A nutanix user VPC called servers has three subnets called Tier1, tier2 and Darren-Tier3.
* Servers:10.0.0.0/16
* Tier1: 10.0.0.0/16
* Tier2: 10.0.0.0.128/25
* Darren-Tier3:10.0.4.0/24
An administrator wants to keep Darren-Tier3 isolated and not receive any outside traffic. In order properly route for Tier1 and Tier2 coming from native subnets for Azure, what should the ERP be set to?
- Transit VPC ERP set to 10.0.0.0/20 and Servers ERP set to 10.0.0.0/24
- Transit VPC ERP set to 10.0.0.0/16 and Servers ERP set to 10.0.0.0/25
- Transit VPC ERP set to 10.0.0.0/24 and Servers ERP set to 10.0.0.0/24
- Transit VPC ERP set to 10.0.0.0/16 and Servers ERP set to 10.0.4.0/24
Answer(s): D
Explanation:
ERP Configuration: ERP (External Route Prefix) settings determine how traffic is routed between subnets and VPCs.
Objective: The goal is to isolate Darren-Tier3 while ensuring proper routing for Tier1 and Tier2. Transit VPC ERP: Setting it to 10.0.0.0/16 ensures that it covers the entire VPC range, allowing traffic within Tier1 and Tier2.
Servers ERP: Setting it to 10.0.4.0/24 ensures isolation for Darren-Tier3 by limiting traffic to that specific subnet and preventing external traffic from reaching it. Conclusion: This configuration achieves the isolation of Darren-Tier3 while allowing proper routing for Tier1 and Tier2.
