| Network verification checks run automatically when you deploy an {product-title} cluster into an existing Virtual Private Cloud (VPC) or create an additional machine pool with a subnet that is new to your cluster. The checks validate your network configuration and highlight errors, enabling you to resolve configuration issues prior to deployment. | ||

| In the isolated backplane flow, SREs request access to a customer's support role. This request is just-in-time (JIT) processed by the backplane API which dynamically updates the organization role's permissions to a specific SRE personnel's account. This SRE's account is given access to a specific Red{nbsp}Hat customer's environment. SRE access to a Red{nbsp}Hat customer's environment is a temporary, short-lived access that is only established at the time of the access request. | ||

| Access to the STS token is audit-logged and traceable back to individual users. Both STS and non-STS clusters use the AWS STS service for SRE access. Access control uses the unified backplane flow when the `ManagedOpenShift-Technical-Support-Role` has the `ManagedOpenShift-Support-Access` policy attached, and this role is used for administration. Access control uses the isolated backplane flow when the `ManagedOpenShift-Support-Role` has the `ManagedOpenShift-Technical-Support-<org_id>` policy attached.
