NEW QUESTION # 23
Why does IBM Cloud Analytics Engine decouple compute and storage?
- A. Compute can be scaled but storage costs are fixed
- B. To achieve scale independently and control costs
- C. Compute can be scaled but not storage
- D. Storage can be scaled but not compute
Answer: B
Explanation:
IBM Cloud Analytics Engine decouples compute and storage to provide independent scaling and cost management capabilities. This approach allows organizations to scale compute resources (such as CPU and memory) separately from storage resources, optimizing both performance and cost.
Independent Scaling: Decoupling compute and storage means that users can scale the computational power (e.g., number of nodes, processing capabilities) independently of the storage capacity (e.g., data stored in IBM Cloud Object Storage). This is particularly useful in data analytics workloads where the compute requirements may vary significantly over time, but the storage requirements remain relatively constant.
Cost Control: By allowing compute and storage to be managed separately, users have greater flexibility to control costs. For example, users can increase compute power temporarily to handle a peak workload without the need to increase storage costs. Conversely, they can store large datasets without paying for unused compute capacity. This decoupling leads to a more cost-effective and efficient use of cloud resources.
Advantages in Cloud Environments: Decoupling compute and storage aligns with the best practices in modern cloud environments, where elasticity, scalability, and cost efficiency are paramount. It allows organizations to adapt quickly to changing business needs and workload demands, reducing overhead and improving resource utilization.

NEW QUESTION # 24
Which high availability strategy will result in a maximum of 4 nines (99.99%) of availability for an IBM Kubernetes Services cluster?
- A. A single worker node in a single availability zone in a single region
- B. Multiple worker nodes in at least three availability zones in a single region
- C. Multiple worker nodes in a single availability zone in a single region
- D. Multiple worker nodes in at least three availability zones in two or more regions
Answer: B
Explanation:
To achieve a high availability strategy with a target of four nines (99.99%) for an IBM Kubernetes Services cluster, you need to deploy multiple worker nodes across at least three availability zones within a single region. This configuration ensures that even if one or two zones experience failures, the cluster remains operational, thus meeting the 99.99% uptime objective.
High Availability in IBM Cloud Kubernetes Service: Deploying worker nodes across multiple availability zones provides redundancy and fault tolerance. By having at least three zones, the Kubernetes cluster can tolerate failures in up to two zones while still maintaining functionality.
Comparison of Options:
A (Single worker node in a single zone): Insufficient for high availability as any zone failure would result in downtime.
B (Multiple nodes in a single zone): Provides redundancy but still vulnerable to zone-wide outages, not meeting 99.99% uptime.
C (Multiple nodes in at least three zones across multiple regions): While this offers high availability, it exceeds the requirements stated for achieving 99.99% within a single region.
