Right Answer:
In ARM Compiler, you use preprocessor directives by starting a line with a `#` symbol. Common directives include `#define` to create macros, `#include` to include header files, and `#ifdef`/`#ifndef` for conditional compilation. For example:

```c
#define MAX_SIZE 100

#include "myheader.h"

#ifdef DEBUG
// Debugging code here
#endif
```

Right Answer:
To implement custom workflows in AEM, follow these steps:

1. **Create a Workflow Model**: Use the AEM Workflow Model Editor to design your workflow. Define the steps and the order in which they will execute.

2. **Add Workflow Steps**: Include custom workflow processes by creating Java classes that extend `WorkflowProcess`. Implement the `execute` method to define the logic for each step.

3. **Register the Workflow Process**: Use the OSGi configuration to register your custom workflow process in AEM.

4. **Create a Workflow Launchers**: Set up workflow launchers to trigger the workflow based on specific events or conditions, such as content creation or modification.

5. **Test the Workflow**: Deploy your workflow and test it to ensure it functions as expected.

6. **Monitor and Debug**: Use the AEM Workflow console to monitor the execution and debug any issues that arise.

Right Answer:
The RTE (Runtime Environment) handles client-server communication by using a defined interface that allows client applications to request services from server applications. It manages the communication through the use of ports, where the client sends requests via a request port and the server responds through a response port. The RTE ensures that the data is correctly marshaled and unmarshaled between the client and server, facilitating seamless interaction while adhering to the AUTOSAR standards.

Right Answer:
RTE ensures data consistency in communication by using a combination of mechanisms such as data versioning, synchronization points, and the use of consistent data types. It manages the timing of data updates and ensures that all components access the most recent and valid data through the use of a reliable communication protocol and by maintaining a consistent state across the system.

Right Answer:
To switch between ARM and Thumb modes in code, use the `BX` instruction with the least significant bit (LSB) set to 1 for Thumb mode and 0 for ARM mode. For example, to switch to Thumb mode, use `BX Rn` where `Rn` contains an address with the LSB set to 1. To switch back to ARM mode, use an address with the LSB set to 0.
