CompTIA CASP+ (CAS-004) — Question 146

An executive has decided to move a company's customer-facing application to the cloud after experiencing a lengthy power outage at a locally managed service provider's data center. The executive would like a solution that can be implemented as soon as possible. Which of the following will BEST prevent similar issues when the service is running in the cloud? (Choose two.)

Answer options

• A. Placing the application instances in different availability zones
• B. Restoring the snapshot and starting the new application instance from a different zone
• C. Enabling autoscaling based on application instance usage
• D. Having several application instances running in different VPCs
• E. Using the combination of block storage and multiple CDNs in each application instance
• F. Setting up application instances in multiple regions

Correct answer: A, F

Explanation

Placing application instances in different availability zones (A) ensures that if one zone experiences an issue, the application can continue running in another zone, enhancing reliability. Setting up instances in multiple regions (F) provides an additional layer of redundancy, protecting against regional outages. The other options do not provide the same level of resilience against outages.
