  • Question
  • You need to allow one host to be permitted to attach dynamically to each switch interface. Which two commands must you configure on your catalyst switch to meet this policy?

    1. Switch(config-if)# ip access-group 10
    2. Switch(config-if)# switchport port-security maximum 1
    3. Switch(config)# access-list 10 permit ip host 1
    4. Switch(config-if)# switchport port-security violation shutdown
    5. Switch(config)# mac-address-table secure


  • Options
  • A. 1 and 3
  • B. 2 and 4
  • C. 2, 3 and 5
  • D. 4 and 5

  • Correct Answer
  • 2 and 4 

    Explanation
    The switchport port-security is an important command, and it's super easy with the CNA; however, from the CLI, you can set the maximum number of MAC addresses allowed into the port, and then set the penalty if this maximum has been passed.
