🔁 Tasks 3 & 4 — Peering & Connectivity Test

Peering created bidirectionally between CoreServicesVnet and ManufacturingVnet, followed by a successful test using Network Watcher.

ℹ️ Note: Initial unreachable connectivity test was skipped due to Terraform provisioning order. The peering between CoreServicesVnet and ManufacturingVnet had already been applied, so Network Watcher confirmed reachability on first capture.

🧪 Task 5 — Verify VM-to-VM Reachability

Connectivity validated using Test-NetConnection via Azure Run Command from ManufacturingVM.
