Question 6 of 40

Consider a customer with multiple environments, Development, Test and Production. Which statement is TRUE?

Each environment must have a C++ compiler.

QualityStage rule sets are not a type of deployable asset.

It is not possible to revert to a previous version of a package.

A package can contain an improved version of a job which will replace the old one.

Correct Answer: D

A package can contain an improved version of a job which will replace the old one. This is useful for maintaining and updating software in multiple environments like Development, Test, and Production by allowing the deployment of new versions with enhanced features or fixes.

Question 7 of 40

Which of the following is TRUE when using a data set created with a 4 node config file?

Data sets are operating system files

Data is stored in a non-persistent form

The data set control file holds all your data

A Data Set stage can have 1 input link and multiple output links

Correct Answer: A

Data sets in a 4 node config file are generally operating system files. They are created and managed by the underlying operating system, making this the true statement out of the provided options.

Question 8 of 40

Which of the following is NOT TRUE about the DataStage job score?

It includes the operators automatically inserted at runtime

It helps to determine the number of actual operating system processes

It reports the amount of memory used by the inter-operator transport buffers

It outlines the connection topology between adjacent operators and persistent data sets

Correct Answer: C

The DataStage job score includes operators inserted at runtime, helps determine the number of operating system processes, and outlines the connection topology between adjacent operators and persistent data sets. However, it does not report the amount of memory used by the inter-operator transport buffers.

Question 9 of 40

Given this configuration file:

Which of the following describes the resulting behavior for a job consisting of Row Generator -> data set?

Conductor, section leader and player processes are executed on the server is1 and is2.

Conductor process is executed on the server is1. Section leader and Player processes are executed on the server is2.

Conductor and section leader processes are executed on the server is1. Player processes are executed on the server is2.

Conductor process and player processes are executed on the server is1. Section leader process is executed on the server is2.

Correct Answer: B

In a configuration file for parallel job execution, the conductor node is responsible for starting the job and managing its execution. The section leader process oversees the execution on each node, and player processes are the actual workhorses performing the job tasks. In the configuration provided, 'is1' serves as the conductor node, and 'is2' is another processing node. Therefore, the Conductor process gets executed on 'is1', while the section leader and player processes get executed on 'is2'. This aligns with option B, where the conductor process is on 'is1', and the section leader and player processes run on 'is2'.

Question 10 of 40

Given this score:

It runs 3 processes on 2 nodes.

How does the job run?

On two physical nodes and two logical nodes

On two physical nodes and single logical node

On a single physical node and two logical nodes

On a single physical node and single logical node

Correct Answer: B

The job runs on two physical nodes and a single logical node. This is indicated by the presence of two nodes, datastage.ibm.com.1 and datastage.ibm.com.2, but utilizing a single logical node structure for running the processes. The score indicates the parallel nature of tasks which are distributed across the specified physical nodes.
