CLO-002 Practice Test 6 — 10 Questions

Question 1

Which of the following represents a major benefit of cloud computing where resources are shared among multiple customers?

Accepted Answer

Resource pooling. Resource pooling is the multi-tenant cloud characteristic where compute, storage, and network resources are shared among many customers from a pooled infrastructure, with dynamic assignment based on demand. This sharing drives economies of scale and cost efficiency, which is the benefit described in the question.

Answer

Local area networking

Answer

Static provisioning

Answer

Dedicated hosting

Question 2

You are tasked with automating a script that runs every night at 2 AM to clean up temporary files. Which service is most appropriate for triggering this task?

Accepted Answer

AWS Lambda + EventBridge. AWS Lambda combined with Amazon EventBridge is the canonical serverless pattern for scheduled tasks. EventBridge (formerly CloudWatch Events) supports cron and rate expressions, so a rule like 'cron(0 2 * * ? *)' triggers the Lambda function nightly at 2 AM. Lambda executes the cleanup code without requiring a persistent EC2 instance, making it cost-effective and operationally simple.

Answer

AWS SNS

Answer

AWS IAM

Answer

AWS SQS

Question 3

A software development team is using a cloud-based platform that provides a runtime environment, middleware, and database services. The team can deploy their code without managing the underlying operating system or servers. However, they are responsible for configuring the application and its data. Which cloud service model is the team using?

Accepted Answer

Platform as a Service (PaaS). PaaS provides a complete development and deployment environment in the cloud, including runtime, middleware, and database services. The team can deploy code without managing the OS or servers, and they remain responsible for their application and data. This aligns with the PaaS model, where the provider manages the platform and the customer manages the application.

Answer

Function as a Service (FaaS)

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Question 4

A security analyst notices unauthorized changes to cloud infrastructure. Which service should be analyzed to identify which IAM user made the changes?

Accepted Answer

AWS CloudTrail. AWS CloudTrail records API activity across the account, including the identity of the caller (IAM user, role, or federated identity), the action taken, the resource affected, source IP, and timestamp. Analyzing CloudTrail event history lets the analyst pinpoint exactly which IAM user made unauthorized infrastructure changes. This is the authoritative audit log for 'who did what' in AWS.

Answer

AWS IAM Access Analyzer

Answer

AWS CloudWatch

Answer

AWS Security Hub

Question 5

A company is preparing for a cloud migration and needs to ensure compliance with the General Data Protection Regulation (GDPR). The compliance team has identified several requirements. Which TWO of the following are the company's responsibilities under the shared responsibility model when using a public cloud? (Choose two.)

Accepted Answer

Classifying data based on sensitivity and regulatory requirements. Under the shared responsibility model, the customer is responsible for data classification and IAM configuration, as these are directly related to how data is handled and accessed. The provider is responsible for physical security and hypervisor patching. Key management can be shared, but the two clear customer responsibilities are data classification and IAM policies.

Answer

Patching the hypervisor that hosts virtual machines

Answer

Managing the lifecycle of encryption keys stored in a hardware security module (HSM)

Answer

Ensuring physical security of data center facilities

Question 6

You want to receive an email alert whenever your monthly cloud spending exceeds $500. Which service should you configure?

Accepted Answer

AWS Budgets. AWS Budgets allows you to set custom budgets for cost, usage, or reservations, and configure alerts when actual or forecasted spending exceeds a defined threshold. You can specify a monthly cost budget of $500 and attach an email notification to be triggered when actual spend surpasses that amount. This is the native AWS service designed for proactive cost monitoring and alerting, making it the correct choice for receiving an email alert on monthly spending.

Answer

AWS Cost Explorer

Answer

AWS Trusted Advisor

Answer

AWS CloudTrail

Question 7

A company is moving from a capital expenditure model to an operational expenditure model. What is the primary benefit?

Accepted Answer

Removal of upfront capital costs. The primary benefit of moving from CapEx to OpEx is the elimination of large upfront capital investments. In a CapEx model, a company must purchase hardware and infrastructure outright, which requires significant capital outlay and depreciates over time. In an OpEx model, such as with cloud services, the company pays for what it uses on a subscription or pay-as-you-go basis, converting that large upfront cost into smaller, recurring operational expenses. This improves cash flow and allows the company to scale resources up or down as needed without being locked into a long-term asset.

Answer

Increased control over hardware

Answer

Predictable monthly billing

Answer

No hardware maintenance

Question 8

A small marketing agency wants to move its client project files to a cloud storage solution. The agency has unpredictable storage needs, wants to avoid purchasing hardware, and requires access from Windows, macOS, and mobile devices. Which cloud characteristic best describes the agency's ability to provision storage on demand without human intervention from the provider?

Accepted Answer

On-demand self-service. On-demand self-service is the cloud characteristic that lets a consumer provision resources such as storage automatically, without human interaction with the provider. The agency can use a portal or API to allocate storage immediately, which suits unpredictable needs and avoids hardware purchases. Broad network access, rapid elasticity, and resource pooling are separate characteristics that do not directly address unassisted provisioning.

Answer

Broad network access

Answer

Rapid elasticity

Answer

Resource pooling

Question 9

Which document is essential for cloud vendor selection and outlines specific performance, security, and financial requirements?

Accepted Answer

Request for Proposal (RFP). A Request for Proposal (RFP) is a formal document issued to potential vendors that specifies the organization's performance, security, financial, and functional requirements, and asks vendors to respond with proposed solutions and pricing. It is the standard procurement artifact used to evaluate and select a cloud vendor against defined criteria. This makes it essential for vendor selection.

Answer

Service Level Agreement (SLA)

Answer

Public cloud price list

Answer

Marketing brochure

Question 10

A project manager is calculating the cloud adoption strategy using a 'Re-platform' approach. What is the expected outcome?

Accepted Answer

Optimize application performance by migrating to managed services. Re-platform (often called 'lift, tinker, and shift') involves making a few cloud optimizations to the existing application without changing its core architecture. The most common form is migrating from self-managed infrastructure to managed cloud services — for example, moving a self-hosted MySQL database to Amazon RDS or a self-managed message broker to Amazon MQ. This preserves the application's functionality while gaining managed-service benefits like automated backups, patching, and scaling.

Answer

Moving VMs without any changes

Answer

Replacing the application with a third-party service

Answer

Complete rewrite of the application code
