Q4. Which statement is true about the need to have a topology with an intermediate server, in order to use ODI correctly in a data warehouse project?(Choose the best answer.) 

A. Data transformation must be distributed across several scalable nodes. 

B. It is mandatory to have an intermediate server. 

C. It is better to load data directly from sources into a data warehouse server. 

D. It is mandatory to collect data directly from sources to a data warehouse server by using 

real time replication processes. 

Answer:

Q5. You are working with delimited flat files and want to enforce a primary key on a flat file by using a Check Knowledge Modules (CKM). However, you encounter an error. 

Why did this happen?(Choose the best answer.) 

A. It is not possible to enforce constraints on some technologies such as flat files and Java Messaging Service (JMS) queries. 

B. It is not possible to enforce constraints on any technology. 

C. It is only possible to forward-engineer it to the flat file definition. 

D. It is possible to enforce a primary key on a flat file by using a CKM; however, you have to save it as a fixed file.

Q6. Which statement is true about theIKM SQL Control Append thatcreates an intermediate integration table prefixed with I$?(Choose the best answer.) 

A. Theintermediate integration table prefixed with I$is required to determine which records must be inserted. 

B. IfFlow Control is not necessary, an I$ table is not created. 

C. Theintermediate integration table prefixed with I$ is createdbecause the flow control is mandatory when doing an initial load. 

D. Neither the LKM northe IKM create intermediate tables. Most of their work is performed in the ODI Agent memory.

Q9. You want to draw directly in the data flow all the details about how the different servers involved are connected, in order to load a specific table by using ODI. 

What must you do to accomplish this?(Choose the best answer.) 

A. In the ODI Interface palette, choose the more convenient graphic objects to link the involved servers. 

B. You need not draw directly in the data flow all the details about how the different servers involved are connected. ODI automatically designs the flow and how servers are connected. 

C. You need not draw directly in the data flow all the details about how the different servers involved are connected. The code will be the black box generated directly by ODI. 

D. You must draw directly in the data flow all the details about how the different servers involved are connected, and also specify with variables the passwords for connecting to the data contained in the servers. 

Answer:

Q10. Your package logic requires you to retrieve the status of the previous package step into a variable. How must you implement this?(Choose the best answer.) 

A. Create a variable, useodiRef.getPrevStepLog ()in the SQL query in its Refreshing tab, and add a variable as a Refresh Variable step into the package. 

B. Create a variable, useodiRef.getPrevInfo ()in the SQL query in its Refreshing tab, and add a variable as a Refresh Variable step into the package. 

C. Create a variable, useodiRef.getStep ()in the SQL query in its Refreshing tab, and add a variable as a Refresh Variable step into the package. 

D. Create a variable, useodiRef.getPrevStepStatus ()in the SQL query in its Refreshing tab, and add a variable as a Refresh Variable step into the package.
