Which three pairs of trunking modes will establish a functional trunk link between two Cisco switches? (Choose three.)
- access – trunk
- dynamic auto – dynamic auto
- dynamic desirable – dynamic desirable
- dynamic desirable – dynamic auto
- dynamic desirable – trunk
- access – dynamic auto
Answers Explanation & Hints: - access with trunk: This combination will not establish a functional trunk link because access ports do not participate in trunking.
- dynamic auto with dynamic auto: This combination will not establish a functional trunk link because both interfaces will wait for the other end to initiate trunking.
- dynamic desirable with dynamic desirable: This combination will establish a functional trunk link because both interfaces will actively try to initiate trunking.
- dynamic desirable with dynamic auto: This combination will establish a functional trunk link because the dynamic desirable side will initiate trunking and the dynamic auto side will respond and negotiate the trunking.
- dynamic desirable with trunk: This combination will establish a functional trunk link because the dynamic desirable side will initiate trunking and the trunk side will accept the trunking.
- access with dynamic auto: This combination will not establish a functional trunk link because access ports do not participate in trunking and dynamic auto will not initiate trunking.
