In VMware Cloud Foundation 5.2, NSX Edge clusters provide critical networking services, such as North-South connectivity via Tier-0 Gateways, often using BGP for dynamic routing. Deploying NSX Edges via SDDC Manager integrates them into the VCF lifecycle management framework, which impacts their configuration and operational capabilities. Let’s analyze each option:
Option A: NSX Edges deployed via SDDC Manager can be updated separately in the futureIn VCF, SDDC Manager manages the lifecycle (deployment, upgrades, etc.) of NSX components, including Edge nodes. However, updates are not performed “separately” from the VCF stack; they are part of a coordinated upgrade process across the management domain. TheVCF 5.2 Administration Guidenotes that Edge updates are tied to NSX Manager and SDDC Manager workflows, contradicting the idea of independent updates. This doesn’t justify the design decision.
Option B: VPN service in NSX will be available and configurable via SDDC Manager with NSX Edges deployed using this methodWhen NSX Edges are deployed via SDDC Manager in the Management Domain, they are fully integrated into the VCF architecture. This enables advanced NSX features, such as VPN services (L2VPN, IPsec VPN), to be configured and managed through SDDC Manager or NSX Manager UIs. TheVMware Cloud Foundation 5.2 Networking Guideconfirms that deploying Edges via SDDC Manager supports North-South connectivity (e.g., via Tier-0 with BGP) and additional services like VPN, providing operational flexibility. This justifies the decision by aligning with VCF’s integrated management capabilities.
Option C: Extra Large form factor is available only when edges are deployed using SDDC ManagerNSX Edge form factors (Small, Medium, Large, Extra Large) are determined by resource requirements and deployment method, but the Extra Large form factor is available whether Edges are deployed manually via NSX Manager or through SDDC Manager in VCF. TheNSX-T Data Center Installation Guide(part of VMware docs) clarifies that form factor selection is independent of the deployment tool, making this statement inaccurate and not a justification.
Option D: This deployment method will automatically configure dynamic routingDeploying Edges via SDDC Manager automates some aspects of setup (e.g., cluster creation, basicnetworking), but dynamic routing (e.g., BGP) requires manual configuration of peers, ASNs, and route maps via NSX Manager. TheVCF 5.2 Networking Guidestates that while SDDC Manager streamlines deployment, BGP configuration remains a post-deployment task, disproving “automatic” configuration as a justification.
Conclusion:Option B is the correct justification because deploying NSX Edges via SDDC Manager ensures integration with VCF’s management plane, enabling features like VPN services alongside BGP-based North-South connectivity in the Management Domain. This aligns with the architect’s goal of leveraging VCF’s centralized management strengths.References:
