What two statements are true about SD-WAN? (Choose two.)

Question

Options

• ADistributed policy enforcement does not scale.
• BSD-WAN branches can aggregate different WAN circuits.
• CSD-WAN routers must have specialized hardware to do application routing.
• DSD-WAN supports local breakout for Direct Internet Access

• A
  21% (11)
• B
  70% (37)
• C
  9% (5)

Explanation

B is correct because SD-WAN is specifically designed to aggregate multiple WAN circuits (MPLS, broadband, LTE, etc.) at a branch, load-balancing or failing over across them intelligently. D is correct because SD-WAN enables local internet breakout (Direct Internet Access), allowing branch traffic to exit directly to the internet rather than being backhauled through a data center - a key design goal of SD-WAN.

A is wrong because distributed policy enforcement is actually a strength of SD-WAN; policies are pushed centrally and enforced at each edge device, which scales well across many branches. C is wrong because SD-WAN deliberately runs on commodity or virtual hardware - no specialized ASICs are required; application-aware routing is handled in software, which is a core SD-WAN value proposition.

Memory tip: Think of SD-WAN's two superpowers as "Aggregate and Escape" - it aggregates multiple WAN links (B) and lets traffic escape locally to the internet (D). If an answer suggests SD-WAN requires special hardware or doesn't scale, it's describing the legacy architecture SD-WAN was built to replace.
