CLO-002 Practice Test 15 — 15 Questions

Question 1

A financial services firm is evaluating a move to Microsoft Azure. The CIO is concerned about vendor lock-in and wants to ensure the ability to move workloads between cloud providers in the future. Which factor should be prioritized in the cloud strategy to mitigate lock-in?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Using open standards and portable technologies. To mitigate vendor lock-in, organizations should prioritize open standards and portable technologies. These allow applications to be moved between cloud providers with less effort. Proprietary services, long-term contracts, and siloed multi-cloud approaches can increase dependency and hinder portability.

Answer

Negotiating a long-term contract with Azure for cost savings

Answer

Implementing a multi-cloud strategy with separate silos for each provider

Answer

Adopting proprietary Azure services for maximum performance

Question 2

A retail company is migrating its order-processing application to the cloud. The application experiences unpredictable traffic spikes during flash sales, and the finance team wants to avoid paying for idle capacity. The IT manager proposes a cloud deployment model where the provider manages the infrastructure and the company pays only for what it consumes. Which cloud characteristic best describes this financial benefit?

Accepted Answer

Measured service. Measured service is the cloud characteristic that enables pay-per-use billing by monitoring and reporting resource consumption. In this scenario, the retail company needs to avoid costs for idle capacity during unpredictable spikes, which is achieved through measured service. Rapid elasticity, resource pooling, and on-demand self-service are related but do not directly address the financial requirement.

Answer

On-demand self-service

Answer

Resource pooling

Answer

Rapid elasticity

Question 3

A retail company wants to move its customer-facing web application to the public cloud. The CIO is concerned about unpredictable monthly costs and wants to ensure the finance team can forecast expenses accurately. The application experiences steady traffic during business hours but spikes during seasonal sales. Which cloud pricing model should the company adopt to best balance cost predictability and scalability?

Accepted Answer

A hybrid model combining reserved instances for baseline load and on-demand for peak load. Combining reserved instances for baseline capacity with on-demand for peaks provides cost predictability for steady usage and flexibility for variable demand. This hybrid model addresses the CIO's concern about forecasting while ensuring the application can scale during seasonal spikes. It avoids the higher costs of pure on-demand and the rigidity of full reserved commitments.

Answer

Spot instances for the entire application

Answer

Reserved instances with a one-year commitment

Answer

On-demand pricing with auto-scaling enabled

Question 4

A healthcare company is evaluating a move to cloud-based collaboration tools. The IT director must present a business case that addresses both financial and non-financial factors. Which two factors should be included in the business case to demonstrate the full value of the migration? (Choose two.)

Accepted Answer

Potential reduction in capital expenditure on physical servers. A strong cloud business case balances financial gains with operational and strategic benefits. Scalability supports service quality during demand spikes, while reduced capital expenditure improves cash flow and budgeting. Together they show that the migration delivers both cost efficiency and business agility, which are central to the CompTIA Cloud Essentials+ business principles domain.

Answer

Reduced need for a disaster recovery plan

Answer

Guaranteed elimination of all data breaches

Answer

Ability to ignore industry regulations because the provider handles compliance

Question 5

A healthcare organization is migrating its patient records system to the cloud. The system stores protected health information (PHI) and must comply with HIPAA regulations. The organization's legal team is concerned about data sovereignty and wants to ensure that data remains within the United States. Which cloud characteristic should the organization verify with the cloud provider to address this concern?

Accepted Answer

Data residency. The healthcare organization must ensure that PHI remains within the United States to comply with HIPAA and data sovereignty rules. Data residency defines where data is physically stored, so verifying this with the provider directly addresses the legal team's concern. The other options relate to portability, deletion, or redundancy, which do not ensure geographic confinement.

Answer

Data portability

Answer

Data remanence

Answer

Data redundancy

Question 6

A small marketing agency is considering moving its customer relationship management (CRM) system to the cloud. The agency has a limited IT staff and wants to minimize upfront capital expenditure. The owner asks which cloud service model would allow the agency to use the CRM software without managing the underlying operating system, middleware, or runtime. Which model should be recommended?

Accepted Answer

Software as a Service (SaaS). SaaS is the correct choice because it provides a complete application managed by the provider, requiring no infrastructure or platform management from the customer. The marketing agency can use the CRM software immediately, with minimal IT involvement and no upfront capital costs. IaaS, PaaS, and FaaS would require the agency to manage some layers, which contradicts their constraints.

Answer

Functions as a Service (FaaS)

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Question 7

A healthcare organization is evaluating a move to the cloud for its electronic health record (EHR) system. The CIO is concerned about regulatory compliance, data sovereignty, and the ability to audit provider operations. The organization must ensure that the cloud provider meets strict healthcare regulations. Which two factors should be prioritized during the provider evaluation? (Choose two.)

Accepted Answer

Compliance certifications such as HIPAA and HITRUST. For a healthcare organization, compliance certifications and data residency guarantees are paramount to protect sensitive EHR data and meet legal requirements. HIPAA and HITRUST certifications confirm the provider's adherence to healthcare security standards, while data residency guarantees ensure compliance with data sovereignty laws. Other factors like marketing, network reach, and financials, while potentially relevant, do not directly address the CIO's stated concerns.

Answer

The provider's stock performance and financial stability

Answer

The number of global points of presence (PoPs)

Answer

The provider's marketing materials and analyst reports

Question 8

A financial services firm is planning to migrate its trading platform to the cloud. The CIO wants to ensure that the cloud environment can automatically adjust resources to handle sudden increases in trading volume without manual intervention, while maintaining performance. Which cloud characteristic is most critical to meet this requirement?

Accepted Answer

Rapid elasticity. Rapid elasticity is the cloud characteristic that enables automatic scaling of resources to match demand. For a trading platform facing sudden volume increases, this ensures performance is maintained without manual intervention. Measured service, resource pooling, and on-demand self-service are related but do not provide the automatic adjustment required.

Answer

On-demand self-service

Answer

Measured service

Answer

Resource pooling

Question 9

A mid-sized company is evaluating a move to the public cloud. The IT director wants to identify TWO key business benefits that directly support the company's goal of accelerating time-to-market for new products. Which TWO benefits should the director highlight? (Choose two.)

Accepted Answer

Elastic scalability to handle demand spikes. Rapid provisioning and elastic scalability are two cloud benefits that directly accelerate time-to-market. Rapid provisioning lets teams start building immediately, while elasticity ensures applications can handle variable loads without delays. These capabilities reduce the time from concept to production, enabling faster product launches. Other benefits like cost reduction or security are valuable but do not directly speed up product delivery.

Answer

Reduced capital expenditure on hardware

Answer

Increased control over physical security

Answer

Fixed monthly pricing for all services

Question 10

When evaluating cloud providers, what is the significance of the 'Region' concept?

Accepted Answer

Meeting data residency and sovereignty requirements. A cloud 'Region' is a geographic area containing one or more data centers (availability zones) that are isolated from other regions. The primary significance for compliance is that data stored in a region remains within that jurisdiction, helping organizations meet data residency, sovereignty, and regulatory requirements such as GDPR or HIPAA.

Answer

Increasing the number of available users

Answer

Automating security updates

Answer

Reducing service cost

Question 11

A small business is considering moving its email and file sharing to a cloud-based productivity suite. The owner is concerned about vendor lock-in and wants to understand the exit strategy. Which factor is most important to evaluate before signing the contract?

Accepted Answer

The provider's data portability and export capabilities. Data portability and export capabilities are essential for avoiding vendor lock-in. They allow the business to migrate to another provider with minimal disruption and cost. Before signing, the owner should verify that email and files can be exported in standard formats and that the provider's terms do not restrict such transfers. This due diligence supports a viable exit strategy.

Answer

The availability of a mobile app for the service

Answer

The number of data centers the provider operates globally

Answer

The provider's stock price and financial stability

Question 12

When following the Shared Responsibility Model, which security aspect is the customer's responsibility in an IaaS environment?

Accepted Answer

Guest OS patching. In the Shared Responsibility Model for IaaS, the customer is responsible for everything from the guest OS upward, including patching the guest operating system, middleware, runtime, applications, and data. The cloud provider manages the physical hosts, hypervisor, network, and data center. Guest OS patching is therefore squarely the customer's duty in IaaS.

Answer

Hypervisor security

Answer

Physical security of the data center

Answer

Host OS patching

Question 13

A startup is calculating the ROI for a migration project. They have calculated the Total Cost of Ownership (TCO) savings. What secondary financial factor must be included to accurately determine the overall ROI of the cloud adoption?

Accepted Answer

Initial migration and training costs. To calculate ROI accurately for a cloud migration, you must include not only ongoing TCO savings but also the one-time costs required to realize those savings — specifically initial migration costs (data transfer, refactoring, tooling) and training costs for staff. These upfront investments reduce net benefit and therefore directly affect the ROI calculation.

Answer

Current on-premises electricity costs

Answer

Projected marketing revenue

Answer

Cloud provider's stock price

Question 14

A developer needs a serverless environment to run event-driven code. What should they choose?

Accepted Answer

FaaS (e.g., Lambda). FaaS (Function-as-a-Service), such as AWS Lambda, Azure Functions, or Google Cloud Functions, is the serverless model purpose-built for event-driven code: the platform provisions compute on demand, scales automatically, and bills per invocation. The developer uploads a function, binds it to an event source (HTTP, queue, object storage), and never manages servers.

Answer

Managed Kubernetes

Answer

Elastic Compute Cloud

Answer

Relational Database

Question 15

A developer needs a storage solution for high-frequency trading logs that must be instantly accessible for analysis, with high IOPS, and low latency. Which storage type is most appropriate?

Accepted Answer

Block Storage. Block storage (e.g., AWS EBS, Azure Managed Disks) provides raw, low-latency, high-IOPS volumes attached to a single compute instance, making it the right choice for high-frequency trading logs that demand instant access and consistent performance. It behaves like a local disk, so databases and latency-sensitive workloads run directly against it without the overhead of network file protocols or object APIs.

Answer

Archive Storage

Answer

File Storage

Answer

Object Storage
