최신 Salesforce Developer Comm-Dev-101 무료샘플문제 (Q121-Q126):

질문 # 121
What step should a developer take to troubleshoot code changes not appearing on the Storefront?

A. Check that the correct code version is selected.
B. Check that the search index was recently rebuilt.
C. Check the Business Manager site cartridge path.

정답：A

설명：
B2C Commerce can store multiple code versions simultaneously, but only theactive code versionsupplies the storefront ' s templates, controllers, scripts, and static code resources. If recently uploaded cartridge changes do not appear, verifying that the expected code version is active is therefore a fundamental troubleshooting step.
Salesforce ' s Code Deployment documentation states that all templates, pipelines, scripts, and images are taken from the active version. It also specifically recommends checking that the cartridge was uploaded to the current code version when storefront changes do not appear. Salesforce ' s SFRA troubleshooting guidance further recommends switching code versions and reactivating the intended version when changes are not reflected on the server.
A search-index rebuild is relevant to indexed product, category, content, or search configuration-not to changes in JavaScript controllers or ISML templates. Cartridge-path configuration should also be verified, but the source ' s earlier scenario already uses that check before checking the active version.
Study Guide reference:B2C Commerce Setup - Code Deployment, active code versions, cartridge deployment, storefront troubleshooting, and version activation.

질문 # 122
A Digital Developer is inspecting the weekly service status report for a critical internally-hosted web service used in the application and notices that there are too many instances of unavailability.
Which two solutions are possible options to reduce the unavailability of the service? (Choose two.)

A. Modify the code that makes the request to the external service to be wrapped in a try / catch block.
B. Increase the web service time out.
C. Update the external service to have a faster response time.
D. Change the code that makes the request to set the throwOnError attribute, of the service, to be true.

정답：A,C

질문 # 123
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?

A. Logger.error( ' Unexpected service response. ' )
B. Logger.warn( ' Unexpected service response. ' )
C. Logger.debug( ' Unexpected service response. ' )

정답：B

설명：
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.

질문 # 124
A developer is tasked with the development of a new Page Designer Page Type, as requested by the merchant.
How should they define the rendering logic of the page?

A. Implement a Controller file with a " render " route.
B. Implement a metadata JSON file with a " render " property.
C. Implement a JavaScript file with a render() function.

정답：C

설명：
A Page Designer Page Type consists of a metadata definition plus a corresponding JavaScript implementation. The rendering behavior itself belongs in the page-typeJavaScript file, which must expose arender()function.
Salesforce states that the script file must have the same base name and location as the Page Designer meta- definition file, using.jsrather than.json. The script ' srenderfunction receives aPageScriptContextand must return the resulting markup as a string. It commonly renders an ISML template usingdw.util.Template, and the template can in turn render the page ' s regions.
The metadata JSON describes the Page Type ' s declarative configuration-such as its attributes and regions- but does not implement rendering through a " render " property. A conventional SFRA controller route can invokePageMgr.renderPage()to initiate rendering, but that controller does not define the actual Page Type rendering logic.
This separation allows Page Designer to manage page composition while the JavaScript implementation controls the output representation.
Study Guide reference:Application Development - Page Designer Page Types, page metadata,render() functions,PageScriptContext, and Page Designer rendering.

질문 # 125
A Digital Developer has detected storefront pages being rendered with an error message. After inspecting the log files, the Developer discovered that an enforced quota is being exceeded.

A. Rewrite the code that is causing the overage.
B. Change the Business Manager configuration for the quota settings.
C. Ask support to remove the quota limit.
D. Take no action, the overage will be resolved when concurrent visitors are reduced.

정답：B
