To answer this question, you need to understand the internal scripting language of the DataStage Engine.

Option A) Shell Script - This option is incorrect because Shell Script is not the internal scripting language of the DataStage Engine. Shell Script is a scripting language commonly used for automating tasks in Unix-based operating systems.

Option B) OSH - This option is correct. OSH (Orchestrate Shell) is the internal scripting language of the DataStage Engine. It is used to define and control the execution of DataStage jobs and perform various data integration tasks.

Option C) Scriptella - This option is incorrect. Scriptella is an open-source ETL (Extract, Transform, Load) and script execution framework, but it is not the internal scripting language of the DataStage Engine.

Option D) All the above - This option is incorrect because only option B (OSH) is the correct internal scripting language of the DataStage Engine.

The correct answer is B) OSH. This option is correct because OSH is the internal scripting language specifically designed for the DataStage Engine.

To answer this question, we need to understand what impersonation mode is and which operating systems support it.

Impersonation mode is a feature that allows a program or process to temporarily adopt the security credentials of another user or account. This can be useful in certain scenarios, such as when a program needs to access resources that are restricted to specific users or accounts.

Based on this understanding, let's go through each option:

Option A) UNIX - UNIX operating systems do support impersonation mode. Therefore, this option is incorrect.

Option B) LINUX - Linux operating systems also support impersonation mode. Therefore, this option is incorrect.

Option C) WINDOWS - Windows operating systems do not support impersonation mode. Therefore, this option is correct.

Option D) ALL THE ABOVE - Since Windows does not support impersonation mode, option D is incorrect.

The correct answer is C) WINDOWS. This option is correct because Windows operating systems do not support impersonation mode.

To answer this question, we need to understand the concept of node configuration in Datastage 8.5.

Datastage is an ETL (Extract, Transform, and Load) tool used for data integration and data transformation tasks. It enables users to design and execute workflows, known as jobs, that extract data from multiple sources, transform it according to business rules, and load it into target systems.

In Datastage, a node represents a physical or virtual server where Datastage components can be installed and executed. Nodes are used to distribute the workload of a job across multiple servers, improving performance and scalability.

The maximum number of nodes that can be configured in Datastage 8.5 is 8 (Option C). This means that you can install and configure Datastage components on up to 8 servers to distribute the workload of a job.

Option A (10) and Option B (6) are incorrect because they do not represent the maximum number of nodes that can be configured in Datastage 8.5.

Option D (infinity) is incorrect because there is a limit to the number of nodes that can be configured in Datastage 8.5, which is 8.

Therefore, the correct answer is C.
