What type of aggregation mode is used by LACP?A. StaticB. Packet negotiationC. Per-flowD. Bridge MAC

The Link Aggregation Control Protocol (LACP) uses Packet Negotiation as its aggregation mode. This means that it dynamically manages the aggregating of network links to ensure the best utilization and redundancy. The other options, Static, Per-flow, and Bridge MAC, are not used by LACP.

Here's a step-by-step breakdown:

1. LACP is a protocol used in networking to bundle several physical ports together to form a single logical channel. This is known as link aggregation.

2. The purpose of link aggregation is to increase the network's bandwidth and provide redundancy in case one of the physical links fails.

3. LACP uses the Packet Negotiation mode of aggregation. This means it can dynamically identify links that are connected between different network devices and bundle them together to form a single, higher-bandwidth link.

4. In contrast, Static aggregation requires manual configuration and does not have the ability to dynamically identify and configure links.

5. Per-flow and Bridge MAC are not aggregation modes used by LACP. Per-flow balancing is a method of distributing network traffic, while Bridge MAC refers to the MAC address of a network bridge device.
