Episode 40 — WireGuard in Hybrid: why it’s referenced and when it fits
WireGuard appears in CloudNetX objectives as an example of a modern VPN approach, and this episode explains why it is referenced and what it implies in hybrid designs....
Episode 41 — Bastion Hosts: safe admin access paths in hybrid designs
Administrative access is a high-value pathway in hybrid environments, and CloudNetX scenarios often test whether you can design that pathway with minimal exposure and ...
Episode 42 — SSH vs RDP: secure management assumptions the exam tests
Remote management protocols appear in CloudNetX scenarios as design signals about administrative needs, exposure risk, and operational controls, and this episode clari...
Episode 43 — Application Gateways: what they do beyond routing and firewalling
Application gateways show up in CloudNetX scenarios when traffic decisions must be made with application context rather than only IP and port, and this episode explain...
Episode 44 — Service Endpoints: private access patterns for managed services
Service endpoints appear in CloudNetX scenarios as private connectivity options for managed services, and this episode explains how they reduce exposure while simplify...
Episode 45 — Transit Gateways: hub routing without spaghetti networks
Transit gateways appear in CloudNetX scenarios as a way to scale connectivity in cloud and hybrid designs without creating an unmanageable web of peerings and custom r...
Episode 46 — VPC Peering vs Private Link: choosing the right private connectivity model
CloudNetX scenarios often include private connectivity choices that look similar on the surface but carry very different risk and governance implications, and this epi...
Episode 47 — Availability Requirements: turning uptime promises into architecture
Availability requirements appear throughout CloudNetX scenarios as the driver that determines whether a design can tolerate component failure, site loss, or maintenanc...
Episode 48 — Load Balancing Basics: global vs local and what VIP means
Load balancing is a foundational availability and performance mechanism in CloudNetX scenarios, and this episode establishes the baseline concepts needed to reason abo...
Episode 49 — Load Balancing Methods: round robin, least connections, weighted, load-based
CloudNetX scenarios frequently ask you to choose a load balancing method that matches application behavior and infrastructure variability, and this episode clarifies t...
Episode 50 — High Availability Patterns: active-active vs active-passive tradeoffs
High availability patterns are a recurring CloudNetX decision point because they determine whether a service continues through failures, how complex synchronization mu...
Episode 51 — Link Aggregation: capacity, redundancy, and failure behavior
Link aggregation shows up in CloudNetX scenarios because it is one of the simplest ways to increase uplink capacity while also improving resilience, but it behaves dif...
Episode 52 — Autoscaling: availability, cost control, and risk of runaway scaling
Autoscaling appears in CloudNetX scenarios as an availability and cost control mechanism, but the exam expects you to recognize that autoscaling is only as good as the...
Episode 53 — Regions and Availability Zones: designing around failure domains
Regions and availability zones are tested in CloudNetX as building blocks for resilience, and this episode explains how to treat them as deliberate failure domains rat...
Episode 54 — CDN Decisions: performance, resilience, and correct placement
CDNs appear in CloudNetX scenarios as performance and resilience tools, and this episode explains how to decide when a CDN is appropriate and where it belongs in the d...
Episode 55 — Fault Domains and Update Domains: planning for “planned failure” events
CloudNetX scenarios often assume you can design for failure that is scheduled, not just failure that is accidental, and this episode explains fault domains and update ...
Episode 56 — Redundancy Strategy: devices, paths, and eliminating single points of failure
Redundancy is a constant theme in CloudNetX because “high availability” is rarely achieved with one feature; it is achieved by eliminating single points of failure acr...
Episode 57 — Power Planning: voltage, wattage, amperage, PDUs, UPS essentials
Physical campus requirements in CloudNetX include power planning because networks fail in predictable ways when electrical capacity and protection are treated as after...
Episode 58 — Power Events: blackout, brownout, surge, spike and protective choices
CloudNetX expects learners to understand how different power events affect infrastructure and what protections are appropriate, because these events create outages tha...
Episode 59 — Environmental Requirements: temperature, humidity, BTUs, and failure prevention
Environmental requirements are included in CloudNetX because many infrastructure failures are driven by heat, airflow, and humidity conditions that degrade performance...
