Cisco 300-715 SISE tests the ability to implement Cisco Identity Services Engine (ISE), where network admission depends on identity, device attributes and policy. It is an active CCNP Security concentration in October 2026, not a stand-alone award of the entire professional-level certification. Cisco lists SISE as a 90-minute US$300 exam, subject to applicable registration conditions. Passing earns Cisco Certified Specialist – Security Identity Management Implementation; CCNP Security additionally requires its core exam. The Cisco 300-715 SISE ExamSnap resource can supplement preparation, but Cisco’s current objectives define the exam scope. Understand…

Choosing a CCNA book in late 2026 requires more care than simply buying the newest title with “Cisco CCNA 200-301” on the cover. Cisco is in a transition period: the current CCNA v1.1 exam remains available through February 2, 2027, and CCNA v2.0 begins February 3, 2027. A useful book therefore has to match the exam version you actually plan to take. The underlying networking foundation remains durable. IPv4 and IPv6 addressing, Ethernet switching, VLANs, routing, IP services, security, wireless, and automation are not disappearing. What changes between blueprint revisions…

The 300-435 ENAUTO exam changed materially in 2026. Effective February 3, Cisco moved ENAUTO to v2.0 and positioned it inside both CCNP Enterprise and CCNP Automation. The current exam remains 90 minutes, but the scope is broader than “know Python and call a REST API.” It now emphasizes device-level automation, controller-based workflows, operations, validation, and AI in automation across IOS XE, Meraki, Catalyst Center, Catalyst SD-WAN, ISE, and ThousandEyes. That shift changes preparation. Start with network automation fundamentals but treat them as engineering disciplines: source control, data models, idempotence, error…

Cisco 300-425 ENWLSD is no longer an active certification exam. Cisco retired Designing Cisco Enterprise Wireless Networks (300-425) on March 18, 2026 and identified 300-110 WLSD, Designing Cisco Wireless Networks, as its replacement. The change is more than a code update: wireless design now sits inside Cisco’s dedicated CCNP Wireless certification track rather than being treated as an Enterprise concentration in the old structure. That means anyone arriving at older 300-425 study material needs to separate historical knowledge from the current certification path. The former exam remains useful as a…

The 300-420 ENSLD exam is the CCNP Enterprise concentration focused on design rather than implementation. Cisco’s current v1.1 exam is 90 minutes and covers advanced addressing and routing solutions, advanced enterprise campus networks, WAN, security services, network services, Software-Defined Access, and automation-related design concepts. The wording changes the study method: you are often deciding among valid technologies based on requirements, not proving that one command is syntactically correct. Design questions reward trade-off thinking. Availability can increase complexity. Summarization can improve scale but hide detail. Centralization can simplify control while increasing…

ENARSI is one of the most practical CCNP Enterprise concentration exams because it asks candidates to reason about networks that are already complex, already carrying production traffic, and already capable of failing in several places at once. Cisco’s current 300-410 ENARSI v1.1 exam validates implementation and troubleshooting across advanced Layer 3 technologies, VPN services, infrastructure security, infrastructure services, and infrastructure automation. Passing 300-410 ENARSI earns the Cisco Certified Specialist – Enterprise Advanced Infrastructure Implementation certification and can satisfy the concentration requirement for CCNP Enterprise. The exam is currently 90 minutes,…

The Cisco 200-901 exam still exists, but the certification around it has changed. Cisco renamed the DevNet Associate certification to CCNA Automation. The exam number stayed 200-901, while the current exam name is Automating Networks Using Cisco Platforms (CCNAAUTO). Cisco describes the change at associate level as a new name for the same automation-focused certification path rather than a completely different credential. That makes older DEVASC articles partly historical and partly still useful. The underlying skills—software development, APIs, application deployment, security, scripting, testing, and infrastructure automation—remain central. What changed is…

Cisco’s active 200-201 CCNACBR v1.2 examination, Understanding Cisco Cybersecurity Operations Fundamentals, earns the CCNA Cybersecurity certification. Earlier materials use CBROPS and CyberOps Associate names, but the current issuer objectives cover security concepts, monitoring, host-based analysis, network intrusion analysis, and security policies and procedures. Use the current code and exam guide before selecting preparation resources. Many candidates underestimate how application-focused this exam is compared to purely theoretical tests. Cisco does not just want you to define terms. It wants to see that you can apply security concepts to realistic scenarios, interpret…

Cisco 300-410 ENARSI is valuable because advanced enterprise routing problems rarely fail in simple ways. A route can be learned from the wrong source, redistributed back toward its origin, filtered by policy, hidden by summarization, installed in the wrong VRF, or preferred because an attribute changed somewhere else in the topology. The professional skill is not knowing more commands; it is being able to explain why the network selected a path and what will happen when that path changes. The current Cisco 300-410 ENARSI v1.1 exam is 90 minutes and…

Meraki’s cloud-managed dashboard brings device configuration, monitoring, and troubleshooting into one management service. It can simplify distributed network operations, but a dashboard does not make every application path or client event visible. Engineers still need to understand the design, which telemetry is supported, and whether a configuration change has actually reached a device. Six dashboard capabilities are especially useful for everyday decisions: topology and client visibility, security policy, Auto VPN, wireless radio management, alerting and automation, and firmware governance. For a broader platform selection question, our Cisco Meraki versus Aruba…

CCENT and ICND1 still appear in study plans, old books, archived course notes, and search results, but they are no longer current Cisco certification targets. Cisco retired the 100-105 ICND1 exam and the old CCENT/CCNA Routing and Switching path in February 2020, replacing that structure with the consolidated Cisco CCNA 200-301 CCNA exam. That does not make the old material worthless. IPv4 addressing, subnetting, Ethernet switching, VLANs, routing fundamentals, troubleshooting, and basic network services remain useful networking skills. The mistake is preparing for ICND1 as though passing it can still…

The Cisco DevNet certification track is now a legacy name. On February 3, 2026, Cisco rebranded DevNet Associate, Professional, and Expert into CCNA Automation, CCNP Automation, and CCIE Automation. Active holders transitioned into the new naming, and the current certification pages now present automation as a full Cisco career family. That means a 2025 article about “the DevNet track” needs to be read historically. The skills remain important, but the career map, professional exam structure, and branding have moved forward. The 2026 Automation track is easier to explain to employers…

Cisco CCENT and the 100-105 ICND1 exam are retired. Cisco ended the CCENT credential and the split ICND1/ICND2 path on February 23, 2020, replacing them with the unified Cisco CCNA 200-301 CCNA exam. Any article announcing a “new” ICND1 course must therefore be reframed as certification history and a bridge to current CCNA study. The durable networking skills from ICND1 still matter: Ethernet, IPv4, IPv6, switching, routing basics, services, security, and troubleshooting. The certification destination changed. 100-105 ICND1 retired in 2020 Cisco’s retired-exam list records 100-105 ICND1 as retired on…

The Cisco CCNA 200-301 exam is in a transition period, but candidates preparing for the current blueprint do not need to stop. Cisco has confirmed that v1.1 is the current exam and has announced v2.0 as the next blueprint. Cisco’s own guidance is straightforward: candidates already preparing for v1.1 should continue and take the current exam rather than delay certification unnecessarily. The Cisco CCNA 200-301 study guide helps organize preparation for the current exam, while Cisco’s official topics remain the authority for scope. The skills you build now—network fundamentals, network…

CCNA candidates in late 2026 are preparing during a real exam transition. Cisco says the current Cisco CCNA 200-301 v1.1 exam remains available through February 2, 2027, and CCNA v2.0 begins February 3, 2027. That means the right study strategy depends on when you realistically expect to test. The transition also creates a resource-quality problem. Courses, books, and videos may say “current” while targeting an earlier blueprint. Date every study source and label it v1.0, v1.1, v2.0, or version-neutral so outdated material does not quietly become your main syllabus. The…
