Domain 1: Describe Cloud Concepts (30 Questions)
1. What is the primary benefit of cloud computing?
,- A) High upfront capital expenditure
- B) Scalability and elasticity
- C) Limited global reach
- D) Requirement for on-premises hardware
- Answer: B
- Rationale: Cloud computing allows organizations to scale resources up or down based on demand (elasticity)
and scale out to meet growth (scalability) without large upfront hardware investments.
2. Which cloud model provides services over the internet and is available to anyone who wants to use them?
- A) Private cloud
- B) Public cloud
- C) Hybrid cloud
- D) Community cloud
- Answer: B
- Rationale: A public cloud is owned and operated by a third-party cloud service provider and delivered over the
internet, making it available to the general public.
3. A company wants to keep sensitive data on-premises but use the cloud for additional compute power during
peak seasons. Which cloud model is this?
,- A) Public cloud
- B) Private cloud
- C) Hybrid cloud
- D) Multi-cloud
- Answer: C
- Rationale: A hybrid cloud combines on-premises infrastructure (private cloud) with a public cloud, allowing data
and applications to be shared between them.
4. What is a key characteristic of the consumption-based model in cloud computing?
- A) You pay a fixed monthly fee regardless of usage.
- B) You pay only for the resources you consume.
- C) You must purchase hardware upfront.
- D) You are locked into a long-term contract.
- Answer: B
- Rationale: The consumption-based model, also known as pay-as-you-go, means you are billed only for the
resources you actually use, such as compute time or storage.
5. Which of the following is NOT a benefit of cloud computing?
, - A) High availability
- B) Increased agility
- C) Predictable, fixed costs
- D) Global reach
- Answer: C
- Rationale: Cloud computing typically offers variable, operational expenditure (OpEx) costs rather than
predictable, fixed capital expenditure (CapEx) costs. Costs can fluctuate based on usage.
6. What does the term "high availability" mean in the context of cloud computing?
- A) The system is available only during business hours.
- B) The system is designed to be operational and accessible with minimal downtime.
- C) The system is available in multiple languages.
- D) The system is free to use.
- Answer: B
- Rationale: High availability refers to a system's ability to remain operational and accessible for a very high
percentage of time, often backed by Service Level Agreements (SLAs).
7. Which cloud service model provides a platform for developing, running, and managing applications without the
complexity of building and maintaining the infrastructure?
