How does SD-WAN typically select the best path for a given application when multiple transports are available?

It always uses the MPLS link because it is the most reliable.

It randomly distributes traffic across all transports.

It uses the first available link in the configuration order.

It monitors link performance (e.g., latency, loss, jitter) and applies policy to choose the optimal path.

An architect is designing an SD-WAN deployment for a company with MPLS, broadband, and LTE links at each branch. The design must allow any transport to carry any application and provide seamless failover if a link drops. Which fundamental SD-WAN concept makes this possible?

A network address translation (NAT) rule on each edge to map all traffic to the broadband interface

A single default route pointing to the MPLS provider's gateway

An overlay network that establishes secure tunnels over the underlay transports, abstracting the physical links

A routing protocol that advertises each physical link as a separate route in the global table

What is a common migration approach when transitioning from a traditional WAN to SD-WAN?

Disabling all existing WAN links before deploying SD-WAN.

Replacing all edge devices at once in a single day.

Using only LTE for all sites during migration.

Phased deployment, starting with pilot sites and gradually expanding.

Part of the Campus and Branch WAN Design domain, which makes up ~33% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~12–20 in this domain), expect 1–2 from this objective — we provide 33 practice questions to prepare you well beyond it.
