Linux Foundation Prometheus Certified Associate Exam Sample Questions (Q14-Q19):NEW QUESTION # 14
Which Alertmanager feature prevents duplicate notifications from being sent?
  • A. Grouping
  • B. Inhibition
  • C. Deduplication
  • D. Silencing
Answer: C
Explanation:
Deduplication in Alertmanager ensures that identical alerts from multiple Prometheus servers or rule evaluations do not trigger duplicate notifications.
Alertmanager compares alerts based on their labels and fingerprints; if an alert with identical labels already exists, it merges or refreshes the existing one instead of creating a new notification.
This mechanism is essential in high-availability setups where multiple Prometheus instances monitor the same targets.

NEW QUESTION # 15
What is the maximum number of Alertmanagers that can be added to a Prometheus instance?
  • A. More than 3
  • B. 0
  • C. 1
  • D. 2
Answer: A
Explanation:
Prometheus supports integration with multiple Alertmanager instances for redundancy and high availability. The alerting section of the Prometheus configuration file (prometheus.yml) allows specifying a list of Alertmanager targets, enabling Prometheus to send alerts to several Alertmanager nodes simultaneously.
There is no hard-coded limit on the number of Alertmanagers that can be added. The typical best practice is to run a minimum of three Alertmanagers in a clustered setup to achieve fault tolerance and ensure reliable alert delivery, but Prometheus can be configured with more than three if desired.
Each Alertmanager node in the cluster communicates state information (active, silenced, inhibited alerts) with its peers to maintain consistency.
Reference:
Verified from Prometheus documentation - Alertmanager Integration, High Availability Setup, and Prometheus Configuration - alerting Section.

NEW QUESTION # 16
How would you correctly name a metric that provides metadata information about the binary?
  • A. app_metadata
  • B. app_build
  • C. app_build_info
  • D. app_build_desc
Answer: C
Explanation:
The Prometheus naming convention for metrics that expose build or version information about an application binary uses the _info suffix. The standard pattern is:
<application>_build_info
This metric typically includes constant labels such as version, revision, branch, and goversion to describe the build environment.
For example:
app_build_info{version="1.2.3", revision="abc123", goversion="go1.22"} 1 This approach follows the official Prometheus instrumentation guidelines, where metrics ending in _info convey metadata or constant characteristics about the running process.
The other options do not conform to the Prometheus best practice of suffix-based semantic naming.

NEW QUESTION # 17
How do you calculate the average request duration during the last 5 minutes from a histogram or summary called http_request_duration_seconds?
  • A. rate(http_request_duration_seconds_sum[5m]) / rate(http_request_duration_seconds_average[5m])
  • B. rate(http_request_duration_seconds_total[5m]) / rate(http_request_duration_seconds_average[5m])
  • C. rate(http_request_duration_seconds_total[5m]) / rate(http_request_duration_second$_count[5m])
  • D. rate(http_request_duration_seconds_sum[5m]) / rate(http_request_duration_seconds_count[5m])
Answer: D
Explanation:
In Prometheus, histograms and summaries expose metrics with _sum and _count suffixes to represent total accumulated values and sample counts, respectively. To compute the average request duration over a given time window (for example, 5 minutes), you divide the rate of increase of _sum by the rate of increase of _count:
        ext{Average duration} = rac{        ext{rate(http_request_duration_seconds_sum[5m])}}{        ext{rate(http_request_duration_seconds_count[5m])}} Here,
http_request_duration_seconds_sum represents the total accumulated request time, and
http_request_duration_seconds_count represents the number of requests observed.
By dividing these rates, you obtain the average request duration per request over the specified time range.

NEW QUESTION # 18
What is the role of the Pushgateway in Prometheus?
  • A. To scrape short-lived targets directly.
  • B. To store metrics long-term for historical analysis.
  • C. To receive metrics pushed by short-lived batch jobs for later scraping by Prometheus.
  • D. To visualize metrics in Grafana.
Answer: C
Explanation:
The Pushgateway is a Prometheus component used to handle short-lived batch jobs that cannot be scraped directly. These jobs push their metrics to the Pushgateway, which then exposes them for Prometheus to scrape.
This ensures metrics persist beyond the job's lifetime. However, it's not designed for continuously running services, as metrics in the Pushgateway remain static until replaced.
