   Which statement accurately describes the topology of a stitching solution?

   • AIt requires a dedicated ring topology connecting all data centers in a circular fashion.
   • BIt uses a full mesh of point-to-point links between all data centers.
   • CIt uses a single core device to interconnect all edge devices in a star topology.
   • DIt consists of edge devices at each data center connected to a shared IP backbone, forming an overlay network.

   A network operator has implemented a stitching solution to connect two VPLS instances across a DCI. Users report that traffic between the two sites is not working. The operator checks the stitching edge devices and sees that the pseudowire is up, but the VPLS instance on one side is not learning MAC addresses from the other side. What is the most likely cause of this issue?

   • AThe core network is not transporting the VPLS traffic correctly.
   • BThe stitching edge device is not configured to forward traffic between the VPLS instances.
   • CThe pseudowire is not configured with the correct VLAN ID.
   • DThe remote VPLS instance is not configured with the same route target.

   A network administrator is troubleshooting a stitching issue where the pseudowire between two VPLS instances is down. The administrator has verified that the LDP session is up and the routing instances are correctly configured. What should the administrator check next?

   • AThe configuration of the remote stitching edge device.
   • BThe status of the core network.
   • CThe MTU of the pseudowire.
   • DThe MAC address table on the stitching edge device.

   A service provider is designing a DCI solution using stitching to connect multiple customer VPLS instances across two data centers. The provider wants to ensure that the stitching solution is scalable and can support a large number of customers. Which architectural consideration is most important for this design?

   • AUsing a single stitching edge device for all customers.
   • BUsing a single VPLS instance for all customers.
   • CUsing a full mesh of pseudowires between all stitching edge devices.
   • DUsing a hierarchical stitching model with core and edge devices.
