What is the most efficient method for improving performance?

A company had only one server and later made an additional Qlik server available and configured it as a scheduler node. There is a recharge task that occurs every 30 minutes, every day. When the task is performed, users suffer from poor performance in browsing applications. Then, when analyzing the settings in QMC, the system administrator identifies that the consumption node runs the services: Engine, Scheduler, Repository, and Proxy. The scheduler node runs: Engine, Scheduler, and Repository.

What is the most efficient method for improving performance?
A . Increase the number of tasks on the scheduler node (Scheduler Node)
B. Remove the Scheduler service from the consumption node
C. Set tasks to run only during non-business hours, such as 00:00AM
D. Change the Scheduler Node to "Slave" (or Secondary) and the consumption node to "Master" (or
Primary)

Answer: D

Explanation:

Regarding the Scheduler service, until the September 2020 version the types were named as: Master

and Slave. As of the November 2020 version the types are named: Primary and Secondary.

Because there are two nodes with the Scheduler service running, it is ideal to direct the loads only to the schedules node and prevent the consumption node from doing so. That’s why it’s recommended to leave the Scheduler service of the scheduler node as Primary.

Primary (former Master): Sends the afternoon to the Secondary node (old slave);

Secondary (old Slave): Receives the task from the Primary node (old Master) and performs the task;

Primary and secondary: That’s when both act on reloading tasks.
