// Describe VPC Block Public Access (BPA) exclusions. A VPC BPA exclusion is a
// mode that can be applied to a single VPC or subnet that exempts it from the
// account’s BPA mode and will allow bidirectional or egress-only access. You can
// create BPA exclusions for VPCs and subnets even when BPA is not enabled on the
// account to ensure that there is no traffic disruption to the exclusions when VPC
// BPA is turned on. To learn more about VPC BPA, see [Block public access to VPCs and subnets]in the Amazon VPC User Guide.
