83. How Does Handle An AI API Failure?

Ans:

• The Application Should Detect API Errors, Timeouts, And Rate-Limit Responses Without Crashing The Entire Workflow. 
• Temporary Failures Can Be Handled With Bounded Retries And Exponential Backoff. A Circuit Breaker Or Suitable Fallback May Help Protect Dependent Services During Extended Outages. 
• Logs Should Record Useful Diagnostic Details Without Exposing Credentials Or Sensitive User Data.

84. How Does Optimize The Cost Of A GPT-Based Application?

Ans:

Cost Optimization Begins With Measuring Token Usage, Request Volume, Latency, And The Cost Of Supporting Services. Simple Tasks Can Often Use Smaller Or Less Expensive Models If Evaluation Confirms Acceptable Quality. Prompt Length, Retrieval Context, Output Limits, And Repeated Requests Can Also Be Optimized. Caching And Batching May Reduce Repeated Work Where They Fit The Use Case.

85. How Does Protect Confidential Data In An AI Project?

Ans:

Confidential Data Should Be Classified Before Deciding Which AI Services And Processing Locations Are Approved. The Application Should Minimize Data Collection And Mask Sensitive Fields Whenever Possible. Encryption, Least-Privilege Access, Secure Secrets Management, And Appropriate Retention Controls Help Protect Information. External Model Providers Must Be Evaluated Against Organizational Policies And Contractual Requirements.

86. Explain A Complex AI Concept To A Non-Technical Client?

Ans:

• The Explanation Should Begin With The Business Problem And The Outcome The AI Solution Is Intended To Deliver. 
• Technical Concepts Can Be Translated Into Simple Examples, Diagrams, Or Comparisons Relevant To The Client’s Work. 
• Benefits, Limitations, Risks, And Costs Should Be Described In Clear Language.

87. Describe An AI Project Suitable For A Fresher Portfolio.

Ans:

A Document Question-Answering Assistant Is A Practical Project For Demonstrating Generative AI Skills. The Application Can Accept Documents, Split Them Into Chunks, Generate Embeddings, And Retrieve Relevant Sections. A Language Model Can Use Those Sections To Answer Questions And Provide Supporting References. Python, A Vector Store, An AI API, And A Simple Web Interface Can Form The Main Technology Stack.

88. What Skills Are Important For An Accenture AI Developer Fresher?

Ans:

Important Skills Include Python Programming, Data Structures, Algorithms, SQL, And Basic Software Engineering. Knowledge Of Machine Learning, NLP, Transformers, Prompt Engineering, And RAG Provides A Useful AI Foundation. API Integration, Git, Cloud Basics, Testing, And Debugging Support Application Development. Communication, Teamwork, Adaptability, And Analytical Thinking Are Also Valuable In Client-Facing Projects.

89. How Should A Fresher Prepare For An Accenture AI Developer Interview?

Ans:

Preparation Should Begin With Programming Fundamentals, Python, SQL, Object-Oriented Programming, And Basic Problem-Solving Exercises. Core AI Topics Should Include Machine Learning, Neural Networks, LLMs, Prompt Engineering, Embeddings, And RAG. Reviewing Projects In Detail Helps Prepare For Questions About Architecture, Challenges, Testing, And Results.

90. Why Should Accenture Hire As An AI Developer Fresher?

Ans:

A Strong Candidate Can Demonstrate Programming Fundamentals, A Genuine Interest In Artificial Intelligence, And A Willingness To Learn New Technologies. Practical Projects Can Show The Ability To Apply Concepts Such As Python, APIs, Data Processing, And Language Models To Real Problems. Analytical Thinking And Structured Debugging Help Address Technical Challenges Effectively.
