a.

Fact tables first, then dimension tables

b.

Simultaneously

c.

Dimension tables first, then fact tables

d.

Fact tables only

Discuss
Answer: (c).Dimension tables first, then fact tables Explanation:Dimension tables are loaded first, followed by fact tables, during the complete initial load of a data warehouse.
Q14.
When are aggregate tables created during the complete initial load of a data warehouse?

a.

Before loading dimension and fact tables

b.

After building indexes

c.

Simultaneously with the creation of load images in the staging area

d.

Based on an already established plan, either before or after the creation of load images in the staging area

Discuss
Answer: (d).Based on an already established plan, either before or after the creation of load images in the staging area Explanation:Aggregate tables are created during the complete initial load of a data warehouse based on an already established plan, either before or after the creation of load images in the staging area.
Q15.
What should be done after building indexes during the complete initial load of a data warehouse if referential integrity was not suspended?

a.

Restart the entire load process

b.

Examine the log files for referential violations and resolve them

c.

Suspend referential integrity at this stage

d.

Avoid the creation of aggregate tables

Discuss
Answer: (b).Examine the log files for referential violations and resolve them Explanation:After building indexes during the complete initial load of a data warehouse, if referential integrity was not suspended, the log files should be examined for referential violations, and they should be resolved.
