• Question 116:

  How does Chef configuration management enforce a required device configuration?

  A. The Chef Infra Server uses its configured cookbook to push the required configuration to the remote device requesting updates.

  B. The installed agent on the device connects to the Chef Infra Server and pulls its required configuration from the cookbook.

  C. The Chef Infra Server uses its configured cookbook to alert each remote device when it is time for the device to pull a new configuration.

  D. The installed agent on the device queries the Chef Infra Server and the server responds by pushing the configuration from the cookbook.

  Correct Answer: B

  Chef configuration management enforces a required device configuration by using an installed agent on the device that connects to the Chef Infra Server and pulls the required configuration from the cookbook.

  In Chef, a cookbook is a collection of recipes, attributes, templates, and other configuration files that define a desired configuration for a specific device or group of devices. The Chef Infra Server stores the cookbook, and the installed agent on each device periodically checks in with the server to see if there are any updates to the cookbook.

  If an update is available, the agent pulls the updated cookbook from the server and applies the new configuration to the device. This process is known as "pull-based" configuration management, where the devices actively request updates from the server.
