질문 # 119
A wireless network uses RRM to optimize radio performance dynamically. Which two parameters are automatically adjusted by RRM?
정답：A
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 # 120
How does MIMO operate during wireless transmission?
정답：A
설명：
MIMO, or Multiple-Input Multiple-Output, is a core 802.11n and later wireless technology that uses multiple transmit and receive radio chains and antennas to improve wireless performance.
Cisco's Wireless RF Reference Guide explains that IEEE 802.11n introduced MIMO, replacing the older single-radio SISO model with multiple radios, each using its own antenna, to increase data rates and improve reception in multipath environments. Cisco also notes that weak or distorted multipath signals can be received by more than one radio and reconstructed, improving decode quality and reliability.
This directly supports option A: MIMO exploits multiple RF paths rather than treating multipath as purely destructive. Depending on implementation, MIMO can use spatial diversity, maximal ratio combining, and spatial streams to increase throughput, improve signal-to-noise ratio, reduce retries, and make more efficient use of airtime. Cisco describes spatial stream notation such as
4x4:4 as four transmitters, four receivers, and four spatial streams. Option B describes frequency hopping, not MIMO. Option C is not a MIMO function. Option D is the opposite of MIMO because MIMO deliberately uses multiple antennas and radio paths.
질문 # 121
Which feature does bridge mode provide in a Cisco wireless mesh architecture?
정답：A
설명：
Bridge mode in a Cisco wireless mesh deployment allows access points to operate as mesh infrastructure nodes, typically as a Root AP (RAP) or Mesh AP (MAP), so Ethernet segments can be connected across a wireless backhaul. Cisco's mesh design documentation states that in a point-to-point bridging scenario, a mesh AP can extend a remote network by using the backhaul radio "to bridge two segments of a switched network." This directly maps to option A: point-to-point communication between network segments.
In Catalyst 9800 mesh deployments, Cisco documents converting an AP to bridge mode withcapwap ap mode bridge, after which the AP rejoins the controller in bridge mode and can be assigned a mesh role. Cisco also defines the RAP as the AP with the wired connection toward the WLC, while the MAP joins through its radio path toward the RAP. Option B is incorrect because bridge mode does not force all traffic to 2.4 GHz; Cisco mesh backhaul can use configured backhaul radios. Option C describes RRM/TPC behavior, not bridge mode.
Option D incorrectly associates mesh bridge mode with WAN edge functions. Reference topics:Wireless Network Implementation - mesh AP roles, RAP/MAP operation, wireless backhaul, and Ethernet bridging.

질문 # 122
A wireless engineer wants to analyze over-the-air 802.11 frames without servicing clients. Which AP mode should be configured?
정답：D
설명：
Sniffer mode converts an AP into a dedicated packet capture device that forwards 802.11 frames to a protocol analyzer such as Wireshark. This mode is commonly used for troubleshooting wireless issues. Local and FlexConnect modes continue servicing wireless clients instead.
질문 # 123
An organization must manage ongoing firmware updates for redundant controllers in the network. They will use Cisco Catalyst Center for deployment and visibility. The current environment uses centralized and distributed management approaches. Automation and reporting are critical to minimize operational workload.
Which method must be used to manage structured update processes and monitor progress throughout the update cycle?
정답：C
설명：
The correct method issoftware image management workflows, specifically Cisco Catalyst Center Software Image Management, commonly referenced as SWIM. Cisco documents SWIM as the mechanism used to manage software upgrades and maintain consistency of image versions across the network. It provides an image repository, golden-image assignment, image distribution, activation, readiness checks, and scheduled execution. Cisco's wireless automation guidance specifically states that SWIM is used to update Catalyst
9800 Series Wireless Controller software by distributing the image from the Catalyst Center repository to wireless controllers and upgrading the images running on those controllers; both stages can run immediately or be scheduled for a defined maintenance window.
Option C is also validated by Catalyst Center's update-status and workflow views. Cisco documentsImage Update Statusas the view that shows all update tasks, filters by in-progress, success, or failure, and displays a progress bar for active updates. The workflow view then exposes distribution and activation task status, timing, prechecks, postchecks, checksum verification, and AP pre-image download details. Inventory snapshots and templates do not execute controller firmware upgrades, and "lifecycle workflow" is too generic.
Reference topics:Wireless Monitoring and Management - Catalyst Center SWIM, image compliance, golden images, controller upgrade automation, and update progress reporting.
