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 Juniper retired it on June 11, 2023 and replaced it with Juniper Networks JN0-351, which has itself now been superseded by Juniper Networks JN0-352.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

Juniper Networks JN0-232 is the current associate-level Security exam for the JNCIA-SEC credential. Juniper introduced it on August 4, 2025 after ending the previous version on August 3, 2025. The ExamSnap Juniper Networks JN0-232 page should therefore be treated as the live target for candidates building foundational Juniper security skills. The current blueprint focuses on SRX Series service gateways, Junos security objects, policies, Network Address Translation, content security, and monitoring or troubleshooting. Juniper lists no prerequisite certification and describes the exam as a 90-minute assessment with 65 multiple-choice questions. That…

Juniper Networks JN0-231 was the associate-level Security exam used for the JNCIA-SEC credential until August 3, 2025. Juniper replaced it with the current Juniper Networks JN0-232 exam on August 4, 2025. The ExamSnap Juniper Networks JN0-231 page should therefore be read as historical preparation material, not as a live registration target. The older exam established security foundations around SRX service gateways, Junos security objects, policies, NAT, IPsec and content-security concepts, plus monitoring and troubleshooting. Those ideas remain valuable because the current JNCIA-SEC path still expects candidates to understand traffic processing,…

Juniper Networks JN0-224 is the current written exam for the Juniper Networks Certified Associate, Automation and DevOps credential. Juniper introduced it on February 17, 2025 after retiring the prior version one day earlier. The ExamSnap Juniper Networks JN0-224 page should therefore be treated as a live preparation target rather than as historical automation content. The current blueprint combines DevOps concepts with the interfaces and data structures used to automate Junos devices. Candidates need working familiarity with NETCONF and XML, JSON and YAML, Python, Junos PyEZ, JSNAPy, Jinja2, remote procedure calls,…

Juniper Networks JN0-223 was an associate-level Automation and DevOps exam for the JNCIA-DevOps credential. Juniper retired it on February 16, 2025 and introduced the current Juniper Networks JN0-224 exam on February 17, 2025. The ExamSnap Juniper Networks JN0-223 page should therefore be read as recent legacy content, not as a live exam registration target. The historical exam remains conceptually useful because the JNCIA-DevOps track continues to emphasize automation foundations for Juniper devices: DevOps practices, Junos automation interfaces, NETCONF and XML, structured data such as JSON and YAML, Python, Junos PyEZ,…

Juniper Networks JN0-214 is the current exam for the Juniper Networks Certified Associate, Cloud credential. The ExamSnap Juniper Networks JN0-214 destination should be the primary exam page for candidates preparing now, replacing older associate versions that appear in archived courses and search results. Juniper lists a 90-minute exam with 65 multiple-choice questions delivered through Pearson VUE. The published software baseline includes Contrail 22.4, OpenStack Zed, Kubernetes 1.24, and OpenShift 4.10. Current objectives span cloud fundamentals, networking, virtualization, OpenStack, Kubernetes, OpenShift, and cloud networking concepts relevant to Juniper environments. The exam…

Juniper Networks JN0-211 was an earlier exam for the Juniper Networks Certified Associate, Cloud credential. Juniper retired it on February 13, 2022 and moved the certification through later versions. The current ExamSnap destination for the live associate exam is Juniper Networks JN0-214, while the Juniper Networks JN0-211 page should be treated as historical. The legacy exam is still useful for understanding the certification lineage because JNCIA-Cloud has consistently focused on cloud architecture, networking, virtualization, orchestration, and the role of Juniper technologies within cloud environments. The specific platforms and software versions…

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…
