Creating and Publishing Tag v3.0.5 with git tag and git push origin v3.0.5

Why the Answer Is Correct

Two distinct actions are needed because a Git tag lives in two places. The first is creating the tag at the current commit locally, which is what git tag v3.0.5 does, naming it so it can be referenced. The second is transferring that ref to the remote repository, which is what git push origin v3.0.5 does with the explicit tag name as the refspec. Only after the push does the tag exist in the remote repository and become available to other clones. The vote was unanimous at 100 for B and C, and UrbanRellik stated the pair concisely as the two commands to run in order.

Why the Other Options Are Wrong

The command git commit -m 'tag v3.0.5' (D) creates a commit whose message happens to contain the text tag v3.0.5, which is not a tag at all. The string lives in the commit log and has none of the ref semantics a tag requires, so it neither creates v3.0.5 nor publishes anything. The command git add 'tag v3.0.5' (E) stages a file whose name is tag v3.0.5, which stages a file path rather than a ref, so it accomplishes nothing toward creating a tag unless such a file exists, in which case it merely stages it. Using git push -force (A) forces the remote ref to be overwritten, which is a destructive operation intended for rewriting history. A newly created tag conflicts with nothing, so forcing is unnecessary and introduces a risk of discarding remote state.

Community Comment Notes

The community was unanimous at 100 for B and C, and the single substance comment from UrbanRellik gave the answer as the two commands in execution order, which is exactly the right level of detail for a two-command question. The absence of further debate reflects that the question has no genuine ambiguity: creating a tag locally and then pushing it are separable operations and both are required, so the two selections are complementary halves of one solution rather than competing answers.
