When LAG is enabled, all ports participate in LAG by default.
Which statement about LAG is true?

A. B. C. D.B.
LAG (Link Aggregation Group) is a technique that enables multiple physical links between two switches to be combined into one logical link. This provides several benefits such as increased bandwidth, redundancy, and load balancing. When LAG is enabled, all ports in the group participate in LAG by default, and the group is treated as a single logical port.
Regarding the given statements, only one statement is true, which is:
B. If any single link fails, traffic will automatically migrate to the remaining links.
This statement is true because when LAG is enabled, multiple physical links are aggregated into a single logical link. If one of the links fails, traffic will automatically migrate to the remaining links, ensuring that there is no disruption to the network. This provides redundancy and high availability.
Regarding the other statements:
A. The failure of one link affects only management access, not traffic throughput.
This statement is not true because the failure of one link can affect both management access and traffic throughput. If a link fails, the traffic that was being carried on that link will be redirected to the remaining links, which can cause increased traffic load and potentially impact network performance.
C. If only two switch ports are in the LAG group, and one switch port fails, then the other switch port will fail also.
This statement is not true because LAG provides redundancy, and if one link fails, traffic will automatically migrate to the remaining links. If only two switch ports are in the LAG group and one port fails, the other port will continue to operate normally.
D. If there are only two LAG connections, then all VLANs must be allowed.
This statement is not true because the number of LAG connections does not dictate which VLANs are allowed. The allowed VLANs are configured independently of the LAG configuration.
