How many questions are on the 350-101 WLCOR exam? Cisco does not publish a number. What Cisco does publish is enough to plan around: a 120-minute exam, US$400, offered in English and Japanese, with seven weighted topic areas that decide where your study hours should go.
That gap between the question people search for and the facts Cisco actually prints is the reason for this post. Below you will find the official facts, an honest note on the question-count estimates you will see elsewhere, the seven domains with their weights, a six-week plan, a worked troubleshooting scenario, and the mistakes that tend to cost wireless engineers points. Every exam fact was checked on Cisco's own pages on 12 November 2026.
What is the 350-101 WLCOR exam?
WLCOR stands for Implementing and Operating Cisco Wireless Core Technologies. It is the core exam of Cisco's wireless track: pass it and you earn the Cisco Certified Specialist - Wireless Core badge, and the same pass counts as the core exam for both CCNP Wireless and CCIE Wireless.
The official Cisco 350-101 WLCOR exam page lists the facts below. Keep them next to your plan, because they are the only numbers that come straight from Cisco:
- Exam time: 120 minutes.
- Cost: US$400, or Cisco Learning Credits.
- Languages: English and Japanese.
- Certification earned: Cisco Certified Specialist - Wireless Core.
- Counts toward: CCNP Wireless and CCIE Wireless, as the core exam.
- Scope in Cisco's words: radio frequency fundamentals, 802.11 technology fundamentals, client connectivity, wireless monitoring and management, automation and AI.
The blueprint is version 1.0. That matters when you pick study material: anything written for the older wireless concentration exams covers some of the same ground, but it will not cover the Automation and AI domain or the newer 802.11 topics such as Multi-Link Operation (MLO).
How many questions are on the 350-101 WLCOR exam, and what score passes?
Cisco does not state a question count or a passing score for WLCOR, on the exam page or in the exam topics document. Cisco sets the bar for each exam form with scaled scoring, so no single official cut score exists.
You will still see figures quoted. NWExam's syllabus page, for example, gives an estimate of 90 to 110 questions and a scaled pass mark of roughly 750 to 850 out of 1000. Treat numbers like these as planning estimates, not as Cisco facts. They are useful for one thing: pacing. If you assume around 100 questions in 120 minutes, you have a little over one minute per question, which tells you two things straight away:
- You cannot afford to work every RF calculation from first principles. The common conversions must be automatic.
- You need time left over for the longer configuration and troubleshooting items, which take more reading than a one-line definition question.
What do the seven WLCOR domains weigh?
The weights come from Cisco's 350-101 WLCOR v1.0 exam topics document. Read them as a budget for your study hours:
- RF Fundamentals, 15%: how radio waves propagate, RSSI, transmit power and receive sensitivity, interference, noise and rogue APs, SNR, RF mathematics and antenna characteristics.
- 802.11 Technology Fundamentals, 10%: regulatory bodies, IEEE 802.11 and the Wi-Fi Alliance, usable channel and power combinations, regional EIRP limits, frequency bands, RRM basics, modulation, channel width, MIMO, MU-MIMO and MLO, topologies and frame types.
- Wireless Network Implementation, 10%: Cisco wireless architectures (fabric, mesh, local and cloud), the physical connections, and management access to APs, WLCs and the dashboard.
- Wireless Network Operation, 20%: initial setup, AP discovery and join, AP modes, WLAN access, and client policies across the WLC, Dashboard, Catalyst Center, ISE, Spaces and mobile device management.
- Client Connectivity Configuration, 20%: authentication outside and on the controller, client settings on different operating systems, roaming and guest networking.
- Wireless Monitoring and Management, 15%: maintenance, client monitoring, troubleshooting client connectivity and platform integrations.
- Automation and AI, 10%: reading Python, NETCONF/YANG, wireless infrastructure APIs, AI Analytics and AI Operations in Catalyst Center, and AI-RRM.
Add up domains 4, 5 and 6 and you get 55%. More than half of the exam is about running a wireless network day to day: joining APs, connecting clients securely, and finding out why a client is unhappy. The theory domains (1 and 2) are 25% together, and they feed every hands-on question anyway, because you cannot troubleshoot a roaming problem without understanding signal strength and channel planning.
Where does WLCOR fit in CCNP Wireless and CCIE Wireless?
WLCOR plays the same role for wireless that the other 350-series core exams play for their tracks. One pass does three jobs:
- It earns the Specialist - Wireless Core badge on its own.
- It is the core half of CCNP Wireless. You still add a concentration exam to complete the professional certification; check Cisco's current list of wireless concentration exams before you plan the second step.
- It is the written qualifier for CCIE Wireless, which then requires the lab exam.
That last point shapes how deep to go. Even if CCNP is your goal, the core exam is written to the level a future CCIE candidate needs, so expect questions that ask why, not only what.
How should you study for WLCOR in six weeks?
Six weeks suits an engineer who already works with Cisco wireless. If you are coming from routing and switching only, stretch each week to ten days. The plan follows the domain weights:
- Week 1, RF and math (domain 1): learn the dB rules until they are reflex. 0 dBm is 1 mW, 20 dBm is 100 mW, plus 3 dB roughly doubles power and plus 10 dB multiplies it by ten. Practise EIRP as transmit power minus cable loss plus antenna gain. Compare SNR readings on your own laptop at different distances from an AP.
- Week 2, 802.11 and regulation (domain 2): channel widths, bands, modulation and how MIMO, MU-MIMO and MLO differ. Learn why regional EIRP limits change which channel and power pairs are legal. Read a few frame captures and name the management, control and data frames.
- Week 3, architectures and AP join (domains 3 and 4): draw local, mesh, fabric and cloud deployments from memory. Walk an AP through discovery and join on a Catalyst 9800 controller, lab or virtual, and change AP modes to see what each one does.
- Week 4, client access and security (domain 5): build a PSK WLAN, then an 802.1X WLAN against a RADIUS server such as ISE, then a guest WLAN. Connect a Windows, a macOS and a phone client to each and note what differs. Study how roaming works and what makes it fast or slow.
- Week 5, monitoring and troubleshooting (domain 6): break things on purpose. Wrong shared secret, wrong VLAN, expired certificate, AP on the wrong controller. For each break, find it from the client monitoring views and the controller logs before you look at your notes.
- Week 6, automation, AI and review (domain 7 and all): read short Python scripts that call a controller or Catalyst Center API and say what they return. Learn what NETCONF/YANG model data looks like. Read up on AI Analytics, AI Operations and AI-RRM in Catalyst Center. Finish with timed mixed review across all seven domains.
Cisco's own Cisco U. learning path for Implementing and Operating Cisco Wireless Core Technologies is the official course that matches this blueprint. Use it as the spine of the plan and your lab as the muscle.
What does a WLCOR troubleshooting scenario look like?
Here is a scenario written for this post, not taken from any exam, to show the kind of thinking domains 5 and 6 reward.
A hospital adds a new 802.1X WLAN. Laptops on the old WLAN work. On the new one, every client sees the SSID, tries to connect, and fails after a few seconds. APs are joined and serving other WLANs normally.
Work it in layers rather than guessing:
- RF first, briefly. The SSID is visible and other WLANs work on the same APs, so coverage and AP join are not the problem. Move on.
- Association versus authentication. Clients reach the point of trying to authenticate, so association is fine. The failure sits in the 802.1X exchange.
- Controller to RADIUS. Check that the controller can reach the RADIUS server and that the shared secret matches on both sides. A mismatched secret shows up as dropped or rejected requests on the server.
- The server's view. The RADIUS server logs, such as ISE live logs, will say whether requests arrive and why they fail: unknown network device, wrong policy, or a certificate the client does not trust.
- The client's view. If the server presents a certificate the clients were never told to trust, every client fails the same way, which matches the symptom here.
The lesson for the exam is the order, not the answer. Questions in these domains often hide the cause in one detail of a long description, and a fixed checking order stops you jumping at the first familiar word.
Which mistakes cost WLCOR candidates the most?
These are the patterns that hurt experienced wireless engineers most often:
- Studying only the controller. Domain 4 names the WLC, Dashboard, Catalyst Center, ISE, Spaces and mobile device management. If you only know one platform, a policy question set on another will feel foreign.
- Skipping RF math. It is 15% on its own and appears inside other questions too. Slow arithmetic eats the minutes you need for long items.
- Ignoring Automation and AI. At 10% it is worth as much as all of 802.11 fundamentals. You do not need to write code, but you do need to read it.
- Treating MLO and AI-RRM as buzzwords. They are named topics in v1.0, so know what each one changes in a real network.
- Using old wireless study guides unchecked. Earlier exams covered overlapping ground, but the blueprint changed. Map every chapter you read back to a line in the v1.0 topics.
How do you know you are ready to book WLCOR?
Book when you can do three things without notes: convert dBm and mW and work out EIRP in your head, walk an AP from power-on to joined, and diagnose a failed 802.1X client from the server logs. If any of the three still needs a reference, give that domain another week.
A timed run is the best final check, because pacing is where unprepared candidates lose marks. A 350-101 WLCOR timed practice exam set to the full 120 minutes shows you whether your one-minute-per-question rhythm holds up across all seven domains.
On the day itself, read the final sentence of every long scenario first. It tells you whether the question wants a cause, a fix or a command, and that saves you from reading a long network description twice.
If your path also runs through security, the Cisco 300-220 post on this blog, a threat-hunting study guide for CBRTHD, uses the same plan-by-weight approach for a CCNP Cybersecurity concentration exam.
Is there a video on preparing for a Cisco core exam?
NWExam's channel has no WLCOR video yet. The closest is its guide to another 350-series core exam, ENCOR 350-401, which walks through the same format questions this post covers: how a core exam is built, how to read its domains and how to plan your weeks.
