Answers
D.
Modify the timeout to give the task longer to complete.
Suggested answer: C

Explanation:

The error message ''Authentication by <Credential_type> failed'' typically indicates an issue with the authentication credentials being used. Since the administrator is using SSH key-based credential to authenticate, it's essential to ensure that the private key associated with this credential is correct and accessible. If there's an issue with the private key, such as it being incorrect or inaccessible, authentication will fail. Increasing the retries or modifying the timeout will not help if the credential is invalid. Changing to password authentication credential may work, but it's not the best option as it may compromise security and require additional configuration.Reference:
