What are the options for configuring an EtherChannel?

When configuring an EtherChannel, the options available include both static and dynamic protocols, making this the correct answer. Static EtherChannel requires manual configuration, where all parameters must match on both ends, ensuring that the interfaces are bundled as a single logical link without any negotiation. This method is straightforward, as administrators set up the channel explicitly to work as intended.

Dynamic protocols, such as Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP), facilitate the automatic negotiation of the EtherChannel configuration between the devices. These protocols can add or remove connections based on the current network conditions, offering flexibility and resilience to changes in the network.

In contrast to the correct answer, the other options do not accurately represent the methodology for configuring an EtherChannel. Manual and automated options refer more broadly to configurations and do not specifically detail the protocols used for EtherChannel. Configured and non-configured methods are not terminologies typically associated with EtherChannel setup. Additionally, static and adaptive configurations are not standard classifications. The distinct separation into static configurations and dynamic protocols best captures the options network professionals use when implementing EtherChannel.
