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 Juniper retired it on June 11, 2023 and replaced it with Juniper Networks JN0-351, which has itself now been superseded by Juniper Networks JN0-352.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 JN0-281 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…

Juniper Networks JN0-1103 is the current exam for the Juniper Networks Certified Associate, Design credential. The ExamSnap Juniper Networks JN0-1103 page should be studied as a design-decision exam: candidates need to recognize requirements, constraints, trade-offs, and appropriate architectural choices rather than simply repeat configuration knowledge from an operations role. Juniper lists a 90-minute, 65-question multiple-choice exam delivered by Pearson VUE. Current objectives span design methodology, business and technical requirements, physical and logical considerations, high availability, campus and WAN design, data-center architecture, routing and security considerations, and design choices for modern…

Juniper Networks JN0-106 is the current written exam for the Juniper Networks Certified Associate, Junos credential. Juniper introduced it on April 6, 2026 after retiring the previous exam one day earlier. The ExamSnap Juniper Networks JN0-106 destination should therefore be the primary exam page for candidates preparing for JNCIA-Junos now. Juniper lists a 90-minute exam with 65 multiple-choice questions, delivered through Pearson VUE, using Junos OS 21.2 as the published software version. The objective areas cover networking fundamentals, Junos OS fundamentals, user interfaces, configuration basics, operational monitoring and maintenance, routing…

Juniper Networks JN0-105 was the JNCIA-Junos associate exam immediately before the current version. Juniper retired it on April 5, 2026, and launched Juniper Networks JN0-106 on April 6, 2026. The ExamSnap Juniper Networks JN0-105 page should therefore be treated as a recent legacy destination rather than a live booking target. This is an important kind of transition page because much of the foundational knowledge remains relevant while the official exam has changed. Candidates who already studied for the retired version should not discard everything they learned, but they do need…

Juniper Networks JN0-103 was a historical exam for the Juniper Networks Certified Associate, Junos credential. It is no longer the exam candidates should schedule. The ExamSnap Juniper Networks JN0-103 page remains useful as a legacy destination for candidates who encounter old training plans, archived job requirements, or study materials that still reference this version of the JNCIA-Junos path. The current associate exam is Juniper Networks JN0-106. Between the historical exam and the current exam, Juniper also used later JNCIA-Junos versions, including Juniper Networks JN0-104 and Juniper Networks JN0-105. The certification…

The Huawei H31-341 V2.5 exam is associated with HCIP-Transmission V2.5. Current 2026 secondary catalogs continue to identify that exact code and title, while Huawei’s public certification materials establish the associate-to-professional Transmission pathway. At this level, the candidate is expected to reason about transport architecture, capacity, service mapping, protection, operations, and troubleshooting with more depth than the foundational Huawei H31-311 V2.5 track. The specialist presales record Huawei H19-461 V1.0 is also useful context because professional technical knowledge often supports solution planning, even though the exam roles are not identical. The wider…

The Huawei H35-210 V2.5 exam is associated with HCIA-Access V2.5. Huawei’s own certification brochure describes the track as foundational training for engineers who deploy access-network devices, commission basic services, plan optical distribution networks, and troubleshoot routine faults. The published V2.5 content includes access-network overview, network communication principles, xPON and xDSL, PPPoE, DHCP, VLANs, data-service configuration, ODN engineering, and network-management basics. This associate-level track creates the base for Huawei H35-211 V2.5, which moves into professional Access skills. The broader Huawei certifications portfolio also places Access alongside other infrastructure directions such as…

The Huawei H35-211 V2.5 exam is associated with HCIP-Access V2.5. Current 2026 references consistently identify the code and title, and Huawei’s certification portfolio continues to include professional Access training. The professional level builds on the foundational Huawei H35-210 V2.5 track by asking engineers to plan, deploy, optimize, secure, and troubleshoot access networks with a deeper understanding of PON services, protection, quality, voice, multicast, and network management. The broader Huawei certifications structure matters because Access engineering is not isolated from IP networking or operations. Subscriber services depend on Ethernet, VLANs, addressing,…

Huawei H35-581 V2.0 sits in the professional 5G radio-planning and optimization track. The exam is not simply a vocabulary check about fifth-generation mobile networks; it expects candidates to connect radio principles, planning assumptions, feature behavior, performance evidence, and troubleshooting decisions. That makes the strongest preparation approach one that moves continuously between theory and operational consequences rather than treating each topic as an isolated fact. The official Huawei direction for HCIP-5G-RNP&RNO emphasizes deeper radio principles, network planning, RAN feature application, optimization, and industry scenarios. The Huawei H35-581 V2.0 page therefore belongs…

Huawei H35-651 V1.0 is a professional-level 5G core-network exam centered on deployment, operation, signaling, and fault isolation. Its scope reaches beyond knowing the names of network functions. Candidates need to understand how standalone and non-standalone architectures behave, how cloud infrastructure supports core services, and how configuration or signaling defects become visible during real operations. Huawei’s published HCIP-5G-Core material places significant emphasis on standalone core deployment and advanced operations. The Huawei H35-651 V1.0 page should therefore be approached as an operations-and-architecture resource rather than a general introduction to 5G. Because this…

Huawei H35-660 V2.0 is the associate-level HCIA-5G exam and covers a deliberately broad view of fifth-generation mobile technology. The published outline spans 5G evolution, network architecture, key technologies, convergence with newer digital technologies, basic service capabilities, and industry solutions. Candidates therefore need breadth first: a clear map of how radio, transport, core, cloud, devices, and use cases fit together. The Huawei H35-660 V2.0 page is most useful when preparation is organized around that architecture map rather than around disconnected buzzwords. Huawei’s official outline identifies network architecture and key technologies as…
