Exam 3V0-12.26 Topic 1 Question 42 Discussion

B addresses the network-isolation requirement by keeping security-policy enforcement within the individual VPC boundary . VMware VPCs are designed as isolated networking and security domains in which tenant administrators can maintain VPC-specific firewall and networking policies. NSX VPC security provides distributed firewalling and microsegmentation close to workload interfaces, allowing east-west traffic to be restricted without depending on a shared tenant security object. Broadcom describes VPC administrators ' network and security policies as contained within their VPC and not affecting other VPCs. ( VMware Blogs ) C addresses identity isolation. VCF Automation organizations provide independent administrative and access- control boundaries, and each organization can configure its Identity Provider connection and organization- specific users/groups . This enables API consumers to authenticate within the appropriate organizational identity scope instead of sharing credentials or tenant identities.
A introduces shared provider-managed security constructs, conflicting with the no-shared-security-objects requirement. D concerns IP-address efficiency rather than zero-trust enforcement. E introduces shared routing infrastructure and depends on route filtering rather than enforcing isolation directly at each VPC boundary.
