QuestionQ2

Unknown / not found in official Broadcom sources

A cloud service provider operates VPCs with varying traffic patterns:

  • Some VPCs produce high-volume North/South flows.
  • Most VPCs generate very little traffic.

The architect must optimize Edge dataplane resource consumption while ensuring noisy VPCs do not affect others.

Which optimization meets the requirement?

  • A Use multiple Edge clusters and distribute VRF-backed VPCs based on traffic profiles.
  • B Convert high-traffic VPCs into VLAN-backed segments attached directly to Tier-0 gateways.
  • C Reduce the number of VPCs by consolidating VPCs into shared namespaces.
  • D Assign one dedicated Edge node per high-traffic VPC.
Explanation

Separate Edge clusters can be assigned to VRF-backed VPCs based on their traffic profiles. This contains high-volume north/south traffic within appropriately sized Edge resources, preventing those VPCs from consuming the shared dataplane capacity needed by low-traffic VPCs while preserving tenant routing isolation.
