Exam SY0-701 topic 1 question 316 discussion

The correct answer is: D. Production failover Explanation: Production failover tests the resiliency of systems in the event of a primary power failure by switching operations from the primary system to a backup or secondary system in a live environment. It ensures that the failover process works as intended and that systems remain operational during an actual outage. Other Options: A. Parallel processing: Refers to splitting tasks across multiple systems for efficiency and does not test resiliency in case of a power failure. B. Tabletop exercise: A discussion-based exercise to simulate scenarios but does not involve actual testing of systems. C. Simulation testing: Tests a simulated environment but may not reflect real-world conditions as accurately as a production failover. Production failover is the best way to test resiliency because it verifies that systems can handle a power failure in a real, operational environment.

I believe answer is Parallel processing. Parallel, meaning contingency, when it comes to improved recovery of a faulty system and continuity of operations.

Explanation: Production failover is the process of switching from the primary system (which could be affected by a power failure or other disruption) to a secondary, backup system that is designed to take over in the event of an outage. This is the most effective way to test resiliency because it simulates the actual failure scenario in a real-world environment and ensures that the backup system operates as expected. NOT C. Simulation testing: Simulation testing involves recreating a specific scenario to test the system’s response. While helpful for certain types of tests, it may not provide the same level of realism as a production failover test where the systems actually switch over to backups during a real or simulated failure.

Production failover is the most effective way to test resiliency in the event of a primary power failure. It involves simulating a power outage and switching to a backup power source or a redundant system. This allows organizations to assess the effectiveness of their backup systems and recovery procedures in a real-world scenario.

Answer is C

Chat GPT: The correct answer is D. Production failover. A production failover is the best way to test resiliency in the event of a primary power failure because it involves switching from the primary system to a backup system in a real-world environment. This tests the actual failover processes and infrastructure under real conditions, ensuring that systems can continue to operate if the primary power source fails. A. Parallel processing is related to computing performance and efficiency, not specifically to power resiliency. B. Tabletop exercise is a discussion-based exercise to simulate scenarios, but it doesn’t provide practical validation of systems under actual failover conditions. C. Simulation testing is a hypothetical or virtual test that can assess various failure scenarios, but it doesn't fully replicate the impact of a real production failover.

D. Production failover Production failover involves switching to a backup power source or system to ensure that operations continue seamlessly in the event of a primary power failure. This type of testing verifies that the failover mechanisms work as intended under real-world conditions and ensures that the system can handle the transition smoothly.
