   A service provider is implementing a stitching solution to connect VPLS instances across a DCI. The provider has two data centers, each with multiple PEs. The provider wants to ensure that the stitching solution is resilient to failures. Which design is most resilient?

   • AUse a single VPLS instance for all customers.
   • BUse a hierarchical model with multiple stitching edge devices in each data center, connected to a core stitching device.
   • CUse a full mesh of pseudowires between all PEs in both data centers.
   • DUse a single stitching edge device in each data center.

   A service provider operates two geographically separated data centers connected by an MPLS backbone. The provider wants to offer a transparent L2VPN service to a customer who has sites in both data centers, without requiring the customer to participate in the provider's routing protocols. The customer's VLANs must appear as a single broadcast domain across both sites. Which stitching approach satisfies this requirement?

   • AConfigure a stitching solution that connects the two VPLS instances in each data center over the MPLS backbone.
   • BUse a pseudowire to directly connect the two customer edge devices across the MPLS backbone.
   • CInterconnect the two data centers using an IP-VPN (L3VPN) service and have the customer route between sites.
   • DDeploy a back-to-back VPLS connection between the two data centers using only Ethernet interfaces.

   An engineer is configuring a stitching solution on a Juniper device. The engineer has created a new routing instance of type 'vpls' for stitching and has configured the pseudowire. However, the engineer is unsure which interface should be used to connect the stitching instance to the local VPLS instance. What should the engineer use?

   • AA physical interface connected to the local VPLS instance.
   • BA VPLS interface (vt- or ps-).
   • CA loopback interface.
   • DAn irb interface.
