C90.05 (also written C90-05) is Arcitura's Advanced Cloud Architecture exam, Module 5 of the Certified Cloud Architect track. It tests advanced cloud design patterns for elastic, resilient, multitenant, and containerized architectures, including load balancing, storage tiering, failover, serverless deployment, cloud bursting, and cloud balancing. The exam is vendor-neutral.
C90.05 Advanced Cloud Architecture is the module where Arcitura's Cloud Architect track moves from foundational patterns to the complex designs real cloud platforms depend on. It builds directly on Module 4 (Fundamental Cloud Architecture). It covers how to make cloud environments elastic, fault-tolerant, and multitenant, and how to extend workloads across private and public clouds.
TroyTec's C90.05 prep includes 50 practice questions in PDF and Online Test Engine formats, focused on the patterns and mechanisms this module tests.
Exam code: C90.05 (C90-05)
Exam name: Advanced Cloud Architecture
Vendor: Arcitura Education
Certification track: Certified Cloud Architect (Module 5 of 5)
Builds on: Module 4, Fundamental Cloud Architecture (C90.04)
Leads to: Module 6, Cloud Architecture Lab (C90.06)
Core focus: Elastic, resilient, multitenant, and containerized cloud architectures
The C90.05 exam validates your knowledge of advanced cloud computing design patterns. These are reusable architectural solutions for scaling resources automatically, surviving failures without downtime, isolating tenants and containers, and optimizing storage and network performance. It goes deeper than foundational architecture by focusing on how patterns combine into complete, production-grade technology architectures.

Key Patterns and Concepts : Cloud bursting (burst in and burst out between private and public clouds), cloud balancing
Elastic architecture lets a cloud environment grow or shrink its compute, network, and storage capacity automatically based on demand. For C90.05, know how elastic resource capacity, elastic network capacity, and elastic disk provisioning work, and where serverless deployment fits.
Resilient architecture keeps cloud services running when components fail. The exam covers hypervisor clustering, redundant storage, automated failure detection and recovery, and zero-downtime designs that move workloads without interrupting service.
Advanced storage patterns manage performance and availability across storage devices. Examples include LUN migration, vertical tiering (moving data between faster and slower storage), live storage migration, and scheduled storage maintenance windows.
These patterns isolate workloads that share the same infrastructure. You'll need to understand multi-container isolation control, volatile container configuration, and coordination patterns such as leader node election and micro scatter-gather.
Cloud bursting sends extra workload from a private cloud to a public cloud when demand peaks ("burst out"), then brings it back ("burst in"). Cloud balancing spreads workloads across multiple clouds to improve performance and resilience.

Candidates who have completed C90.04 and are working toward Arcitura's Cloud Architect certification
C90.05 is Arcitura's Advanced Cloud Architecture exam, Module 5 of the Certified Cloud Architect track. It tests advanced cloud design patterns for elastic, resilient, multitenant, and containerized architectures, plus cloud bursting and cloud balancing.
Yes. Arcitura's official code is C90.05. It's often written as C90-05, but both refer to the same Advanced Cloud Architecture exam.
C90.05 is part of the Arcitura Certified Cloud Architect certification in the Cloud Computing School program.
It covers elastic capacity, resilient architecture and failover, load balancing, advanced storage architecture, container isolation and coordination, serverless deployment, cloud bursting, and cloud balancing.
No. Arcitura exams are vendor-neutral. The patterns apply to AWS, Microsoft Azure, Google Cloud, and private clouds.
The complete Cloud Architect exam, covering Modules 1, 2, 4, 5, and 6, runs 170 minutes. The partial exam, covering Modules 4, 5, and 6, runs 110 minutes.
Yes. C90.05 builds directly on the foundational patterns in C90.04, so studying Module 4 first makes the advanced patterns much easier to follow.
