예를 들어Cisco 350-101 덤프를 보면 어떤 덤프제공사이트에서는 문항수가 아주 많은 자료를 제공해드리지만 저희Cisco 350-101덤프는 문항수가 적은 편입니다.왜냐하면 저희는 더 이상 출제되지 않는 오래된 문제들을 삭제해버리기 때문입니다. 문제가 많으면 고객들의 시간을 허비하게 됩니다. Pass4Test는 응시자에게 있어서 시간이 정말 소중하다는 것을 잘 알고 있습니다.
질문 # 126
A wireless network uses RRM to optimize radio performance dynamically. Which two parameters are automatically adjusted by RRM?
정답：C
설명：
Radio Resource Management dynamically adjusts AP channel assignments and transmit power levels to reduce interference and improve wireless performance. RRM continuously analyzes RF conditions across the environment. It does not modify Layer 3 services such as DHCP, routing, or NAT operations.
질문 # 127
A persistent network issue is impacting connectivity for workstations in a training lab when connecting to a lab SSID. Wireless logs show clients never receive a DHCP offer when trying to obtain an IP address. The APs are operating in Local mode. Network monitoring systems indicate optimal signal quality and radio performance, VLAN assignments for the affected SSID have been configured, and all clients are affected.
Which action resolves the issue?
정답：B
설명：
The fault domain is DHCP forwarding, not RF, client-side addressing, or AP discovery. Cisco explains that when a wireless client associates, it sends a DHCP Discover broadcast, and depending on AP mode, that traffic is either forwarded through the WLC or passed to the next hop. Cisco further states that if no DHCP server exists in the client's local Layer 2 domain, the router or SVI for the client VLAN must forward DHCP discovery traffic using an IP helper address.
Because the APs are inLocal mode, client traffic is centrally switched through CAPWAP to the WLC, where the client VLAN/SVI path must correctly relay DHCP toward the DHCP server. Cisco's Catalyst 9800 DHCP configuration guide shows DHCP relay configuration under the client VLAN SVI by entering the IPv4 helper address, and the CLI example usesip helper-address < ip-address > to forward UDP broadcasts such as DHCP requests.
Option C resolves the issue because all clients are affected and none receive a DHCP offer, indicating the DHCP Discover is not reaching the DHCP server or the offer is not returning through the relay path. DHCP option 43 is for AP controller discovery, not client DHCP addressing. Reference topics:DHCP relay, Local mode AP forwarding, Catalyst 9800 client VLANs, and wireless client IP assignment.
질문 # 128
How does the optimized roaming function operate in a WLC implementation?
정답：A
설명：
Optimized roaming is a Cisco WLC feature designed to reduce sticky-client behavior. A sticky client remains associated to an AP even after moving far enough away that another AP would provide better RF service.
Cisco describes optimized roaming as actively monitoring client data RSSI and disconnecting clients when received signal strength falls below the configured threshold. The official Catalyst 9800 documentation states that optimized roaming "disassociates client when the RSSI is lower than the set threshold," which directly matches option A.
This function does not calculate device location through peer-to-peer beaconing, does not depend on external experience services, and is not static load balancing. It is an RF/client-roaming enforcement mechanism controlled by the wireless infrastructure. In practical operation, the AP/WLC evaluates client signal quality and, when the configured optimized roaming criteria are met, forces the client to disconnect so it can reassess the RF environment and roam to a better AP. Cisco also notes that optimized roaming helps maintain client connectivity by managing disassociationn based on RSSI and data-rate thresholds.

질문 # 129
What does a low SNR value result in?
정답：C
설명：
TheSignal-to-Noise Ratio (SNR)is an important metric used to determine the quality of a wireless signal. It compares the strength of the signal to the level of background noise. A low SNR indicates that the signal is weak relative to the noise, leading to poor signal quality.
Option D: Decreased data integrity with possible errorsis the correct answer. When SNR is low, the quality of the data transmission is compromised. The noise interferes with the signal, leading to potential data errors and a decrease in data integrity. This can cause packets to be lost or corrupted, requiring retransmissions, and reducing the overall performance and reliability of the network.
Option A: Scheduling of firmware maintenance windowsis not directly related to SNR. Firmware maintenance is unrelated to signal quality, though it might be necessary for other reasons, such as performance optimization or bug fixes.
Option B: Activation of automatic failover featuresis typically used in scenarios where there is network equipment failure or poor connection quality, but it is not directly triggered by low SNR values.
Option C: Improved channel reliabilityis the opposite of what happens when SNR is low. Low SNR leads to unreliable communication, not improved reliability.
Therefore,Option Dis correct, as a low SNR results in decreased data integrity due to possible errors in the transmission process.
질문 # 130
What is used for measuring gain on a Wi-Fi antenna?
정답：A
설명：
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.
