IBM DB2 11.1 Advanced DBA for Linux, UNIX, and Windows — Question 36

Which of the following is designed for continuous availability, increased throughput of many concurrent short queries, and easy scalability?

Answer options

• A. DB2 HADR
• B. DB2 pureScale
• C. DB2 Express-C
• D. DS2 Database Partitioning Feature

Correct answer: B

Explanation

The correct answer, DB2 pureScale, is specifically designed to provide continuous availability and efficient handling of many concurrent short transactions, making it ideal for environments requiring scalability. In contrast, DB2 HADR focuses on high availability, DB2 Express-C is a free version with limitations, and the DS2 Database Partitioning Feature enhances performance through partitioning but does not inherently provide the same level of continuous availability or scalability.
