Having implemented a custom API in MCS, you notice that the console.log(<log message>) messages that you included in your code are not appearing in the custom code diagnostic logs.
Identify a reason that you do not see the console.log messages, given that everything else in the API seems to be working properly. (Choose the best answer.)

• A.Your logging level is set to record only more serious log messages (such as severe).
• B.You can record only one logging level at a time.
• C.You have configured that all log messages go to an exportable JSON, XML, CSV, or text file.
• D.You have a typo or have misspelled console.log in your API implementation.
• E.The console.log messages are recorded only after you deploy to a production instance.

Which statement is true about the possibility of a mobile application making API calls to MCS without passing the security credentials that are obtained from a user?

• A.It is not possible because authentication is mandatory for security reasons.
• B.It is possible when using OAuth2 and Client Credential Flow.
• C.It is possible through anonymous authentication, although some platform APIs will offer reduced functionality.
• D.It is not possible because of technical limitations in OAuth and HTTP Basic.

Log messages can be filtered by application session, user, device ID, and correlation ID.
Which statement accurately describes what the correlation ID can tell you in a log entry?
(Choose the best answer.)

• A.It associates a log entry with a specific mobile use case.
• B.It identifies all log entries that are written for a single request regardless of which log files hold the information.
• C.It associates logs written for a specific application with a device.
• D.It identifies the regional location of a request in the log entry.

The green circle indicates that the development instance is working within "Normal" parameters. Which statement accurately comments on "Normal" in this context? (Choose the best answer.)

• A."Normal" is defined on a mobile backend when it is published.
• B."Normal" is automatically set based on the subscribed service-level agreements (SLAs) of the cloud infrastructure managed by Oracle.
• C.The system administrator is prompted to define values such as "Normal" when provisioning an instance of MCS.
• D.Values such as "Normal" are defined as settings by the services developer for each mobile backend.
• E."Normal" is based on a value defined in a policies file that can be updated by a system administrator for each MCS instance.

You are implementing a custom API in Node.js that must call two connectors in a defined sequence to support a transaction. Which statement is true in this context? (Choose the best answer.)

• A.The MCS custom API Node implementation includes a server-side Node SDK that inherently supports transaction management for connector API calls.
• B.Within the MCS UI, you can define a hierarchical relationship between connectors such that, when called from Node, the call order is implicitly set so that the parent connector is called first and the child is called next.
• C.You may nest the second connector call in the callback of the first connector call, or include third party node modules, such as Bluebird, to provide synchronous capabilities.
• D.Because of the asynchronous nature of Node.js, there is no way to guarantee that the connectors will be called in a defined order. You must handle an incorrect outcome in an exception handler.
