A.   Tier 5 storage

Answer DescriptionExplanation:

For storing data for long-term archival purposes with a minimal I/O load and a peak IOPS requirement of 50,Tier 5 storageis the most appropriate choice.

Tier 5 Storage: This storage tier is designed for workloads with low performance and IOPS requirements, such as long-term data archival or infrequently accessed data. Tier 5 offers the lowest cost option and is ideal for scenarios where data is rarely accessed, and there is a minimal input/output operation per second (IOPS) requirement.

Workload Suitability: Given that the workload described involves minimal I/O load and a peak IOPS requirement of 50, Tier 5 provides an optimal balance between cost and the minimal performance needed for such an archival workload.

References from IBM Cloud Professional Architect Materials:

IBM documentation on IBM Cloud Storage Tiers indicates that Tier 5 storage is suitable for long-term data storage and archival, where performance requirements are minimal.

Other options are incorrect:

B. Tier 2 storage,C. Tier 3 storage, andD. Tier 1 storageprovide higher performance than necessary for the described archival workload, resulting in potentially unnecessary costs.

D.   Using a separate zone within a region that has independent power supply, cooling, and networking

Answer DescriptionExplanation:

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.
