A developer must troubleshoot to pinpoint the causes of performance issues when a custom page loads in their org. Which tool should the developer use to troubleshoot?
Correct Answer: D
The Developer Console is a tool that allows developers to access and edit code, execute SOQL and SOSL queries, debug and test code, view logs and performance data, and more. The Developer Console can help troubleshoot performance issues by providing information such as execution time, heap size, CPU time, and limits usage for each line of code. The Developer Console also has features such as the Performance Tree, the Execution Overview, and the Timeline View that can help identify and optimize the performance bottlenecks.
The Developer Console is different from the other tools listed, as they are not designed for performance troubleshooting. AppExchange is a marketplace for Salesforce apps and components. Salesforce CLI is a command-line interface for managing Salesforce projects and orgs. Visual Studio Code IDE is an integrated development environment that supports Salesforce extensions and tools.
