What should you do before pairing a large number of VENs?

Before pairing a large number of Virtual Enforcement Nodes (VENs), performing a backup of the Policy Compute Engine (PCE) is crucial. The PCE is central to the Illumio Core architecture, managing policy definitions and enforcement for workload security. By backing up the PCE prior to a large pairing operation, you ensure that you have a recoverable state of your policies and configuration. This is vital because if any issues arise during the pairing, such as misconfigurations or system performance degradation, you can restore the PCE to its previous stable state without losing vital policy data or configurations.

In the context of managing security and compliance, having this backup minimizes the risks associated with introducing numerous VENs at once, as it allows for restoration in case of failure. This proactive measure safeguards your environment and helps maintain the operational integrity of your security policies.
