Question 2

In cloud computing, what does 'elasticity' specifically refer to?

Accepted Answer

The automatic scaling of resources up or down based on demand

Answer

Elasticity is the dynamic provisioning and deprovisioning of cloud resources in real time to match fluctuating workload demands.

Question 3

Which cloud storage tier is most cost-effective for archiving data that is rarely accessed but must be retained for compliance purposes?

Accepted Answer

Cold archive storage

Answer

Cold archive storage offers the lowest per-GB cost at the expense of higher retrieval latency, making it ideal for compliance-driven long-term retention.

Question 4

What is the primary purpose of a Content Delivery Network (CDN) in cloud infrastructure?

Accepted Answer

To cache and serve content from edge locations closer to end users

Answer

CDNs distribute cached copies of content to geographically dispersed edge nodes, reducing latency and load on origin servers.

Question 5

An organization uses separate cloud accounts for development, staging, and production environments. This practice is best described as:

Accepted Answer
