Exam 350-401 topic 1 question 228 discussion

Sensor mode: this is a special mode which is not listed in the books but you need to know. In this mode, the device can actually function much like a WLAN client would associating and identifying client connectivity issues within the network in real time without requiring an IT or technician to be on site.

Client mode allows the AP to act as a WLAN client for another AP. Sensor mode does the same; in addition, it enables the AP to act as a dedicated sensor to run client tests such as Network Client Connection On-Boarding Tests, General Network Tests, and Client Application Tests.

C is correct Using a supported AP or dedicated sensor the device can actually function much like a WLAN client would associating and identifying client connectivity issues within the network in real time without requiring an IT or technician to be on site. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-6/b_Cisco_Aironet_Sensor_Deployment_Guide.html#:~:text=Using%20a%20supported%20AP%20or%20dedicated%20sensor%20the%20device%20can%20actually%20function%20much%20like%20a%20WLAN%20client%20would%20associating%20and%20identifying%20client%20connectivity%20issues%20within%20the%20network%20in%20real%20time%20without%20requiring%20an%20IT%20or%20technician%20to%20be%20on%20site.

if the question specifically asks about an AP mode that allows an AP to function like a WLAN client, "sensor mode" wouldn't be the most direct answer, as it's primarily focused on security monitoring rather than client behavior emulation. So, while sensor mode can indirectly assist in identifying client connectivity issues, it's not the mode primarily intended for that purpose. Therefore, the most direct answer to the question would still be "client mode" (Option A) as In client mode, the AP behaves like a wireless client, allowing it to associate with another AP as if it were a wireless device. This mode is often used for wireless site surveys or troubleshooting to assess the performance of a WLAN from the perspective of a client device.

its C check the cisco site.. Introduction to Sensor Mode As these wireless networks grow especially in remote facilities where IT professionals may not always be on site, it becomes even more important to be able to quickly identify and resolve potential connectivity issues ideally before the users complain or notice connectivity degradation. To address these issues, Cisco introduced a Wireless Service Assurance and a new AP mode called sensor mode. For more information, see Cisco Aironet Sensor Deployment Guide. https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/config-guide/b_wl_16_10_cg/b_wl_16_10_cg_chapter_01101110.html

So which one is it? I don't think it is sensor mode because that isn't even a mode on the AP. And this is directly from the posted resources that people are so confidently posting, wondering if people even read the source they are posting: The sensor is not an AP. It’s designed as a dedicated sensor, simulating wireless client behavior. The sensor does not join the wireless controller because it operates independently from the wireless controller. Instead, the sensor depends on Cisco DNA Center for provisioning, configuration, operation, monitoring, and upgrade. https://www.cisco.com/c/dam/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/deploy-guide/Cisco_1800S_Sensor_Deployment_Guide_133.pdf

The AP mode that allows a supported AP to function like a WLAN client would, associating and identifying client connectivity issues is "client mode" (option A). In client mode, the AP acts as a client to connect to another WLAN network and can identify connectivity issues from a client's perspective. Option B, "SE-connect mode" is not a commonly used AP mode, and there is no standard definition for it. Option C, "sensor mode," is a mode in which the AP monitors the wireless spectrum for intrusion detection and prevention purposes. Option D, "sniffer mode," is a mode in which the AP captures and analyzes network traffic for troubleshooting and diagnostic purposes.

The answer is 100% C Here's Cisco's Whitepaper where it clearly states it: https://www.cisco.com/c/dam/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/deploy-guide/Cisco_1800S_Sensor_Deployment_Guide_133.pdf

Answer is C - you can even buy a dedicate module which would act as a client. C is the answer.

client mode for sure !

Answer is Sniffer mode - D.

No such mode as sensor mode now, must be sniffer mode

D, Sniffer Mode. Because these questions are based on the new Wireless solution, not the old. Previously we only had Monitor or Sensor mode on the 1800, 2800, 3800 etc... in the new Cat9k, cisco introduced Sniffer Mode that allows wireless clients to connect for tshoot purposes, and thats the one Cisco wants to hear, so don't fall for this one its a little tricky as I would have also voted Sensor mode but its not, its Sniffer Mode.
