What term describes the method of grouping multiple physical Ethernet links into a single logical link?

• A. Link Aggregation
• B. Virtual LAN
• C. Inter-VLAN Routing
• D. Spanning Tree Protocol

Answer: (A)

The term that describes the method of grouping multiple physical Ethernet links into a single logical link is Link Aggregation. This technique enhances bandwidth and provides redundancy by enabling the simultaneous transmission of data across several links. When multiple physical links are combined into one, they act as a single logical link from a network protocol perspective. This can lead to improved performance due to increased throughput and greater resilience since if one link fails, the others remain operational. Link aggregation is commonly implemented using protocols such as LACP (Link Aggregation Control Protocol), which helps in automatically configuring and managing the aggregated links to prevent issues like loops and ensure balanced traffic distribution. On the other hand, Virtual LANs (VLANs) create a segmented network within a switch, isolating broadcast domains without requiring additional hardware. Inter-VLAN Routing refers to the routing process between VLANs to facilitate communication, and Spanning Tree Protocol (STP) is used to prevent loops in bridged networks. Each of these concepts serves different purposes within network design and operations.
