- A
AWS Direct Connect
Why wrong: AWS Direct Connect establishes dedicated connections from on-premises to AWS, not between Regions.
- B
VPC Peering
VPC Peering supports cross-Region connectivity, providing a managed, private network path for data replication between VPCs in different Regions.
- C
AWS Site-to-Site VPN
Why wrong: AWS Site-to-Site VPN connects on-premises networks to AWS, not VPCs across Regions.
- D
AWS Global Accelerator
Why wrong: AWS Global Accelerator improves traffic routing over the AWS global network but does not provide private connectivity for data replication; it is used for application acceleration and failover.

ANS-C01 VPC Peering Practice Question
This ANS-C01 practice question tests your understanding of network design. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: vPC Peering. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to improve disaster recovery by replicating data between two AWS Regions. Which AWS service provides a managed solution for cross-Region network connectivity?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPC Peering
VPC Peering supports cross-Region connections, enabling direct network connectivity between VPCs in different AWS Regions. This allows data replication without traversing the public internet, providing low-latency, private connectivity. AWS Global Accelerator is for traffic optimization and failover, not for direct connectivity for data replication.

Why it's wrong here
AWS Site-to-Site VPN connects on-premises networks to AWS, not VPCs across Regions.

AWS Global Accelerator
Why it's wrong here
AWS Global Accelerator improves traffic routing over the AWS global network but does not provide private connectivity for data replication; it is used for application acceleration and failover.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests that VPC Peering supports cross-Region connectivity, which is a managed solution for inter-Region data replication. Candidates may incorrectly choose Global Accelerator, which is for improving application performance and availability, not for establishing direct network paths for data replication.
Detailed technical explanation
How to think about this question
AWS Global Accelerator leverages the AWS global infrastructure, using Anycast IP addresses to direct traffic to the nearest edge location, then routing it over the private AWS backbone to the optimal Regional endpoint. This reduces latency and jitter compared to internet-based routing, and it supports health checks and automatic failover across Regions, making it ideal for disaster recovery where rapid traffic shifting is critical. Under the hood, Global Accelerator uses the same Border Gateway Protocol (BGP) Anycast technique as AWS Shield and Route 53, but with dedicated accelerators and static IP addresses.

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
