CompTIA Cloud+ CV0-003 Practice Question
A company is deploying a web application in the cloud and expects variable traffic, with occasional spikes during certain events. To ensure the application remains responsive without incurring unnecessary costs during off-peak times, the cloud engineer has been asked to configure an auto-scaling service. What is the most effective scaling policy the engineer should implement to meet these requirements?
Manual scaling policy, requiring an administrator to manually increase or decrease the number of instances as needed.
Schedule-based scaling policy, adding instances in anticipation of high traffic events known in advance.
Target tracking scaling policy, configuring it to maintain a specific target for average CPU utilization.
Maintain a fixed number of instances at all times, regardless of traffic patterns.
