Free Nomad Associate sample questions

1. A team wants to deploy a background worker that processes queue items continuously. If the process crashes, Nomad should automatically restart it. Which job type is the most appropriate for this scenario?

   • A. Service job type
   • B. Batch job type
   • C. System job type
   • D. Periodic job type
   Show answer

   Correct: A. The 'service' job type is designed for long-running processes that should never exit voluntarily. If a service task exits, Nomad considers it a failure and will attempt to restart it. Batch is for short-lived tasks, and system is for node-level agents.

2. You need to ensure that a specific monitoring agent runs on every single client node in your Nomad cluster. Which Nomad job type guarantees this scheduling behavior?

   • A. Service job type
   • B. System job type
   • C. Daemon job type
   • D. Global job type
   Show answer

   Correct: B. The 'system' job type is used to schedule exactly one instance of a task group on every eligible Nomad client. This is ideal for node-level agents like monitoring tools (e.g., Prometheus Node Exporter) or log forwarders.

3. A developer needs to run a database migration script that should execute once, complete its work, and then terminate successfully without being restarted. Which job type should be used?

   • A. Batch job type
   • B. Service job type
   • C. System job type
   • D. One-shot job type
   Show answer

   Correct: A. The 'batch' job type is for short-lived tasks that are expected to terminate successfully. Nomad will not restart the task if it exits with a successful zero exit code. This is perfect for migrations or data processing scripts.

4. You want to run a batch job on a regular schedule, such as every night at midnight. Which feature in Nomad allows you to configure this behavior?

   • A. The periodic stanza within a batch job
   • B. A cron job type in the job specification
   • C. The scheduled stanza within a service job
   • D. A system job with a interval property
   Show answer

   Correct: A. Nomad supports scheduling tasks based on a cron expression using the 'periodic' stanza. This stanza is only valid for 'batch' jobs and tells Nomad to instantiate the batch job on the defined schedule.

5. Your infrastructure has some nodes with SSDs and some with HDDs. You want your database job to preferably run on SSD nodes, but it can run on HDD nodes if no SSD nodes are available. Which Nomad feature should you use?

   • A. The constraint stanza
   • B. The affinity stanza
   • C. The placement stanza
   • D. The require stanza
   Show answer

   Correct: B. The 'affinity' stanza expresses a preference for where a task group should run based on node attributes or metadata. It calculates a score, so it prefers nodes that match but will schedule elsewhere if necessary. The 'constraint' stanza is a hard requirement.
