The correct answer is A. Design a SD-WAN solution to integrate with the cloud provider; use SD-WAN to connect branch. SD-WAN directly addresses all three stated business outcomes: it reduces costs compared to dedicated MPLS circuits, centralizes management to reduce administrative overhead, and natively integrates with major cloud providers (AWS, Azure, GCP) to deliver cloud services directly…
Question
A network architect is designing an expansion solution for the branch office network and requires the following business outcomes:
- Maximize cost savings with reduced administration overhead
- Easily expand connectivity to the cloud
- Use cloud-based services to the branch offices
Which of the following should the architect do to best meet the requirements?
Options
- ADesign a SD-WAN solution to integrate with the cloud provider; use SD-WAN to connect branch
- BDesign point-to-site branch connectivity for offices to headquarters; deploy ExpressRoute and/or
- CDesign an MPLS architecture for the branch offices and site-to-site VPN between headquarters
- DDesign a dark fiber solution for headquarters and branch offices' connectivity; deploy point-to-site

Explanation
SD-WAN directly addresses all three stated business outcomes: it reduces costs compared to dedicated MPLS circuits, centralizes management to reduce administrative overhead, and natively integrates with major cloud providers (AWS, Azure, GCP) to deliver cloud services directly to branch offices. Option B (point-to-site with ExpressRoute) is more complex and expensive. Option C (MPLS with site-to-site VPN) is costly and has high administrative overhead - the opposite of the goal. Option D (dark fiber) is extremely expensive and inflexible. SD-WAN is specifically designed for this use case: cost-effective, cloud-integrated branch connectivity.
