Cisco 200-125 Online Questions & Answers

• Question 1:

  Drag and drop the switching concepts from the left onto the correct descriptions on the right.

  Select and Place:

  

  

• Question 2:

  Three switches are connected to one another via trunk ports. Assuming the default switch configuration, which switch is elected as the root bridge for the spanning-tree instance of VLAN 1?

  A. the switch with the highest MAC address
  B. the switch with the lowest MAC address
  C. the switch with the highest IP address
  D. the switch with the lowest IP address
  B. the switch with the lowest MAC address

  ---

  Each switch in your network will have a Bridge ID Priority value, more commonly referred to as a BID. This BID is a combination of a default priority value and the switch's MAC address, with the priority value listed first. The lowest BID will win the election process.

  For example, if a Cisco switch has the default priority value of 32,768 and a MAC address of 11-22-33-44-55-66, the BID would be 32768:11-22-33-44-55-66. Therefore, if the switch priority is left at the default, the MAC address is the deciding factor in the root bridge election.

• Question 3:

  What are the two minimum required components of a DHCP binding? (Choose two.)

  A. a DHCP pool
  B. an exclusion list
  C. a hardware address
  D. an IP address
  E. an ip-helper statement
  C. a hardware address
  D. an IP address

• Question 4:

  Which RPVST+ port state is excluded from all STP operations?

  A. learning
  B. forwarding
  C. blocking
  D. disabled
  D. disabled

• Question 5:

  Which of the following statements describe the network shown in the graphic? (Choose two.)

  

  A. There are two broadcast domains in the network.
  B. There are four broadcast domains in the network.
  C. There are six broadcast domains in the network.
  D. There are four collision domains in the network.
  E. There are five collision domains in the network.
  F. There are seven collision domains in the network.
  A. There are two broadcast domains in the network.
  F. There are seven collision domains in the network.

  ---

  Only router can break up broadcast domains so in the exhibit there are 2 broadcast domains: from e0 interface to the left is a broadcast domain and from e1 interface to the right is another broadcast domain ->. Both router and switch can break up collision domains so there is only 1 collision domain on the left of the router (because hub doesn't break up collision domain) and there are 6 collision domains on the right of the router (1 collision domain from e1 interface to the switch + 5 collision domains for 5 PCs in Production) ->.

• Question 6:

  Which value to use in HSRP protocol election process ?

  A. interface
  B. virtual IP address
  C. priority
  D. router ID
  C. priority

  B. authentication services
  C. network access control
  D. network resilience
  E. path isolation
  F. policy enforcement
  A. virtual network services
  C. network access control
  E. path isolation

• Question 8:

  What happens when you add a switch running an earier IOS version to a SackWise configration running a later version ?

  A. The stack ignores the switch until you update the IOS version on the switch.
  B. The switch software downgrades the IOS version on the stack to match the version on the switch.
  C. The switch software upgrades the IOS version on the switch to match the version on the stack.
  D. The switch keeps its version of IOS and runs normally as part of the stack.
  C. The switch software upgrades the IOS version on the switch to match the version on the stack.
