CCNA 2 v7 Modules 1 – 4: Switching Concepts, VLANs, and InterVLAN Routing Exam Answers 20
Explanation: The first step a switch does when processing a frame is to see if the source MAC address is in the MAC address table. If the address is not there, the switch adds it. The switch then examines the destination MAC address and compares it to the MAC address table. If the address is in the table, the switch forwards the frame out the corresponding port. If the address is missing from the table, the switch will forward the frame to all ports except the port through which the frame arrived.
21. What information is added to the switch table from incoming frames?

  • source MAC address and incoming port number
  • destination MAC address and incoming port number
  • source IP address and incoming port number
