Which methods are described for connecting VPCs?

• A. Configure customized firewall rules only
• B. Connect a VPC to a corporate intranet only
• C. Configure firewall rules, connect to intranet via VPN, and connect to another AWS VPC using VPC Peering
• D. Use only VPC Peering

Answer: (C)

Connecting VPCs often involves more than one method working together. The best description includes configuring firewall rules to control traffic, establishing a VPN connection to the corporate intranet for secure on‑prem connectivity, and using VPC Peering to connect two AWS VPCs directly. This combination covers on‑prem access, inter‑VPC connectivity, and traffic control, which a single method alone cannot provide. Relying only on firewall rules cannot establish network paths between VPCs or the intranet. Using only a VPN to the intranet does not connect separate AWS VPCs, and using only VPC Peering misses on‑prem connectivity and explicit access policies.
