Sample questions 13 of 125 shown

1. Q1 Get Metrics In with OpenTelemetry (10%)

   In the Splunk distribution of the OpenTelemetry Collector, what is the difference between agent_config.yaml and splunk-otel-collector.conf?

   1. splunk-otel-collector.conf defines the OpenTelemetry pipelines, while agent_config.yaml sets endpoint URLs and access tokens
   2. splunk-otel-collector.conf configures processors, while agent_config.yaml sets the collector's memory limits
   3. agent_config.yaml configures gateway addresses, while splunk-otel-collector.conf sets the collector's memory limits
   4. agent_config.yaml defines the OpenTelemetry pipelines, while splunk-otel-collector.conf sets endpoint URLs and access tokens

   In the Splunk distribution of the OpenTelemetry Collector, splunk-otel-collector.conf defines the OpenTelemetry pipelines (receivers, processors, exporters), while agent_config.yaml is used to configure environment-specific settings such as endpoint URLs, access tokens, and other deployment-specific configurations.
2. Q2 Get Metrics In with OpenTelemetry (10%)

   Which component of the OpenTelemetry Collector allows modification of metadata?

   1. Processors
   2. Pipelines
   3. Exporters
   4. Receivers

   Processors in the OpenTelemetry Collector are components that can modify telemetry data before it is sent to exporters. They can perform transformations such as filtering, adding, deleting, or updating attributes, tags, or resources. The attributes processor and resource processor are specifically designed for metadata modification.
3. Q3 Get Metrics In with OpenTelemetry (10%)

   A collector configuration was edited to add a hostmetrics receiver, but no host metrics are exported. Which configuration issue is most likely?

   1. The receiver was defined but not referenced in a metrics pipeline that uses the Splunk exporter
   2. The dashboard group was not renamed after the receiver was added
   3. The user forgot to create a muting rule before starting the collector
   4. The metric chart was not converted to a pie chart

   In the OpenTelemetry Collector, simply defining a receiver is not sufficient. The receiver must be referenced in a metrics pipeline within the service section of the configuration. The pipeline connects receivers, processors, and exporters, specifying the data flow path. Without the pipeline reference, the receiver is defined but never activated.
4. Q4 Get Metrics In with OpenTelemetry (10%)

   Deploy the OTel Collector on Linux. Which command is used to install the Splunk Distribution of the OpenTelemetry Collector on Linux?

   1. sudo apt-get install splunk-otel-collector
   2. curl -sSL https://dl.signalfx.com/splunk-otel-collector.sh | sh
   3. docker run splunk/otel-collector
   4. pip install splunk-otel-collector

   The Splunk Distribution of the OpenTelemetry Collector is installed on Linux using the installation script from dl.signalfx.com. The script downloads and configures the collector with the appropriate settings for the environment, including the realm and access token.
5. Q5 Get Metrics In with OpenTelemetry (10%)

   Configure the OTel Collector. Which file is the primary configuration file for the Splunk Distribution of the OpenTelemetry Collector on Linux?

   1. /etc/otel/collector/config.yaml
   2. /etc/otel/collector/agent_config.yaml
   3. /opt/splunk-otel-collector/agent_config.yaml
   4. $SPLUNK_HOME/etc/otel-collector.conf

   The primary configuration file for the Splunk Distribution of the OpenTelemetry Collector on Linux is located at /etc/otel/collector/agent_config.yaml (or /opt/splunk-otel-collector/agent_config.yaml depending on installation). This file defines the collector's receivers, processors, exporters, and service pipelines.
6. Q6 Get Metrics In with OpenTelemetry (10%)

   Edit the configuration. When modifying the OTel Collector configuration to add a new receiver, where must the receiver be added to become active?

   1. Only in the receivers section
   2. In both the receivers section and a pipeline in the service section
   3. Only in the exporters section
   4. In the extensions section

   To add a new receiver to the OpenTelemetry Collector, it must first be defined in the receivers section of the configuration, and then it must be added to a metrics (or traces/logs) pipeline in the service section. The pipeline definition connects the receiver to the appropriate processors and exporters.
7. Q7 Get Metrics In with OpenTelemetry (10%)

   Troubleshooting common errors. Which log can be checked to troubleshoot OpenTelemetry Collector issues?

   1. /var/log/splunk/otel-collector.log
   2. /var/log/messages
   3. Journalctl logs for the splunk-otel-collector service
   4. /opt/splunk-otel-collector/logs/collector.log

   On Linux systems where the Splunk Distribution of the OpenTelemetry Collector is installed as a systemd service, the primary source for troubleshooting is the journalctl logs: journalctl -u splunk-otel-collector. These logs contain collector output, errors, and warnings about configuration issues, connection problems, and data processing.
8. Q8 Get Metrics In with OpenTelemetry (10%)

   General OpenTelemetry Concepts. What is OpenTelemetry?

   1. A proprietary observability framework owned by Splunk
   2. An open-source observability framework for collecting, processing, and exporting telemetry data (metrics, traces, and logs)
   3. A commercial APM solution
   4. A database for storing time-series data

   OpenTelemetry (OTel) is an open-source observability framework under the Cloud Native Computing Foundation (CNCF). It provides APIs, SDKs, and tools for generating, collecting, processing, and exporting telemetry data including metrics, traces, and logs. It is vendor-agnostic and supported by Splunk and many other observability platforms.
9. Q9 Get Metrics In with OpenTelemetry (10%)

   What are the three main types of signals defined in the OpenTelemetry specification?

   1. Metrics, Traces, Logs
   2. Events, Metrics, Traces
   3. Logs, Events, Alerts
   4. Metrics, Alerts, Dashboards

   The OpenTelemetry specification defines three primary signal types: Metrics (measurements about system performance), Traces (records of the execution path of requests through distributed systems), and Logs (timestamped text records of events). Together they provide comprehensive observability.
10. Q10 Get Metrics In with OpenTelemetry (10%)

    What is the role of the OTel Collector gateway mode?

    1. To collect data from a single host and send directly to the backend
    2. To act as a centralized intermediary that receives data from multiple agent collectors, processes it, and forwards it to the backend
    3. To replace the need for any agents on individual hosts
    4. To store metrics locally for historical analysis

    In gateway mode, the OpenTelemetry Collector acts as a centralized intermediary (gateway) that receives telemetry data from multiple agent collectors deployed on individual hosts. It can perform centralized processing, filtering, and batching before forwarding data to the Splunk Observability Cloud backend.
11. Q11 Get Metrics In with OpenTelemetry (10%)

    What is the role of the OTel Collector agent mode?

    1. To collect data from a single host and send it directly to the backend or to a gateway collector
    2. To act as a centralized data processing hub
    3. To replace existing monitoring agents entirely
    4. To store telemetry data for compliance purposes

    In agent mode, the OpenTelemetry Collector runs on each individual host and collects telemetry data locally. It sends the data directly to the Splunk Observability Cloud backend or to a gateway collector for centralized processing. Agent mode is the most common deployment pattern.
12. Q12 Get Metrics In with OpenTelemetry (10%)

    Which receiver in the OpenTelemetry Collector is used to collect host-level metrics such as CPU, memory, and disk usage?

    1. hostmetrics receiver
    2. kubeletstats receiver
    3. prometheus receiver
    4. filelog receiver

    The hostmetrics receiver in the OpenTelemetry Collector is specifically designed to collect host-level metrics including CPU utilization, memory usage, disk I/O, network traffic, and filesystem usage. It is one of the most commonly used receivers for infrastructure monitoring.
13. Q13 Get Metrics In with OpenTelemetry (10%)

    What is required to authenticate the OpenTelemetry Collector with Splunk Observability Cloud?

    1. A username and password
    2. An API access token
    3. An SSL certificate
    4. A Splunk license key

    The OpenTelemetry Collector authenticates with Splunk Observability Cloud using an API access token (also called a SignalFx access token). This token is configured in the exporter settings within the collector configuration and identifies the organization account that the data should be sent to.
