Cache hit rate is calculated as hits ÷ (hits + misses) × 100. The Analytics workspace provides “Percentages & ratios”, a transformation purpose-built to derive such values from two counters and chart them over time.

B. Timeshift/Bottom N compares time periods and ranks series; it does not compute ratios.

C. Timeshift/Top N ranks highest series, not percentage calculations.

D. Chart options and metadata alter presentation only and cannot compute hit rates.

To compare memory usage by release, the engineer chooses Add Analytics → Mean (Aggregation) on plot A and selects the ‘version’ dimension in Group By. This computes separate mean values for each version (including “canary”), making it easy to see whether the canary’s average memory is lower.

A. Mean (Transformation) averages each MTS independently over time, not across dimensions.

B. The “Enter Function” free-form editor does not support an ‘A/B-1’ syntax for this task.

D. There is no “Compare Means” button in the chart UI.

In the OpenTelemetry Collector, processors sit between receivers and exporters and can transform or enrich data, including adding, removing, or modifying resource and attribute metadata before export.

B. Pipelines are only an organizational concept—lists of receivers, processors, and exporters—and perform no direct data manipulation.

C. Exporters deliver the already-processed data to back-ends; they are not intended for metadata editing.

D. Receivers solely ingest incoming telemetry and pass it on unchanged.

Splunk Observability Cloud accepts high-resolution metrics at a native granularity of 1 second, enabling fine-grained analysis without down-sampling.

A. 2-second resolution data is accepted but is not the maximum native granularity.

B. 15 seconds corresponds to medium-resolution metrics, not high-resolution.

D. 5 seconds is supported, yet higher (1 second) resolution is still possible, making 5 seconds not the highest.

In Splunk Observability Cloud, subscribing to a detector means choosing to be notified—by email, Slack, webhook, etc.—whenever that detector’s alert condition fires. Subscription does not change detector logic, modify data, or let the user edit alert parameters; it simply delivers notifications to the subscriber.

A. Root-cause analysis is done with charts or Related Content, not by subscribing.

B. Data transformations are configured in detector rules, not through subscription.

D. Editing alert parameters requires “Edit” privileges on the detector, not a subscription.

Visual interpretation of a chart is influenced by how raw data is sampled (chart resolution), by automatic rollups that down-sample or summarize the series, and by any analytics functions (e.g., rate, percentile) applied in the plot. Tags are merely labels and don’t alter the plotted numeric values.

A. Tags classify or filter series but don’t change the values rendered in the chart.

A Dashboard Group is a container for one or more dashboards. When you share the group with “Everyone” (or a specific team such as SRE) every dashboard—and therefore every chart—in that group becomes immediately visible to all members, letting you distribute a whole collection at once.

B. Shared charts expose only a single chart, not a collection.

C. Public dashboards share one dashboard externally; they don’t bundle multiple dashboards for internal teams.

D. Chart exporter creates static files (PNG/CSV); it doesn’t provide in-product sharing.

Creating a detector in Splunk Observability involves:

1) selecting the Alert Signal (metric or event stream),

2) defining the Alert Condition (threshold, absence, etc.) and related Alert Settings (severity, window),

3) composing the Alert Message, and

4) designating Alert Recipients. These five elements map directly to option C.

A. Uses “Alert Status”; detectors are built from a signal, not a pre-existing status.

B. “Alert Criteria” is imprecise; docs use “Condition”.

D. “Alert Meaning” is not a configuration item; “Signal” is missing.

Cloning creates an independent copy of an existing detector. This lets you experiment with rule changes or notification settings and examine how the detector was built, all without impacting the original detector or its recipients.

B. Billing for TAPM is unaffected; cloning does not alter data volume.

C. Additional recipients can be added directly in the original detector; cloning is unnecessary for that.

1. Splunk Observability Cloud Docs → Alerts & Detectors → “Clone a detector”, ¶1-3 (docs.splunk.com/Observability/latest/monitor/clone-detector.html).

2. Splunk Observability Cloud Docs → Billing FAQ, “What counts toward TAPM?”, confirms cloning has no effect.

The chart builder lets you assign a different visualization to each individual plot, but this capability is limited to Line, Area, and Column chart types.

A. Bar charts don’t support per-plot style selection.

B. Bar charts cannot mix plot styles; Area and Column can.

D. Histogram charts allow only histogram rendering, no per-plot customization.
