CCNA: Cisco Certified Network Associate — Question 1010

What is a characteristic of frame switching?

Answer options

• A. populates the ARP table with the egress port
• B. drops received MAC addresses not listed in the address table
• C. stores and forwards frames in a buffer and uses error checking
• D. rewrites the source and destination MAC address

Correct answer: C

Explanation

The correct answer is C because frame switching involves storing frames in a buffer and checking for errors before forwarding them. Option A is incorrect as it describes a function of ARP, not frame switching. Option B is wrong because frame switching typically learns new MAC addresses rather than dropping them, and option D is not a characteristic of frame switching, which focuses on forwarding rather than rewriting addresses.
