Read the first 7 Architecture & Components flashcards as text

  1. In a Cribl Stream distributed deployment, which node type manages Worker node configuration and orchestrates the cluster?

    Answer: Leader node

    The Leader node holds the authoritative configuration and pushes it to Worker nodes, while Workers handle actual data processing.

  2. What is a Cribl Stream 'Worker Group'?

    Answer: A logical grouping of Worker nodes that share the same configuration and routes

    Worker Groups allow administrators to apply a consistent set of sources, routes, pipelines, and destinations to multiple Worker nodes simultaneously.

  3. If a Cribl Stream Leader node becomes temporarily unavailable in a distributed deployment, what happens to Worker nodes?

    Answer: Worker nodes continue processing data using their last known cached configuration

    Worker nodes cache their configuration locally and continue processing data independently, making the data plane resilient to control-plane outages.

  4. Which of the following best describes Cribl.Cloud?

    Answer: A fully managed SaaS offering where Cribl operates the Leader node infrastructure

    Cribl.Cloud provides a managed control plane so organizations can use Cribl Stream without managing Leader infrastructure themselves.

  5. What is the primary purpose of Persistent Queues in Cribl Stream?

    Answer: To buffer events locally on a Worker when a destination becomes unavailable, preventing data loss

    Persistent Queues provide a disk-based buffer that absorbs backpressure and prevents event loss when downstream destinations are slow or unavailable.

  6. In Cribl Stream, which component is responsible for deciding which pipeline an incoming event is processed by?

    Answer: The Router (Routes)

    Routes evaluate filter conditions on incoming events and direct them to the appropriate pipeline, acting as the traffic director between Sources and Pipelines.

  7. What does the 'commit and deploy' workflow in Cribl Stream represent?

    Answer: Saving a configuration change and pushing it to all Worker nodes in the group

    In Cribl's GitOps model, 'commit' saves the change to version history and 'deploy' pushes the active configuration to all Worker nodes in the group.
