CCNA: Cisco Certified Network Associate — Question 1320

What are two functions of a Layer 2 switch? (Choose two.)

Answer options

• A. acts as a central point for association and authentication servers
• B. selects the best route between networks on a WAN
• C. moves packets within a VLAN
• D. moves packets between different VLANs
• E. makes forwarding decisions based on the MAC address of a packet

Correct answer: C, E

Explanation

The correct answers, C and E, highlight that a Layer 2 switch is responsible for moving packets within a VLAN and making forwarding decisions based on the MAC address. Options A and B are incorrect because they relate to functions performed by different networking devices, such as authentication servers or routers, rather than Layer 2 switches.
