NEW QUESTION # 40
When evaluating different site strategies for an application's resiliency in IBM Cloud, which describes the concept of local resiliency?
- A. Ability of a site strategy to withstand physical events such as natural disasters and power outages
- B. Practice of maintaining multiple copies of data across geographically dispersed sites to ensure redundancy and data availability
- C. Using a separate zone within a region that has independent power supply, cooling, and networking
- D. Process of regularly testing and validating the effectiveness of a site strategy to mitigate potential risks
Answer: C
Explanation:
Local resiliency in IBM Cloud refers to using a separate zone within the same region that has its own independent power supply, cooling, and networking. This approach provides redundancy within a single geographical region, ensuring that if one zone fails due to a localized event, other zones can continue to operate without interruption.
Local Resiliency Definition: By deploying resources in separate zones within the same region, clients achieve local resiliency that protects against localized failures such as power outages or hardware failures affecting only one zone.
Why This is Considered Local Resiliency: It offers redundancy and fault tolerance without requiring resources to be spread across multiple regions, reducing latency and providing a balance between availability and performance.
Comparison with Other Options:
A (Physical events): Describes regional or global resiliency.
B (Multiple copies of data across sites): Refers to data redundancy, which is different from local resiliency.
C (Testing site strategy): Focuses on testing rather than a strategy for resiliency.
