Which statement about link aggregation is false?

Link aggregation is a technique used to combine multiple network connections in parallel to increase throughput and provide redundancy. The statement indicating that link aggregation involves only the active interface is false because link aggregation includes both active and standby links.

In a typical link aggregation scenario, multiple physical links are grouped together into one logical connection. While some links may actively carry traffic, others can be in a standby or inactive state, ready to take over should an active link fail. This redundancy is essential for maintaining network reliability, as it prevents a single point of failure from disrupting communications.

The other statements accurately reflect the principles of link aggregation. It indeed increases bandwidth and reliability by allowing the simultaneous use of multiple links, supports the IEEE 802.3ad standard for link aggregation, and involves the creation of a Link Aggregation Group (LAG) that logically groups the bundled physical links together.
