Skills Being MeasuredThis exam measures your ability to accomplish the technical tasks listed below.The percentages indicate the relative weight of each major topic area on the exam.The higher the percentage, the more questions you are likely to see on that content area on the exam. The information after “This objective may include but is not limited to” is intended to further define or scope the objective by describing the types of skills and topics that may be tested for the objective. However, it is not an exhaustive list of skills and topics that could be included on the exam for a given skill area. You may be tested on other skills and topics related to the objective that are not explicitly listed here.

Develop Windows Store Apps (17%) Create background tasks. This objective may include but is not limited to: implement the Windows.applicationmodel.background classes; implement the IBackgroundTask interface Consume background tasks. This objective may include but is not limited to: use timing and system triggers; keep communication channels open; request lock screen access; use the BackgroundTransfer class to finish downloads Create and consume WinMD components. This objective may include but is not limited to: create a WinMD component in C#; consume a WinMD component; handle WinMD reference types; reference a WinMD component Discover and Interacting with Devices (16%) Capture media with the camera and microphone. This objective may include but is not limited to: use CameraCaptureUI to capture pictures or video; use MediaCapture to capture pictures, video, or audio; configure camera settings; set media formats; handle media capture events Get data from sensors. This objective may include but is not limited to: determine the availability of a sensor (Windows.devices.sensors); add sensor requests to the app manifest; handle sensor events; get sensor properties; determine location via GPS Enumerate and discover device capabilities. This objective may include but is not limited to: discover the capabilities of a device (for example, GPS, accelerometer, near field communication, and camera) Program User Interaction (17%) Implement printing by using contracts and charms. This objective may include but is not limited to: implement the Print contract; create a custom print template; construct a print preview; handle print pagination; implement in-app printing; expose printer settings within your app Implement Play To by using contracts and charms. This objective may include but is not limited to: register your app for Play To; use PlayToManager to stream media assets; register your app as a PlayToReceiver Notify users by using Windows Push Notification Service (WNS). This objective may include but is not limited to: authenticate with WNS; request, create, and save a notification channel; call and poll the WNS Enhance the User Interface (16%) Design for and implement UI responsiveness. This objective may include but is not limited to: choose an asynchronous strategy for your app; implement the Task Parallel library for multi-processor utilization; convert asynchronous operations to tasks Create animations and transitions. This objective may include but is not limited to: apply animations from the animation library; create and customize animations and transitions, including XAML transitions; implement storyboards and transformations; utilize built-in animations for controls Create custom controls. This objective may include but is not limited to: choose the appropriate base control to create a custom control template; style a control through control templates; design the control template to respond to changes in viewstate Design Windows Store apps for globalization and localization. This objective may include but is not limited to: implement .resw files to translate text; implement collation and grouping to support different reading directions; implement culture-specific formatting for dates and times Manage Data and Security (17%) Design and implement data caching. This objective may include but is not limited to: choose which types of items (user data, settings, app data) in an app should be persisted to the cache according to requirements; choose when items are cached; choose where items are cached (Windows Azure, remote storage); select the caching mechanism Save and retrieve files from the file system. This objective may include but is not limited to: handle file streams; save and retrieve files by using StorageFile and StorageFolder classes; set file extensions and associations; save and retrieve files by using the file picker classes; compress files to save space; access libraries, including pictures, documents, and videos Secure app data. This objective may include but is not limited to: encrypt data by using the Windows.Security.Cryptography namespace; enroll and request certificates; encrypt data by using certificates Prepare for a Solution Deployment (17%) Design and implement trial functionality in an app. This objective may include but is not limited to: set up a timed trial; set up a feature-based trial; set up in-app purchases; transition an app from trial to full Design for error handling. This objective may include but is not limited to: design the app so that errors and exceptions never reach the user; application class for global collection; handle device capability errors; handle asynchronous errors Design and implement a test strategy. This objective may include but is not limited to: recommend a functional test plan; implement a coded UI test; recommend a reliability test plan (performance testing, stress testing, scalability testing, duration testing); implement unit testing in an app Design a diagnostics and monitoring strategy. This objective may include but is not limited to: design profiling, tracing, performance counters, audit trails (events and information), and usage reporting; decide where to log events (local vs. centralized reporting)
