CV0-003 Online Practice Questions and Answers

Correct Answer: D

Volume-based licensing is a pricing model that charges the customers based on the amount of usage or consumption of a software product or service. The more the customers use the software, the higher the costs will be. This model is suitable for applications that have variable or seasonal demand patterns. Examples of volume-based licensing are AWS Lambda, Azure Functions, Google Cloud Run, etc.

Correct Answer: C

A service account is a type of user account that is created for a specific service or application to run on a server or system. Creating a service account on the server is the best authentication technique to use within the playbook to run tasks against the server on a set schedule, as it can provide secure and consistent access to the server without exposing or hard-coding any sensitive credentials within the playbook. Creating a service account can also help manage and monitor the tasks and activities performed by the service or application on the server.

Correct Answer: C

Regression testing is a s/w testing practice that ensure an application still functions as expected after any code changes updates or improvements.

Usability testing is user-centric, getting input on how users use the application

Vulnerability testing evaluates security risks to reduce probability of getting hacked.

Correct Answer: C

Documenting the solution and placing it in a shared knowledge base is what the administrator should do next after troubleshooting performance issues with a VDI (Virtual Desktop Infrastructure) environment, determining that the issue is GPU (Graphics Processing Unit) related, increasing the frame buffer on the virtual machines, and testing that confirms that the issue is solved and everything is now working correctly. Documenting the solution is a process of recording and describing what was done to fix or resolve an issue, such as actions, steps, methods, etc., as well as why and how it worked. Placing it in a shared knowledge base is a process of storing and organizing documented solutions in a central location or repository that can be accessed and used by others. Documenting the solution and placing it in a shared knowledge base can provide benefits such as:

Learning: Documenting the solution and placing it in a shared knowledge base can help to learn from past experiences and improve skills and knowledge. Sharing: Documenting the solution and placing it in a shared knowledge base can help

to share information and insights with others who may face similar issues or situations.

Reusing: Documenting the solution and placing it in a shared knowledge base can help to reuse existing solutions for future issues or situations.

Correct Answer: C

The best way to restrict access to a set of sensitive files to a specific group of users is to change the file permissions and ownership of the files. File permissions and ownership are attributes that determine who can read, write, execute, or modify the files. By changing the file permissions and ownership, the systems administrator can grant or deny access to the files based on the user identity or group membership.

Correct Answer: A

Correct Answer: C

Explanation: Autoscaling is a feature that allows groups of compute units to horizontally scale according to a workload or predefined rules. Autoscaling can increase or decrease the number of compute units dynamically based on metrics such as CPU utilization, memory usage, network traffic, or user demand. Autoscaling can improve performance, availability, and cost-efficiency of cloud applications. References: [CompTIA Cloud+ Study Guide], page 75.

Correct Answer: A

A bucket Comprehensive Explanation: A bucket is a cloud storage solution that allows users to store and access objects, such as files, images, videos, etc. A bucket is typically associated with object storage services, such as Amazon S3,

Google Cloud Storage, or Microsoft Azure Blob Storage123. A bucket has the following characteristics that match the requirements of the application:

The owner of the objects is the object writer. This means that the user who uploads or writes an object to the bucket becomes the owner of that object and can control its access permissions456. The storage system enforces TLS encryption.

This means that the data in transit between the client and the bucket is encrypted using the Transport Layer Security (TLS) protocol, which provides security and privacy for the communication . A CIFS endpoint, a SAN, and an NFS mount

are not cloud storage solutions, but rather network protocols or architectures that enable access to storage devices
