CV0-004 Cloud Architecture and Design Practice Question
A company wants to connect its on-premises data center to a public cloud provider with a dedicated, high-bandwidth, low-latency connection. The connection must be private and not traverse the internet. Which connectivity option should be used?
⚠ Common exam trap
CV0-004 often tests whether candidates distinguish dedicated private interconnect (Direct Connect/ExpressRoute) from internet-based VPNs, trapping them into selecting Site-to-Site VPN because it is also 'private' via encryption — but it still traverses the public internet.
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
✓
Direct Connect or ExpressRoute
AWS Direct Connect and Azure ExpressRoute are dedicated private connectivity services that establish a physical cross-connect between the on-premises data center and the cloud provider's network via a colocation facility, bypassing the public internet entirely. They deliver high bandwidth (up to 100 Gbps with LAG) and consistent low latency, satisfying the private, non-internet requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Site-to-Site VPN
Why it's wrong here
A Site-to-Site VPN tunnels over the public internet, so it fails the requirement that traffic not traverse the internet and offers no dedicated bandwidth guarantee. It is tempting because it privately encrypts on-premises-to-cloud traffic, and would be correct for a cheaper, quicker encrypted connection where internet transit is acceptable.
- ✗
Internet gateway
Why it's wrong here
An internet gateway provides public internet connectivity to a VPC, so traffic would traverse the internet, breaching the private-connection requirement. It is tempting because it is a standard VPC attachment, and would be correct when resources genuinely need inbound or outbound public internet access.
- ✗
VPC peering
Why it's wrong here
VPC peering links two virtual private clouds, not an on-premises data centre to a cloud provider, and it cannot provide a dedicated private circuit. It is tempting because it is private and avoids the internet, and would be correct for routing traffic between two VPCs.
- ✓
Direct Connect or ExpressRoute
Why this is correct
Direct Connect and ExpressRoute provide dedicated private circuits between on-premises infrastructure and cloud providers, bypassing the public internet entirely. This satisfies the stem's requirements for high bandwidth, low latency, and privacy. Unlike site-to-site VPNs, which tunnel over the internet, these services deliver consistent performance through a direct physical link.
