NEW QUESTION # 36
What are the two disadvantages of implementing Query Caching?

A. Reduction in BI server processing time
B. Cache results being old
C. Needs a lot of administrators' time
D. Increased network traffic
E. Storage space for cache

Answer: B,E

Explanation:
B: The problem with caching of any kind is how to deal with stale data. How you decide to deal with this depends on how time critical your business intelligence queries happen to be. OBIEE provides a wide variety of mechanisms for dealing with stale data. The cache can be purged automatically at intervals. Caching can be enabled selectively for individual physical tables, so that data in a frequently updated table is never cached. OBIEE provides a set of ODBC procedures that can be called when ETL processes complete to programmatically purge designated tables. But, by far the best way to selectively purge the cache is to use an event polling table. This table is populated by the client database whenever changes are made to any table (by an ETL process for a data warehouse or by a table-based trigger for an OLTP database). At specified intervals the BI Server polls this event polling table and deletes from its cache any query results that are dependent on the changed data.

NEW QUESTION # 37
A customer has a requirement for rolling period calculations. What two additional steps will need to be done to enable this in the repository?

A. Clicking the "Time" option in the LogicalTable Source Dialog
B. Designatingachronological key for every level of every dimension hierarchy
C. Clicking the "Time" option in theLogical Dimension Dialog
D. Specifying a sort order in theLogicalTable dialog
E. Designating a chronological keyfor every logical column in the Logical Table Source

Answer: B,C

Explanation:
Creating Logical Time Dimensions
Compared to modeling an ordinary dimension, the time dimension requires just two additional
steps: selecting the Time option in the Logical Dimension dialog, and designating a chronological
key for every level of every dimension hierarchy.
Note: Time dimensions and chronological keys. You can identify a dimension as a time dimension.
At least one level of a time dimension must have a chronological key. The following is a list of
some guidelines you should use when setting up and using time dimensions:
*At least one level of a time dimension must have a chronological key.
*All time series measures using the AGO, TODATE, and PERIODROLLING functions must be on
time levels. AGO, TODATE, and PERIODROLLING aggregates are created as derived logical
columns.

Intelligence Enterprise Edition. Working with Logical Dimensions

NEW QUESTION # 38

NEW QUESTION # 39
When creating Aggregate tables in the OBI repository by using the Aggregate Persistence Wizard, which two statements are true?

A. The Extraction Transformation and Loading process creates the aggregate tables.
B. The Aggregate Persistence Wizard enables you to automate the creation of physical aggregate tables and their corresponding objects in the repository.
C. The analyst must first write DML (Data Manipulation Language) scripts to create the aggregate table.
D. Job Manager can be used to run the Aggregate Persistence script.

Answer: B,D

Explanation:
B: The Aggregate Persistence Wizard automates the creation and initial population of aggregates, persists them in a back-end database and configures the BI Server metadata layer so that they're used when appropriate.
C: The wizard then shows me a preview of the script it's going to generate, and asks me if I want to create any more summaries. Here's how the preview script looks - note that it's not SQL, it's a script language that the BI Server understands and uses as the specification for an aggregation job, which it then turns into separate CREATE TABLE, INSERT ... SELECT and so on SQL statements, "optimized" for the particular back-end database platform.
Script example:
"ag_Items"
for "Seminar - Complete"."Items"("Quantity")
at levels ("Seminar - Complete"."Customerdim"."State", "Seminar - Complete"."Productdim"."Category",
"Seminar - Complete"."Timedim"."Year")
using connection pool "custdw"."CUSTDW_Pool"
in "custdw".."CUSTDW";
