Cisco (WLSD) 300-110 Real Exam Dumps [July 2026 Update]

The 300-110 WLSD exam was relaunched on March 19, 2026, as part of Cisco’s new standalone CCNP Wireless certification track, and it brought a change that most preparation resources have not caught up to: Wired and Wireless Infrastructure is now the single heaviest exam domain at 30%, not Site Survey. Wireless engineers instinctively spend the most time on site survey preparation because it feels like the most specialized and “wireless-specific” topic. But the infrastructure domain, covering WLC architecture, RRM design, PoE planning, FlexConnect versus Central Switching decisions, licensing models, high-density environment design, and Catalyst Center AI-Enhanced RRM, constitutes nearly a third of your total score. Candidates who know every detail of Ekahau but cannot confidently choose between a centralized, FlexConnect, and Embedded Wireless Controller architecture for a given enterprise scenario consistently lose points where the exam allocates most of them.

The 300-110 WLSD (Designing Cisco Wireless Networks v1.2) is the design concentration exam for the new Cisco CCNP Wireless certification, which in 2026 became an independent track, completely separated from CCNP Enterprise. CCNP Wireless now requires passing the WLCOR core exam plus either WLSD (design concentration) or WLSI (implementation concentration). WLSD validates the planning and design skills required to build enterprise wireless networks: gathering requirements, selecting AP types and antenna configurations, conducting site surveys, designing infrastructure, planning mobility groups, and engineering high availability. It is the credential for wireless network designers, RF engineers, and enterprise WLAN architects.

Cert Empire’s 300-110 WLSD exam questions are built against the confirmed v1.2 exam blueprint with domain-proportional coverage: more questions on Infrastructure and Mobility design than on Site Survey, exactly as the actual exam distributes its points.

Exam Snapshot

What the WLSD Exam Tests: Domain by Domain with Weights

1. Wireless Site Survey (25%)

Site survey is tested at the design-decision level, not as a technician walkthrough. The exam tests:

Design Requirement Collection: Understanding client density requirements (how many devices per AP is reasonable for data-only versus voice versus video environments), evaluating real-time application constraints (latency budgets for voice, multicast requirements for video), selecting AP types and antenna patterns for specific deployment environments (directional antennas for long-corridor deployments, omnidirectional for open floor plans), and defining deployment types: data, location-based, voice, and video.

Material Attenuation: How building materials affect RF propagation. Concrete and rebar attenuate 10-15+ dB per wall; glass attenuates 3-5 dB; drywall attenuates 3-5 dB. The exam presents building construction scenarios and asks which survey methodology and AP count is appropriate.

Survey Methodologies: The three survey types are tested specifically:

• Predictive survey: Software-based (Ekahau AI Pro, iBwave) using building floor plans to predict RF coverage without physical APs. Used early in design to estimate AP count and placement.
• Pre-deployment (validation) survey: Conducted with APs physically placed and transmitting before final installation to validate the predictive design.
• Post-deployment (verification) survey: Conducted after final installation to confirm actual coverage matches design requirements.

The sequence and purpose of each survey type is an exam-tested distinction. Candidates who confuse predictive with validation surveys lose points on sequencing questions.

2. Wired and Wireless Infrastructure (30%) — Highest Domain Weight

Power over Ethernet (PoE) Design: Cisco access points require PoE or PoE+ depending on the model. The exam tests power budgets: how many APs can a switch support based on its total PoE budget, what happens when the budget is exceeded, and which AP models require PoE+ versus standard PoE. Cabling requirements (Cat5e minimum for 1Gb, Cat6a for full PoE+ capacity) and mounting/grounding procedures are also covered.

WLC Architecture and Licensing: The three primary controller architectures the exam tests:

• Centralized (WLC-based): All APs tunnel traffic back to a central WLC. Best for campuses where the controller is on-premises with sufficient bandwidth back-haul.
• FlexConnect (formerly HREAP): APs locally switch traffic without tunneling to the WLC. Best for branch offices where WAN bandwidth is limited. The exam tests Central vs. Local switching modes within FlexConnect, split tunneling, and VLAN mapping.
• Embedded Wireless Controller (EWC): Controller embedded within an AP. Best for small branch deployments. The exam tests when EWC is appropriate and its architectural limitations compared to dedicated WLC.

Radio Resource Management (RRM) Design: Cisco’s RRM automates channel and power selection. The exam tests: what RRM does automatically (channel assignment, transmit power control, coverage hole detection), what requires manual override (high-density environments where automatic adjustments cause instability), and what Catalyst Center AI-Enhanced RRM adds (predictive analytics and proactive adjustments using Cisco AI). The RxSOP (Receiver Start of Packet) threshold is a specific tuning parameter the exam tests: increasing RxSOP makes APs less sensitive to low-power clients, effectively reducing cell size in high-density environments.

High-Density Wireless Design: Stadiums, auditoriums, conference halls, and manufacturing environments with thousands of devices require specific design approaches: reduced AP cell sizes (lower transmit power), directional antennas to minimize co-channel interference, 5 GHz-only designs where possible, and client load balancing policies.

Location Services Design (Cisco Spaces integration): How to design for location accuracy including AP placement requirements for location (minimum three AP coverage), understanding location triangulation versus fingerprinting, and how Cisco Spaces integrates with the wireless infrastructure for real-time location tracking.

Wireless Bridging (Mesh): Outdoor campus and campus bridging scenarios. Mesh AP operation modes (RAP, MAP), Ethernet bridging for connecting wired segments via wireless backhaul, and workgroup bridges (WGB) for connecting wired devices to a wireless network.

3. Mobility (25%)

Mobility Groups and Domains: A mobility group is a cluster of WLCs that share client state information to enable seamless roaming. The exam tests how to design mobility groups for campus, WAN, and inter-DC roaming scenarios: how large a mobility group can be, what the performance impact of mobility tunneling across WAN links is, and when to use anchor controllers for guest traffic.

Data and Control Plane Tunneling: Mobility tunneling uses CAPWAP data and control channels. The exam tests the difference between intra-controller roaming (client moves between APs on the same WLC, no mobility tunnel), inter-controller roaming within the same mobility group (mobility tunnel established), and inter-mobility-domain roaming (anchor/foreign controller relationship required).

Site Tags and Profiles: In the Catalyst 9800 controller architecture, site tags associate APs with AP join profiles, Flex profiles, and policy profiles. The exam tests how to design a site tag structure that correctly applies the right configurations to APs in different deployment locations.

Optimizing Roaming for Real-Time Applications: VoWLAN and video streaming require fast roaming (sub-50ms handoff). The exam tests 802.11r Fast BSS Transition, 802.11k Neighbor Reports, and 802.11v BSS Transition Management as design tools for accelerating client roaming in real-time application environments.

4. WLAN High Availability (20%)

Stateful Switchover (SSO): Two WLCs in an active/standby pair where the standby maintains a synchronized client database. When the active WLC fails, the standby takes over without client re-association. The exam tests the requirements for SSO (same hardware model, same IOS-XE version, dedicated HA port), the failover time, and when clients notice the switchover.

AP Failover: Primary, Secondary, Tertiary Controllers: Each AP can be configured with up to three WLC preferences. The exam tests how to design AP controller assignments to ensure no single controller failure strands APs, and how to configure AP priority within a controller (high-priority APs reconnect first after failover to ensure critical coverage areas come back quickly).

Link Aggregation (LAG): Bundling multiple uplinks from the WLC to the upstream switch for bandwidth and redundancy. The exam tests LAG configuration requirements and what happens to APs if a LAG member link fails.

Anchor Controller Strategies: Using an anchor controller in the DMZ to terminate guest wireless traffic before it enters the corporate network. The exam tests how to design the anchor-foreign controller relationship, what traffic flows through the mobility tunnel, and how to ensure guest traffic is securely isolated.

What to Expect on Exam Day

• 120 minutes, multiple-choice and scenario-based questions.
• Design decision questions: given an enterprise wireless requirement (client density, application type, building construction, budget), which design choice is correct?
• Ekahau and spectrum analyzer tool knowledge is expected at the planning level, not the click-by-click tool use level.
• Cisco Catalyst 9800 controller architecture and IOS-XE platform context throughout, not legacy WLC.

5 Study Tips for Cisco 300-110 WLSD

• Tip 1: Allocate 30% of your study time to Wired and Wireless Infrastructure. It is the highest-weighted domain. FlexConnect architecture decision-making, PoE budget design, and RRM tuning in high-density environments are where exam points concentrate.
• Tip 2: Learn all three site survey types by purpose and sequence: predictive (design phase), pre-deployment validation (before final install), post-deployment verification (after final install). The exam tests which is appropriate when and what each confirms.
• Tip 3: Study SSO in detail including its hardware requirements, failover mechanics, and what clients experience during switchover. High Availability at 20% means HA questions appear regularly, and SSO is the most tested HA mechanism.
• Tip 4: Understand the anchor-foreign controller design for guest wireless. This architecture appears in mobility scenarios and high availability scenarios and is one of the most scenario-tested topics on the exam.
• Tip 5: Practice with Cert Empire’s 300-110 WLSD exam questions with domain weighting proportional to the actual blueprint so your practice experience matches the real exam distribution.

Readiness Check

1. An enterprise customer is deploying a wireless network in a multi-story hospital building. Client density is approximately 15 voice-capable devices per 1,000 sq ft, with strict latency requirements for VoWLAN. Building construction is concrete and rebar throughout. Which wireless architecture is most appropriate (centralized, FlexConnect, or EWC), what AP antenna type and mounting strategy addresses the concrete attenuation, and which 802.11 feature set is required to achieve sub-50ms roaming handoff for voice clients?
2. A wireless designer is planning a 120-AP deployment across a campus and needs to estimate AP count and placement before any physical APs are installed. Which survey methodology is appropriate at this stage? After the design is complete and APs are physically placed but not yet in their final ceiling mounting positions, which survey type confirms the design is valid? After final installation, which survey type confirms the live network meets coverage requirements?
3. A stadium wireless deployment for 35,000 concurrent users needs to minimize co-channel interference while maximizing per-user throughput. What specific RRM tuning parameter reduces AP cell sizes by making APs less sensitive to distant low-power clients, and what is the design trade-off of increasing this value aggressively in a dense environment?
4. A campus WLC pair is deployed in SSO configuration. The active WLC loses power completely. What happens to currently connected wireless clients within 1 second, within 5 seconds, and within 30 seconds of the failure? What is the hardware requirement that must be met for SSO to function, and how does this differ from standard N+1 controller redundancy?
5. A company wants guest wireless at their headquarters to be completely isolated from the corporate network, with guest traffic exiting directly to the internet through a DMZ firewall. The guest WLAN is served by access point that also carry corporate SSIDs. Describe the anchor-foreign controller design required, what traffic travels through the mobility tunnel, and where the anchor controller must be physically placed relative to the corporate firewall.

FAQS

What is the Cisco 300-110 WLSD exam?

The Cisco 300-110 WLSD (Designing Cisco Wireless Networks v1.2) is the design concentration exam for the Cisco CCNP Wireless certification, relaunched as an independent wireless track in March 2026. It validates expertise in wireless network design including site surveys, wired and wireless infrastructure, mobility, and WLAN high availability.

How is the 300-110 WLSD different from ENWLSD?

The 300-110 WLSD is the successor to the former ENWLSD exam that was part of CCNP Enterprise. The content is similar but the 300-110 is now part of the independent CCNP Wireless track. Starting in 2026, CCNP Enterprise no longer includes wireless content. Candidates who passed ENWLSD before March 19, 2026 have their results recognized within the 3-year validity period.

What is the highest-weighted domain on the WLSD exam?

Wired and Wireless Infrastructure is the highest-weighted domain at 30%. It covers WLC architecture decisions (centralized, FlexConnect, EWC), PoE planning, RRM design including AI-Enhanced RRM, high-density environments, location services, and wireless bridging/mesh.

How long is the 300-110 WLSD exam?

The exam is 120 minutes. This provides adequate time for scenario-based design questions that require reading enterprise requirements before selecting the appropriate design approach.

What is the difference between SSO and N+1 controller redundancy?

SSO (Stateful Switchover) requires two identical WLC models connected via a dedicated HA port, with the standby maintaining a synchronized client state database. Failover is near-instant and clients do not re-associate. N+1 redundancy uses a spare controller that APs fail over to, but clients must re-associate after failover.
