A company has a large environment with multiple VPCs across three regions in a public cloud. The company is concerned about connectivity within the regions. Which of the following should the cloud adm

VPC peering creates a private network connection between two or more VPCs, allowing resources in each VPC to communicate using private IP addresses as if they were on the same network. In a multi-VPC, multi-region environment, peering connections can be established both within and across regions to address connectivity concerns. This is the purpose-built solution for enabling VPC-to-VPC communication in a public cloud.

A firewall controls and filters traffic based on security rules but does not establish the underlying network connectivity path between VPCs.

Network access control lists (NACLs) provide stateless traffic filtering at the subnet level for security purposes, not for creating connectivity between separate VPCs.

A load balancer distributes incoming traffic across multiple backend targets to improve availability and performance, but it does not create routable network paths between VPCs.
