80 Metapercept Technology Services Interview Questions and Answers

20 common asked question in every interview

Ques:- How do you test and debug RTE-generated interfaces

Asked In :- Manipal Technologies, Big Rattle Technologies, First Zen, Barracuda Networks, Black and White Business Solutions, Diya Systems (Mangalore), Maruti Techlabs, Stridely Solutions, chetu, FIN Infocom,

Right Answer:
To test and debug RTE-generated interfaces, you can follow these steps:

1. **Use RTE Trace Tools**: Enable tracing in the RTE to log communication between components.
2. **Check Configuration**: Verify the RTE configuration files for correct settings and mappings.
3. **Simulate Components**: Use simulation tools to test the behavior of software components in isolation.
4. **Unit Testing**: Implement unit tests for individual components to ensure they interact correctly with the RTE.
5. **Integration Testing**: Test the complete system to check the interactions between all components through the RTE.
6. **Debugging Tools**: Utilize debugging tools (like debuggers or IDEs) to step through the code and monitor RTE behavior during execution.
7. **Error Handling**: Implement and test error handling mechanisms to ensure robustness in communication failures.

By systematically applying these methods, you can effectively test and debug RTE-generated interfaces.

Aem Developer

Ques:- How do you implement user permissions and access control in AEM

Asked In :- Fission Infotech, MBR Informatics, MMF INFOTECH, Vestas Wind Technology India, WebReinvent Technologies, ISG NovaSoft Technologies, Anlage Infotech (I), Onward Technologies, ScriptsHub Technologies, PRORIGO SOFTWARE PVT,

Right Answer:
In AEM, user permissions and access control are implemented using the Apache Jackrabbit Oak security model. You can manage user permissions by creating user groups and assigning specific permissions to these groups through the AEM User Administration interface. Additionally, you can set access control lists (ACLs) on nodes in the JCR repository to define what users or groups can read, write, or modify content. This can be done using the AEM console or programmatically via the Sling API or JCR API.

AUTOSAR

Ques:- How does Adaptive AUTOSAR support high-performance computing and service-oriented architecture

Asked In :- Define Labs, RAKUTEN INDIA ENTERPRISE PVT, Happiest Minds Technologies Pvt., Softcell Technologies, Evolvus Solutions, Clicks Bazaar Technologies, Arya Omnitalk Wireless Solutions, Invendis Technologies India, Nippon Data Systems, Cotelligent India,

Right Answer:
Adaptive AUTOSAR supports high-performance computing and service-oriented architecture by providing a flexible framework that allows for the deployment of applications on powerful hardware platforms. It utilizes a service-oriented architecture (SOA) that enables communication between distributed components through well-defined interfaces, facilitating the integration of complex applications and services. This architecture supports dynamic deployment and scalability, allowing for efficient resource management and high-performance processing in automotive systems.

AUTOSAR RTE Development

Ques:- How is memory mapping handled in RTE generated code

Asked In :- Walkover Web Solutions, QuickXpert Infotech, XIPHIAS Software Technologies, New Vision Info Tech, Valethi, Evince Development, Hinduja Tech, JNET Technologies, Rightpoint India Digital, Cimpress India,

Right Answer:
Memory mapping in RTE generated code is handled through the configuration of the RTE memory layout, which defines the memory regions for different components. The RTE uses a memory mapping file to allocate memory for application software components, ensuring that each component has its own address space and that communication between components is managed efficiently through the RTE. This mapping is typically defined in the AUTOSAR XML files and is used during code generation to create the appropriate memory access functions.

.Net Team Lead/ Tech Lead

Ques:- Consider a scenario where lots of objects are created in runtime and soon after the execution starts, you have millions of objects consuming 90% of JVM memory. What would you do about it?

Asked In :- Atidan Technologies, Metapercept Technology Services, Futurenet Technologies (India),

Right Answer:

If millions of objects consume 90% of JVM memory shortly after startup, do the following:

Analyze Memory Usage: Use profiling tools (e.g., VisualVM, JProfiler) to find what objects are created and why.
Check for Memory Leaks: Identify if objects are unnecessarily retained (like static references or caches).
Optimize Object Creation: Reuse objects, use object pools or flyweight patterns to reduce allocations.
Tune JVM GC Settings: Adjust Garbage Collector parameters to better manage memory and pause times.
Use Efficient Data Structures: Choose memory-efficient collections and data types.
Consider Off-heap Memory: For large caches, use off-heap solutions like direct byte buffers or external caches.
