Thank you to everyone who participated in the Certified Meshery Contributor Certification Study Group. I hope you found the sessions engaging and valuable.

Last week, we wrapped up the unit focused on the Meshery CLI (mesheryctl). To make the session more interactive, we also worked through a sample quiz together.

    A) To store Kubernetes manifests for workloads
    B) To keep information about Meshery contexts, endpoints, and tokens
    C) To manage performance profiles
    D) To persist design patterns
  3. How does mesheryctl identify which Meshery deployment to interact with when a command is run? *

    A) A list of all clusters connected to Meshery
    B) Whether Meshery Server and adapters are running
    C) Pre-deployment and post-deployment healthchecks for Meshery
    D) Real-time performance test outputs
  8. What does the mesheryctl perf profile command show? *
