Given a VMware SD WAN Branch Edge with Dual Internet links A and B: - Link A has 50 Mb capacity and latency 10ms - Link H has 50 Mb capacity and latency 10ms A database backup of 40Mbps is parted…

Question

Options

• ADMPO will perform pen How load balancing.
• BPacket duplication will take plant to ensure both links are optimized.
• CPackets will be sent nut the highest latency link first as this is low priority bulk traffic
• DLink Aggregation may take place, and both links could be used.

• A
  4% (1)
• B
  11% (3)
• C
  4% (1)
• D
  81% (22)

Explanation

Link Aggregation in VMware SD-WAN allows bulk data flows to be distributed across multiple WAN links simultaneously. Since both links share identical characteristics (50Mbps / 10ms) and the 40Mbps backup is classified as low-priority bulk traffic, the SD-WAN fabric may bond both links together to efficiently carry the load - making D correct.

Why the other options are wrong:

• A - DMPO (Dynamic Multipath Optimization) is designed for real-time, latency-sensitive traffic (voice, video) using per-packet steering, not bulk background transfers.
• B - Packet duplication is a remediation technique for high-priority flows on degraded links; applying it to low-priority bulk traffic would wastefully double bandwidth consumption.
• C - SD-WAN never deliberately routes to the highest latency path; lower latency is always preferred, and here both links have equal 10ms latency anyway.

Memory tip: Think of it this way - "Priority up = DMPO/Duplicate; Priority down = Aggregate/Bond." Real-time traffic gets steering and redundancy; bulk traffic gets bandwidth pooling. If you see "low priority bulk" in a VMware SD-WAN question, think Link Aggregation first.
