
  D. listen
  E. speak
  F. primary
  B. learn
  D. listen
  E. speak

  HSRP States

  

• Question 430:

  Refer to the exhibit.

  

  A new subnet with 60 hosts has been added to the network. Which subnet address should this network use to provide enough usable addresses while wasting the fewest addresses?

  A. 192.168.1.56/26
  B. 192.168.1.56/27
  C. 192.168.1.64/26
  D. 192.168.1.64/27
  C. 192.168.1.64/26

  ---

  A subnet with 60 host is 2*2*2*2*2*2 = 64 -2 == 62 6 bits needed for hosts part. Therefore subnet bits are 2 bits (8-6) in fourth octet. 8bits+ 8bits+ 8bits + 2bits = /26 /26 bits subnet is 24bits + 11000000 = 24bits + 192 256 ?192 = 64 0 -63 64 ?127
