A customer is using stacked Aruba CX 6200 and CX 6300 switches for access and a VSX pair of Aruba CX 8325 as a collapsed core 802 1X is implemented for authentication. Due to the lack of cabling, some unmanaged switches are still in use Sometimes devices behind these switches cause network outages The switch should send a warning to the helpdesk when the problem occurs You have been asked to implement an effective solution to the problem

Answers
D.

Suggested answer: C

Explanation:

This is the correct solution to the problem of devices behind unmanaged switches causing network outages due to loops. Loop protection is a feature that allows an Aruba CX switch to detect and prevent loops by sending loop protection packets on each port, LAG, or VLAN on which loop protection is enabled. If a loop protection packet is received by the same switch that sent it, it indicates a loop exists and an action is taken based on the configuration. Loop protection should be configured on all edge ports of the Aruba CX 6200 and CX 6300 switches, which are the ports that connect to end devices or unmanaged switches. The trap-option should be set up to send a warning to the helpdesk when a loop is detected. The other options are incorrect because they either do not configure loop protection or do not set up the trap-option.
