Oracle Mobile Cloud Service 2016 Developer Essentials

Question 1

Which statement correctly describes a functionality of the MCS client SDKs?

A. The MCS SDKs for iOS and Android manage capabilities such as storing data when you work offline.

B. They can be used to call only the MCS platform APIs.

C. They provide a library of native user interface widgets for building features such as login pages.

D. They can be used to call only the custom APIs defined in MCS.

Correct Answer: B

Question 2

Identify four authentication methods that can be configured for an MCS mobile backend.

A. OpenID

B. SAML

C. Enterprise Single Sign-On (SSO)

D. OAuth Consumer

E. Oracle Access Manager Mobile and Social

F. HTTP Basic

G. Facebook Login

Correct Answer: C,D,F,G

Question 3

custom API implementation zip file includes the Node JavaScript file and the package.json file. What is the purpose of the package.json file?

A. This is an artifact generated by MCS when you download the code. It can be safely ignored.

B. For the related Node.js file, it includes all the #import package names.

C. It contains the RAML JSON definition of the custom API's endpoints, methods, and payloads.

D. It is a manifest file for the zip file that specifies the name, version, and dependencies of the Node code.

Correct Answer: D

Question 4

You are using the SOAP connector API to process an XML payload. Which task should you perform to bypass the JSON/XML translator in the SOAP connector API that you are calling from custom code when making a POST call?

A. Set the Accept header to application/xml.

B. Set the Oracle-Mobile-Payload-Type custom header to application/xml.

C. Set the Accept header to application/xml and the Content-Type header to application/xml; charset=utf-8.

D. You should use a REST connector instead because the translator cannot be bypassed.

E. Set the Content- header to application/xml; charset=utf-8.

Correct Answer: C

Question 5

The green, amber, and red traffic light indicators on the MCS Environments and Diagnostics pages depict the overall health of an environment for the last minute MCS bases this at-a-glance view on the health metrics for the environment. When die error count and request/response times exceed configured thresholds, the traffic light indicator changes from green (normal) to amber (adverse) or red (severe).
For your development environment, you expect more errors to occur and thus want to increase thresholds for when the light indicator changes. How would you change the threshold for error counts to allow more errors before the traffic light indicator switches to red?

A. As an MCS administrator, add a configuration to the mobile backend application policies.

B. As an MCS administrator, download, modify, and re-upload the policy file for the environment.

C. As an MCS administrator, set the log level for a mobile backend to SEVERE to avoid performance reporting that is too fine-grained.

D. As an application developer, set the Oracle-Mobile-Diagnostic-Session-ID header value to null to indicate that error reporting is not needed for the application.

Correct Answer: C

Question 6

Which two statements are true about published MCS artifacts? (Choose two.)

A. The MCS artifacts that are marked as published can be moved to the trash.

B. The MCS artifacts that are marked as published can be deployed to different MCS environments.

C. It is possible to unpublish, edit, and republish the MCS artifacts that are marked as published.

D. It is possible to create new draft versions from the MCS artifacts that are marked as published.

Correct Answer: C,D

Question 7

An end user performs an action in a mobile app that generates an analytic event. Which option accurately describes when that analytic event is sent to MCS?

A. at a time determined by the configuration in the MCS analytics dashboard

B. when data is flushed to MCS as specified in the mobile application developer's code

C. immediately, when the analytic event occurs

D. when the user logs off

Correct Answer: C

Question 8

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. 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.

D. 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.
