CLO-002 Practice Test 5 — 10 Questions

Question 1

You are migrating a legacy application to the cloud. The application requires an OS that is no longer supported by the provider. Which migration strategy is most appropriate?

Accepted Answer

Re-platforming. Re-platforming (lift, tinker, and shift) involves making targeted changes to the application or its runtime to take advantage of cloud capabilities — including moving to a supported OS or managed service. Since the legacy OS is unsupported, re-platforming lets you migrate while modernizing the OS/runtime, avoiding the security and support risks of re-hosting an unsupported platform.

Answer

Re-hosting (Lift and Shift)

Answer

Retaining

Answer

Retiring

Question 2

When evaluating a cloud service provider (CSP), which TWO of the following business-focused documentation should be requested to verify the vendor's reliability and security posture?

Accepted Answer

SOC 2 Type II reports. Option C, SOC 2 Type II reports, is correct because they are independent audit attestations covering the Trust Services Criteria (security, availability, processing integrity, confidentiality, and privacy) over a defined review period, giving direct evidence of the vendor's security controls and operational reliability. Option E, Service Level Agreement (SLA) documentation, is correct because it contractually defines measurable commitments such as uptime percentage, availability targets, performance metrics, and remedies or credits for failures, which is exactly what a business needs to assess vendor reliability. The unmarked options do not belong: A, the quarterly stock earnings report, reflects financial market performance rather than security posture or service reliability; B, employee payroll records, is confidential HR data irrelevant to security evaluation and would raise privacy concerns; and D, internal office floor plans, is physical layout information with no bearing on the CSP's security or reliability assurances.

Answer

The provider's quarterly stock earnings report

Answer

Employee payroll records

Answer

Internal office floor plans

Question 3

A global company needs to ensure compliance with GDPR. Which feature of a cloud provider is most critical for compliance?

Accepted Answer

Data residency controls. GDPR requires that personal data of EU residents be stored and processed under specific legal frameworks, and data residency controls let organizations pin data to specific geographic regions (e.g., EU-West) to satisfy these requirements. This is the most critical cloud feature for GDPR compliance because it directly addresses the regulation's data sovereignty and cross-border transfer rules. Without residency controls, data may be replicated or processed outside approved jurisdictions, creating legal exposure.

Answer

Auto-scaling groups

Answer

Multi-region replication

Answer

Public IP addresses

Question 4

Which THREE of the following tools or methods are used to secure data in transit in the cloud?

Accepted Answer

TLS 1.2/1.3. TLS 1.2/1.3 (A) is correct because it encrypts application-layer traffic such as HTTPS, securing data as it moves between clients and cloud services. Direct Connect with MACsec (B) is correct because MACsec provides IEEE 802.1AE link-layer encryption on dedicated AWS Direct Connect connections, protecting data in transit over the private network path. VPN Tunnels using IPsec (E) are correct because IPsec encrypts and authenticates IP packets across untrusted networks, securing site-to-site or client-to-cloud transit. Server-side encryption at rest (C) is incorrect because it protects stored data on disks, not data moving across a network. User access logs (D) are incorrect because they record activity for auditing and monitoring but do not encrypt or otherwise secure data in transit.

Answer

Server-side encryption at rest

Answer

User access logs

Question 5

An organization runs a containerized e-commerce platform on a managed Kubernetes service. During a flash sale, response times degrade sharply. Metrics show the application pods are healthy and the database is not saturated, but the cluster reports that some nodes cannot schedule new pods because of resource pressure. The team must add capacity automatically when pod demand rises and remove it when demand falls. Which action should the team take?

Accepted Answer

Enable the cluster autoscaler so the node pool grows and shrinks with pending pod demand. The cluster autoscaler is designed for exactly this situation: it detects pods that are pending because no node has enough allocatable resources, then adds nodes to the pool, and later removes underutilized nodes when demand subsides. Because the workload pods are already healthy and the database is not the bottleneck, the missing piece is automatic node-level capacity, which this component supplies.

Answer

Configure a horizontal pod autoscaler to increase the replica count based on CPU utilization

Answer

Increase the CPU request and limit values on the existing application deployment

Answer

Create a pod disruption budget to guarantee minimum availability during scaling events

Question 6

Which cloud service model is best suited for end-users who want to use software via a browser?

Accepted Answer

SaaS. SaaS (Software as a Service) delivers fully managed applications to end-users over the internet, typically accessed through a browser without any installation or infrastructure management. Examples include Gmail, Salesforce, and Microsoft 365. This matches the question's description of end-users consuming software via a browser.

Answer

DaaS

Answer

IaaS

Answer

PaaS

Question 7

Which THREE are key characteristics of cloud computing?

Accepted Answer

Measured service. A. Measured service is correct because cloud providers meter resource usage (compute, storage, bandwidth) and bill customers based on consumption, enabling pay-as-you-go pricing. B. Broad network access is correct because cloud services are delivered over the network via standard mechanisms (e.g., HTTP/HTTPS, APIs) and accessible from diverse client devices such as laptops, phones, and tablets. E. Rapid elasticity is correct because cloud resources can scale out and in automatically or on demand to match workload changes, appearing nearly unlimited to the consumer. C. Static hardware provisioning is incorrect because cloud computing emphasizes dynamic, on-demand provisioning rather than fixed, pre-allocated hardware. D. Physical media access is incorrect because cloud services are accessed remotely over networks, not through physical media such as tapes, disks, or direct hardware connections.

Answer

Static hardware provisioning

Answer

Physical media access

Question 8

Which cloud principle refers to the ability to pay for only the compute power you consume?

Accepted Answer

Measured service. Measured service is the cloud principle that provides metering of resource usage, enabling pay-per-use billing. In this model, the cloud provider automatically monitors, controls, and reports resource consumption (e.g., compute hours, storage GB, data transfer), and customers are billed only for what they consume. This is distinct from on-demand self-service, which allows provisioning without human interaction, but does not inherently include metering. Thus, measured service directly supports the ability to pay only for the compute power used.

Answer

Rapid elasticity

Answer

Resource pooling

Answer

On-demand self-service

Question 9

A small marketing agency wants to move its customer relationship management (CRM) system to the cloud. The agency has limited IT staff and wants the provider to manage the operating system, middleware, and runtime, while the agency only manages its custom CRM application and data. Which cloud service model best fits this requirement?

Accepted Answer

Platform as a Service (PaaS). PaaS provides a managed platform that includes the operating system, middleware, and runtime, leaving the customer responsible only for the application and data. This aligns with the agency's need to offload infrastructure management while retaining control over its custom CRM application. IaaS requires more customer management, SaaS removes application control, and FaaS is unsuitable for a full CRM system.

Answer

Software as a Service (SaaS)

Answer

Function as a Service (FaaS)

Answer

Infrastructure as a Service (IaaS)

Question 10

A compliance officer needs to generate a report showing all instances that are not compliant with a standard CIS benchmark. Which service should be used?

Accepted Answer

AWS Security Hub. AWS Security Hub aggregates and normalizes findings from services like AWS Config, Inspector, GuardDuty, and third-party tools, and it includes the AWS Foundational Security Best Practices and CIS AWS Foundations Benchmark standards. Running the CIS standard in Security Hub produces a consolidated compliance view showing which resources are non-compliant, which is exactly what the compliance officer needs. This makes Security Hub the right reporting layer.

Answer

AWS Config

Answer

AWS Systems Manager

Answer

AWS CloudTrail
