Implementing DevOps Solutions and Practices Using Cisco Platforms (DEVOPS) — Question 23

What is the effective way to manage computing costs in a public cloud?

Answer options

• A. Monitor data transfers to minimize cost.
• B. Use dedicated hardware for all instances.
• C. Select the largest instance option available in order to pay for only one instance.
• D. Make use of elastic services and scale on demand.

Correct answer: D

Explanation

The correct answer, D, highlights the advantage of using elastic services that allow resources to be scaled up or down based on demand, effectively managing costs. Option A, while beneficial, focuses only on data transfer without addressing overall resource management. Option B suggests an inefficient approach by locking into dedicated hardware, which can lead to unnecessary expenses. Option C is misleading as it implies that larger instances are more cost-effective, which is not necessarily true for varied workloads.
