CCNA: Cisco Certified Network Associate — Question 513

What is the function of the controller in a software-defined network?

Answer options

• A. forwarding packets
• B. multicast replication at the hardware level
• C. setting packet-handling policies
• D. fragmenting and reassembling packets

Correct answer: C

Explanation

The controller in a software-defined network is responsible for establishing and managing packet-handling policies, which dictate how data flows through the network. While forwarding packets (A), multicast replication (B), and packet fragmentation (D) are important processes in networking, they are typically handled by network devices rather than the controller itself.
