1 - Server derived role
2 - User derived role
3 - Authentication default role
4 - Initiation role assigned

Explanation
The correct answer is B. An event log message is created.
The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.
The other options are incorrect because:
* A. Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable1.
* C. The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.
* D. Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.

The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.

Explanation
Aruba Installer App is a mobile app that simplifies site installations and enables network connectivity for Aruba devices. The app allows the user to scan the barcode of the device and add it to the network using Aruba Central. The app also automates importing Aruba devices into Aruba NetEdit for intelligent configuration management and continuous conformance validation

Explanation
a) Support up to 10 devices per stack -> VSF
b) Support two devices per stack -> VSX
c) Individual ISL links up to 400G are supported -> VSX
d) individual ISL links up to 50G are supported -> VSF
e) A maximum aggregate ISL bandwidth of 200G is supported -> VSF
