Which of the following is the PRIMARY advantage of parallel processing for a new system implementation?
The primary advantage of parallel processing for a new system implementation is the assurance that the new system meets performance requirements. By running the new system alongside the existing one, comparisons can be made regarding their performance. This side-by-side operation allows for the identification and resolution of any performance issues before the new system is fully transitioned into use, ensuring a smooth and disruption-free switchover.
A: If functional requirements are not met the system will continue to run on parallel mode until they are address. Performance is important but functional requirements take precedence
By running the old and new systems concurrently during a parallel implementation, you can compare their performance metrics. This allows you to identify bottlenecks or scalability issues in the new system before fully transitioning users. This aligns with best practices for system implementation, where performance testing is crucial for a smooth transition. Therefore, based on the focus on performance testing during system implementations, answer choice D is the most likely primary advantage according to general IT best practices, which align with CISA's focus on secure and reliable systems.
Parallel processing involves running the new system alongside the existing system during a transition period, allowing for a side-by-side comparison of performance. This approach helps to identify any performance issues in the new system before it is fully implemented, ensuring that it meets the performance requirements specified for the system. This can also help to minimize any potential downtime or disruptions that could occur during a full switchover to the new system.
CISA Study Guide 27th: The purpose of parallel testing is to ensure that the implementation of a new system will meet user requirements.
D is the right Answer
Functional is the correct answer
user requirements hence functional requirements.
is the correct answer , the functional requirement first then Performance
Assurance that the new system meets functional requirements
A, refer to CRM not your own intuition
Parallel testing—The process of feeding test data into two systems—the modified system and an alternative system (possibly the original system)— and comparing the results. The purpose of parallel testing is to determine whether the new application performs in the same way as the original system and meets end-user requirements.
hile assurance that the new system meets functional requirements (option A) is important, the PRIMARY advantage of parallel processing is its ability to validate and assure performance requirements, making option D the most appropriate choice.
Answer: D
If the new system is not functional then could fall back to the old system
