   What is a core principle of SD-WAN that distinguishes it from traditional WAN routing?

   • AIt uses static routes to each destination to ensure deterministic path selection
   • BIt uses centralized control and application-aware routing to steer traffic over multiple transports
   • CIt requires MPLS circuits for all site-to-site connectivity
   • DIt relies on a single transport provider for all WAN links

   A network architect is designing a WAN Edge solution for a multi-site enterprise. The architect wants to ensure that the WAN Edge devices can route traffic between sites using the best available path, regardless of the underlying transport. Which feature of Juniper Mist SD-WAN enables this?

   • AThe use of a single WAN link for all traffic.
   • BCentralized management and orchestration of WAN Edge devices.
   • CThe ability to configure static routes on each WAN Edge device.
   • DThe use of MPLS circuits for all WAN links.

   A company uses Juniper Mist SD-WAN to connect branch offices. They want to prioritize business-critical applications over non-critical traffic. Which SD-WAN policy feature should be used to achieve this?

   • AApplication-based traffic steering with QoS marking.
   • BStatic routing to direct traffic to a specific link.
   • CDisabling the non-critical applications on the WAN Edge device.
   • DLink-based load balancing across all WAN links.

   A branch office is experiencing intermittent VoIP quality issues. The WAN Edge device has two links: a primary MPLS link and a backup broadband link. The Mist portal shows that the MPLS link is up but has high latency and jitter. What should the administrator do to resolve the VoIP quality issue?

   • AIncrease the bandwidth on the MPLS link to improve its quality.
   • BDisable the MPLS link and force all traffic to use the broadband link.
   • CKeep the current policy and rely on the automatic failover to switch to broadband when MPLS degrades.
   • DModify the SD-WAN policy for VoIP to use the broadband link as the preferred path, with MPLS as a fallback.

   A company is deploying Juniper Mist SD-WAN and wants to ensure that the WAN Edge devices can establish secure tunnels between sites. The company uses a mix of MPLS and broadband links. What is the role of the WAN Edge device in this architecture?

   • AIt terminates the secure tunnels and applies SD-WAN policies.
   • BIt performs deep packet inspection for all traffic.
   • CIt acts as a central controller that manages all other WAN Edge devices.
   • DIt provides the underlay connectivity for the WAN links.
