Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP request that enters interface s0/0/0 and is destined for an FTP server at IP address 192.168.1.5?
The router matches the incoming packet to the statement that was created by the access-list 201 deny icmp 192.168.1.0 0.0.0.255 any command, continues comparing the packet to the remaining statements in ACL 201 to ensure that no subsequent statements allow FTP, and then the router drops the packet.

What are three characteristics of CSMA/CD? (Choose three.)
  Devices listen to the media and transmit data only when they cannot detect another signal on the media.
  All devices on the media can hear all communications.
  Devices communicate based on a configured priority.
  After a collision occurs, the devices that caused the collision have first priority when attempting to retransmit.
  When a collision occurs, all devices stop transmitting for a randomly generated period of time.
  CSMA/CD uses a token system to avoid collisions.
