If switch A has an interface configured in dynamic auto mode that is connected to switch B, in which mode does switch B's interface need to be configured to ensure the link between them becomes a trunk?

Question

A) Trunk
B) Auto
C) Dynamic
D) Desirable

Answer 1

A, D
Explanation: A) Four different trunking modes can be configured: Access, Trunk, Dynamic Auto, and Dynamic Desirable. On most modern lower-level switches, the default is Dynamic Auto. When in Access or Trunk modes, the interface is statically placed in each mode. When using the Dynamic Auto mode, the interface will negotiate a trunk but will not actively attempt to trunk; when in Dynamic Desirable mode, the interface will negotiate a trunk and WILL actively attempt a trunk. By default, an interface that is configured as a static trunk will also attempt to actively trunk with any connected device.
