CompTIA Cloud+ Practice Test

Which of the following is a key characteristic of cloud computing?

1. High latency connections

2. Limited access to applications

3. Resource pooling

4. Fixed capacity resources

The correct answer is: Resource pooling

Resource pooling is a fundamental characteristic of cloud computing because it allows multiple customers to share a pool of computing resources, such as storage, processing power, and network bandwidth, which can be dynamically allocated and reassigned based on demand. This approach enhances efficiency by optimizing resource utilization and providing scalability, which is one of the key advantages of cloud services. Customers benefit from the ability to access and utilize resources as needed without being constrained by physical limitations. In contrast, the other choices highlight limitations or drawbacks that are not representative of the cloud model. High latency connections would negatively affect performance and usability, which goes against the standards expected in cloud services. Limited access to applications contradicts the essence of cloud computing, which promotes accessibility from various devices and locations. Fixed capacity resources imply a static environment that lacks the flexibility to scale and adapt to varying workloads, which is antithetical to the dynamic nature of cloud computing designed to meet fluctuating demands efficiently.
