AWS Certified SysOps Administrator – Associate (legacy) — Question 664

A company is evaluating solutions for connecting its data centers to a VPC in an AWS Region running a mission-critical application. A secondary Region has already been set up as a disaster recovery solution. The company needs a consistent, low-latency connection of at least 10 Gbps that must be highly resilient and fault tolerant.
Which solution meets these requirements?

Answer options

• A. Set up a 10 Gbps AWS Direct Connect connection at two Direct Connect locations. Use two customer routers and dynamically routed, active/active connections.
• B. Set up a 10 Gbps AWS Direct Connect connection. Use a Direct Connect gateway to support both Regions.
• C. Establish an AWS Direct Connect connection for the primary connection to the VPC with an AWS-managed VPN connection as a backup.
• D. Establish 10 VPN connections to the VPC. Enable the VPN Equal Cost Multipath (ECMP) feature to balance traffic over the active connections.

Correct answer: B

Explanation

Using an AWS Direct Connect gateway allows a single Direct Connect connection to interface with VPCs across multiple AWS Regions, which directly supports the requirement for both the primary and disaster recovery Regions. Direct Connect provides the necessary consistent, low-latency 10 Gbps performance that standard Internet-based VPN connections cannot guarantee. This setup optimizes multi-region architecture while meeting the high-bandwidth demands of the workload.
