Question 1 Domain 2 HarmonyOS Application Development

A developer needs to cancel a task, but part of the code segment he wrote was deleted by mistake. The remaining codes are as follows, with the missing codes indicated by the dash:

TaskDispatcher dispatcher =

getUlTaskDispatcher();

Revocable revocable =

________________________(new Runnable(){

@Overide Public void run(){

HiLog.info(L . ABEL_ _LOG,"delay dispatch");

}

},10);

Boolean revoked = revocable.revoke();

HiL og.info(L _ABEL_ LOG),"%{public}b" ,revoked);

Which of the following might be missing pieces in the above code?

Correct Answer A
Explanation Particle Abilities (PA) are lightweight, UI-less service components in HarmonyOS. When designing a PA application, developers must follow the standard development process: create the application structure, write the service logic, configure permissions and capabilities, and test the application. Designing an interface can be omitted because PAs do not provide a visual user interface. They run in the background and provide services or perform tasks without user interaction.

Question 2 Domain 3 UI Development

When developing a HarmonyOS application, if you want to set the background color for a Text component in the page, the following is correct

Correct Answer A, B, C, D
Explanation State decorators in HarmonyOS ArkUI manage component state variables. The @State decorator manages internal component state that triggers UI updates when changed. The @Link decorator creates a two-way binding to a parent component's state variable. Both decorators enable reactive data management in custom components. Other decorators like @Prop create one-way binding, and @Provide/@Consume handle cross-level state sharing, but @State and @Link are the primary state management decorators.

Question 3 Domain 2 HarmonyOS Application Development

When a developer is developing a smart home application, the Switch component will be used to represent the switch of some devices, and ON should be displayed on the ON status component and OFF should be displayed on the closed state component, what are the following options that can meet the requirements?

Correct Answer A, D
Explanation Non-sensitive permissions declared in config.json are automatically granted during installation without requiring user interaction. Sensitive permissions, however, must be requested at runtime and approved by the user while the app is running. This distinction reflects HarmonyOS's permission model where lower-risk permissions are pre-authorized and high-risk permissions require explicit user consent during execution.

Question 4 Domain 1 HarmonyOS Fundamentals

In the distributed terminal scenario, only by ensuring that the equipment used by the user is safe and reliable can the user's data be effectively protected on the virtual terminal and avoid the leakage of user privacy. What does HarmonyOS do to ensure that your devices are reliable?

Correct Answer A, B, C
Explanation Decoding is the process of converting encoded information back into its original usable form. When a photo is taken and converted to digital form, that is the encoding process, not decoding. Decoding would involve taking that digital file and converting it back into viewable information, such as displaying it on a screen or converting it to a printable format. Saving the photo in digital form is part of storage, not the decoding operation.

Question 5 Domain 3 UI Development

Which of the following items belongs to the kernel layer in the system architecture of HarmonyOS?

Correct Answer A, B, C, D
Explanation The Kernel Abstract Layer (KAL) is a fundamental component of HarmonyOS architecture that provides abstraction between the kernel and upper layers. Its purpose is to shield the differences and complexities of multiple processor cores and architectures from the application layer above. This allows applications to run consistently across different hardware without needing core-specific code.

Question 6 Domain 2 HarmonyOS Application Development

In a HarmonyOS application, there must be one and only one HAP of the feature type.

Correct Answer B
Explanation In distributed terminal scenarios, security and reliability depend on hardware and software protections. Device Certificate Certification validates device identity and authenticity. Trusted Execution Environment (TEE) provides an isolated secure area for sensitive operations. Secure Boot ensures only authorized code runs during startup. These three mechanisms work together to establish device trust. The other options either don't exist in this context or don't address the specific security needs of distributed scenarios where multiple devices interact and share data.

Question 7 Domain 2 HarmonyOS Application Development

Which of the following statements is true about the use of the previewer?

Correct Answer A, B, C, D
Explanation When setting up the HarmonyOS development environment, Gradle and NPM agents are configuration tools for managing dependencies and packages. If your network has direct internet access, you can typically access package repositories without needing to configure proxy agents. Agents are necessary only when network access is restricted or filtered. Since the scenario states the network can directly access the internet, configuring agents is not required for the development environment to function correctly.
