Section 4: Ensuring Successful Operation of a Cloud Solution
Section 4 is about keeping systems healthy once they are live: collecting and reading logs with Cloud Logging, building metrics, dashboards and alerts in Cloud Monitoring, tracing latency and errors with the observability tools, and using Cloud Audit Logs and Cloud Asset Inventory to answer 'who changed what, and when?'
This is the smallest of the five sections by weight, but its questions are among the most concrete on the exam. A typical item shows a symptom — an alert firing, an error spike, a missing log — and asks which tool or which log answers it fastest. The notes here focus on tool selection: which log types exist, what log-based metrics can do, how uptime checks and alerting policies fit together, and where audit trails live by default.
Two habits carry most of this section. First, know the default state of everything: audit logs that are on without configuration, log retention you get before you change anything, and which metrics a service emits for free — the exam prefers the answer that works with what Google Cloud already collects. Second, know the difference between looking at events (Logging), looking at measurements over time (Monitoring), and looking inside a single request (Trace and Error Reporting); nearly every operations question is secretly asking you to pick between those three lenses.
Study this section with the console open if you can. Create one alerting policy, build one log-based metric, and find one audit log entry for something you did yourself; the tool-selection questions become straightforward once the screens are familiar, because the wrong answers are usually tools that exist but answer a different question.
Notes pages in this section
Cloud Asset Inventory is a metadata service that gives you a searchable, historical inventory of all your Google Cloud assets across projects, folders, and the organization.
Cloud Audit Logs record who did what, where, and when across Google Cloud, providing the accountability trail for security, compliance, and troubleshooting.
Cloud Logging is the centralized, fully managed log management service that collects logs from Google Cloud resources, applications, and custom sources in near real time.
Cloud Monitoring collects metrics, events, and metadata from Google Cloud and other sources to power dashboards, alerting policies, uptime checks, and service-level objectives.
Beyond logs and metrics, Google Cloud offers three focused observability tools for application internals: Error Reporting for crashes, Cloud Trace for request latency, and Cloud Profiler for code performance.
