Test your knowledge of IT Resilience and Redundancy

Question 1

Your organization owns a critical e-commerce web application, and you need to ensure that the application remains available in case of a natural disaster. Which of the following redundancy solutions would be the most suitable?

Correct Answer: Establish a geographically separate redundant data center

A geographically separate redundant data center ensures that the web application continues to operate in the event of a natural disaster affecting the primary data center. Other options may help increase resilience, but they do not provide adequate protection against natural disasters.

Question 2

A large organization relies on a legacy server that runs critical software. However, the server is reaching its end of life and may not be able to handle an increasing workload. What would be the best solution to ensure resilience and redundancy?

Correct Answer: Migrate the legacy software to a cluster of new servers

Migrating to a cluster of new servers ensures improved resilience and redundancy. This arrangement can carry the increased workload and provide failover capabilities. Other options may help, but they do not sufficiently address the problem of the aging hardware and increased workload.

Question 3

Your company handles sensitive customer data and must ensure strong security measures in place. Unfortunately, a major power outage occurs at your data center, compromising these security measures. What redundancy solution should have been implemented to prevent this?

Correct Answer: Deploy an uninterruptible power supply (UPS) and backup diesel generators

Deploying an uninterruptible power supply (UPS) and backup diesel generators would provide continued power during an outage, ensuring security measures remain operational. Other options do not directly address the power outage issue.
