In the context of network design for hybrid multicloud architectures, what role does Software- Defined Networking (SDN) play?

Question

Options

• AIt restricts network configurations to proprietary hardware only
• BIt provides flexibility and control over virtual network resources
• CIt eliminates the need for encryption in data transit
• DIt discourages the use of virtual private clouds (VPCs) and subnetting

• A
  4% (1)
• B
  85% (22)
• C
  4% (1)
• D
  8% (2)

Explanation

SDN decouples the network control plane from the hardware data plane, allowing administrators to programmatically manage and automate virtual network resources across multiple clouds and on-premises environments - making B correct. Option A is wrong because SDN specifically breaks free from proprietary hardware dependency, enabling vendor-agnostic, software-controlled networking. Option C is the opposite of reality: SDN actually facilitates consistent encryption policies across hybrid environments. Option D is wrong because SDN actively enables VPCs and subnetting by making it easier to define, segment, and manage virtual network topologies at scale.

Memory tip: Think of SDN as a "network remote control" - just as a remote lets you control a TV without touching it, SDN lets you control your network without touching physical hardware, giving you flexibility and control from software.
