Juniper Networks JN0-683 is the current written exam for the JNCIP-DC certification, replacing Juniper Networks JN0-682 in July 2024. Juniper lists a 90-minute exam with 65 multiple-choice questions and Junos OS 23.4 as the referenced software version. The ExamSnap Juniper Networks JN0-683 page is the live preparation target for professional data-center candidates. The current blueprint centers on data-center deployment and management, IP fabrics, VXLAN, EVPN-VXLAN signaling, data-center interconnect, multitenancy, security, and troubleshooting. These topics are tightly connected: a single endpoint flow can depend on underlay routing, BGP control-plane state, encapsulation,…

Juniper Networks JN0-682 was an earlier written exam for the JNCIP-DC certification. Juniper retired it on July 14, 2024 and introduced Juniper Networks JN0-683 on July 15, 2024. The ExamSnap Juniper Networks JN0-682 page is therefore a historical data-center study resource rather than the current exam target. The underlying topics remain highly reusable. Data-center candidates still need strong IP-fabric routing, BGP, EVPN-VXLAN, multihoming, interconnect design, tenant isolation, and operational troubleshooting. Older labs can deepen those skills, but they should not be used as evidence that the retired blueprint or software…

Juniper Networks JN0-664 is the current written exam for the JNCIP-SP certification. It replaced Juniper Networks JN0-663 in December 2022. Juniper lists the current exam at 90 minutes with 65 multiple-choice questions and Junos OS 22.3 as the referenced software version. The ExamSnap Juniper Networks JN0-664 page is the live preparation destination. The professional service-provider track expects candidates to connect routing protocols with MPLS and customer services. Core areas include advanced OSPF and IS-IS, BGP, class of service, MPLS, traffic engineering, Layer 2 VPNs, Layer 3 VPNs, EVPN, and operational…

Juniper Networks JN0-663 was an earlier written exam for the JNCIP-SP certification. Juniper retired it on December 11, 2022 and introduced Juniper Networks JN0-664 on December 12, 2022. The ExamSnap Juniper Networks JN0-663 page should therefore be used as a historical service-provider routing resource, not as a current exam registration target. Service-provider networking changes more slowly at the protocol level than at the exam-version level. IS-IS, OSPF, BGP, MPLS, traffic engineering, Layer 2 VPNs, Layer 3 VPNs, and policy remain durable subjects. What must be refreshed are software assumptions, feature…

Juniper Networks JN0-650 is the current written exam for the JNCIP-ENT certification, replacing Juniper Networks JN0-649 in November 2025. Official Juniper information lists a 90-minute exam with 65 multiple-choice questions and Junos OS v25.2 as the referenced software version. The ExamSnap Juniper Networks JN0-650 page is the live preparation target for this professional enterprise track. The exam expects more than recognition of routing and switching terminology. Candidates need to interpret advanced Layer 2 behavior, OSPF and BGP decisions, multicast, class of service, enterprise services, EVPN, and troubleshooting evidence. The professional…

Juniper Networks JN0-649 was the professional-level written exam for JNCIP-ENT before Juniper retired it on November 9, 2025. It was replaced the next day by Juniper Networks JN0-650. The ExamSnap Juniper Networks JN0-649 page is therefore best treated as a historical study resource rather than a current registration target. The legacy material still has value because professional enterprise networking concepts do not disappear when an exam version changes. Advanced OSPF, BGP, multicast, Layer 2 behavior, class of service, high availability, and policy-driven troubleshooting remain central to real Junos work. The…

Juniper Networks JN0-637 is the current written exam for the JNCIP-SEC certification. Juniper introduced it after retiring Juniper Networks JN0-636 in June 2024. The ExamSnap Juniper Networks JN0-637 page is therefore the live preparation target for candidates validating professional-level Junos security design, configuration, and troubleshooting skills. The current exam requires JNCIS-SEC and covers advanced security policy, routing and policy-based routing, IPsec and other secure connectivity, high availability including multinode models, automated threat mitigation, and broader security operations. Official details list 90 minutes and 65 multiple-choice questions. Professional preparation should focus…

Juniper Networks JN0-635 was an earlier written exam for the JNCIP-SEC certification. Juniper retired it on October 16, 2022, replaced it with Juniper Networks JN0-636, and later replaced that version with the current Juniper Networks JN0-637. The ExamSnap Juniper Networks JN0-635 page is therefore a two-generation legacy resource. The durable value lies in advanced security reasoning: policy design, NAT, VPNs, high availability, threat controls, identity-aware security, traffic inspection, and operational troubleshooting. The danger is assuming that an old professional-level blueprint still reflects current Junos, Security Director, cloud-security, or threat-mitigation capabilities….

Juniper Networks JN0-481 is the current written exam for the JNCIS-DC certification. Juniper introduced it on June 16, 2025 after retiring the prior data-center specialist exam. The ExamSnap Juniper Networks JN0-481 page is therefore the live preparation target for candidates working with Junos data-center networking and Juniper Apstra. Official objectives combine data-center switching and routing with Apstra intent-based operations. Candidates need to understand EVPN-VXLAN fabrics, routing policy, virtual networks, security policy, multitenancy, data-center interconnect, blueprint operations, graph queries, and intent-based analytics. Current references list Apstra 5.1 and Junos v24.4. The…

Juniper Networks JN0-460 is the current written exam for the JNCIS-MistAI-Wired certification. The exam validates specialist-level skills for operating Mist AI wired assurance, deploying managed switching, and understanding campus fabric architectures. The ExamSnap Juniper Networks JN0-460 page is therefore a live preparation target. Official objectives include switch deployment, templates and site variables, port profiles, dynamic port configuration, service-level expectations, client insights, APIs, campus fabric architecture, EVPN, VXLAN, and the operational relationship between wired assurance and the underlying switching network. The exam is 90 minutes with 65 multiple-choice questions and requires…

Juniper Networks JN0-452 is the current written exam for the JNCIS-MistAI-Wireless certification. Juniper introduced it on September 9, 2024 after retiring Juniper Networks JN0-451 one day earlier. The ExamSnap Juniper Networks JN0-452 page is therefore the live preparation target for candidates specializing in Mist AI wireless operations and assurance. The current blueprint expects more than general Wi-Fi knowledge. Candidates need to understand WLAN design and deployment, Mist configuration, service-level expectations, client troubleshooting, Marvis Virtual Network Assistant, proactive Marvis capabilities, and Juniper Mist location-based services. The exam is 90 minutes with…

Juniper Networks JN0-451 was the specialist exam for Mist AI Wireless before the September 2024 refresh. Juniper retired it on September 8, 2024 and replaced it the next day with the current Juniper Networks JN0-452. The ExamSnap Juniper Networks JN0-451 page is therefore historical preparation rather than a live exam target. Much of the operational reasoning remains useful. Wireless fundamentals, Mist organization and site structure, WLAN configuration, service-level expectations, Marvis-assisted troubleshooting, client experience, and location services still matter. The migration challenge is to update the feature inventory and current objective…

Juniper Networks JN0-364 is the current written exam for the Juniper Networks Certified Specialist, Service Provider Routing and Switching certification. Juniper introduced it after retiring Juniper Networks JN0-363 in February 2026. The ExamSnap Juniper Networks JN0-364 page is therefore the live preparation target for candidates pursuing the specialist service-provider track. The current blueprint expects integrated understanding of routing protocols, routing policy, MPLS, IPv6, tunneling, and high availability. Official exam details list a 90-minute exam with 65 multiple-choice questions and Junos OS 25.2. The breadth means candidates need more than isolated…

Juniper Networks JN0-363 was the Service Provider Routing and Switching, Specialist exam used before the 2026 refresh. Juniper retired it on February 1, 2026 and replaced it with the current Juniper Networks JN0-364. The ExamSnap Juniper Networks JN0-363 page should therefore be treated as legacy preparation with a direct, current successor. The overlap remains substantial because service-provider routing still depends on disciplined understanding of OSPF, IS-IS, BGP, routing policy, MPLS, IPv6, tunnels, and high availability. Candidates can continue using older labs to strengthen those mechanisms, but current readiness must be…

Juniper Networks JN0-351 was the JNCIS-ENT written exam introduced after Juniper Networks JN0-349 and used until the 2026 refresh. Juniper announced Juniper Networks JN0-352 as the new Enterprise Routing and Switching, Specialist exam effective June 8, 2026. The ExamSnap Juniper Networks JN0-351 page should therefore be read as recent legacy material rather than as a live exam target. This version is close enough to the current track to remain useful for many routing and switching mechanisms. OSPF, BGP, routing policy, tunneling, high availability, switching behavior, and Junos troubleshooting remain central…
