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…

Juniper Networks JN0-349 was an earlier written exam for the JNCIS-ENT certification. Juniper retired it on June 11, 2023 and replaced it with Juniper Networks JN0-351, which has itself now been superseded by Juniper Networks JN0-352. The ExamSnap Juniper Networks JN0-349 page is therefore a historical preparation resource, not a current booking target. That distinction matters because enterprise routing and switching knowledge ages more slowly than an exam blueprint. VLAN behavior, spanning tree, routing policy, OSPF, BGP, redundancy, tunnels, and Junos troubleshooting remain useful engineering subjects even after a specific…

Juniper Networks JN0-336 is the current Security Specialist exam for the JNCIS-SEC credential. Juniper introduced it on September 2, 2025 after retiring Juniper Networks JN0-335 the previous day. The ExamSnap Juniper Networks JN0-336 page should therefore be treated as the live specialist preparation target. Juniper requires JNCIA-SEC as the prerequisite certification. Candidates should already understand foundational SRX security before moving into the specialist objectives: IDP, IPsec VPNs, Advanced Threat Prevention Cloud, high-availability clustering, identity-aware policies, SSL proxy behavior, and Security Director. The current software reference is Junos OS 24.4. This…

Juniper Networks JN0-335 was the JNCIS-SEC specialist exam used until September 1, 2025. Juniper introduced the current Juniper Networks JN0-336 exam on September 2, 2025. The ExamSnap Juniper Networks JN0-335 page should therefore be treated as recent legacy content, not as the live specialist exam. The transition is close enough that much of the conceptual preparation remains useful: IDP, IPsec VPNs, advanced threat prevention, high-availability clustering, identity-aware policies, SSL proxy behavior, and centralized security management. The risk is assuming that a recent predecessor has the same software baseline or exact…

Juniper Networks JN0-334 was a historical Security Specialist exam for the JNCIS-SEC credential. Juniper retired it on January 8, 2023 and introduced Juniper Networks JN0-335 the following day. Since that successor has also been retired, the current path now uses Juniper Networks JN0-336. The ExamSnap Juniper Networks JN0-334 page should therefore be treated as legacy specialist content. It remains useful for durable SRX security concepts, but candidates should not use its exact software references, objective wording, or practice bank as the definition of the current exam. Specialist-level security moves beyond…

Juniper Networks JN0-281 is the current written exam for the JNCIA-DC certification. Juniper introduced it on November 18, 2024 after retiring the previous associate Data Center exam one day earlier. The ExamSnap Juniper Networks JN0-281 page should therefore be treated as the live target for foundational Juniper data center networking preparation. The blueprint covers data center architectures, Layer 2 switching and VLANs, protocol-independent routing, OSPF and BGP, and high-availability mechanisms such as link aggregation, graceful restart, Bidirectional Forwarding Detection, and Virtual Chassis. It also introduces spine-leaf fabrics, underlay and overlay…

Juniper Networks JN0-253 is the current written exam for the JNCIA-MistAI certification. Juniper introduced it on May 5, 2025 after retiring the previous exam one day earlier. The ExamSnap Juniper Networks JN0-253 page should therefore be treated as the live preparation target for candidates working with Mist AI cloud operations and assurance. The current blueprint is broader than a wireless-only exam. It covers Mist cloud fundamentals, user and account roles, organizations and sites, templates and policies, subscriptions and certificates, device onboarding, Wi-Fi Assurance, Wired Assurance, WAN Assurance, Routing Assurance, Access…

Juniper Networks JN0-252 was the JNCIA-MistAI exam used from April 22, 2024 until May 4, 2025. Juniper replaced it with the current Juniper Networks JN0-253 exam on May 5, 2025. The ExamSnap Juniper Networks JN0-252 page should therefore be treated as recent legacy content rather than as a live booking target. This version remains particularly useful because its published scope already covered much of the operational model candidates still need: Mist monitoring and analytics, service-level expectations, packet captures, insights, alerts, audit logs, Marvis actions and queries, location services, and cloud…

Juniper Networks JN0-251 was a historical written exam for the JNCIA-MistAI certification. Juniper ended the exam on April 21, 2024 and introduced Juniper Networks JN0-252 the following day. The ExamSnap Juniper Networks JN0-251 page is therefore useful for historical context, but it should not be used as the final target for current Mist AI preparation. The certification family has continued to evolve quickly. Juniper later retired Juniper Networks JN0-252 on May 4, 2025 and launched the current Juniper Networks JN0-253 exam on May 5, 2025. That sequence makes version control…
