How to approach wireless lan and wlc scenarios

Wireless questions on the CCNA cover 802.11 standards (ax/ac/n), WPA3, SSID/BSSID concepts, WLC architecture (FlexConnect, local switching), and client connectivity troubleshooting. These are mostly MCQ and multi-select.

Quick answer

Wireless security questions usually test authentication protocols (WPA2/WPA3), encryption modes, 802.11 standards and troubleshooting clients that cannot connect or associate.

WPA2 vs WPA3 authentication and encryption standards.

802.11 wireless standards, frequency bands and channel behaviour.

WLAN client troubleshooting — association, authentication and DHCP.

How SSID, authentication method and pre-shared key affect wireless access.

A network engineer is using the Cisco Meraki API to retrieve a list of SSIDs for a specific network. The API returns an HTTP 200 status but an empty array for the SSIDs. Which of the following is the most likely cause?

A
The network exists but has no SSIDs configured.
Empty array indicates no SSIDs, which is valid.
B
The network ID is incorrect.
Why wrong: Wrong network ID returns 404, not empty array.
C
The API key is invalid.
Why wrong: Invalid API key results in 401/403, not empty array.
D
The request body is malformed.
Why wrong: Malformed request returns 400, not empty array.

A Python script uses the Cisco Meraki API to create a new network and then immediately attempts to configure an SSID on that network. The SSID creation fails with a 400 error indicating 'network is not ready'. What is the most likely cause?

A
The network is not fully provisioned yet; a delay is needed.
Asynchronous provisioning requires waiting.
B
The API rate limit has been exceeded.
Why wrong: Rate limiting returns 429, not 400.
C
The API key does not have write access to networks.
Why wrong: Insufficient permissions return 403.
D
The SSID name contains invalid characters.
Why wrong: Invalid format returns a different 400 error.

A DevOps team manages a multi-site Cisco Meraki network with 50 MX appliances and 200 MR access points. They use a Python script that calls the Meraki API to collect device utilization data every hour and stores it in a CSV file. Recently, the script started failing intermittently with HTTP 429 status codes. The team suspects rate limiting but notices that the failures occur even when only one script instance runs. The script uses a single API key and makes requests to the /devices/{serial}/uplink endpoint for each MX and the /devices/{serial}/wireless/status endpoint for each MR. The script is scheduled via cron and runs sequentially. The team wants to resolve the rate limiting while minimizing changes to the script. Which course of action should the team take?

A
Introduce a delay between API calls to stay within the rate limit.
Adding a small delay reduces request rate and avoids 429 errors.
B
Distribute the API requests across multiple API keys.
Why wrong: The issue is rate limiting per key, but adding delays is simpler.
C
Switch to a webhook-based approach to receive data instead of polling.
Why wrong: Requires significant re-architecture and is not minimal.
D
Use the bulk API request feature to collect data in fewer calls.
Why wrong: Meraki does not have a bulk endpoint for these data.

A large enterprise uses Cisco Meraki for their wireless and switching infrastructure. The network team has developed a Python script that uses the Meraki API to automatically update SSID configurations across all networks. The script has been running successfully for months, performing daily updates to SSID settings such as names, passwords, and VLAN assignments. Recently, the script started failing with the following error message: '{"errors":["This operation is not allowed for this network"]}'. The team has verified the following: the API key is still valid and has access to the full organization, the network IDs used in the script are correct and the networks are active, and no changes have been made to the script code. The script uses the PUT endpoint '/networks/{networkId}/wireless/ssids/{number}' to update SSIDs. What is the most likely cause of the failure?

A
The Meraki API rate limit has been exceeded, and the request is being rejected.
Why wrong: Rate limit exceeded results in a 429 status code, not a 403 or this specific error message.
B
The network(s) have been moved to a different organization in the Meraki dashboard.
When a network is moved to another organization, the original API key loses access, causing this error.
C
The API key has been downgraded to read-only access due to a security compliance audit.
Why wrong: A read-only key would result in a 403 Forbidden error with a message like 'Insufficient privileges', not 'not allowed for this network' specifically.
D
The SSID number used in the request does not exist on the target network.
Why wrong: A non-existent SSID would cause a 404 Not Found error, not a 403 error.

An organization uses Cisco DNA Center and wants to use its Intent API to retrieve the health score of all wireless clients. Which API endpoint and method should be used?

A
PUT /dna/intent/api/v1/client-health
Why wrong: PUT is for updates, not retrieval.
B
GET /api/v1/health
Why wrong: This is not a valid DNA Center endpoint for client health.
C
GET /dna/intent/api/v1/client-health
This endpoint returns client health information.
D
POST /dna/intent/api/v1/client-detail
Why wrong: POST is not used for retrieval, and client-detail is for specific client details.

An organization wants to automate the deployment of wireless configurations across multiple Meraki networks using the Meraki Dashboard API. What authentication method should the developer use in the API requests?

A
Provide username and password in the Authorization header with Basic auth
Why wrong: Basic auth is not supported; API keys are used.
B
Use OAuth2 client credentials grant and pass a bearer token
Why wrong: Meraki does not support OAuth2; it uses API keys.
C
Include an API key in the X-Cisco-Meraki-API-Key header
Meraki API uses a static API key in the request header for authentication.
D
Generate a JSON Web Token (JWT) signed with a shared secret
Why wrong: Meraki does not use JWT; the API key is a simple string.

A large enterprise uses Cisco DNA Center to manage their campus network. They have deployed fabric technology for SD-Access. The network team wants to use the DNA Center REST API to automate the addition of new wireless users to a specific virtual network (VN) based on their location (building). They have identified the API endpoint for creating a user device in the fabric. However, when they send a POST request with the appropriate JSON body, they receive a 400 Bad Request error. The JSON payload includes the mandatory fields for hostname, MAC address, and VN name. What is the most likely cause of the error?

A
The API call requires an authentication token that is missing or expired.
Why wrong: This would result in a 401 Unauthorized error, not 400.
B
The virtual network name provided does not exist in the fabric.
If the VN doesn't exist, the API returns a 400 error.
C
The MAC address format is incorrect (e.g., lowercase vs uppercase).
Why wrong: DNA Center typically normalizes MAC formats, so this is less likely.
D
The user making the API call does not have sufficient privileges.
Why wrong: Insufficient privileges would return a 403 Forbidden error.

A large enterprise uses Cisco DNA Center to manage its campus network. The network team has automated wireless SSID provisioning using the Intent API. Recently, a new SSID was created but it does not appear on the wireless LAN controllers. The Python script that calls the API returns a 200 OK response, but the SSID is not deployed. The script uses the POST /dna/intent/api/v1/ssid endpoint with a JSON body containing the SSID name and security settings. A day later, the SSID is still missing. The engineer checks the DNA Center GUI and sees the SSID in the 'Design' section but with a 'Provisioning Failed' status. Which step should the engineer take next to resolve the issue?

A
Re-run the same API call and ignore the 200 response
Why wrong: The API call succeeded but only created the design; re-running does not provision.
B
Use the 'Provision' API endpoint to deploy the SSID to the targeted sites
A separate provision step is required to push the SSID to controllers.
C
Delete the SSID and recreate it with a different name
Why wrong: Recreating with a different name does not address the missing provision step.
D
Wait for the next scheduled provisioning cycle
Why wrong: DNA Center does not automatically provision; it requires an explicit action.

Question 10mediummultiple choice

Read the full wireless explanation →

A developer is using the Meraki Dashboard API to programmatically change the SSID name of a wireless network. The developer successfully authenticates with an API key and sends a PUT request to /networks/{networkId}/wireless/ssids/{number} with a JSON body containing the updated name. The API returns a 200 OK response, but the SSID name does not change in the Meraki Dashboard. The developer double-checks the networkId and SSID number, and they are correct. The developer also confirms that the API key has full write access to the network. What additional step is most likely required?

A
After the PUT request, send a POST request to /networks/{networkId}/wireless/ssids/{number}/provision to apply the change.
Some Meraki SSID changes require a separate provision API call to take effect.
B
Use a PATCH request instead of PUT to update the SSID.
Why wrong: PUT is the correct HTTP method for full resource update; PATCH is for partial updates.
C
Log out of the Meraki Dashboard and re-login to see the change.
Why wrong: Dashboard login does not affect API changes.
D
Regenerate the API key and try again with the new key.
Why wrong: The API key is already valid and working.

A university IT department manages a Cisco Meraki network with 200 MR access points and 50 MS switches. They use the Meraki dashboard API to automate network provisioning. A new student dormitory was added, and the team needs to create a new network and claim devices. They have a Python script that uses the Meraki API to create the network and then claim devices by serial numbers. The script successfully creates the network but fails when claiming devices with a 400 error: 'Device serial number is not valid or already claimed'. The serial numbers are correct and unused. The API key has full organization access. The script uses the endpoint 'POST /networks/{networkId}/devices/claim' with the correct body. What is the most likely cause of the failure?

A
The API key does not have permission to claim devices.
Why wrong: It has full organization access.
B
The serial numbers contain a typo.
Why wrong: They are correct.
C
The devices have not been added to the organization's inventory first.
Devices must be claimed into the organization before being assigned to a network.
D
The devices are not Meraki MR or MS models.
Why wrong: They are MR and MS.
