Which two of the following options correctly define the characteristics for EtherChannel? (Choose two.)
- high bandwidth
- load sharing across links
- low convergence timing
- server scalability
- multiple logical ports for RSTP+
Explanation: EtherChannel technology is specifically designed to aggregate multiple physical Ethernet links into a single logical link to overcome bandwidth limitations and provide redundancy. According to the sources, the primary characteristics of EtherChannel include providing high bandwidth by combining the capacity of up to eight physical ports and enabling load sharing across links to distribute traffic efficiently. This aggregation allows the Spanning Tree Protocol (STP) to treat the bundle as one logical port, which prevents loop-avoidance mechanisms from blocking redundant paths and ensures all physical links remain active. While EtherChannel does improve network resilience and allows for faster recovery if a single link fails, its core definitions in the technical documentation emphasize the increase in total throughput and the ability to balance traffic across the aggregated members. Therefore, high bandwidth and load sharing are the fundamental characteristics that define its operational purpose in a campus network.
