IBM Cloud Pak for Data v3.0 Solution Architect — Question 4

An AIX customer is purchasing two new POWER9 processor-based servers: each connected to its own DS8880 at different sites. The customer wants high availability with the least amount of downtime.
Which solution will satisfy the customer's requirements?

Answer options

• A. Combine PowerHA with DS8880 data replication capabilities for automated failover across the sites.
• B. Create dual VIOS on each POWER9 and double the total number of adapters in each machine.
• C. Use the DS8880 data replication capabilities to replicate the data across the sites. Configure PowerVM Live Partition Mobility for application availability.
• D. Use the DS8880 data replication capabilities to perform automated node failover across the sites.

Correct answer: B

Explanation

The correct answer is B because creating dual VIOS on each POWER9 server enhances redundancy and increases the number of adapters, which contributes to higher availability. Option A, while beneficial, doesn't provide the same level of redundancy as dual VIOS. Option C focuses on application availability but may not fully address the high availability requirement. Option D does not offer the same level of active redundancy as option B.
