Explanation: B. Review the log file ‘CreateEnv.log’ and investigate any error messages it contains.
This is the best option because the CreateEnv.log file records the steps and results of creating the CP environment in the Vault during the installation. The CP environment includes the safe, the provider user, the application user, and the application identity. If any errors occurred when creating the CP environment, they will be logged in this file and may indicate a problem with the Vault connection, the credential file, the permissions, or the configuration. Reviewing the log file can help to identify and resolve the root cause of the errors and ensure the CP environment is properly set up.
Continuing configuring the application to use the CP without further action is not a good option because it may lead to unexpected or inconsistent behavior of the CP or the application. The errors that occurred when creating the CP environment may affect the security, availability, or integrity of the credentials or the application. Ignoring the errors may also make it harder to troubleshoot or fix them later.
Running setup.exe again and selecting ‘Recreate Vault Environment’ is not a good option because it may overwrite or delete the existing CP environment and cause more errors or conflicts. Recreating the Vault environment should only be done after reviewing the log file and understanding the cause of the errors. Moreover, recreating the Vault environment may require more privileges than creating it for the first time, as some objects may be already in use or locked.
Reviewing the PVWA logs to determine which REST API call used during the installation failed is not a good option because it may not provide enough information or context to understand or resolve the errors. The PVWA logs may show the HTTP status codes or messages of the REST API calls, but they may not show the details or parameters of the calls or the responses. The PVWA logs may also contain other unrelated or irrelevant entries that may confuse or distract from the errors. The CreateEnv.log file is a more specific and reliable source of information for the errors that occurred when creating the CP environment.
