Question No: 34

Data can come from a large number and variety of source systems. Based upon the IBM Big Data amp; Analytics Reference Architecture which two statement are true when considering analytics on these data sources?

  1. Data federation has the best performance and allows in place analytics directly at the source systems.

  2. Activity data hubs manage consolidated information about past activity based on the decisions related to entities in a master data hub.

  3. Data marts contain a subset of data from various input sources across the enterprise that can be easily updated in real time to provide faster analytics.

  4. MapReduce processing does not require a schema when loading the data but does require an understanding of the data format prior to processing the data

  5. Customer and account data is consolidated under a master data hub. Whereas product, supplier and asset data are consolidated outside of a master data hub for better analytical efficiency.

Answer: B,C

Question No: 35

Question No: 37

Which in-memory database design point helps use main memory more efficiently?

  1. Single Instruction Multiple Data processing.

  2. Automatic and always-on data compression.

  3. Processing data using multiple processor cores.

  4. Organizing data according to columns rather than rows.

Answer: D

Question No: 38

Which two statements are true for row oriented databases?

  1. They are well suited for OLTP workloads which are more heavily loaded with interactivetransactions.

  2. They are not well suited for OLTP workloads which are more heavily loaded with interactivetransactions.

  3. They are self-indexing which makes use of less disk space compared to a columnar orienteddatabase system.

  4. They are ideal when many columns of a single row are required at the same time and when row-size is relatively small, as the entire row can be retrieved with a single disk read.

  5. It has advantages for data warehouses, customer relationship management systems, and other

adhoc inquiry systems where aggregates are computed over large numbers of similar data items.

Answer: A,C

Question No: 39

Using Brewer#39;s CAP theorem as a guide for choosing between alternative data storage technologies, which two distributed system properties does Apache HBase (part of Hadoop) guarantee?

  1. Consistency – all nodes see the same data at the same time.

  2. Concurrency control – correct results for concurrent operations.

  3. Atomicity – if one part of a transaction fails, the entire transaction fails.

  4. Partition tolerance – the system continues to operate despite arbitrary message loss.

  5. Availability – every request receives a response about whether it was successful or failed

Answer: A,C

Question No: 40

What is a use case example for the Transform Financial Processes business imperative?
