CompTIA Cloud Computing Fundamentals 2 — Questions and Answers
Question 1: Which cloud concept refers to the ability to access cloud services over the network using standard mechanisms from any device such as laptops, tablets, and smartphones?
- Resource pooling
- Broad network access (Correct answer)
- On-demand self-service
- Rapid elasticity
Correct answer: Broad network access
Broad network access means capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms.
Question 2: What is a key security concern unique to cloud computing environments compared to traditional on-premises deployments?
- Physical server failure
- Lack of antivirus software
- Data sovereignty and multi-tenancy risks (Correct answer)
- Hardware procurement delays
Correct answer: Data sovereignty and multi-tenancy risks
In cloud environments, data may reside in multiple geographic regions and share physical resources with other tenants, raising concerns about data sovereignty and isolation.
Question 3: A business is evaluating cloud providers and wants to ensure workloads can be moved between providers without significant rework. What term describes this ability?
- High availability
- Cloud bursting
- Vendor lock-in avoidance / portability (Correct answer)
- Elasticity
Correct answer: Vendor lock-in avoidance / portability
Cloud portability refers to the ability to move applications and data between different cloud providers with minimal effort, reducing dependency on a single vendor.
Question 4: Which virtualization component acts as the software layer that creates and manages virtual machines by abstracting physical hardware resources?
- Virtual NIC
- Hypervisor (Correct answer)
- Container runtime
- Orchestrator
Correct answer: Hypervisor
A hypervisor (VMM) sits between physical hardware and virtual machines, abstracting and allocating hardware resources to multiple VMs running simultaneously.
Question 5: What is the primary difference between a Type 1 (bare-metal) hypervisor and a Type 2 (hosted) hypervisor?
- Type 1 runs on top of a host OS; Type 2 runs directly on hardware
- Type 1 runs directly on hardware; Type 2 runs on top of a host OS (Correct answer)
- Type 1 supports only Windows VMs; Type 2 supports all OS types
- Type 1 is software-based; Type 2 is hardware-based
Correct answer: Type 1 runs directly on hardware; Type 2 runs on top of a host OS
A Type 1 hypervisor runs directly on physical hardware for better performance and efficiency, while a Type 2 hypervisor runs on top of an existing operating system.
Question 6: Which cloud storage type is best suited for storing large amounts of unstructured data such as images, videos, and backups in a flat namespace?
- Block storage
- File storage
- Object storage (Correct answer)
- Archive storage
Correct answer: Object storage
Object storage stores data as discrete objects with metadata and unique identifiers in a flat namespace, making it ideal for large-scale unstructured data like media files and backups.
Question 7: A company uses multiple public cloud providers simultaneously to avoid vendor lock-in and optimize performance. What strategy is this?
- Hybrid cloud
- Multicloud (Correct answer)
- Community cloud
- Cloud bursting
Correct answer: Multicloud
A multicloud strategy involves using services from two or more public cloud providers to leverage best-of-breed features and avoid dependency on any single provider.
