CompTIA Updated CV0-003 Exam Questions and Answers by killian

Shutting down the environment after work hours is the best process to automate to reduce cost, as it will stop incurring charges for the cloud resources that are not needed outside of work hours. Scaling, implementing access control, or blocking external access may still incur some costs for the cloud resources that are running or reserved, even if they are not fully utilized. Shutting down the environment can be automated using scripts, schedules, or triggers that can turn off or deallocate the cloud resources based on time or usage criteria12.

Containers are packages of software that contain all of the necessary elements to run in any environment. Containers virtualize the operating system and run anywhere, from a private data center to the public cloud or even on a developer’s personal laptop. Containers provide an isolated environment for running applications, sharing the host OS kernel but isolating processes, file systems, and network resources. Containers package applications and their dependencies together, ensuring they run consistently across different environments, from development to production. Containers are lightweight, resource-efficient, fast, and immutable, making them ideal for portability and scalability. By using containers, a cloud administrator can easily move resources from one environment to another without changing the code or configuration of the applications. References: CompTIA Cloud+ CV0-003 Study Guide, Chapter 2: Deploying a Cloud Environment, page 75-76; What are containers?; Portability in the Cloud: Cloud Native and Containers.

One possible answer is:

D. Migrate the data to flash storage.

Flash storage is a type of solid-state storage technology that uses flash memory chips to store data. Flash storage has several advantages over NL-SAS storage, which is a hybrid of SATA and SAS technologies that uses spinning disks to store data. Flash storage can provide much faster performance, lower latency, higher reliability, and lower power consumption than NL-SAS storage12. Therefore, migrating the data to flash storage can help correct the latency issue for the critical application. However, flash storage may also be more expensive and have lower capacity than NL-SAS storage, so these factors should also be considered before making the migration decision12.
