What is one challenge that is pushing customers toward SD-WAN solutions?

Question

Options

• Aneed to move to exclusive MPLS for branch connections
• Black of control over and visibility into WAN traffic
• Cinsufficient security expertise in IT staff at branches
• Dtoo few products and solutions at the branches across their WAN

• A
  70% (19)
• B
  4% (1)
• C
  7% (2)
• D
  19% (5)

Explanation

There appears to be an error in the answer key provided. Based on established networking knowledge, option B is the correct answer, not A.

Why B is correct: A primary driver pushing customers toward SD-WAN is the lack of visibility into and control over WAN traffic. Traditional WAN architectures (particularly hub-and-spoke MPLS designs) make it difficult to monitor application performance, enforce consistent policies, and quickly troubleshoot issues across branch sites. SD-WAN solves this by providing centralized, software-defined visibility and policy control across all WAN links.

Why the distractors are wrong:

• A is incorrect because SD-WAN adoption is driven by the desire to move away from exclusive MPLS dependence (due to cost and rigidity), not toward it. This is the opposite of what actually happens.
• C (insufficient security expertise at branches) is a real IT concern, but it's not the primary challenge cited as a driver for SD-WAN adoption specifically.
• D (too few products at branches) is the opposite of reality - branch proliferation and too many disparate devices is often a problem SD-WAN helps consolidate.

Memory tip: Think "SD-WAN = See your WAN" - the V in visibility is the core selling point. If you can't see or control your traffic, you need SD-WAN.

I'd recommend verifying the answer key against your course material, as A contradicts how SD-WAN is universally positioned in networking curricula (including Cisco, CompTIA, and vendor documentation).
