Observability Concepts

Which component is strictly required to monitor batch jobs in a Prometheus ecosystem?

You are deploying Prometheus in a cluster with highly dynamic ephemeral pods. Which concern is the most significant regarding cardinality?

You notice that your Prometheus instance memory usage is growing linearly despite constant traffic. What is the most likely cause?

In the context of the Four Golden Signals, what does 'Saturation' measure?

A legacy batch job runs once per day and finishes in seconds. Why is a standard Prometheus pull model inadequate here?

A system is experiencing high latency. You need to identify if the latency is caused by external dependencies. Which of the Four Golden Signals is most relevant for this discovery?

What is the primary drawback of using the Pushgateway for long-running services?

An SRE team is transitioning from traditional logs to metrics for performance monitoring. Which scenario best justifies using metrics over logs?

What is the primary difference between a metric and a log?

Which golden signal would you monitor to detect if a specific API endpoint is returning 404s?

When configuring Service Discovery in Kubernetes, why might you use relabeling?

Why are traces considered distinct from metrics in observability?

Which monitoring philosophy is core to the Prometheus architecture?

What is the primary benefit of using a pull-based model for monitoring?

You are seeing 'Too many active series' in your Prometheus logs. Which action should be your first priority to address this?

A developer adds a 'user_id' label to an HTTP request counter. What is the operational risk?

Which of these is considered a 'counter' in Prometheus?

What is the purpose of a Gauge metric?

When designing a monitoring strategy, why should you avoid monitoring 'everything'?

What is the primary role of the 'Alertmanager'?

Why might you use an 'exporter' in Prometheus?

Which metric type would best capture the distribution of request latencies?

Why does the 'rate()' function in PromQL behave unexpectedly on counter resets?

What is the purpose of 'labels' in Prometheus?

A dashboard shows a latency spike that doesn't correlate with CPU usage. What should you investigate next?

What is 'Monitoring Philosophy' regarding alerts?

Which tool would you pair with Prometheus to visualize the collected data?

Which component is responsible for executing queries written in PromQL?

Which of the following describes the 'pull' model's benefit regarding service discovery?

You need to measure the P99 latency of your service. Which PromQL function do you use on a Histogram?

What is the primary function of the 'scrape_timeout' configuration?

How does the 'stale marker' work in Prometheus?

If you have a metric `http_requests_total` and want the increase over 5 minutes, what is the best PromQL syntax?

What is the primary goal of observability?

Why are 'logs' essential for debugging, even with perfect metrics?

When evaluating the 'Traffic' golden signal, what is the best metric to watch for a web service?

Which of these is NOT a Golden Signal?

What is the benefit of the 'service discovery' feature in Prometheus?

Which THREE items are standard techniques to reduce metric cardinality?

Which TWO of these are potential side effects of high-cardinality metrics?

Which THREE of these represent the Four Golden Signals?

Which TWO of the following are primary components of the Prometheus monitoring architecture?

Which TWO of the following are examples of metric data?

Which THREE actions are commonly performed during the 'relabeling' phase in Prometheus?

Which TWO of these are true about the 'Pull' model?

Which THREE features are provided by Grafana when used with Prometheus?

Which TWO are common causes of high-cardinality in Kubernetes environments?

Which TWO are common types of Prometheus exporters?

Which THREE are true regarding the Prometheus TSDB?

Which TWO are true about the 'Summary' metric type?

Which THREE of these are common Prometheus data sources?

Which TWO are true about Prometheus alerting rules?

Which THREE of these are recommended practices for an observability strategy?

A team is transitioning from a traditional logging system to a metrics-based monitoring approach. Which category of observability data should the team prioritize to specifically identify the 'Latency' golden signal?

You are designing a monitoring architecture for an ephemeral, auto-scaling microservices environment. Why is the Prometheus 'pull' model generally preferred over a 'push' model in this scenario?

Your team is defining Service Level Objectives (SLOs) for a web application. Which metric is most indicative of the 'Traffic' golden signal?

Which THREE of the following are considered part of the 'Four Golden Signals' of monitoring?

You are monitoring a legacy batch processing job that runs for only 30 seconds once every 24 hours. Which Prometheus component is necessary to collect these metrics?

An application is emitting logs that contain '5xx' status codes when a service is unavailable. If you want to create an alert that triggers based on the rate of these errors, what is the best practice for observability?

A developer asks why they should use Distributed Traces instead of simply using high-cardinality metrics to debug a slow request. What is the primary advantage of traces?

Which TWO statements accurately describe the differences between logs and metrics?

An engineer observes a massive spike in Prometheus memory usage after introducing a new custom label that includes a unique user ID. Which observability concept is being violated?

Which THREE factors contribute to a 'high cardinality' problem in a Prometheus environment?
