Creating VKS Supervisor Clusters with NSX VPC, Segment, vDS and Avi (VCAP-VKS Exam Series, Part 16)
Three workload networks and three load balancer providers give nine pairings on paper and five legal ones in the product. Here is the activation matrix, the preflight per path, and the failures that stall a Supervisor at 68 percent.

vSphere Namespace Ingress and Egress Design Options (VCAP-VKS Exam Series, Part 13)
Objective 3.3 is an address design question, not a wizard question. How ingress and egress differ across the three Supervisor networking modes, which pool runs out first on a real estate, and what you can still change once the Supervisor is enabled.

VKS Namespace Network Options and Their Implications (VCAP-VKS Exam Series, Part 12)
Objective 3.2 asks you to evaluate the implication for Namespace Network options. Here is what each of the three models commits you to, which fields lock the moment you click Create, and the subnet prefix arithmetic that decides how many VKS nodes a namespace will ever hold.

VKS CNI, NSX Networking Objects and TLS Trust for Secure Clusters (VCAP-VKS Exam Series, Part 10)
Objective 2.5, printed a second time, covers CNIs, NSX networking objects and TLS certificates. Here is the Supervisor level CNI switch, the AntreaConfig override, and the double base64 certificate trap that wedges a VKS cluster in Provisioning.

Supervisor Networking with VDS, NSX Segments or VPCs and Load Balancing (VCAP-VKS Exam Series, Part 6)
Objective 2.2 is not a load balancer comparison. Your workload network picks the shortlist, and on NSX VPC the shortlist has one name on it. Mapping table, discovery commands and the rebuild that taught me to ask the security question first.

Reference Architecture for a VKS Deployment, NSX, VDS and Zones (VCAP-VKS Exam Series, Part 4)
Objective 1.3 asks you to pick a reference architecture, not describe one. Here are the four published vSphere Zone models, the four Supervisor networking paths, and the single decision you can never take back.

Network Policy on VKS, NSX-T DFW to Antrea (TKGI to VKS Series, Part 16)
NSX-T distributed firewall rules do not migrate to VKS. Rebuild them as tiered Antrea policy with a working default deny, verified against a real stateful app.

Supervisor Networking on VCF 9, NSX VPCs and Load Balancer Choices (TKGI to VKS Series, Part 13)
Your vSphere Supervisor load balancer is a one-way door on VCF 9. Here is how Foundation LB, NSX LB and Avi compare across NSX VPC networking when you move a TKGI estate to VKS.
-
Networking Assessment for TKGI to VKS, NSX-T vs NSX VPC (TKGI to VKS Series, Part 7)
Assess your TKGI NSX-T pod networking against the NSX VPC and Antrea model VKS uses on VCF 9, with a construct by construct mapping table and the addressing math that decides the target design.

VCF 9.x Pre-Installation Checklist: What to Verify Before You Start the VCF Installer
A pre-check list for a fresh VMware Cloud Foundation 9.x management domain deployment (9.0 and 9.1), with the command to run for each item plus MTU-per-traffic and password requirement tables.

Cloud Accounts in VCF Automation: Connecting vCenter and NSX (VCF Automation 9 Series, Part 9)
A cloud account is the credential that lets VCF Automation collect inventory and deploy. Adding vCenter and NSX accounts, the VCF account and SDDC Manager, and the NSX manager-mode removal in 9.0.

Troubleshooting NSX 9 DFW and Security Policy: Applied-To, Realized Rules and the Default-Rule Trap (NSX Series, Part 30)
The most common DFW outage is a published rule with the wrong Applied-To. Here is how to see what is really realized on a vNIC, why a rule visible in the UI may not be applied, the default-rule trap, and the symptom-to-fix path. The NSX Series finale.
