ANS-C01 Question #70: Real Exam Question with Answer & Explanation
The correct answer is D: Create a total of four private VIFs, and enable VPC peering between all VPCs.. -creating VPC peering is free of charge -traffic costs ~0.01/GB for VPC peering (IN + OUT) and ~0.02/GB for direct connect (OUT only). As the communication involved in monitoring will never have IN == OUT, then 0.01 (IN + OUT) will always be lower the 0.02 OUT, ergo VPC peering
Question
A customer has set up multiple VPCs for Dev, Test, Prod, and Management. You need to set up AWS Direct Connect to enable data flow from on-premises to each VPC. The customer has monitoring software running in the Management VPC that collects metrics from the instances in all the other VPCs. Due to budget requirements, data transfer charges should be kept at minimum. Which design should be recommended?
Options
- ACreate a total of four private VIFs, one for each VPC owned by the customer, and route traffic
- BCreate a private VIF to the Management VPC, and peer this VPC to all other VPCs.
- CCreate a private VIF to the Management VPC, and peer this VPC to all other VPCs, enable
- DCreate a total of four private VIFs, and enable VPC peering between all VPCs.
Explanation
-creating VPC peering is free of charge -traffic costs ~0.01/GB for VPC peering (IN + OUT) and ~0.02/GB for direct connect (OUT only). As the communication involved in monitoring will never have IN == OUT, then 0.01 * (IN + OUT) will always be lower the 0.02 * OUT, ergo VPC peering
