Question
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 administrator implement?
Options
- APeering
- BA firewall
- CNetwork access control
- DA load balancer
Explanation
VPC peering establishes direct, private network connectivity between VPCs, solving intra-region and inter-region communication without requiring public internet routing.
Common mistakes.
- B. A firewall controls and filters traffic based on security rules but does not establish the underlying network connectivity path between VPCs.
- C. Network access control lists (NACLs) provide stateless traffic filtering at the subnet level for security purposes, not for creating connectivity between separate VPCs.
- D. 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.
