Linux Foundation Prometheus Certified Associate Exam Sample Questions (Q58-Q63):

NEW QUESTION # 58
What is the best way to expose a timestamp from your application?

A. With a constant metric of value 1 and the timestamp as metric timestamp.
B. With a constant metric of value 1 and the timestamp as label.
C. With a counter that is increased to the correct value.
D. With a gauge that has the timestamp as value.

Answer: D

Explanation:
The correct way to expose a timestamp from an application in Prometheus is to use a gauge metric where the timestamp value (in Unix time, seconds since epoch) is stored as the metric's value. This approach aligns with the Prometheus data model, which discourages embedding timestamps as labels or metadata.
Example:
app_last_successful_backup_timestamp_seconds 1.696358e+09
In this example, the gauge represents the timestamp of the last successful backup. The _seconds suffix indicates the unit of measurement, making the metric self-descriptive. Prometheus automatically assigns timestamps to scraped samples, so the metric's value is treated purely as data, not as a Prometheus sample time.
Options B and D are incorrect because Prometheus does not allow arbitrary timestamps or labels for time values. Option C is incorrect since counters are monotonically increasing and not suited for discrete timestamp values.

NEW QUESTION # 59
What Prometheus component would you use if targets are running behind a Firewall/NAT?

A. HA Proxy
B. Pull Proxy
C. Pull Gateway
D. PushProx

Answer: D

Explanation:
When Prometheus targets are behind firewalls or NAT and cannot be reached directly by the Prometheus server's pull mechanism, the recommended component to use is PushProx.
PushProx works by reversing the usual pull model. It consists of a PushProx Proxy (accessible by Prometheus) and PushProx Clients (running alongside the targets). The clients establish outbound connections to the proxy, which allows Prometheus to "pull" metrics indirectly. This approach bypasses network restrictions without compromising the Prometheus data model.
Unlike the Pushgateway (which is used for short-lived batch jobs, not network-isolated targets), PushProx maintains the Prometheus "pull" semantics while accommodating environments where direct scraping is impossible.

NEW QUESTION # 60
http_requests_total{verb="POST"} 30
http_requests_total{verb="GET"} 30
What is the issue with the metric family?

A. The value represents two different things across the dimensions: code and verb.
B. Metric names are missing a prefix to indicate which application is exposing the query.
C. verb label content should be normalized to lowercase.
D. Unit is missing in the http_requests_total metric name.

Answer: D

Explanation:
Prometheus metric naming best practices require that every metric name include a unit suffix that indicates the measurement type, where applicable. The unit should follow the base name, separated by an underscore, and must use base SI units (for example, _seconds, _bytes, _total, etc.).
In the case of http_requests_total, while the metric correctly includes the _total suffix-indicating it is a counter-it lacks a base unit of measurement (such as time, bytes, or duration). However, for event counters, _total is itself considered the unit, representing "total occurrences" of an event. Thus, the naming would be acceptable in strict Prometheus terms, but if this metric were measuring something like duration, size, or latency, then including a specific unit would be mandatory.
However, since the question implies that the missing unit is the issue and not the label schema, the expected answer aligns with ensuring metric names convey measurable units when applicable.

NEW QUESTION # 61
What is the name of the official *nix OS kernel metrics exporter?

A. os_exporter
B. metrics_exporter
C. node_exporter
D. Prometheus_exporter

Answer: C

Explanation:
The official Prometheus exporter for collecting system-level and kernel-related metrics from Linux and other UNIX-like operating systems is the Node Exporter.
The Node Exporter exposes hardware and OS metrics including CPU load, memory usage, disk I/O, network traffic, and kernel statistics. It is designed to provide host-level observability and serves data at the default endpoint :9100/metrics in the standard Prometheus exposition text format.
This exporter is part of the official Prometheus ecosystem and is widely deployed for infrastructure monitoring. None of the other listed options (Prometheus_exporter, metrics_exporter, or os_exporter) are official components of the Prometheus project.

NEW QUESTION # 62
What is the difference between client libraries and exporters?

A. Exporters and client libraries mean the same thing.
B. Exporters expose metrics for scraping. Client libraries push metrics via Remote Write.
C. Exporters are written in Go. Client libraries are written in many languages.
D. Exporters run next to the services to monitor, and use client libraries internally.

Answer: D

Explanation:
The fundamental difference between Prometheus client libraries and exporters lies in how and where they are used.
Client libraries are integrated directly into the application's codebase. They allow developers to instrument their own code to define and expose custom metrics. Prometheus provides official client libraries for multiple languages, including Go, Java, Python, and Ruby.
Exporters, on the other hand, are standalone processes that run alongside the applications or systems they monitor. They use client libraries internally to collect and expose metrics from software that cannot be instrumented directly (e.g., operating systems, databases, or third-party services). Examples include the Node Exporter (for system metrics) and MySQL Exporter (for database metrics).
Thus, exporters are typically used for external systems, while client libraries are used for self-instrumented applications.
