Episode 20 — Dynamic Routing Overview: what changes when routes must adapt
Dynamic routing protocols change how networks behave under failure and growth, and CloudNetX scenarios often test whether you understand those behavioral shifts rather...
Episode 21 — OSPF vs BGP: which problem each one is solving
OSPF and BGP appear in CloudNetX scenarios as signals about routing scope and intent, and this episode clarifies the distinct problems each protocol solves. It defines...
Episode 22 — BGP Design Thinking: peering intent, policy, and stability
BGP design in CloudNetX scenarios is rarely about memorizing attributes and more about understanding peering intent, route control, and operational stability. This epi...
Episode 23 — Container Networking Basics: why workloads change network assumptions
Containerized workloads change network assumptions because services become more dynamic, more distributed, and often more dependent on naming and policy than on fixed ...
Episode 24 — Network Virtual Interfaces: what vNICs imply for control and visibility
Virtual network interfaces are the attachment points where workloads connect to networks and where many policy decisions are enforced, making them central to CloudNetX...
Episode 25 — Picking a Topology: star, mesh, hub-and-spoke, point-to-point
Topology selection in CloudNetX scenarios is about matching connectivity structure to traffic patterns, resilience needs, and operational capacity, and this episode ex...
Episode 26 — Spine-and-Leaf: what it optimizes and when it’s justified
Spine-and-leaf designs appear in CloudNetX content as a scalable approach for environments with heavy east/west traffic, and this episode explains what the architectur...
Episode 27 — Network Zones: trusted, untrusted, and screened subnet decisions
Network zoning is a recurring theme in CloudNetX scenarios because it provides a simple, defensible way to structure trust and control access. This episode defines tru...
Episode 28 — Traffic Flows: designing for north/south versus east/west
Traffic flow direction is one of the fastest ways to interpret a scenario and choose appropriate controls, and this episode builds a practical model for north/south an...
Episode 29 — Segmentation Fundamentals: why segmentation fails and how to make it stick
Segmentation is a foundational security and resilience strategy in CloudNetX scenarios, but it frequently fails in real environments due to unclear requirements and un...
Episode 30 — VLAN Segmentation: what it solves and common design traps
VLANs remain a common segmentation mechanism in campus and data center scenarios, and this episode explains what VLAN segmentation solves and where it commonly goes wr...
Episode 31 — VXLAN: what overlays enable and why architects use them
VXLAN appears in modern network design scenarios as a way to extend segmentation across large environments without relying on traditional Layer 2 scaling limits. This ...
Episode 32 — GENEVE: where encapsulation shows up and what it implies
Encapsulation shows up in CloudNetX scenarios because modern segmentation and service chaining often rely on tunnels that carry one network inside another, and this ep...
Episode 33 — Production vs Non-Production: separation, blast radius, and governance
Separation between production and non-production is a recurring architectural requirement because it reduces risk, supports governance, and prevents testing from becom...
Episode 34 — WAN Selection Framework: MPLS, SD-WAN, DIA, metro, dark fiber
WAN choices in CloudNetX scenarios require aligning connectivity options to business outcomes, operational constraints, and performance requirements rather than select...
Episode 35 — Cellular Links: when constraints make cellular the best answer
Cellular connectivity appears in CloudNetX scenarios as a pragmatic option when traditional wired connectivity is unavailable, delayed, or insufficiently resilient, an...
Episode 36 — Satellite Links: latency reality and use cases that fit
Satellite connectivity shows up in CloudNetX scenarios as an option of necessity, chosen when terrestrial connectivity is unavailable or when geographic reach outweigh...
Episode 37 — Cloud Interconnects: Direct Connect, ExpressRoute, SDCI selection logic
Private cloud interconnects appear in CloudNetX scenarios as mechanisms to improve predictability, reduce exposure to the public internet, and support compliance-drive...
Episode 38 — VPN Types: site-to-site vs point-to-site vs remote access
VPN scenarios in CloudNetX require distinguishing connectivity intent, trust scope, and operational impact, and this episode provides clear models for the main VPN typ...
Episode 39 — Split Tunneling: security and performance tradeoffs in plain language
Split tunneling is frequently tested as a tradeoff decision because it changes where traffic flows and which security controls see it, and this episode explains that d...
