Juniper JN0-364 Questions & Answers

Inspect RSVP PATH and RESV state hop by hop and correct the interface or reservation block preventing completion. That could help in a case involving RSVP PATH and RESV signaling. This failure instead depends on RSVP path bandwidth admission; RSVP traffic engineering applies resource reservation and constrained path selection, not merely IP shortest-path routing.

Check downstream label advertisement, selected next hop, and label binding installation before activating the LSP path. That could help in a case involving LDP label binding completeness. This failure instead depends on RSVP path bandwidth admission; RSVP traffic engineering applies resource reservation and constrained path selection, not merely IP shortest-path routing.

Correct the locally expected peer AS and actual neighbor AS identity and validate the BGP OPEN exchange. Its normal acceptance signal would be the peer moves to Established with the agreed local and remote AS values and appropriate session messages. Here the deciding check is different: the intended LSP is admitted on a path satisfying its bandwidth constraints without oversubscribing reserved resources.

Tune the intended OSPF interface costs and verify SPF-selected reachability for the affected destinations. That could help in a case involving OSPF interface metric selection. This failure instead depends on OSPF area LSA propagation; OSPF limits most intra-area LSAs to their areas while ABRs advertise inter-area route information using summary LSAs.

Keep GRES for forwarding continuity and enable the appropriate supported NSB for bridging or NSR or graceful restart for routing sessions as required. This addresses GRES preserves forwarding not protocols, but the reported symptoms arise from OSPF area LSA propagation. For this case, verify instead that the receiving area's LSDB and route table show intended inter-area reachability without copying the source area's full topology.

Configure the same intended OSPF area and compatible interface parameters on both ends of the link. Its normal acceptance signal would be the pair establishes the expected OSPF adjacency with matching area assignment and reachable learned prefixes. Here the deciding check is different: the receiving area's LSDB and route table show intended inter-area reachability without copying the source area's full topology. Applied here, the relevant facts are: An operator expects intra-area router LSAs to flood directly through an ABR into a different area rather than seeing summary information. The question asks which focused engineering action would best correct the fault.

The peer moves to Established with the agreed local and remote AS values and appropriate session messages. It would validate a separate BGP ASN and OPEN negotiation operation, not the change needed here. Confirm instead that comparably eligible paths carry intended MEDs and route selection in the agreed test case follows the planned preference.

Packets to the remote outer endpoint resolve through an ordinary underlay route and GRE probes reach the peer. That establishes GRE endpoint underlay routing rather than a repaired BGP MED neighbor consideration path. The reported failure still requires this evidence: comparably eligible paths carry intended MEDs and route selection in the agreed test case follows the planned preference.

The intended multi-hop peer establishes while IP reachability and any required loopback-source configuration are correct. It would validate a separate EBGP multihop reachability operation, not the change needed here. Confirm instead that comparably eligible paths carry intended MEDs and route selection in the agreed test case follows the planned preference.

This is a useful guard against penultimate hop popping, but it is not scoped to the observed IS-IS LSP database synchronization failure. An appropriate test would show that the two peers converge to consistent current LSP sequence information and compute the same intended topology reachability.

Check interface level settings on both ends during migration and alert on missing expected adjacency levels. That ongoing check is for IS-IS adjacency circuit level; it would not reliably detect recurrence of IS-IS LSP database synchronization. IS-IS LSP sequencing and sequence-number PDUs keep link-state databases synchronized; adjacency status alone does not ensure database parity.

This is a useful guard against IS-IS LAN designated intermediate system, but it is not scoped to the observed IS-IS LSP database synchronization failure. An appropriate test would show that the two peers converge to consistent current LSP sequence information and compute the same intended topology reachability.

The receiving area's LSDB and route table show intended inter-area reachability without copying the source area's full topology. That establishes OSPF area LSA propagation rather than a repaired stable OSPF router identifier path. The reported failure still requires this evidence: every router has a distinct planned router ID and the LSDB tracks the appropriate originating router consistently.

Tagged test frames of the required service size traverse each handoff without oversize or discard counters rising. It would validate a separate provider bridging MTU overhead operation, not the change needed here. Confirm instead that every router has a distinct planned router ID and the LSDB tracks the appropriate originating router consistently.

The best route's cumulative OSPF cost selects the approved path and changes predictably when the alternative fails. That establishes OSPF interface metric selection rather than a repaired stable OSPF router identifier path. The reported failure still requires this evidence: every router has a distinct planned router ID and the LSDB tracks the appropriate originating router consistently.

Configure and verify compatible protocol graceful-restart capability and planned helper behavior between neighbors. This addresses graceful restart peer assistance, but the reported symptoms arise from BFD fast failure detection. For this case, verify instead that A controlled link or peer failure causes BFD Down and timely routing reconvergence rather than waiting for long protocol timers.

The proposal changes LACP aggregation consistency; that is not the failure isolated by the facts. It could leave BFD fast failure detection unresolved even if its own test passed. BFD provides rapid bidirectional path liveness detection; it triggers routing response but is not by itself a replacement route.

Correct the route-reflector client topology and validate reflected path distribution without introducing loops. This addresses IBGP route reflection, but the reported symptoms arise from BFD fast failure detection. For this case, verify instead that A controlled link or peer failure causes BFD Down and timely routing reconvergence rather than waiting for long protocol timers.

This principle matters when troubleshooting MPLS label push swap pop, but using it here mistakes a different failure mode for LDP label binding completeness. The relevant distinction is: LDP supplies label bindings for eligible FECs; IP reachability without a usable label binding does not prove labeled forwarding.

RSVP-TE establishes LSP state through forward PATH and reverse RESV processing; one-way PATH reception is insufficient. Those conditions do not account for the specific LDP label binding completeness problem reported by Stonewell Fiber.

A RIB group can install selected routes into additional routing tables; it does not merge isolated forwarding domains indiscriminately. Those conditions do not account for the specific LDP label binding completeness problem reported by Stonewell Fiber.

Enable compatible OSPFv3 IPv6 operation on the intended peers and validate neighbor and route state. That could help in a case involving OSPFv3 IPv6 neighbor reachability. This failure instead depends on multiprotocol BGP IPv6 AFI; MP-BGP requires the appropriate address-family capability and route processing; an Established IPv4 BGP session alone does not carry IPv6 NLRI.

Verify LAN circuit type, DIS election priorities, and pseudonode LSP origin under the planned shared-segment design. That could help in a case involving IS-IS LAN designated intermediate system. This failure instead depends on multiprotocol BGP IPv6 AFI; MP-BGP requires the appropriate address-family capability and route processing; an Established IPv4 BGP session alone does not carry IPv6 NLRI.

Enable and inspect the relevant IS-IS IPv6 address-family reachability advertisements and verify eligible routes. This addresses IS-IS IPv6 topology TLVs, but the reported symptoms arise from multiprotocol BGP IPv6 AFI. For this case, verify instead that BGP peers exchange the intended IPv6 NLRI and establish resolvable IPv6 next hops.

This measurement tests OSPF area LSA propagation; it cannot distinguish success from failure for the observed OSPF MTU negotiation condition. OSPF database description negotiation can reject incompatible interface MTUs even after hello packets establish initial communication.

The same VLAN numbers can exist where supported without unintended MAC or broadcast leakage across isolated virtual switches. It would validate a separate virtual-switch instance isolation operation, not the change needed here. Confirm instead that the two peers progress through database synchronization to Full and agree on reachable link-state information.

This measurement tests OSPF area identity mismatch; it cannot distinguish success from failure for the observed OSPF MTU negotiation condition. OSPF database description negotiation can reject incompatible interface MTUs even after hello packets establish initial communication.

The proposal changes VSTP per-VLAN root choice; that is not the failure isolated by the facts. It could leave martian source address rejection unresolved even if its own test passed. Martian-address handling protects routing tables from addresses that should not be accepted as normal routable destinations.

The proposal changes filter-based forwarding table selection; that is not the failure isolated by the facts. It could leave martian source address rejection unresolved even if its own test passed. Martian-address handling protects routing tables from addresses that should not be accepted as normal routable destinations.

The proposal changes generated route qualified next hop; that is not the failure isolated by the facts. It could leave martian source address rejection unresolved even if its own test passed. Martian-address handling protects routing tables from addresses that should not be accepted as normal routable destinations.

The check is meaningful for IS-IS LSP database synchronization, but it does not prove that IS-IS L1 and L2 reachability was repaired. IS-IS uses Level 1 within an area and Level 2 between areas; an L1 router needs an appropriate inter-area exit or route leak.

The check is meaningful for IS-IS route redistribution policy, but it does not prove that IS-IS L1 and L2 reachability was repaired. IS-IS uses Level 1 within an area and Level 2 between areas; an L1 router needs an appropriate inter-area exit or route leak.

The LDP session establishes over reachable transport addresses and peers exchange expected label bindings. It would validate a separate LDP transport address reachability operation, not the change needed here. Confirm instead that the Level 1 router has valid remote-area reachability through the intended L1–L2 boundary without learning the entire L2 topology.
