- Q11. Which approach best ensures robust automation when working with both Python scripts and no-code/low-code platforms?Only creating ad-hoc solutions without any established workflowRelying on a single monolithic Python script without any modular structureImplementing modular designs so that each component (script or workflow) can be independently updated and testedRefusing to use version control and backup solutions60s
- Q22. When creating a Streamlit application for data-driven process automation, which advanced practice is most crucial to ensure optimal performance?Avoiding the use of Streamlit features like session stateCaching frequently accessed data to reduce redundant computationRelying solely on front-end logic without any server-side optimizationStoring all data in large global variables with no memoization60s
- Q33. In terms of API security, why might OAuth be preferred over basic HTTP authentication for integrating third-party services?OAuth uses only static tokens without any expiration dateOAuth provides token-based access, reducing the need to store and transmit user credentials directlyOAuth is incompatible with RESTful APIs and only works with SOAPBasic HTTP authentication provides stronger encryption mechanisms60s
- Q44. When troubleshooting API integrations that involve JSON and XML data formats, what advanced technique can help identify subtle data structure issues?Converting all data to CSV to sidestep JSON and XML complexitiesUsing specialized schema validation tools (e.g., JSON Schema, XSD) to verify the data structureAvoiding any form of data validation, trusting the default parsingOnly relying on manual inspection of the data in a text editor60s
- Q55. A developer is tasked with optimizing a Python script that interacts with a no-code workflow. Which of the following best demonstrates advanced debugging practices?Only using print statements at every line of code to see where it slows downRelying on random guesswork to fix performance issuesIncreasing CPU resources without investigating the root causesProfiling the script to identify performance bottlenecks, then refactoring to improve efficiency60s
- Q66. How can advanced Python error handling strategies support better reliability in no-code/low-code automation?By using granular exception handling (try/except) blocks and logging to gracefully recover from unexpected conditionsBy creating custom exceptions that never get raisedBy completely avoiding exceptions and letting the application crashBy placing one broad try/except around the entire code, swallowing all errors60s
- Q77. What is an advanced method to maintain data integrity when building API integrations that connect multiple business systems?Using no validation or error handling at allImplementing two-phase commits or transactional guarantees where possible, and validating responses from each serviceOnly relying on the success status of the final request in the workflowUpdating all connected systems simultaneously without any rollback procedure60s
- Q88. In a scenario where multiple no-code/low-code platforms (e.g., Zoho Creator, OutSystems) need to share a single Python backend, which approach best handles scalability?Using ad-hoc file sharing instead of RESTful communicationHosting the backend on a single local machine without any load balancingStructuring the backend as a RESTful microservice that can scale horizontally (e.g., via containers or cloud services)Disabling concurrency to force requests to run one at a time60s
- Q99. When documenting technical solutions for future reference, which advanced documentation practice is most beneficial for large-scale process automation?Relying solely on memory and not writing any documentationWriting minimal notes on Post-it® and distributing them informallyStoring all documentation in multiple disconnected spreadsheetsCreating living documentation, such as auto-generated references from code comments and version-controlled design docs60s
- Q1010. Why is a strong understanding of RESTful APIs essential for a Python and no-code/low-code developer, beyond simple GET/POST requests?Because most no-code platforms only support SOAP, not RESTBecause RESTful APIs require extensive knowledge of hardware virtualizationBecause RESTful APIs are irrelevant to Python and no-code workflowsBecause advanced REST concepts (like HATEOAS, pagination, and versioning) are often needed for complex integrations60s
- Q1111. In creating process automation solutions, why might a developer integrate AI tools (e.g., ChatGPT) into their workflow at an advanced level?To bypass all no-code platform constraints through undocumented APIsTo generate or refine code snippets, provide guidance on troubleshooting, and speed up solution prototypingTo handle all version control tasks automatically without human interventionTo completely replace the role of the developer in building automation60s
- Q1212. Which advanced consideration is critical when using Python scripts to handle data exchange via JSON with no-code platforms?Ensuring proper encoding/decoding and verifying field structures against expected schemasConverting all JSON structures into CSV for every step of the automationAvoiding any checks on data validity, relying entirely on the no-code platformOnly processing JSON by manually parsing strings with basic methods60s
- Q1313. When using multiple no-code/low-code platforms in a single automation pipeline, which advanced best practice helps maintain consistency across different environments?Not using staging or testing environments before going liveEstablishing a well-documented interface contract (API specification) and versioning for each interactionMixing old and new versions of automation flows without any version controlHard-coding all credentials and endpoints in each workflow60s
- Q1414. For advanced debugging of concurrent Python processes that support automation tasks, which approach is most beneficial?Utilizing specialized tools like Python’s multiprocessing or threading debugging utilities, and employing concurrency-safe data structuresRelying solely on single-threaded logic and ignoring concurrency challengesLogging concurrency issues after they cause data corruptionRestricting all scripts to run sequentially, thereby eliminating concurrency altogether60s
- Q1515. In advanced scenarios, how can a developer best ensure secure handling of OAuth tokens within Python scripts and no-code workflows?Sending tokens via email to team members for conveniencePrinting token values in the logs for easier debuggingStoring tokens in encrypted storage solutions or environment variables, never hard-coding them in the sourceEmbedding tokens in plain text directly in the source code60s
