Use this topic map to guide your study for Arcitura Education C90.03 (Cloud Technology Lab) within the Certified Cloud Technology Professional path.
The C90.03 exam combines multiple question types to assess both theoretical understanding and practical judgment. Questions progress in difficulty, requiring you to apply knowledge to realistic cloud scenarios.
Questions emphasize practical reasoning and real-world application, so study with a focus on "why" and "when," not just "what."
An effective study plan breaks the 18 modules into manageable weekly goals, combines focused reading with practice questions, and includes mock exams to build pacing and confidence. Allocate 4-6 weeks if you have foundational cloud experience, or 8-10 weeks if you are newer to the subject.

Cloud Fundamentals & Architecture, Networking & Connectivity, and Security & Compliance typically account for 30-40% of exam questions, as they underpin all other cloud decisions. However, all 18 modules are fair game, so balanced preparation is essential. Focus extra attention on topics that connect across multiple domains, such as Identity & Access Management, which intersects with Security, Networking, and Compliance.
Modules form a workflow: you start with Architecture to define the solution, then use Compute, Storage, and Networking to build infrastructure, add Identity & Access Management for security, deploy via Infrastructure as Code, monitor with Logging & Monitoring, and optimize using Cost & Performance Tuning. Exam questions often test your understanding of these dependencies, so study how one module's decision affects others (e.g., how a security policy impacts network design).
Hands-on experience is valuable but not mandatory; the exam tests reasoning and decision-making, not memorized CLI commands. If you have access to the Cloud Technology Lab environment, spend 20-30% of study time configuring resources, testing scenarios, and troubleshooting errors. This builds confidence and helps you recognize real-world patterns. If lab access is limited, focus on understanding concepts deeply and visualizing workflows.
Frequent errors include overlooking trade-offs (choosing the cheapest option without considering performance or security), misunderstanding when to use specific services (e.g., serverless vs. containers), and skipping the "why" behind best practices. Many candidates also rush through scenario-based questions without fully reading the constraints. Slow down, identify what the question is really asking, and eliminate obviously wrong answers before choosing.
In your final week, take a full-length mock exam under timed conditions to simulate exam pressure and identify any remaining weak areas. Review all incorrect answers and re-read the relevant module sections. Create a one-page summary of key decision trees (e.g., "when to use IaaS vs. PaaS," "how to choose a database engine") and review it daily. Avoid cramming new material; instead, reinforce what you already know and build confidence.
Cloud X (owned by Cloud Provider X) provides Physical Server A which hosts Virtual Servers A and B. Virtual Server B hosts Ready-Made Environments A and B. Cloud Service Consumer A uses Virtual Server A as part of an IaaS leasing agreement in which Cloud Consumer A is charged a fixed monthly fee for unlimited access. Cloud Service Consumers B and C use Ready-Made Environments A and B respectively as part of a PaaS leasing agreement based on per-minute usage fees. In both cases, access is monitored via Pay-For-Use Monitor A, which keeps track of log-in and log-out times in order to calculate the usage charges that are billed to Cloud Consumers B and C . Virtual Server A begins generating a series of exceptions. Soon thereafter, Virtual Server B becomes destabilized, resulting in further exceptions being raised in Ready-Made Environments A and B. Cloud Service Consumers B and C receive a series of error messages until both of their connections are dropped Finally, Physical Server A shuts down completely. A subsequent investigation reveals that Virtual Server A was the victim of a security attack performed by a malicious cloud service consumer, the attacker generated increased loads of external communication requests on Virtual Server A and the underlying network, causing Physical Server A (along with Virtual Server B) to eventually shut down.
Which of the following statements accurately identifies the type of security threat that corresponds to the described attack - and -provides a solution that can directly mitigate this type of security threat within Cloud X?
Cloud Provider Y owns Cloud Y, which provides a set of cloud services, virtual servers, and one physical server. Cloud Services A and B are hosted on Virtual Server A, which is hosted by Physical Server A . Physical Server A also hosts Virtual Server B, which hosts redundant implementations of Cloud Services A and B for load balancing purposes. Cloud Service Consumer A is accessing Cloud Service A located on Virtual Server A . Cloud Service Consumer B is accessing Cloud Service B located on Virtual Server B . Cloud Service Consumers A and B are both owned by Cloud Consumer X. Cloud Consumer X has recently complained that Cloud Service A is becoming increasingly unreliable. Cloud Provider Y launches an investigation that reveals that Virtual Server A has been crashing sporadically due to successful malicious intermediary attacks where malicious service agents have been inserting harmful data into messages sent by Cloud Service Consumer A to Cloud Service A
Which of the following statements describes a solution that can mitigate the malicious intermediary attacks that have been occurring on Virtual Server A - and - can further help prevent the same types of attacks from occurring on Virtual Server B?
Organization A has been expanding and, as a result, is outgrowing the processing capacity of its on-premise Service A implementation. It is determined that this is due to usage thresholds of Service A and complex data processing limitations in Database A . The diagram depicts Organization A's current on-premise environment, where Service Consumers A . B and C attempt to access Service A at the same time. Service Consumer A successfully accesses Service A, which then successfully retrieves the requested data (1). Service Consumer B successfully accesses Service A, but due to the complex data structure, the request for the data times out and fails (2). Finally, Service Consumer C attempts to access Service A, but is rejected because Service A is unable to accept more concurrent requests.
Organization A is required to continue using its on-premise Service A implementation, with the exception of Database A, which does not need to remain on-premise. Database A is dedicated to Service A and is comprised of relational data. Which of the following statements provides a solution that uses cloud-based IT resources to solve the performance limitations of Service A and Database A?
Cloud Provider X (which owns Cloud X) deploys two physical servers (Physical Servers A and B) and two databases (Databases A and B). Virtual Servers A and B are hosted by Physical Server A and Ready-Made Environments A and B are hosted by Virtual Server B . Virtual Servers C and D are hosted by Physical Server B . Cloud Service Consumer A regularly accesses Virtual Server D in order to test and deploy a new cloud service that was developed on-premise by the cloud consumer organization operating Cloud Service Consumer A . Cloud Service Consumer B (operated by a different cloud consumer organization) has been regularly accessing Ready-Made Environment A in order to develop and deploy a different new cloud service.
Cloud X is a private cloud that, to-date, has been set up within the cloud provider company to provision IT resources free of charge to internal cloud consumers, via PaaS and IaaS delivery models. The cloud consumers that have been operating Cloud Service Consumers A and B represent different IT departments within the company that have been working separately on the development of new cloud services. Cloud Service Consumer A has been accessing Virtual Server D to make necessary configurations and administration settings for the upcoming deployment of a new cloud service that was previously developed outside of Cloud X. Cloud Service Consumer B has been accessing Ready-Made Environment A to develop and now deploy a different new cloud service. Cloud Provider X (which is represented by a separate IT department dedicated to governing and administering Cloud X) determines that it will need to introduce three specific enhancements to Cloud X in order to accommodate both upcoming cloud services. First, it needs to add a way to charge cloud consumers for the usage of cloud services. Secondly, it needs to add a way for new cloud services to be automatically scaled. Finally, it needs to add a way for a cloud consumer to be automatically notified when a cloud service encounters runtime loads that exceed its allocated usage threshold. Which of the following statements accurately describes a solution that fulfills all three identified requirements?
Cloud Service A is being made available on public Cloud X by Cloud Provider X via the SaaS delivery model. Cloud Service A is hosted by Physical Server A that also hosts cloud services being used by different cloud service consumers (and owned by different cloud service owners). Cloud Provider X needs to make Cloud Service A available to a new group of cloud service consumers, but must do so without the increase in usage volume affecting Cloud Service Consumers A and B .
Which of the following statements does not accurately describe a solution (or a set of solutions) that addresses this requirement?
