What is an advantage of next-generation SD-WAN over legacy SD-WAN solutions?

Question

Options

• AIt enables definition of the privileges and responsibilities of administrative users in a network.
• BIt allows configuration to forward logs to external logging destinations, such as syslog servers.
• CIt steers traffic and defines networking and security policies from an application-centric
• DIt provides the ability to push common configurations, configuration updates, and software

• B

• C

• D

Explanation

Option C is correct because next-generation SD-WAN is application-centric - it identifies applications at Layer 7 and uses that awareness to simultaneously steer traffic and enforce both networking and security policies. This is the defining leap over legacy SD-WAN, which routes based on IP/port without native security integration.

Why the distractors are wrong:

• A (admin privilege definitions) describes Role-Based Access Control (RBAC), a general feature of any management platform, not specific to next-gen SD-WAN.
• B (forwarding logs to syslog) is basic logging functionality found in virtually all network devices, including legacy ones.
• D (pushing common configs and software updates) describes centralized template/provisioning management, which legacy SD-WAN already supports.

Memory tip: Think "next-gen = application DNA." Legacy SD-WAN sees packets; next-gen SD-WAN sees apps - and uses that to drive both routing and security in one unified policy. If an answer mentions "application-centric" alongside "security policies," that's your next-gen SD-WAN flag.
