CompTIA Cloud+ Practice Test

To confirm high availability claimed by a cloud service, which techniques should be applied?

1. Vulnerability testing

2. Penetration testing

3. Load testing

4. Failover testing

The correct answer is: Penetration testing

In the context of confirming high availability in a cloud service, failover testing is the most relevant technique. High availability emphasizes the continuous operation of services, even in the event of failures. Failover testing specifically assesses the system's ability to switch operations to a backup system or component when an outage or failure occurs, ensuring minimal disruption to the cloud services provided. By performing failover testing, organizations can simulate various failure scenarios to validate that the cloud service can consistently maintain service levels through redundancy and backup resources. This process helps identify any weaknesses in the system's architecture that could lead to downtime and ensures that recovery mechanisms function as intended. Thus, failover testing is critical for confirming that high availability claims made by a cloud service are legitimate and reliable. Vulnerability testing and penetration testing focus more on security aspects rather than availability. Load testing, while important for performance evaluation, does not directly address the system's ability to recover from failures or maintain uptime in adverse conditions.
