CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux DevOps engineer is instrumenting a containerized file-upload microservice that runs on the company's production Kubernetes cluster. Management has defined the following customer-facing objective: "At least 99.5 % of file-upload requests must finish within two seconds, measured over a rolling 30-day window."
Before the team can finalize the SLO, they must choose a service-level indicator (SLI) that accurately measures whether the service meets this objective. Which metric is the most appropriate SLI to use?

  • Percentage of file-upload requests that finish in ≤2 s during the last 30-day rolling window

  • 95th-percentile CPU utilization of the pods handling file-upload traffic, sampled every minute

  • Count of HTTP 5xx responses returned by the file-upload endpoint per minute

  • Number of TCP SYN packets received on port 443 for the file-upload service each minute
