CV0-004 Free Practice Test

A cloud server needs to automatically allocate more resources during sudden peak times. This allocation does not need to occur in regular intervals. Which of the following scaling
approaches should be used?

1. A. Event
2. B. Manual
3. C. Trending
4. D. Scheduled

Correct Answer: A
Event-based scaling is designed to allocate more resources automatically in response to specific events, such as sudden peak times that are not regular or predictable. This type of scaling ensures that resources are available when needed without the need to schedule them in advance or adjust them manually.

A cloud administrator needs to distribute workloads across remote data centers for redundancy reasons. Which of the following deployment strategies would eliminate downtime, accelerate deployment, and remain cost efficient?

1. A. In-place
2. B. Rolling
3. C. Blue-green
4. D. Canary

Correct Answer: C
Blue-green deployment is the strategy that can eliminate downtime, accelerate deployment, and remain cost-efficient. It involves running two identical production environments, only one of which is live at any given time (blue or green). When it's time to deploy, the new version is released to the inactive environment (green), which is then thoroughly tested. Once ready, the traffic is switched over, making the green environment live.References: Deployment strategies and their impact on operations are a significant topic within the CompTIA Cloud+ examination objectives.
