1. Identify two items that are created as a result of running a Balanced Optimization on a job that accesses a Hadoop distributed file system as a source? (Choose two.)
A) A JAQL stage is found in the optimized job result.
B) A MapReduce Transformer stage is found in the optimized job result.
C) A Balanced Optimization Shared Container is found in the project.
D) A Balanced Optimization parameter set is found in the project
E) A Big Data File stage is found in the optimized job results.
2. Identify two restructure stages that allow you to create or organize vectors in the output link results? (Choose two.)
A) Make Subrecord
B) Column Import
C) Split Vector
D) Merge records
E) Split Subrecord
3. Rows of data going into a Transformer stage are sorted and hash partitioned by the Input.Product column. Using stage variables, how can you determine when a new row is the first of a new group of Product rows?
A) Create a stage variable named sv_IsNewProduct and follow it by a second stage variable
named sv_Product. Map the Input.Product column to
sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product = sv_Product THEN "YES"
ELSE "NO".
B) Create a stage variable named sv_IsNewProduct and follow it by a second stage variable
named sv_Product. Map the Input.Product column to
sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product <> sv_Product THEN "YES"
ELSE "NO".
C) Create a stage variable named sv_Product and follow it by a second stage variable named
sv_IsNewProduct. Map the Input.Product column to
sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product = sv_Product THEN "YES"
ELSE "NO".
D) Create a stage variable named sv_Product and follow it by a second stage variable named
sv_IsNewProduct. Map the Input.Product column to
sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product <> sv_Product THEN "YES"
ELSE "NO".
4. You are responsible for deploying objects into your customers production environment. To ensure the stability of the production system the customer does not permit compilers on production machines. They have also protected the project and only development machines have the required compiler. What option will enable jobs with a parallel transformer to execute in the customers production machines?
A) Use protected projects in the production environment.
B) Add $APT_COMPILE_OPT=-portable
C) Set $APT_COPY_TRANSFORM_OPERATOR
D) Create a package with Information Server Manager and select the option to include executables.
5. Which job log message heading identifies the score in the job log?
A) main_program: This step has 3 datasets: ...
B) OSH script ...
C) main_program: Broadcasting score.
D) main_program: orchgeneral: loaded
