# Quarantine Broker Concepts

To use a Quarantine Broker, there are two components: the Quarantine Broker, and a method to Set Quarantine (send Engine Daemons to the Quarantine Broker) and Clear Quarantine (change Engine Daemon status to allow Engine Daemons to log onto production Brokers.)

The Quarantine Broker is specified on the Director. When the Quarantine Broker is specified, the Director allows individual Engine instances to log in to either the production Brokers or the Quarantine Broker based on the value of quarantine status of the managing Engine Daemon. If the quarantine status of an Engine Daemon is “Verified”, all Engines managed by the Engine Daemon might only log in to the production Brokers. Otherwise, the Engines might only log in to the Quarantine Broker.

When using Engine balancing and a Quarantine Broker, the balancing only occurs on the production Brokers. The Quarantine Broker is ignored for the purposes of Engine balancing, and only verified Engines are balanced between the production Brokers.

If the Quarantine Broker is not set in a grid, Engines might log in to any Brokers in the grid allowed by routing and balancing configurations.
