CompTIA CLO-002 Exam Dumps Questions and Answers

Resource tagging is a method of assigning metadata to cloud resources, such as instances, volumes, buckets, databases, etc. Resource tagging can help identify, organize, and manage cloud resources based on various criteria, such as name, purpose, owner, environment, or cost center1. Resource tagging can also help track and report the costs of cloud resources, as the cloud service provider can generate billing and cost management reports based on the tags applied to the resources2. Resource tagging is the best option for the business analysis team to report on the costs of the specific cloud application, as it would enable them to separate and filter the costs by the application tag.

Right-sizing is a technique of adjusting the size and type of cloud resources to match the actual needs and usage patterns of an application3. Right-sizing can help optimize the performance and cost of cloud resources, but it does not directly help report on the costs of the specific cloud application, as it does not provide a way to separate and filter the costs by the application.

Content management is a process of creating, storing, organizing, and delivering digital content, such as documents, images, videos, etc. Content management can help manage the lifecycle and accessibility of digital content, but it does not directly help report on the costs of the specific cloud application, as it does not provide a way to separate and filter the costs by the application.

Optimization is a process of improving the efficiency and effectiveness of cloud resources, such as by reducing waste, increasing performance, or enhancing security4. Optimization can help improve the quality and value of cloud resources, but it does not directly help report on the costs of the specific cloud application, as it does not provide a way to separate and filter the costs by the application. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 5: Cloud Resource Management, pages 187-188.

A software-defined network (SDN) is a category of technologies that make it possible to manage a network via software. SDN technology enables IT administrators to configure their networks using a software application. SDN software is interoperable, meaning it should be able to work with any router or switch, no matter which vendor made it1. SDN is used to build and manage interconnections between cloud resources within the same cloud environment, as it allows for greater flexibility, scalability, and automation of network configuration and operation2. SDN is also a key component of cloud computing, as it enables the creation of virtual networks that can span across different physical infrastructures3.

A firewall is a device or software that monitors and controls incoming and outgoing network traffic based on predefined rules. A firewall is used to protect a network from unauthorized access or malicious attacks, but it does not create or manage interconnections between cloud resources4.

A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a public network, such as the Internet. A VPN is used to extend a private network across a public network, allowing users to access remote resources as if they were on the same local network. A VPN is not used to build or manage interconnections between cloud resources within the same cloud environment, but rather to connect different cloud environments or users to a cloud environment5.

Direct Connect is a service offered by some cloud providers, such as Amazon Web Services (AWS), that allows customers to establish a dedicated network connection between their premises and the cloud provider’s data center. Direct Connect is used to bypass the public Internet and provide a more consistent and secure network performance, as well as lower costs and latency. Direct Connect is not used to build or manage interconnections between cloud resources within the same cloud environment, but rather to connect a customer’s network to a cloud provider’s network. References: What is software-defined networking (SDN)? | Cloudflare, What is Software-Defined Networking? - IBM, Software-defined networking - Wikipedia, What is a firewall? | Cloudflare, What is a VPN? | Cloudflare, [AWS Direct Connect - Amazon Web Services]

RTO stands for Recovery Time Objective, which is a metric that measures the maximum acceptable amount of time that an application or a service can be offline or unavailable after a disruption, such as a server failure, a power outage, or a natural disaster. RTO is a key indicator of the disaster recovery capabilities and objectives of an organization, as it reflects the level of tolerance or impact of downtime on the business operations, reputation, and revenue. RTO is usually expressed in hours, minutes, or seconds, and it can vary depending on the criticality and priority of the application or the service. RTO can help an organization to determine the optimal level of backup, redundancy, and recovery for the application or the service, as well as the potential costs and risks of downtime. RTO can also help the organization to choose the appropriate cloud service model, provider, and deployment option that can meet the disaster recovery requirements and expectations of the organization and its customers12

Therefore, the best explanation of the concept of RTOs for restoring servers to operational use is to reduce the amount of time a particular server is unavailable and offline, as this implies the goal of minimizing the duration and frequency of downtime, and restoring the normal operations and functionality of the server as quickly as possible.
