Campus SD-WAN Networking Principles and Planning

An enterprise leases three carrier links: MPLS, Internet1, and Internet2. It requires VoIP service traffic to be preferentially sent over the MPLS link, and low-priority application traffic to be scheduled to other links when the MPLS link is congested. This prevents deterioration in MPLS-link quality from affecting VoIP services. Which traffic-steering algorithm should be selected to meet the enterprise's requirements?

  • A Application priority-based traffic steering
  • B Load balancing-based traffic steering
  • C Link quality-based traffic steering
  • D Bandwidth-based traffic steering
Explanation

Application priority-based traffic steering assigns priorities to applications. When a preferred link is congested, it keeps high-priority application traffic on that link and redirects lower-priority application traffic to lower-priority links, protecting VoIP service quality on MPLS.
