• Question 201:

  -- Exhibit -

  {master:0}[edit interfaces]

  user@switch# show

  ge-0/0/6 {

  unit 0 {

  family ethernet-switching {

  port-mode access; vlan {

  members vlan100;

  }

  }

  }

  }

  ge-0/0/7 {

  unit 0 {

  family ethernet-switching {

  port-mode access;

  vlan {

  members vlan100;

  }

  }

  }

  }

  {master:0}[edit ethernet-swtiching-options]

  user@switch#show

  secure-access-port {

  interface ge-0/0/6.0 {

  mac-limit 1 action drop;

  }

  vlan 100 {

  mac-move-limit 1 action drop;

  }

  }

  -- Exhibit -Referring to the exhibit, what will the mac-move-limit command on ge-0/0/6 do?

  A. Packets will be dropped if the switch detects the same source MAC address on interface ge-0/0/6 and ge-0/0/7.

  B. Packets will be dropped if the switch detects the same source MAC address on two separate interfaces in VLAN 100.

  C. Packets will be dropped and the event will be logged if the switch detects the same source MAC address on two separate interfaces in VLAN 100.

  D. Packets will be dropped and the event will be logged if the switch detects the same source MAC address on ge-0/0/6 and ge-0/0/7.

  Correct Answer: A

  group lab {

  type 65505;

  local-address 192.168.100.1;

  neighbor 192.168.100.2;

  }

  C. [edit] user@router# show protocols bgp group lab { peer-as 65503; local-address 192.168.100.1; neighbor 192.168.100.2; }
