How does SD-WAN utilize multiple transport links, such as MPLS, broadband, and LTE, for intersite connectivity?

It requires all links to be from the same provider

It aggregates them into a single logical link and can steer traffic based on policy and link conditions

It uses only the fastest link at any given time

It uses LTE only as a backup and never for active traffic

What is a characteristic of the hub-and-spoke SD-WAN connectivity model?

All intersite traffic must traverse a central hub site

It requires a dedicated MPLS circuit between each pair of sites

It provides the lowest possible latency between any two sites

Each site has a direct connection to every other site

What is the primary purpose of the overlay network in SD-WAN?

To replace the physical transport with a virtual one

To provide the physical connectivity between sites

To increase the bandwidth of the underlay links

To provide a logical, secure, and policy-driven network that is independent of the underlying transport

What is the role of application identification in SD-WAN application-aware routing?

To compress traffic to save bandwidth

To classify traffic so that appropriate routing policies can be applied

To encrypt traffic for security

To block all non-business applications

An SD-WAN edge device is forwarding traffic from a branch to a data center. The device has two active transports: a low-latency MPLS path and a high-bandwidth broadband path. The traffic is a mix of VoIP and large file transfers. The SD-WAN policy is configured to steer VoIP to MPLS and file transfers to broadband. What is the SD-WAN edge using to make this per-application decision?

Random load balancing across both paths

Deep packet inspection (DPI) and application identification

SD-WAN Intersite Connectivity JN0-1103 Practice Questions (Page 7)

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 37 practice questions to prepare you well beyond it.
