In the IEEE 802.11 standard, wireless frames are categorized into three main types. When a client utilizes 802.11v BSS Transition Management to receive roaming recommendations from the AP, which frame type is used for this exchange?
Show answer details
Correct answer: C
The 802.11v BSS Transition Management Query and Request/Response messages are sent as Action frames. Action frames are a subtype of Management frames. Management frames handle the establishment and maintenance of the wireless connection, whereas Control frames (like ACK, RTS/CTS) assist with channel delivery, and Data frames carry the actual upper-layer payloads.

A university is deploying a Cisco SD-Access wireless architecture. The design requires that wireless client MAC addresses be registered in the LISP host tracking database, while the data plane traffic is encapsulated in VXLAN and forwarded directly to the fabric edge.
Which component in the SD-Access architecture is responsible for handling the CAPWAP control plane traffic from the Fabric APs?
Show answer details
Correct answer: B
In a Cisco SD-Access Wireless (Fabric Wireless) architecture, the APs establish a CAPWAP control tunnel to the Fabric WLC (Catalyst 9800) to handle management, RRM, and client authentication. However, the data plane is separated; data traffic is encapsulated in VXLAN by the Fabric AP and sent directly to the Fabric Edge node (switch), bypassing the WLC for data forwarding.

When implementing the physical infrastructure connections for high-throughput Wi-Fi 6E access points (such as the Catalyst 9136), which TWO considerations are essential for maximizing AP performance and ensuring proper power delivery? (Select TWO)
Show answer details
Correct answer: A, C
Wi-Fi 6E access points with multiple high-capacity radios (2.4 GHz, 5 GHz, 6 GHz) can easily exceed the throughput of a standard 1 Gbps Ethernet connection, necessitating Multigigabit (mGig) switchports. Additionally, powering all radios and advanced features requires more power than older standards provide, demanding 802.3bt (PoE++ / UPOE) capable switches to operate without degrading functionality.

While evaluating a warehouse environment for a new Wi-Fi 6 deployment, an architect notes that the noise floor in the 5 GHz band is consistently measured at -92 dBm. The automated guided vehicles (AGVs) require a minimum Signal-to-Noise Ratio (SNR) of 25 dB to maintain the 64-QAM modulation required for their telemetry application. Based on these parameters, what is the minimum acceptable Received Signal Strength Indicator (RSSI) the AGVs must perceive?
Show answer details
Correct answer: D
SNR (Signal-to-Noise Ratio) is calculated as the difference between the received signal strength (RSSI) and the noise floor. The formula is: SNR = RSSI - Noise Floor. To find the minimum RSSI, rearrange the formula: RSSI = SNR + Noise Floor. Given an SNR requirement of 25 dB and a noise floor of -92 dBm, the calculation is 25 + (-92) = -67 dBm.

During an outdoor point-to-point bridge installation, the field technician mounts one directional antenna vertically and the receiving antenna horizontally. Which RF phenomenon will severely impact the link budget in this scenario?
Show answer details
Correct answer: D
Antenna polarization describes the orientation of the electric field of the radio wave. If a transmitting antenna is vertically polarized and the receiving antenna is horizontally polarized, there is a 90-degree mismatch. This results in cross-polarization loss, which can attenuate the signal by as much as 20 dB or more, severely degrading the link budget.

True or False: Equivalent Isotropically Radiated Power (EIRP) is calculated by adding the transmitter power to the antenna gain, and then subtracting any cable loss.
Show answer details
Correct answer: A
True. EIRP is the total actual power radiated by the antenna. It is calculated as: EIRP = Transmitter Power (dBm) - Cable/Connector Loss (dB) + Antenna Gain (dBi).
