CV0-003 Question #428: Real Exam Question with Answer & Explanation
The correct answer is A: Dual direct peering/connections from headquarters to one cloud region.. Dual dedicated direct connections to a cloud region provide the most reliable, redundant connectivity for headquarters users without introducing a single ISP as a point of failure.
Cloud Architecture and Design
Question
To enhance availability, a company has expanded its public cloud presence to multiple regions from a single CSP. The company wants to ensure resources in the public cloud are highly available to users at company headquarters. Which of the following is the BEST solution to fulfill this requirement?
Options
- ADual direct peering/connections from headquarters to one cloud region.
- BDual VPN connections over a single ISP from headquarters to one cloud region.
- CDual VPN connections over two separate ISPs from headquarters to both cloud regions.
- DDual direct peering/connections over a single ISP from headquarters to both cloud regions
Explanation
Dual dedicated direct connections to a cloud region provide the most reliable, redundant connectivity for headquarters users without introducing a single ISP as a point of failure.
Common mistakes.
- B. Routing both VPN connections through a single ISP introduces that ISP as a single point of failure, and VPN tunnels over the public internet are inherently less reliable and performant than dedicated direct connections.
- C. Although dual VPN connections over two separate ISPs to both regions add ISP diversity, VPN tunnels are less reliable and performant than dedicated circuits, making this option inferior to direct peering for a high-availability requirement.
- D. Dual direct connections over a single ISP still leaves that ISP as a single point of failure - an ISP outage would sever both connections simultaneously despite the connections reaching both cloud regions.
Concept tested. Dedicated cloud direct connectivity redundancy for headquarters access
