CAS-004 Security Architecture Practice Question
An organization is implementing a hybrid cloud architecture and must ensure secure connectivity between its on-premises network and a public cloud VPC. The traffic includes sensitive data that must not traverse the internet. The solution must provide high bandwidth and low latency. Which connectivity option should the architect choose?
Answer choices

AWS Direct Connect
Direct Connect provides a dedicated, private, high-bandwidth connection between on-premises and cloud, bypassing the internet.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS Direct Connect
Why this is correct
Direct Connect provides a private, dedicated connection with high bandwidth and low latency.
- ✗
Site-to-Site VPN over the internet
Why it's wrong here
VPN still traverses the internet, which may not be suitable for sensitive data and low latency.
- ✗
AWS Client VPN
Why it's wrong here
AWS Client VPN establishes encrypted tunnels over the public internet, which directly violates the requirement that sensitive data must not traverse the internet. It is tempting because it provides remote user access to a VPC via a standard VPN client, and would be correct for a scenario where individual teleworkers need secure, client-initiated connections to cloud resources without dedicated private circuits.
- ✗
Internet gateway with encryption
Why it's wrong here
Uses the internet, which may not meet security or latency requirements.
