An engineer has been asked to upgrade the FUS on the Wireless LAN controller. How can they monitor the status of the upgrade?
An engineer has been asked to upgrade the FUS on the Wireless LAN controller. How can they monitor the status of the upgrade?
To monitor the status of the upgrade of the FUS on the Wireless LAN Controller, the best approach would be using the WLC CLI. The Command Line Interface (CLI) provides detailed and real-time monitoring capabilities making it the most reliable way to trace the progress of a software upgrade on networking devices. The WLC GUI and WLC Management in Prime Infrastructure are useful for other administrative tasks, but for real-time upgrade monitoring, the CLI is preferred.
A wireless engineer has been asked to plan a deployment covering the aisles of a warehouse with optimal coverage while bleeding RF across aisles. Which antenna type provides the necessary coverage?
In a warehouse setting, to cover aisles optimally while ensuring the radio frequency (RF) signal bleeds across the aisles, an omnidirectional antenna is the best choice. An omnidirectional antenna radiates RF signals uniformly in all directions, providing widespread coverage that can extend across multiple aisles. This uniform distribution is essential for ensuring consistent coverage and connectivity throughout the warehouse, including the spaces between aisles.
After you configure the Cisco 5508 Wireless Controller v7.6, a customer requests an SSID that allows for client web authentication with email input. Which authentication method should be used?
The correct option for enabling client web authentication with email input is 'pass-through'. This method allows users to enter an email address without requiring additional credentials, providing a seamless connection process. After users input their email, they are granted access, and their email is recorded as their username.
Which two principles must be considered when deploying a wireless network through a wooded area? (Choose two.)
When deploying a wireless network through a wooded area, absorption and scattering are two critical principles to consider. Absorption is significant because the trees and vegetation will absorb some of the wireless signal, reducing its strength. Scattering occurs as the signal encounters numerous obstacles, like leaves and branches, which cause the signal to spread in various directions, affecting the overall network performance.
A network engineer notices that two mesh APs are having problems communicating. After reviewing the current radio configurations, it is noted that one AP is transmitting at 3 mW while the other is transmitting at 60 mW. How many decibels would the 3-mW AP need its power increased to match the 60-mW AP?
The decibel calculation for power increase follows logarithmic scales. To determine the increase in power in decibels (dB) to go from 3 mW to 60 mW, you use the formula: dB = 10 * log10(P2/P1), where P2 is the final power and P1 is the initial power. Applying the values: dB = 10 * log10(60/3). This simplifies to dB = 10 * log10(20) ≈ 10 * 1.301 = 13.01. Therefore, the 3-mW AP needs its power increased by approximately 13 dB to match the 60-mW AP.
