ANS-C01 Network Implementation Practice Question
Which TWO of the following are valid methods to connect an on-premises data center to an Amazon VPC over a private, dedicated network connection? (Choose two.)
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
✓
AWS Direct Connect
AWS Direct Connect provides a dedicated private connection. AWS VPN can also be used over the internet but is not dedicated; however, a VPN over Direct Connect is possible. The question asks for 'private, dedicated network connection', so Direct Connect is the primary method. VPN over internet is not dedicated. VPN over Direct Connect uses the dedicated connection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VPC peering
Why it's wrong here
VPC peering connects VPCs within AWS, not on-premises.
- ✓
AWS Direct Connect
Why this is correct
AWS Direct Connect provides a dedicated private connection from on-premises to VPC.
- ✓
AWS Direct Connect with a VPN (IPsec) over the private VIF
Why this is correct
A VPN over Direct Connect uses the dedicated connection, providing an encrypted private tunnel.
- ✗
AWS Site-to-Site VPN over the internet
Why it's wrong here
Site-to-Site VPN over the internet uses the public internet, not a dedicated connection.
- ✗
AWS Client VPN
Why it's wrong here
Client VPN is for individual remote clients, not for data center connections.

Same concept, more angles
3 more ways this is tested on ANS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO of the following are valid methods to connect an on-premises data center to a VPC in AWS? (Choose 2.)
easy- ✓ A.AWS Direct Connect
- B.VPC endpoint
- C.Transit Gateway
- ✓ D.AWS Site-to-Site VPN
- E.VPC peering
Why A: AWS Direct Connect is a correct answer because it provides a dedicated, private network connection from an on-premises data center to AWS, bypassing the public internet for consistent latency and higher bandwidth. This service uses industry-standard 802.1Q VLANs to create virtual interfaces, enabling direct access to VPCs via private virtual interfaces (VIFs) or transit virtual interfaces for use with Transit Gateway.
Variation 2. Which TWO of the following are valid methods to connect a VPC to an on-premises network? (Choose TWO.)
easy- ✓ A.AWS Site-to-Site VPN
- ✓ B.AWS Direct Connect
- C.VPC endpoints
- D.AWS Transit Gateway
- E.VPC peering
Why A: AWS Site-to-Site VPN creates an encrypted tunnel over the public internet between a VPC and an on-premises network using IPsec. It is a fully managed, quick-to-deploy method that supports both static routes and BGP dynamic routing via the virtual private gateway.
Variation 3. Which TWO options are valid methods to connect a VPC to an on-premises network? (Choose 2)
medium- A.Internet gateway
- ✓ B.AWS Direct Connect
- C.VPC endpoint
- D.VPC peering connection
- ✓ E.AWS Site-to-Site VPN
Why B: AWS Site-to-Site VPN and AWS Direct Connect are the two primary services for hybrid connectivity. VPC peering is for VPC-to-VPC, not on-premises. VPC endpoints are for accessing AWS services privately. Internet gateway is for public internet access.
