AI-900 is retired. Microsoft ended the Azure AI Fundamentals exam on June 30, 2026, and the current fundamentals exam is AI-901. That transition matters because AI-901 is not simply AI-900 with a new code. The current exam still expects candidates to recognize core AI workloads and responsible-AI principles, but it also raises the practical baseline. Microsoft’s April 15, 2026 skills outline expects foundational technical ability, familiarity with Azure resources, Python syntax, and awareness of how APIs, SDKs, and command-line tools fit into simple AI solutions. Anyone using an old AI-900…

The AZ-800 exam is retired, but its hybrid-core content remains highly relevant to the current AZ-802 Administering Windows Server exam. Candidates who already built a study plan around AZ-800 should map that work into the consolidated AZ-802 blueprint instead of discarding it. The new exam still expects AD DS, hybrid management, virtualization, networking, storage, security, and troubleshooting. The transition also simplifies certification planning. The former Windows Server Hybrid Administrator Associate path required AZ-800 and AZ-801; the current Microsoft page now centers the credential on AZ-802. That means the preparation question…

PL-200 retired on August 31, 2026, but two of its most useful skill areas—Power Automate and environment management—remain central to current Power Platform work. New candidates should prepare for AB-410 rather than the retired Functional Consultant exam, while reusing the operating discipline that made reliable automation and controlled environments important in the first place. Model the process before building the flow Start with event, state, actor, decision, action, exception, and completion. A flow is easier to design when the business process is explicit. If a request can be approved, rejected,…

NSE7_NST-7.2 belongs to an older Fortinet certification era. Fortinet changed its program again on July 15, 2026, retiring the FCP, FCSS, and FCX labels and returning to an NSE 1–8 structure. That means an article telling candidates how to “ace NSE7 NST 7.2” as a current exam would now be misleading. The durable value of the old material is its subject matter: advanced network security, FortiGate behavior, troubleshooting, enterprise architecture, and operational judgment. Candidates searching for the retired name now need to understand the current Fortinet certification structure and the…

Data engineering has become a critical area in modern technology environments because organizations depend on reliable data systems for decision-making, automation, and digital operations. A professional data engineer works with large volumes of information and develops solutions that allow businesses to collect, process, store, and analyze data efficiently. The role requires knowledge of data platforms, cloud services, security practices, and system performance methods. A data engineer on Google Cloud focuses on building dependable data solutions that support different business needs. These professionals manage data pipelines, design storage approaches, maintain data…

AWS certifications are professional credentials that validate expertise in using Amazon Web Services (AWS). These certifications help to demonstrate proficiency in cloud technologies and can significantly boost career opportunities in data and cloud computing. The certifications offered by AWS are recognized globally and have become a standard in the tech industry for professionals working with cloud computing and data engineering. AWS certifications are structured across four different levels to accommodate various experience levels, from beginners to experts. Understanding the different certification levels and their relevance to data engineers is crucial…

AWS Certified Data Engineer – Associate remains a current associate-level certification, and the DEA-C01 exam validates the practical work of building data pipelines, choosing and managing data stores, operating data systems, and applying security and governance. The current exam guide uses version 1.1, published in December 2025, with the same four core domains used in 2026. The credential is most useful for professionals who work with data ingestion, transformation, orchestration, storage, data quality, operational support, and secure access inside AWS. It is not a general analytics certificate; it is an…

AZ-400 is an advanced DevOps exam, not a general introduction to Agile or cloud development. Microsoft expects candidates to design and implement the systems that move work from an idea to production: collaboration and traceability, source control, build and release pipelines, security and compliance, and instrumentation. The exam assumes you can connect people, process, Git, automation, Azure, GitHub, and Azure DevOps into one delivery system. The English AZ-400 exam was updated on July 27, 2026 and currently has no listed retirement date. The weighting is unusually clear about where to…

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…

The Cisco 200-201 exam, officially titled Understanding Cisco Cybersecurity Operations Fundamentals, is the qualifying exam for the Cisco Certified CyberOps Associate certification. It is designed to assess whether a candidate has the foundational knowledge needed to work in a security operations center environment. The exam covers a broad range of topics including security concepts, security monitoring, host-based analysis, network intrusion analysis, and security policies and procedures. Each domain carries a different weight, and knowing which areas demand the most attention helps you allocate your study time more effectively. Many candidates…

Amazon AWS SCS-C02 is no longer the current Security – Specialty blueprint. In 2026 AWS introduced SCS-C03, so candidates should not build a new study plan around the older SCS-C02 domain structure. The useful approach is to preserve the security knowledge that transfers, identify what the current exam emphasizes, and use the SCS-C03 guide as the source of truth for preparation. What changed with Amazon AWS SCS-C03 The current SCS-C03 blueprint organizes the exam into six domains: Detection at 16%, Incident Response at 14%, Infrastructure Security at 18%, Identity and…
