Cisco ENWLSD 300-425 study guide
Cisco ENWLSD 300-425 · Work through your exam, one topic at a time.
The Cisco 300-425 ENWLSD exam, part of the CCNP Enterprise concentration track under the Designing Cisco Wireless Enterprise Networks title, tests whether you can plan an enterprise wireless deployment rather than just operate one. It suits network engineers, wireless consultants, and pre-sales or design engineers who already understand controller-based Wi-Fi and now need to prove they can gather requirements, size infrastructure, and defend design choices. The Cisco ENWLSD 300-425 study guide has 7 sections and about 2,992 words.
01Gather information from the existing network
This domain asks you to prove you can discover the current network, the physical environment, and the business requirements before designing anything. The exam favors candidates who can turn raw discovery data into design constraints, not candidates who jump to an AP count.
458 words, about 2 min02Design the wireless network infrastructure
This domain tests the core RF and network-services design: AP placement, antennas, controller sizing, PoE, DHCP/DNS, multicast/mDNS, QoS, IPv6, and mesh/outdoor considerations. The exam expects you to justify a design with numbers.
488 words, about 2 min03Design the wireless network for high availability
This domain tests redundancy at the controller, AP, power, and software levels. You must know the difference between N+1, N+N, and stateful SSO, and when each is appropriate.
434 words, about 2 min04Design the wireless network for mobility
This domain tests roaming design: mobility groups, mobility lists, inter-controller and inter-subnet roaming, and anchor/foreign tunnels. The key skill is choosing the simplest mobility model that preserves client IP addresses without stretching latency.
432 words, about 2 min05Design the wireless network for guest access
This domain tests guest SSID design, DMZ anchoring, web authentication, firewall policy, and guest traffic isolation. The design goal is simple: guests get internet access and nothing else, and guest traffic never touches the corporate core.
414 words, about 2 min06Design the wireless network for location services
This domain tests location-ready RF design, location platform sizing, and the difference between coverage-grade and location-grade AP density. Location accuracy is an RF design outcome, not a software setting.
409 words, about 2 min07Design the wireless network for security
This domain tests WLAN security policy selection, AAA integration, rogue detection, management-plane hardening, and segmentation. The exam wants designs that map a client type to an authentication method and an enforcement point.
