CLO-002 Practice Test 4 — 10 Questions

Question 1

A multinational retailer must keep customer records in the country where they were collected. The company uses a cloud provider with regions in North America, Europe, and Asia. Which configuration most directly enforces this data residency requirement?

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

Accepted Answer

Deploy the database and its backups in the region corresponding to each customer's country and disable cross-region replication.. Data residency is enforced by controlling the physical location of storage, including replicas and backups. Deploying the database and its backups in the country of collection and disabling cross-region replication keeps every copy of the record within the required jurisdiction, which is the only configuration among the choices that directly enforces the requirement.

Answer

Use a cloud access security broker to inspect data in transit between regions.

Answer

Enable geo-restriction at the content delivery network edge for all customer traffic.

Answer

Apply resource tags indicating the customer's country and use them in cost allocation reports.

Question 2

Which THREE of the following are necessary to manage multi-cloud deployments effectively?

Accepted Answer

Unified monitoring tools. Unified monitoring tools (B) are necessary because multi-cloud deployments span AWS, Azure, and GCP, so a single pane of glass aggregating metrics, logs, and traces across providers is required to detect issues and maintain consistent observability. Infrastructure as Code (D) is essential because declarative templates (e.g., Terraform, CloudFormation, ARM/Bicep) let you provision and version identical, repeatable environments across heterogeneous clouds, avoiding manual drift. Centralized identity management (E) is required to federate authentication and authorization across providers using standards like SAML 2.0 or OIDC, so users and service accounts have one consistent identity and RBAC policy set rather than per-cloud silos. Ignoring one cloud provider (A) is wrong because it defeats the purpose of multi-cloud management and leaves resources ungoverned, while printing physical logs (C) is neither scalable nor a real management practice compared with centralized log aggregation.

Answer

Ignoring one cloud provider

Answer

Printing physical logs

Question 3

Which cloud service model would best suit a company that needs complete control over the network configuration and operating system but wants to avoid physical server maintenance?

Accepted Answer

IaaS. IaaS provides virtualized computing resources over the internet, giving the customer control over the operating system, storage, and network configuration while the provider manages the physical infrastructure. This matches the requirement for complete control over network and OS without physical server maintenance.

Answer

PaaS

Answer

SaaS

Answer

Serverless

Question 4

You are managing a multi-cloud environment using Terraform. You need to ensure that the infrastructure state is locked to prevent concurrent modifications during CI/CD pipeline runs. Which backend component should you implement to achieve state locking?

Accepted Answer

DynamoDB table. DynamoDB is the standard remote backend component for Terraform state locking when using the S3 backend. Terraform writes a lock item to a DynamoDB table (specified via the dynamodb_table argument in the backend block) before any state-modifying operation, and releases it afterward. This prevents two CI/CD pipeline runs from concurrently applying changes and corrupting the state file.

Answer

S3 Versioning

Answer

Terraform Cloud Workspaces

Answer

IAM Policy

Question 5

A cloud operations team wants to automatically remediate an EC2 instance that has been running with CPU utilization below 5% for 14 consecutive days. The team needs the remediation to trigger without manual intervention and to notify a Slack channel. Which AWS service should be used to orchestrate this workflow?

Accepted Answer

AWS Systems Manager Automation. The requirement is an event-driven, multi-step remediation that stops an underutilized instance and notifies a channel without human action. Systems Manager Automation provides runbooks that can be triggered by CloudWatch alarms or EventBridge rules, execute API calls, and integrate with notification services. The other services either only assess compliance, only provision infrastructure, or only give recommendations, so none can orchestrate the full workflow autonomously.

Answer

AWS Trusted Advisor

Answer

AWS Config

Answer

AWS CloudFormation

Question 6

You need to store audit logs that are immutable and cannot be deleted for a set period. Which feature should you enable?

Accepted Answer

Object Lock. S3 Object Lock enforces WORM (Write Once, Read Many) semantics, preventing objects from being deleted or overwritten for a specified retention period. It is the correct feature for immutable audit logs that must be preserved for compliance. Object Lock requires S3 Versioning to be enabled on the bucket and is configured in Governance or Compliance mode.

Answer

Access Logs

Answer

Versioning

Answer

Encryption

Question 7

A company uses a hybrid cloud. They need to move a database workload to the cloud that has strict regulatory requirements. Which deployment model is most appropriate?

Accepted Answer

Private cloud deployment. Private cloud deployment is correct because strict regulatory requirements (e.g., PCI-DSS, HIPAA, GDPR data residency, FedRAMP) often mandate dedicated infrastructure, full control over data location, and isolation from other tenants. A private cloud provides single-tenant hardware and network, enabling the organization to meet compliance controls around data sovereignty, access, and auditing that multi-tenant public clouds may not satisfy without extensive additional controls.

Answer

Public cloud multi-tenant

Answer

Community cloud

Answer

Serverless functions

Question 8

A retail company is using a public cloud provider. The IT manager wants to understand how the cloud provider's use of shared physical resources affects the company's data. Which cloud characteristic ensures that the provider's other customers cannot access the retail company's data?

Accepted Answer

Multi-tenancy with logical isolation. Multi-tenancy with logical isolation is the cloud characteristic that allows multiple customers to share physical resources while keeping their data separate. The provider uses virtualization, network segmentation, and access controls to ensure that one tenant cannot access another's data. Elasticity, measured service, and on-demand self-service are important cloud traits but do not provide the security isolation required.

Answer

Measured service

Answer

On-demand self-service

Answer

Elasticity

Question 9

A cloud administrator is tasked with reducing idle resource costs in AWS. Which tool should be configured to provide specific rightsizing recommendations for EC2 instances based on historical utilization data?

Accepted Answer

AWS Compute Optimizer. AWS Compute Optimizer analyzes historical CloudWatch metrics (CPU, memory if the agent is installed, network, disk) and applies machine-learning models to generate specific rightsizing recommendations for EC2 instances, including over-provisioned and under-provisioned findings. It is purpose-built for this task and integrates with Cost Explorer and Trusted Advisor.

Answer

AWS Cost Explorer

Answer

AWS Trusted Advisor

Answer

AWS Budgets

Question 10

Which technology is primarily used to isolate applications while sharing the same OS kernel?

Accepted Answer

Containers. Containers share the host OS kernel and use Linux primitives like namespaces (for isolation of process, network, mount, PID views) and cgroups (for resource limits) to isolate applications from each other. Because they do not bundle a full OS, containers are lightweight and start in milliseconds, unlike VMs which each run their own kernel. This kernel-sharing model is the defining characteristic that distinguishes containers from virtual machines.

Answer

Bare Metal

Answer

Virtual Machines

Answer

Hypervisors
