NEW QUESTION # 32
An architect is tasked with determining the resiliency option for an application where the data must remain in-country and locally restricted.
Which IBM Cloud Object Storage resiliency option is best for this use case?
- A. Multizone
- B. Cross Region
- C. Cross Zone
- D. Single Data Center
Answer: D
Explanation:
The best IBM Cloud Object Storage resiliency option for a use case where data must remain in-country and locally restricted is Single Data Center.
Single Data Center: This option ensures that all data is stored within a single geographic location, which complies with regulations or requirements that mandate data residency within a specific country. By using a single data center, the data remains locally restricted.
Data Residency Requirements: When an application has strict regulatory or compliance requirements that specify data must not leave the country, the Single Data Center option ensures that data does not cross geographic boundaries.
Reference from IBM Cloud Professional Architect Materials:
IBM documentation on IBM Cloud Object Storage Resiliency Options states that the Single Data Center option is best suited for scenarios where data residency is a concern.
Other options are incorrect:
A . Cross Zone, C. Cross Region, and D. Multizone involve data being stored across multiple locations or regions, which would not meet the requirement of keeping the data locally restricted.

NEW QUESTION # 39
What is the main advantage of using IBM Code Engine over traditional server provisioning?
- A. Greater scalability
- B. Lower latency
- C. Higher security
- D. Better load balancing
Answer: A
Explanation:
The main advantage of using IBM Code Engine over traditional server provisioning is greater scalability.
