A Lambda CodeDeploy release must run validation hooks and detect failures before completing alias traffic shifting. Which configuration elements are relevant? Select 2 answers.

1. Configured lifecycle validation hooks that report their execution outcomes through the required mechanism.
2. A supported AppSpec revision that identifies the function, alias, and intended versions.
3. An AppSpec that points both old and new versions to an unrelated function.
4. Hooks that always report success before performing any checks.
5. Only a README saying that tests were run, with no deployment validation integration.
