Cisco Updated 350-101 Exam Questions and Answers by roma

The requirement is guest client isolation, not merely guest authentication or internet breakout. On a Catalyst 9800 WLC, peer-to-peer blocking is the correct control because it prevents wireless clients associated to the same WLAN from communicating directly with one another. Cisco defines peer-to-peer blocking as a WLAN security feature applied to individual WLANs, where each client inherits the WLAN’s P2P blocking behavior, and traffic can be bridged locally, dropped, or forwarded upstream. For this scenario, the appropriate action is thedropbehavior, because guest-to-guest file sharing must be prohibited while upstream internet access remains available.

The dedicated guest VLAN, VLAN 30, provides traffic segmentation from production networks and creates a clean policy boundary for VisitorAccess. Cisco’s Catalyst 9800 configuration model maps WLANs to policy profiles, and the policy profile defines client network and switching policy, including VLAN association. Options B, C, and D do not solve client isolation: local authentication validates users, FlexConnect/local switching changes traffic forwarding behavior, and multicast/RADIUS does not block unicast guest-to-guest traffic. Reference topics:Client Connectivity Configuration — guest WLAN design, P2P blocking, VLAN segmentation, and Catalyst 9800 WLAN-to-policy mapping.

The correct answer isBbecause Wi-Fi antenna gain is expressed usingdBi, which means decibels relative to an isotropic radiator. Cisco’s Wireless RF Reference Guide states that antenna gain is measured in decibels relative to isotropic gain, ordBi. Cisco RF design documentation also explains that dBi is used to describe the power gain rating of antennas by comparing real antennas against an ideal isotropic antenna that radiates equally in all directions.

Antenna gain is not a measurement of physical antenna length. Length may influence antenna design and resonance, but it is not the operational unit used to express gain. It is also not measured as voltage against dBm.dBmis an absolute power reference relative to one milliwatt, commonly used for transmit power or received signal strength, whiledBidescribes antenna gain. Cisco’s EIRP calculation reinforces this separation: transmitter power is in dBm, antenna gain is in dBi, and cable loss is in dB. A “blend of analog and digital signals” has no RF measurement relevance. Reference topic:RF Fundamentals — antenna gain, dB/dBi/dBm, isotropic radiator reference, EIRP, and RF propagation behavior.

SNMP monitoring provides centralized visibility and event notification for Cisco wireless infrastructure. On Cisco Catalyst 9800 wireless controllers, SNMP traps are used to send alert messages from SNMP-enabled devices to an SNMP manager, and Cisco specifically documents wireless trap support for access points, clients, mesh, RF, rogue, mobility, RRM, and controller events. Cisco also states that AP-related traps such as crash, register, and no-radio-card events are enabled by default, and that configuring AP traps helps monitor AP status and troubleshoot issues.

Therefore, the direct operational benefit isalerts on access point status. SNMP is not limited to hardware-only metrics; it can expose client counts, joined AP counts, processor usage, memory usage, and wireless event notifications through supported OIDs and traps. Manual log review is the opposite of SNMP’s purpose because traps automate notification to a network management system. Fragmented statistics are also incorrect because SNMP enables centralized polling and trap collection across managed devices. Reference topics:Wireless Monitoring and Management — SNMP, MIB/OID monitoring, Catalyst 9800 wireless traps, AP status monitoring, and NMS integration.

The correct Cisco technology isAI Network Analytics. Cisco describes Cisco AI Network Analytics as a Catalyst Center capability that uses machine learning and machine reasoning to generate deployment-specific insights, identify operational issues, and accelerate troubleshooting. Cisco’s official Catalyst Center Assurance documentation states that Cisco AI Network Analytics uses advanced machine learning techniques and an advanced cloud learning platform with deidentified network event data to identify critical issues in the network.

This makes option D the only precise match. Catalyst Center Assurance is the broader assurance and monitoring framework where AI Network Analytics is surfaced, but it is not the specific technology named in the question. Network Services is a generic platform function area, not the AI/ML analytics feature. Catalyst Center LLM Insights is not the established Cisco wireless assurance feature associated with cloud-based machine learning for issue detection. AI Network Analytics provides AI-driven baselining, anomaly detection, root-cause assistance, trends, insights, and comparative benchmarking. Cisco also documents that the AI Network Analytics cloud runs machine learning models using deidentified network event data and returns issues and insights back into Catalyst Center.
