Policy-based routing is a network traffic management technique that allows network administrators to make forwarding decisions based on criteria beyond the destination IP address that traditional routing protocols use exclusively. In conventional routing, a router examines the destination address of each incoming packet and consults its routing table to determine the appropriate next hop, applying […]
The world of enterprise networking has long been dominated by a handful of powerful names, but few rivalries have sparked as much debate in recent years as the one between Ubiquiti and Cisco. On one side stands Cisco, a decades-old titan whose name has become almost synonymous with enterprise-grade networking infrastructure. On the other side […]
Legacy exam context: The former CCNA Routing and Switching credential and the old two-exam pathway were retired when Cisco consolidated its associate networking certifications. The active CCNA pathway uses the 200-301 exam; the routing, switching, addressing and troubleshooting skills remain central, but a candidate must not schedule a retired CCNA R&S examination. The Cisco Certified […]
The Cisco Certified Network Professional certification stands as one of the most respected and widely recognized credentials in the global networking industry, validating the advanced technical knowledge and practical skills that professional-level network engineers need to design, implement, and troubleshoot complex enterprise network infrastructures. Earning the CCNP places a networking professional firmly in the category […]
The old CCNA CyberOps naming has been superseded by CCNA Cybersecurity. Cisco’s current associate exam is 200-201 CCNACBR, covering security concepts, monitoring, host-based analysis, network intrusion analysis, and policy and procedures. CCNP Security is a professional track with its own current core and concentration exams; do not use retired CBROPS labels or prerequisites as present-day […]
Cisco regularly retires or renames examinations as technology and its certification structure change. The headline of this legacy article refers to ‘nine’ retirements, but a candidate in October 2026 should not interpret that old headline as a newly announced list of nine exams. Cisco’s official retired-exams database gives a date and applicable successor for each […]
Cisco DevNet helped normalize a change in network engineering: infrastructure became something professionals increasingly managed through software, APIs, version control, and repeatable automation rather than commands typed on individual devices. Its original certification names made sense when networking and application development were commonly treated as separate disciplines. The skills it helped popularize are still valuable, […]
Cisco’s original CCNA Cyber Ops certification was retired during the company’s 2020 certification restructuring. Its successor was called CyberOps Associate for a period, and the active associate-level security operations credential is now named Cisco Cybersecurity Associate, using the 200-201 CBROPS exam family. These names belong to related stages of the program, not three simultaneously available […]
YANG emerged in 2010 as a specialised data modelling language, originally defined to describe data sent over the NETCONF network management protocol. It provides a standardised framework for defining how network devices are configured and managed, enabling the detailed specification of network devices’ configuration, operational data, and policies in a structured, modular, and extensible manner. […]
Network automation is the practice of using software, scripts, and programmatic tools to configure, manage, monitor, and operate network infrastructure without relying on manual, command-line-driven processes for every change. In traditional network operations, an engineer would log into each device individually, type configuration commands, verify the results, and move to the next device. This approach […]
The networking industry is experiencing one of the most profound transformations in its history, moving decisively away from manual, command-line-driven configuration toward programmable, software-defined infrastructure that can be managed, monitored, and modified through code. Cisco has positioned itself at the forefront of this transformation through its DevNet program, a comprehensive ecosystem of tools, platforms, certifications, […]
Why Cisco CCNA Feels Difficult—and How to Prepare CCNA difficulty depends on what networking you already know The Cisco CCNA 200-301 exam can feel demanding because it covers several networking domains that interact in real support work. A candidate might understand subnetting but struggle to interpret a routing table, or know an ACL definition but […]
Current product-name note: Cisco renamed DNA Center to Cisco Catalyst Center. The original published title and permalink are retained here; the management, assurance, policy and automation functions described below refer to the product family now documented as Catalyst Center. Specific features and licenses remain release- and device-dependent, so administrators should consult current Cisco documentation before […]
The decision between pursuing the Cisco ENCOR exam and the Cisco ENSLD exam first is one that many networking professionals find genuinely confusing, primarily because the relationship between these two credentials is not immediately obvious from their names or surface-level descriptions. Both exams sit within the Cisco enterprise networking certification pathway, both require serious preparation […]
The Cisco Certified Network Professional certification represents a significant step forward for anyone pursuing a serious career in networking. Unlike entry-level credentials, the CCNP demands a deeper level of practical knowledge, requiring candidates to work through complex configurations, troubleshoot multi-layered network problems, and demonstrate real competence across a range of technologies. A well-designed lab environment […]
