Morphology
The phrase is a straightforward simile using the comparative pattern 'as ... as'; a learner who knows 'dumb', 'as', and that a 'post' is an inanimate stake can infer the meaning 'extremely stupid or unresponsive'. This compositional, comparative logic is common across languages and follows standard English patterns, so the overall meaning is directly derivable from the parts.
Etymology
Dumb as a post may come from the image of a wooden post that stands silent and does not move, and calling someone dumb like that suggests they are 'very stupid' or 'not reacting'.
