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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 is using AWS Transit Gateway to connect multiple VPCs and on-premises data centers. They want to centralize internet traffic through a single VPC that has an internet gateway. Which Transit Gateway feature should they enable?
Transit Gateway route tables
Route tables allow you to centralize internet traffic through a specific VPC.
VPN attachments
Why wrong: VPN attachments are for on-premises connectivity.
Multicast support
Why wrong: Multicast is not for internet traffic centralization.
IPsec acceleration
Why wrong: IPsec acceleration is for VPN performance.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Transit Gateway route tables
To centralize internet traffic through a single VPC with an internet gateway, you need to control the routing of traffic from other VPCs and on-premises networks. Transit Gateway route tables allow you to isolate or share routes between attachments, enabling you to create a default route (0.0.0.0/0) pointing to the centralized VPC's attachment. This ensures all outbound internet traffic from other VPCs is forwarded to the egress VPC, which then uses its internet gateway.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates often confuse Transit Gateway route tables with VPC route tables, thinking that simply attaching an internet gateway to a VPC will automatically route traffic from other VPCs through it, without realizing that explicit route table entries in the Transit Gateway are required to direct traffic to the egress VPC.
Detailed technical explanation
Transit Gateway route tables support route propagation and static routes, allowing you to create a default route (0.0.0.0/0) in the route table associated with spoke VPC attachments, pointing to the attachment of the egress VPC. This design avoids the need for a separate NAT instance or firewall in each VPC, reducing complexity and cost. In a real-world scenario, you might also combine this with a Network Firewall or NAT Gateway in the egress VPC to inspect or translate traffic.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
