Which two statements are true about accessing cloud-based storage through the storage API? (Choose two.)

• A.It can store images and JSON objects.
• B.It is a convenient way of storing data that is specific to your mobile application without having to go back to your back-end systems to store it.
• C.It is the principal way of retrieving data from back-end, on-premise systems.
• D.All data retrieved from back-end applications must be stored by the storage API in order to be consumed by the mobile application.
• E.It gives you full access to an Oracle Database instance.

Which two statements are true about exporting and importing packaged artifacts in MCS?
(Choose two.)

• A.MCS resolves the naming and version conflicts of an artifact that is imported from a package, if the same artifact exists in the target MCS environment.
• B.The artifacts that are exported or imported as a package keep their version numbers.
• C.Environment policy values such as the endpoint value of a specific version of a REST connector can be changed during the export and altered after the import of a package.
• D.The version string of a package must match the version of the exported mobile backend.

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.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.
• B.The MCS custom API Node implementation includes a server-side Node SDK that inherently supports transaction management for connector API calls.
• C.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.
• 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.

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.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.
• B.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.
• C.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.
• 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.

Which statement is true about establishing a security policy for a connector API?

• A.You do not have to take a client's authentication type into account when selecting a security policy for a connector API because security configuration is totally decoupled for clients and connector APIs.
• B.You must take a client's authentication type into account when selecting a security policy for a connector API, but only if HTTPS connections are used.
• C.You do not have to take a client's authentication type into account when selecting a security policy for a connector API, except when Facebook social login is used.
• D.You must take a client's authentication type into account when selecting a security policy for a connector API because mobile clients and connector APIs must use the same type of authentication for successful operation.
• E.You must take a client's authentication type into account when selecting a security policy for a connector API, but only when using OAuth2 and Client Credential Flow.
