Google ACE Practice Question: Ensuring Successful Operation of a Cloud Solution

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Create an uptime check

  Why it's wrong here

  Creating an uptime check is a monitoring feature that periodically probes a URL or service to verify availability and response time, generating alert conditions and metrics. While uptime check metrics can be added to a dashboard for visibility, creating one is not a step in building a dashboard for an existing metric—it's a separate health-check action that requires a target resource and alerting configuration.

• ✓

  Add the chart to a dashboard

  Why this is correct

  After you generate a chart in Metric Explorer, adding it to a dashboard persists the visualization as a widget in a chosen layout, making it visible to the team and available in the Monitoring UI. This is the final, required step to actually place the metric on the dashboard; without it, the chart exists only in the temporary Metric Explorer session and will be lost when you navigate away.

• ✓

  Create a chart using Metric Explorer

  Why this is correct

  Creating a chart using Metric Explorer is the initial step where you select a metric, apply aggregation, filter by labels, and set a time range to preview the data as a graph. This action builds the chart definition, but it only exists temporarily until you save it; you must explicitly add it to a dashboard to make it persistent and shareable, so it's a necessary but not sufficient condition for the overall task.

• ✗

  Create a log-based metric

  Why it's wrong here

  Creating a log-based metric extracts quantitative values from log entries by defining a filter or a counter, converting unstructured logs into a custom metric. This is an advanced technique for generating new metrics from logs; it is not required when the engineer needs to display an already available Cloud Monitoring metric on a dashboard, nor does it directly contribute to dashboard layout or widgets.

• ✗

  Set up a notification channel

  Why it's wrong here

  Setting up a notification channel configures how alerting policies deliver alerts—for instance, via email, SMS, or PagerDuty—and is entirely unrelated to dashboard visualization. Dashboards are read-only displays of metrics; they do not send notifications, and no notification channel is involved in the process of adding a chart to a dashboard, so this action would be superfluous for the stated goal.
