CloudNetX PrepCast Trailer: Learn How the Exam Thinks, Not Just What It Asks
The CloudNetX PrepCast is an exam-focused, audio-first course built to teach architectural decision-making in modern hybrid networks. This trailer introduces how the ...
Episode 1 — How CloudNetX Questions Work: scenario clues, constraints, and “best answer” logic
CloudNetX questions often look like technical recall, but they are built to evaluate whether you can extract intent from a scenario and choose an option that fits stat...
Episode 2 — Your Hybrid Network Mental Model: zones, flows, and control points
Hybrid networking scenarios require you to reason about traffic paths without relying on diagrams, so this episode builds a mental model that stays stable across cloud...
Episode 3 — The Four Exam Priorities: security, availability, performance, and cost tradeoffs
Most CloudNetX decisions can be explained through four priorities that compete in predictable ways: security, availability, performance, and cost. This episode defines...
Episode 4 — Reading Requirements Like an Architect: what the question is really asking
Architecture thinking starts with interpreting requirements correctly, and this episode teaches a structured approach to reading prompts like an architect rather than ...
Episode 5 — Fast Recall System: turning objectives into mental checklists
Audio-first preparation depends on retrieval, not recognition, so this episode builds a fast recall system that converts objectives into short, repeatable mental check...
Episode 6 — Final Prep Strategy: how to review and self-test using audio only
Audio-only preparation works when review is planned as a loop rather than a linear pass, and this episode defines a structured approach that keeps concepts accessible ...
Episode 7 — OSI as a Design Tool: translating requirements into network decisions
The OSI model is often treated as a memorization task, but CloudNetX scenarios use it as a reasoning framework for design choices and fault isolation. This episode ref...
Episode 8 — IPv4 Addressing Strategy: public/private, static/dynamic, and design implications
IPv4 addressing is a foundational design element in CloudNetX scenarios because it affects segmentation, routing, identity mapping, and operational clarity. This episo...
Episode 9 — Subnetting for Architects: CIDR, VLSM, and right-sizing networks
Subnetting is frequently tested in CloudNetX scenarios as a design reasoning skill, not as an arithmetic exercise, and this episode teaches how to use CIDR and VLSM to...
Episode 10 — IPv6 Strategy in Hybrid: adoption patterns, common pitfalls, and exam cues
IPv6 appears in CloudNetX scenarios as a coexistence and transition problem rather than as a complete replacement, and this episode builds a practical strategy for hyb...
Episode 11 — TCP vs UDP Decisions: reliability, latency, and application fit
Transport protocol choices appear in CloudNetX scenarios as design decisions that shape reliability, performance, and troubleshooting outcomes, so this episode clarifi...
Episode 12 — NAT Patterns: port forwarding vs PAT and what each solves
NAT shows up in CloudNetX scenarios because it sits at the intersection of addressing, reachability, logging, and security policy, and this episode explains the most c...
Episode 13 — NAT64 and IPv6 Interop: when it appears and what breaks
NAT64 appears in CloudNetX scenarios as an interoperability tool used when IPv6-enabled clients must reach IPv4-only destinations, and this episode explains how it wor...
Episode 14 — DHCP by Design: scope sizing, resilience, and failure signals
DHCP is a core dependency in many network scenarios, and CloudNetX often tests whether you understand how DHCP design choices affect availability and troubleshooting o...
Episode 15 — NTP by Design: time dependencies, auth impact, and incident clues
Time is a hidden dependency in almost every modern network and security system, and this episode explains why NTP design matters for both operations and incident respo...
Episode 16 — DNS Resolution Flow: dependencies, recursion, and where failures hide
DNS is a critical dependency in nearly every CloudNetX scenario, yet its failures often appear as unrelated application or connectivity problems. This episode breaks d...
Episode 17 — Secure DNS: DNSSEC vs DoT vs DoH and what each protects
Secure DNS options appear in CloudNetX scenarios as targeted protections rather than blanket solutions, and this episode clarifies what each mechanism actually provide...
Episode 18 — Authentication Protocols: 802.1X, RADIUS, TACACS+, LDAP in scenarios
Authentication protocols are frequently referenced in CloudNetX scenarios as indicators of where and how access decisions are made, and this episode establishes clear ...
Episode 19 — Static Routing: simplicity benefits and operational risks
Static routing appears in CloudNetX scenarios as both a valid design choice and a hidden risk, depending on context, and this episode explains how to evaluate it corre...
