As part of Dress4Win's plans to migrate to the cloud, they want to be able to set up a managed logging and monitoring system so they can handle spikes in their traffic load. They want to ensure that: * The infrastructure can be notified when it needs to scale up and down to handle the ebb and flow of usage throughout the day * Their administrators are notified automatically when their application reports errors. * They can filter their aggregated logs down in order to debug one piece of the application across many hosts Which Google StackDriver features should they use?

The correct answer is Monitoring, Logging, Alerts, Error Reporting. Monitoring (Stackdriver Monitoring) is essential for observing system performance, resource utilization, and application health, which helps in understanding when to scale infrastructure up or down based on traffic patterns. Logging (Stackdriver Logging) collects and aggregates logs from all application components across many hosts, allowing administrators to filter and debug specific parts of the application. Alerts (Stackdriver Monitoring Alerts) notify administrators automatically when predefined conditions are met, such as high error rates or resource exhaustion. Error Reporting (Stackdriver Error Reporting) automatically groups and analyzes application errors, providing a centralized view and notification mechanism for application-level issues. The other options are incorrect because: "Insights" is not a standard Stackdriver product name. "Trace" (Stackdriver Trace) is used for distributed tracing and latency analysis, not primarily for general monitoring, logging, or error notification. "Debug" (Stackdriver Debugger) is for inspecting code in production, not for general logging aggregation or error reporting.
