CLO-002 Exam Dumps - CompTIA Cloud Essentials Questions and Answers

Licensing models are the most likely financial consideration when selecting a cloud provider, as they determine how the cloud service is priced, billed, and consumed by the customer. Licensing models can vary depending on the type, level, and duration of the cloud service, as well as the vendor’s policies and agreements. Licensing models can have a significant impact on the total cost of ownership (TCO) and the return on investment (ROI) of the cloud service, as well as the customer’s flexibility, scalability, and security. Licensing models can also affect the customer’s compliance with legal and regulatory requirements, such as data protection, privacy, or intellectual property rights. Therefore, customers should carefully compare and evaluate different licensing models offered by different cloud providers, and choose the one that best suits their needs, budget, and goals12

Object storage is a cloud storage type that would be cost-effective and meet the requirements of a large online car retailer that needs to host photos that must be accessible from anywhere and available at anytime. Object storage is a type of cloud storage that stores data as objects, which consist of data, metadata, and a unique identifier. Object storage is ideal for storing large amounts of unstructured data, such as photos, videos, audio, documents, and web pages. Object storage offers several advantages for the online car retailer, such as:

• Cost-effectiveness: Object storage is typically cheaper than other types of cloud storage, such as file storage and block storage, because it does not require a complex file system or a high-performance storage network. Object storage also offers pay-per-use pricing, which means the retailer only pays for the amount of storage they consume.
• Accessibility: Object storage allows data to be accessed from anywhere and anytime, using a simple HTTP or HTTPS request. Object storage also supports RESTful APIs, which enable easy integration with web and mobile applications. Object storage can also leverage content delivery networks (CDNs), which distribute data across multiple locations to improve performance and availability.
• Scalability: Object storage can scale to store virtually unlimited amounts of data, without compromising performance or reliability. Object storage can also handle concurrent requests from multiple users, which is important for a high-traffic website like the online car retailer.
• Durability: Object storage ensures data durability by replicating data across multiple servers or regions, which protects data from hardware failures, natural disasters, or human errors. Object storage also supports versioning, which allows data to be restored to a previous state in case of accidental deletion or modification.

Self-service is one of the five essential characteristics of cloud computing, along with broad network access, resource pooling, rapid elasticity, and measured service1. Self-service enables cloud customers to provision and manage cloud resources without requiring human interaction from the cloud service provider2. Self-service allows cloud customers to have more control, flexibility, and agility over their cloud environment, and to perform various tasks such as building, decommissioning, scaling, monitoring, and configuring cloud resources according to their business needs and preferences3. Self-service is the best cloud characteristic to satisfy the business requirement of migrating mission-critical applications to the cloud, as it would enable technicians to perform routine functions more efficiently and effectively, and to respond to changing demands and situations more quickly and dynamically.

Broad network access is another essential characteristic of cloud computing, which means that cloud resources are available over the network and can be accessed by diverse customer platforms, such as laptops, mobile phones, tablets, etc1. Broad network access is an important feature of cloud computing, as it enables cloud customers to access their cloud resources anytime and anywhere, and to use different devices and methods to interact with the cloud. However, broad network access is not the best cloud characteristic to satisfy the business requirement of migrating mission-critical applications to the cloud, as it does not directly relate to the ability of technicians to build, decommission, and perform other routine functions on the cloud resources.

Elasticity is another essential characteristic of cloud computing, which means that cloud resources can be rapidly and dynamically scaled up or down according to the customer’s demand1. Elasticity is a key benefit of cloud computing, as it enables cloud customers to optimize the utilization and performance of their cloud resources, and to pay only for what they use. However, elasticity is not the best cloud characteristic to satisfy the business requirement of migrating mission-critical applications to the cloud, as it does not directly relate to the ability of technicians to build, decommission, and perform other routine functions on the cloud resources.

Availability is not one of the five essential characteristics of cloud computing, but rather a quality attribute or a non-functional requirement of cloud computing. Availability refers to the degree to which a system or service is operational and accessible when required4. Availability is a critical factor for cloud computing, especially for mission-critical applications, as it affects the reliability and continuity of the cloud service. However, availability is not the best cloud characteristic to satisfy the business requirement of migrating mission-critical applications to the cloud, as it does not directly relate to the ability of technicians to build, decommission, and perform other routine functions on the cloud resources. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 1: Cloud Computing Concepts, pages 11-15.

The most cost-effective solution for streaming is the one that offers the lowest cost per GB for storage and network. In this case, Provider 4 offers the lowest cost per GB for storage ($0.10) and network ($0.01). Additionally, Provider 4 offers the lowest cost for backup ($5.00) and VM cost ($4.00 per hour). References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 4: Selecting Cloud Service Providers, page 85

The first step for the business analyst to select a cloud provider for the new cloud project is to gather business and technical requirements for key stakeholders. Business requirements are the needs and expectations of the business units and end users, such as the goals, benefits, and outcomes of the project. Technical requirements are the specifications and constraints of the cloud solution, such as the performance, availability, security, and scalability. Gathering business and technical requirements is essential to understand the scope, objectives, and criteria of the project, and to evaluate and compare different cloud providers based on their capabilities and offerings1.

Conducting a feasibility study of the environment is a possible next step after gathering the requirements, to assess the viability and suitability of the cloud project, and to identify the risks, costs, and benefits of moving to the cloud2. Conducting a benchmark of all major systems is another possible step after gathering the requirements, to measure the current performance and utilization of the existing systems, and to determine the optimal configuration and resources for the cloud solution3. Drawing a matrix diagram of the capabilities of the cloud providers is a possible step after gathering the requirements and conducting the feasibility study and the benchmark, to compare and contrast the features and services of different cloud providers, and to select the best fit for the project4.

A communication policy is a set of guidelines that defines how an organization communicates with its internal and external stakeholders, such as employees, customers, partners, and regulators. A communication policy typically covers topics such as the purpose, scope, methods, frequency, tone, and responsibilities of communication within and outside the organization. A communication policy also establishes the standards and expectations for communication quality, accuracy, timeliness, and security. A communication policy is essential for ensuring effective, consistent, and transparent communication across the organization and with its stakeholders. A communication policy can help to avoid misunderstandings, conflicts, and errors that may arise from poor or unclear communication. A communication policy can also help to enhance the reputation, trust, and credibility of the organization.

A communication policy provides the best guidance about notifying users when a database is taken offline for planned maintenance, because it specifies how, when, and to whom such notifications should be sent. A communication policy can help to ensure that users are informed in advance, in a clear and courteous manner, about the reason, duration, and impact of the maintenance, and that they are updated on the progress and completion of the maintenance. A communication policy can also help to address any questions, concerns, or feedback that users may have regarding the maintenance. A communication policy can thus help to minimize the disruption and inconvenience caused by the maintenance, and to maintain a positive relationship with the users.

A communication policy is different from the other policies listed in the question, which are not directly related to notifying users about planned maintenance. An access control policy defines the rules and procedures for granting or denying access to information systems and resources based on the identity, role, and privileges of the users. An information security policy outlines the principles and practices for protecting the confidentiality, integrity, and availability of information assets and systems from unauthorized or malicious use, disclosure, modification, or destruction. A risk management policy describes the process and criteria for identifying, assessing, prioritizing, mitigating, and monitoring the risks that may affect the organization’s objectives, operations, and performance. While these policies are important for ensuring the security and reliability of the database and the organization, they do not provide specific guidance about communicating with users about planned maintenance.

Elasticity and pay-as-you-go are two main advantages of using ML/AI for data analytics in the cloud as opposed to on premises. Elasticity refers to the ability of cloud computing to dynamically adjust the amount of resources allocated to a workload according to the changing demand7. This allows ML/AI applications to access a large pool of compute resources when needed, such as GPUs or TPUs, without having to purchase or maintain them on premises8. Pay-as-you-go is a pricing model in which customers pay only for the resources they consume, such as compute, storage, network, or software services9. This allows ML/AI applications to save money by avoiding upfront costs or overprovisioning of resources on premises10.

The capital expenditure (CapEx) model is a financial model where an organization pays for the acquisition of physical assets upfront and then deducts that expense from its tax bill over time1. The CapEx model is typically used for on-premises infrastructure, where the organization has to purchase, install, and maintain servers, software licenses, and other hardware components. The CapEx model requires a large initial investment, but it also provides more control and ownership over the assets2.

The cloud, on the other hand, usually follows the operational expenditure (OpEx) model, where an organization pays for the consumption of cloud services on a regular basis, such as monthly or hourly. The OpEx model is also known as the pay-as-you-go model, and it allows the organization to scale up or down the cloud resources as needed, without having to incur any upfront costs or long-term commitments2. The OpEx model provides more flexibility and agility, but it also introduces more variability and uncertainty in the cloud expenditures3.

However, some cloud providers offer reservation models, where an organization can reserve cloud resources in advance for a fixed period of time, such as one or three years, and receive a discounted price compared to the pay-as-you-go rate. Reservation models can help an organization plan for cloud expenditures in a way that most closely aligns with the CapEx model, as they involve paying a lump sum upfront and then amortizing that cost over the reservation term4. Reservation models can also provide more predictability and stability in the cloud costs, as well as guarantee the availability and performance of the reserved resources5.

One example of a reservation model is the Amazon EC2 Reserved Instances (RI), which allow an organization to reserve EC2 instances for one or three years and save up to 75% compared to the on-demand price. Another example is the Azure Reserved Virtual Machine Instances (RIs), which allow an organization to reserve VMs for one or three years and save up to 72% compared to the pay-as-you-go price. Reservation models are also available for other cloud services, such as databases, containers, storage, and networking.

Therefore, using reserved cloud instances is the best strategy to plan for cloud expenditures in a way that most closely aligns with the CapEx model, as it involves paying a fixed amount upfront and receiving a discounted price for the reserved resources over a specified term. References: 1: https://www.browserstack.com/guide/capex-vs-opex  2: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, Chapter 6, page 215-216  3: https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/strategy/financial-considerations/  4: https://docs.aws.amazon.com/whitepapers/latest/cost-optimization-reservation-models/welcome.html  5: https://learn.microsoft.com/en-us/azure/well-architected/cost/design-price : https://aws.amazon.com/ec2/pricing/reserved-instances/ : https://azure.microsoft.com/en-us/pricing/reserved-vm-instances/ : https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, Chapter 5, page 179-180

Resource tagging is the best option for a client’s finance department to identify the cost of cloud use in a public cloud environment shared by different projects and departments. Resource tagging is a feature that allows users to assign metadata to their cloud resources. These tags, which consist of a key and a value, make it easier to manage, search for, and filter resources1. Resource tagging can help to manage costs effectively, especially in large-scale cloud environments, by enabling the following capabilities2:

• Cost allocation: Resource tagging can help to allocate costs to different projects, departments, or business units based on the tags that are associated with each resource. For example, a tag can indicate the owner, purpose, or environment of a resource, such as ProjectA, Marketing, or Dev. By using these tags, the finance department can generate reports that show the breakdown of cloud spending by different categories and attributes.
• Cost optimization: Resource tagging can help to optimize costs by identifying unused, underutilized, or overprovisioned resources based on the tags that are associated with each resource. For example, a tag can indicate the status, expiration date, or performance of a resource, such as Active, 2023-12-31, or High. By using these tags, the finance department can monitor and analyze the usage and efficiency of cloud resources and make recommendations for cost savings or improvements.
• Cost governance: Resource tagging can help to enforce cost governance policies and best practices by applying tags that are consistent, standardized, and mandatory across all cloud resources. For example, a tag can indicate the compliance, security, or quality of a resource, such as PCI-DSS, Confidential, or Approved. By using these tags, the finance department can audit and verify that the cloud resources are following the rules and regulations that are set by the organization or external authorities.

The other options are not as suitable as resource tagging for the client’s finance department to identify the cost of cloud use because:

• Reserved instances: Reserved instances are a pricing model that allows users to reserve cloud resources for a fixed period of time and pay a lower rate than on-demand resources. Reserved instances can help to reduce costs by offering discounts for predictable and steady usage patterns, but they do not provide a way to track and allocate costs across different projects and departments3.
• Service level agreement: A service level agreement (SLA) is a contract that defines the level of service and performance that a cloud service provider (CSP) guarantees to its customers. An SLA can help to ensure the reliability, availability, and quality of cloud services, but it does not provide a way to measure and report costs for different projects and departments.
• RFI from the CSP: An RFI (request for information) is a document that solicits information from a CSP about its products, services, and capabilities. An RFI can help to evaluate and compare different CSPs based on various criteria, such as features, benefits, and pricing, but it does not provide a way to monitor and manage costs for existing cloud resources that are used by different projects and departments.

 A network report is a document that provides information about the network usage and performance of a cloud service. It can help the company identify the network-related factors that may affect the responsiveness of the application, such as bandwidth, latency, jitter, packet loss, and throughput. A network report can also help the company monitor the network costs and optimize the network configuration to reduce the monthly bills.

A memory report, a compute report, and a storage report are documents that provide information about the memory, compute, and storage resources of a cloud service, respectively. They can help the company understand the resource consumption and performance of the application, but they are not the first documents to examine for the responsiveness issue. References: CompTIA Cloud Essentials+ CLO-002 Certification Study Guide, Chapter 4: Operating in the Cloud, Section 4.3: Monitoring Cloud Services, Page 133
