Learn to design enterprise networks that are resilient, secure, and ready for hybrid and cloud environments with this CCNP Enterprise course. This 300-420 ENSLD v1.1 training reflects Cisco's updated exam. It focuses on how modern enterprise networks are actually designed, covering routing and addressing strategies, high-availability campus design, SD-WAN and cloud connectivity, multicast and QoS, plus automation and telemetry concepts. Don't just memorize configurations. Practice making the kinds of design decisions engineers face when building campus and WAN networks that connect cleanly to cloud services.

What you'll learn
Design scalable enterprise routing solutions using OSPF, BGP confederations, and IPv6 strategies
Plan highly available campus networks using features like graceful restart, NSF, and NSR
Develop WAN and SD-WAN solutions for on-premises, hybrid, and cloud-connected environments
Model enterprise QoS and multicast services that support modern applications
Design automation-aware networks using YANG models and controller-based architectures
Secure campus Layer 2 networks using STP security, port security, and VACLs
How is 300-420 ENSLD v1.1 different from earlier versions?
The 300-420 ENSLD v1.1 update aligns the CCNP Enterprise exam with real-world and modern enterprise network design practices. Cisco put more emphasis on hybrid and cloud connectivity, high-availability campus design, and using automation and telemetry at scale. The updated ENSLD v1.1 exam shifts focus away from one-off designs toward networks that can evolve. This course keeps pace with those updates and teaches you how to design an enterprise network that will still make sense 5 years from now.
How much does the CCNP Enterprise and ENSLD v1.1 exam cost?
Earning CCNP Enterprise costs at least $700 and requires passing two exams: the core 350-401 ENCOR exam ($400) and one of eight concentration exams like 300-420 ENSLD v1.1 ($300). Given that investment, a structured course is a good idea. It helps you do more than prepare for the test: it sharpens your design thinking and builds your confidence to defend real-world network decisions.
How much experience should you have before taking ENSLD?
ENSLD works best if you already have several years of hands-on networking experience (about 5-10 years in enterprise environments). You don't need to be an architect yet, but you should be comfortable with routing, campus networks, and WANs. If you're starting to get pulled into design discussions or asked why something should be built a certain way, ENSLD is a strong next step.
How hard is the 300-420 ENSLD v1.1 exam?
ENSLD is challenging in a different way than some of Cisco's configuration-heavy exams. It tests your ability to evaluate tradeoffs, spot design risks, and choose the right approach, not just remember commands. It's the kind of exam that separates maintainers and engineers from designers and architects, so it's perfect if you want to show off your judgment and experience.
Is 300-420 ENSLD and CCNP Enterprise worth it?
If you want to move from roles like Senior Engineer and become someone trusted with design decisions, ENSLD is absolutely worth it. It helps you think beyond individual devices and focus on systems that scale, survive failures, and adapt over time. Earning the CCNP Enterprise along with ENSLD shows you don't just build networks, you design enterprise networks that will hold up under real business demands for years to come.
Who is this training for?
This course is for experienced network engineers who want to move from implementation, maintenance, and management into design-focused roles. It's ideal if you've spent 5-10 years working with enterprise routing, campus, and WAN networks and now want to confidently design solutions that span the entire end-to-end network.
