CompTIA Network+ (N10-009) — Question 330

A network technician is installing a new switch that does not support STP at the access layer of a network. The technician wants a redundant connection to the distribution switch. Which of the following should the technician use?

Answer options

Correct answer: A

Explanation

Link aggregation is the appropriate choice because it allows multiple physical connections to be combined into a single logical connection, providing redundancy and increased bandwidth. The other options, such as subinterfaces and switch virtual interfaces, do not directly address redundancy in physical connections, while half-duplex connections are not suitable for modern switch environments due to their limitations in data transmission.
