Answer: A,E
NEW QUESTION # 111
A custom cartridge that seemed to be performing well in a sandbox has been installed in production. The production instance is showing increased page load times that seem to be related to the new custom code.
What can a developer do to quickly track down the potential problem?
Answer: C
Explanation:
Because the performance degradation occurs specifically underproduction traffic and production conditions, Code Profiler should collect execution data from that environment. Development Mode records all requests with greater detail than the normal aggregated Production Mode, making it suitable for a short, focused diagnostic period.
Salesforce explains that when the Code Profiler mode is changed, existing results are flushed. In a production instance with sufficient real traffic, the administrator can wait for the problematic behavior to occur again and then refresh the profiler results.
Option B changes the mode but does not allow time for new requests to generate useful profiling data. Option C profiles a sandbox and may fail to reproduce the production-specific load characteristics. Extended Script Development Mode also carriessevere performance implications, so Salesforce recommends using it with particular caution in production scenarios.
Once data is collected, developers can inspect controller, script, API, template, and request timing to isolate the expensive custom execution path.
Study Guide reference:Application Development - Code Profiler, Development Mode, production performance diagnostics, controller/script profiling, and performance troubleshooting.
NEW QUESTION # 112
A developer working on a simple web service integration is asked to add appropriate logging to allow future troubleshooting.
According to logging best practices, which code should the developer write to log when an operation succeeds, but has an unexpected outcome that may produce side effects?
Answer: A
Explanation:
WARNis the appropriate severity because the operation technically succeeded, yet the result is abnormal enough to require attention and could produce undesirable side effects. A warning signals a recoverable or unexpected condition without incorrectly classifying the operation as an outright failure.
Salesforce logging guidance identifies custom WARN logs as appropriate for warnings in application areas such as integrations and payment processing that can impact users. WARN messages are also available under normal production logging configurations, making them suitable for operational conditions that administrators should be able to investigate.
DEBUG is intended for detailed development/troubleshooting information and is disabled for persistent production logging by default. It would therefore understate a potentially consequential condition. ERROR should represent an operation or state that actually failed or cannot be processed successfully; the question explicitly states that the operation succeeded.
Using the correct severity improves alerting, log filtering, and incident analysis while preventing routine recoverable situations from being mistaken for application failures.
Study Guide reference:Application Development -dw.system.Logger, WARN/DEBUG/ERROR severity, Service Framework troubleshooting, and operational logging practices.
NEW QUESTION # 113
A developer is working on a new feature that requires the use of a custom script. What is the first step the developer should take?
Answer: B
Explanation:
Custom storefront scripts arecode artifacts, not Business Manager metadata objects. Consequently, among the supplied options, B is the technically correct first step: create or define the required JavaScript/CommonJS script module within the project code structure.
Salesforce documents that B2C Commerce script modules are.js,.ds, or.jsonfiles and are normally stored in cartridges, commonly undercartridge/scripts. Modules expose public functionality throughexportsand are loaded withrequire(). Controllers and other server-side components can then import and invoke that reusable module.
Business Manager does not provide a general mechanism for creating arbitrary SFRA application scripts.
Business Manager manages configuration, metadata, jobs, services, catalogs, and related platform data; deployable application logic belongs in cartridges/code versions.
Option C is less precise because the script/module itself must first be established in the codebase before its exported behavior can be consumed.
Study Guide reference:Application Development - CommonJS modules,cartridge/scripts, JavaScript modules,require(), exports, and cartridge-based application code.
