質問 2：
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. You have configured that all log messages go to an exportable JSON, XML, CSV, or text file.
B. The console.log messages are recorded only after you deploy to a production instance.
C. Your logging level is set to record only more serious log messages (such as severe).
D. You can record only one logging level at a time.
E. You have a typo or have misspelled console.log in your API implementation.
正解：B

質問 3：
A mobile application that is installed on a mobile device was successfully registered to MCS by using the notifications device registration REST endpoint. Which two statements are true about what this means for the application's ability to send and receive push notifications? (Choose two.)
A. The application instance on the mobile device can send push notifications through MCS that are then dispatched to all mobile clients registered for the application in MCS.
B. Push messages can be received only if a valid token is provided with the MCS device registration that was previously obtained from APNs, GCM, or WINS.
C. MCS can send push messages directly to the application on the device by using a web socket connection that is kept open until the device unregisters from MCS.
D. MCS can schedule notifications to be sent to the application instance on the device and messages are routed via push delivery networks such as APNs, GCM, or WINS.
正解：C,D

質問 4：
Custom API implementations are developed with Node.js and can contain log messages for display in the MCS Administration Logs panel. Which line of Node.js code logs "Hello World" from an MCS custom API?
A. system.out.println("INFO","Hello World");
B. logger.inf("Hello World");
C. console.inf("Hello World");
D. req.oracleMobile.inf("Hello World");
正解：D

質問 5：
You have developed Android and iOS applications that send custom events to MCS. Which statement is true about what happens when the applications lose network connectivity?
(Choose the best answer.)
A. No analytic events can be sent to MCS when there is no network connection.
B. The iOS and Android operating systems automatically cache REST calls when they are offline and will replay them when connectivity is restored.
C. If you have used an appropriate MCS client SDK, analytic events will be written to a file, which can be manually uploaded into MCS.
D. If you have used an appropriate MCS client SDK, analytic events will be cached and sent when connectivity is restored.
正解：C

質問 6：
Which two statements are true about the authentication features of MCS? (Choose two.)
A. All MCS mobile users must have their own accounts in the enterprise back-end systems that are leveraged by the custom APIs.
B. Anonymous authentication is a misnomer because mobile apps do not actually perform authentication to MCS when they are configured to use anonymous authentication.
C. When a mobile user is authenticated, the authentication is valid for all the MCS instances owned by an organization.
D. The authentication technology that is used by a mobile application to connect to a backend can be different from the one that is used by a connector to authenticate against a remote enterprise system. For example, an application can authenticate to MCS over HTTP Basic and the connector can authenticate by using OAuth on a remote web service.
E. The user accounts that are used to access Software as a Service (SaaS) offerings, such as Oracle HCM Cloud, can be used as MCS mobile user accounts if they are assigned to the appropriate security roles in Oracle Cloud.
F. Each mobile backend is associated with a single user realm and each realm can be associated with only one backend.
正解：D,E

質問 7：
Which statement accurately describes the primary purpose of the MCS client SDKs?
A. They are the only way of calling MCS REST APIs from a mobile client.
B. They provide a single programming language for accessing MCS REST APIs from a mobile client.
C. They simplify the process of calling MCS REST APIs from a mobile client.
D. They must be used if you want to securely authenticate against MCS.
正解：C
