CompTIA Cloud+ CV0-004 Exam 2026 – 190 Practice Questions with
Answers & Detailed Rationales, Cloud Architecture, Security,
Deployment, Operations, Troubleshooting & DevOps Fundamentals
Domain 1: Cloud Architecture (Questions 1–44)
Question 1
Which cloud characteristic allows resources to be automatically provisioned and released
based on demand without human intervention?
A. Measured service
B. Rapid elasticity
C. Resource pooling
D. On-demand self-service
Correct Answer: B
Explanation: Rapid elasticity automatically scales resources up or down based on workload
demand, enabling dynamic provisioning without manual intervention in cloud environments.
Question 2
An organization requires a cloud model where the provider manages the runtime,
middleware, and operating system while the customer deploys only application code. Which
model satisfies this requirement?
A. IaaS
B. PaaS
C. SaaS
,D. DaaS
Correct Answer: B
Explanation: PaaS abstracts infrastructure and runtime management, leaving customers
responsible only for applications and data they deploy on the platform.
Question 3
A company must retain complete control over encryption keys for regulatory compliance.
Which key management approach should they implement?
A. Provider-managed keys
B. Customer-managed keys in a KMS
C. Hardcoded keys in application configuration
D. Default platform encryption only
Correct Answer: B
Explanation: Customer-managed keys in a key management service provide control,
revocation capability, audit trails, and rotation policies required by compliance frameworks.
Question 4
Which cloud deployment model combines on-premises infrastructure with public cloud
services for workload portability?
A. Private cloud
B. Community cloud
C. Hybrid cloud
D. Multi-cloud
,Correct Answer: C
Explanation: Hybrid cloud integrates on-premises infrastructure with public cloud resources,
enabling workload mobility and unified management across environments.
Question 5
A workload experiences predictable baseline traffic with unpredictable daily spikes. Which
provisioning strategy optimizes cost while maintaining performance?
A. Provision for peak capacity permanently
B. Provision baseline with committed discount and autoscale for spikes
C. Provision for average utilization
D. Provision minimum capacity only
Correct Answer: B
Explanation: Committed baseline captures discounts on predictable usage while autoscaling
handles bursts cost-effectively without overprovisioning idle capacity.
Question 6
Which storage type provides concurrent file-level access to multiple compute instances
simultaneously using standard protocols?
A. Block storage
B. Object storage
C. File storage (NFS/SMB)
D. Local ephemeral disk
, Correct Answer: C
Explanation: File storage supports concurrent access via NFS or SMB protocols, enabling
multiple instances to share hierarchical file systems simultaneously.
Question 7
A container orchestration platform must automatically replace failed containers to maintain
desired replica count. Which capability enables this?
A. Service mesh
B. Self-healing
C. Horizontal pod autoscaling
D. Ingress controller
Correct Answer: B
Explanation: Self-healing automatically detects and replaces failed containers, maintaining
declared replica counts without manual intervention in orchestration systems.
Question 8
What is the primary purpose of a content delivery network (CDN) in cloud architecture?
A. Encrypt data at rest
B. Reduce latency by caching content at edge locations
C. Provide identity federation
D. Automate infrastructure provisioning
Correct Answer: B
