When configuring SNMP v3 on a wireless LAN controller, which security feature is NOT available in SNMP v1 or v2c?
Answer: Message authentication and encryption
SNMP v3 adds user-based authentication (MD5/SHA) and optional encryption (DES/AES), which are absent in v1/v2c that rely only on plaintext community strings.
A CWS technician uses Metageek Chanalyzer with a Wi-Spy adapter. What type of data does this combination primarily provide?
Answer: Raw RF spectrum utilization across 2.4 GHz and 5 GHz bands
Wi-Spy is a USB spectrum analyzer that, paired with Chanalyzer software, displays real-time RF energy across the 2.4 and 5 GHz spectrums.
In a Cisco Catalyst Center (formerly DNA Center) managed wireless deployment, what is the role of the 'assurance' module?
Answer: To continuously monitor network health, detect anomalies, and provide root cause analysis
The Assurance module provides AI/ML-driven monitoring of device health, client experience, and automated root cause analysis for network issues.
A technician performing a post-deployment validation survey finds that measured signal levels are weaker than the predictive model showed. What is the MOST likely cause?
Answer: Actual building materials have higher attenuation than modeled in the simulation
Predictive models use estimated attenuation values for walls and materials; actual construction with concrete, metal, or insulation often attenuates more than default assumptions.
Which wireless network management feature automatically adjusts AP transmit power and channel assignments to optimize coverage and reduce co-channel interference?
Answer: Radio Resource Management (RRM)
RRM (also called auto-RF or dynamic channel assignment) continuously monitors the RF environment and automatically optimizes power levels and channel allocations.
A technician wants to verify whether a specific 802.11ac AP is supporting MU-MIMO transmissions. Which tool provides the most direct evidence?
Answer: A Wireshark capture showing VHT-SIG-A fields in 802.11ac frame headers
The VHT-SIG-A field in 802.11ac (VHT) frames contains MCS, spatial stream count, and TXOP information that reveals MU-MIMO group membership.
In cloud-managed Wi-Fi platforms, what is the typical method used to onboard a new AP to the management system without manual configuration?
Answer: Zero-touch provisioning using the device serial number claimed in the dashboard
Zero-touch provisioning allows APs to automatically download their configuration from the cloud using a serial number claimed in advance on the management portal.
