JN0-363 Exam Dumps : Service Provider Routing and Switching, Specialist (JNCIS-SP)

In the given exhibit, interfacege-0/0/0is configured to accept VLANs 101-120 andge-0/0/1is configured with flexible VLAN tagging, which means it can tag traffic with any VLAN ID specified. However, only VLAN 200 is explicitly mentioned forge-0/0/1.A. Traffic tagged with VLAN 101 will pass throughge-0/0/0and will egress onge-0/0/1with the same VLAN tag, because the VLAN ID is within the allowed range on both interfaces.B. VLAN 100 is not specified in the allowed VLAN range forge-0/0/0(which is 101-120),nor is it specified underge-0/0/1. Therefore, it will be dropped.References:

In segment routing, SIDs (Segment Identifiers) are used to identify different types of segments that can be traversed. A node SID represents an instruction to route a packet to a particular node, and an adjacency SID represents an instruction to route a packet over a specific link or adjacency between two nodes.

Nonstop routing (NSR) requires both Graceful Routing Engine Switchover (GRES) and commit synchronization to be configured to maintain routing protocol and forwarding state during a Routing Engine switchover. NSR allows the secondary Routing Engine to take over the control plane without the protocols needing to restart, and GRES ensuresthat the forwarding plane continues operating with the current forwarding table. Commit synchronization ensures that configuration changes are synchronized between the primary and backup Routing Engines.
