CompTIA A+ Core 1 (220-1101) — Question 221

A cloud engineer, who is designing a cloud architecture, needs to ensure the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. Which of the following should the engineer implement? (Choose two.)

Answer options

• A. High availability
• B. Elasticity
• C. Cold storage
• D. Machine learning
• E. Metered utilization
• F. Virtualization

Correct answer: A, B

Explanation

High availability ensures that the system can switch to another region without downtime during an outage. Elasticity allows the system to automatically scale resources up or down based on demand, making it suitable for handling high utilization. The other options, such as Cold storage, Machine learning, Metered utilization, and Virtualization, do not directly address the requirements for immediate failover and scaling.
