CompTIA CLO-002 Online Questions & Answers

• Question 111:

  A small online retailer is looking for a solution to handle the high load on its servers during the holiday season. The retailer is not currently ready to move its IT operations completely to the cloud.

  Which of the following will BEST fit these requirements?

  A. Elasticity
  B. Scalability
  C. Bursting
  D. Self-service
  C. Bursting

  ---

  Explanation/Reference:

  Cloud bursting is a configuration method that uses cloud computing resources whenever on-premises infrastructure reaches peak capacity. When organizations run out of computing resources in their internal data center, they burst the extra workload to external third-party cloud services. Cloud bursting is a convenient and cost-effective way to to support workloads with varying demand patterns and seasonal spikes in demand12. Elasticity and scalability are related concepts, but they are not specific solutions for the retailer's problem. Elasticity refers to the ability of a cloud service to automatically adjust the amount of resources allocated to a workload based on the current demand3. Scalability refers to the ability of a cloud service to handle increasing or decreasing workloads by adding or removing resources4. Self-service is a feature of cloud computing that allows users to provision, manage, and monitor their own cloud resources without the need for human intervention5. While these features are beneficial for cloud consumers, they do not address the retailer's need to handle the high load on its servers during the holiday season without moving its IT operations completely to the cloud.

• Question 112:

  Which of the following can be set up to inform the consumer of rising performance thresholds?

  A. Alerts
  B. Audit
  C. Logging
  D. Scanning
  D. Scanning

  Explanation/Reference:

  According to the CompTIA Cloud Essentials objectives and documents, sandboxing is the best option for the DevOps team that wants to document the upgrade steps for its public database solution. Sandboxing is a technique that creates a virtual environment that is isolated from the production systems and allows the team to replicate multiple installations without affecting the real data or applications. Sandboxing is useful for testing, debugging, and experimenting with new features or configurations in a safe and controlled way. Sandboxing can also help the team to identify and resolve any potential issues or errors before deploying the upgrade to the production environment. The other options are not as suitable for the team's needs. Containerization is a method of packaging software code with the necessary dependencies and libraries to run it on any platform or cloud. Containerization is beneficial for creating portable and scalable applications that can run consistently across different environments. However, containerization does not provide a dedicated virtual environment that is separate from the production systems, nor does it allow the team to replicate multiple installations of the same software. Cold storage is a type of data storage that is used for infrequently accessed or archived data. Cold storage is typically cheaper and slower than hot storage, which is used for frequently accessed or active data. Cold storage is not relevant for the team's need to document the upgrade steps for its public database solution, as it does not involve data storage or access. Infrastructure as code is a practice of managing and provisioning cloud infrastructure using code or scripts, rather than manual processes or graphical user interfaces. Infrastructure as code is advantageous for automating and standardizing the deployment and configuration of cloud resources, such as servers, networks, or storage. However, infrastructure as code does not provide a dedicated virtual environment that is separate from the production systems, nor does it allow the team to replicate multiple installations of the same software.

• Question 113:

  Which of the following can be used by a client's finance department to identify the cost of cloud use in a public cloud environment shared by different projects and departments?

  A. Reserved instances
  B. Service level agreement
  C. Resource tagging
  D. RFI from the CSP
  C. Resource tagging

  ---

  Explanation/Reference:

  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.

• Question 114:

  A project manager must inform the Chief Information Officer (CIO) of the additional resources necessary to migrate services to the cloud successfully.

  Which of the following cloud assessments would be MOST appropriate to use for the recommendation?

  A. Feasibility study
  B. Gap analysis
  C. Future requirements
  D. Baseline report
  B. Gap analysis

  ---

  Explanation/Reference:

  A gap analysis is a process of comparing the current state and the desired state of a system or a process and identifying the gaps or differences between them. A gap analysis can help an organization to determine the steps and resources needed to achieve its goals and objectives. A gap analysis can be used for cloud migration to assess the readiness and suitability of the existing services and applications for the cloud, and to identify the gaps in terms of performance, security, functionality, compatibility, and cost. A gap analysis can also help to prioritize the migration tasks and to estimate the time and effort required for the migration1. The other options are not appropriate for the recommendation: Feasibility study: This is a process of evaluating the viability and benefits of a proposed project or solution. A feasibility study can help an organization to determine whether a project is worth pursuing, and to identify the potential risks and challenges involved. A feasibility study can be used for cloud migration to evaluate the benefits and drawbacks of moving to the cloud, and to compare different cloud service models and providers. A feasibility study can also help to define the scope and objectives of the migration project2. However, a feasibility study is not sufficient to inform the CIO of the additional resources necessary for the migration, as it does not provide a detailed analysis of the gaps and requirements of the existing services and applications. Future requirements: These are the needs and expectations of the organization and its stakeholders for the future state of the system or the process. Future requirements can help an organization to plan and design the system or the process to meet the changing demands and opportunities. Future requirements can be used for cloud migration to envision the desired outcomes and benefits of moving to the cloud, and to align the migration strategy with the business strategy and goals3. However, future requirements are not specific enough to inform the CIO of the additional resources necessary for the migration, as they do not provide a detailed analysis of the gaps and requirements of the existing services and applications. Baseline report: This is a document that records the current state and performance of the system or the process, and serves as a reference point for measuring the progress and improvement. A baseline report can help an organization to monitor and evaluate the system or the process, and to identify the areas of strength and weakness. A baseline report can be used for cloud migration to measure the performance and functionality of the existing services and applications, and to compare them with the cloud-based services and applications4. However, a baseline report is not comprehensive enough to inform the CIO of the additional resources necessary for the migration, as it does not provide a detailed analysis of the gaps and requirements of the existing services and applications.

• Question 115:

  When selecting a cloud provider, which of the following is MOST likely to be a financial consideration?

  A. Proof of concept
  B. Request for information
  C. Licensing models
  D. Request for proposal
  C. Licensing models

  ---

  Explanation/Reference:

  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 References: CompTIA Cloud Essentials+ Certification Exam Objectives3, CompTIA Cloud Essentials+ Study Guide, Chapter 2: Business Principles of Cloud Environments

• Question 116:

  Which of the following strategies allows an organization to plan for cloud expenditures in a way that most closely aligns with the capital expenditure model?

  A. Simplifying contract requirements
  B. Implementing consolidated billing
  C. Considering a BYOL policy
  D. Using reserved cloud instances
  D. Using reserved cloud instances

  ---

  Explanation/Reference:

  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:

• Question 117:

  A company is evaluating the capital expenditure necessary to modernize its on-premises datacenter. Management has directed that 50% of capital expenditure be reallocated to operating expenditure. Which of the following cloud characteristics applies?

  A. BYOL
  B. Billing chargeback
  C. Pay-as-you-go
  D. High availability
  C. Pay-as-you-go

  ---

  Explanation/Reference:

  Pay-as-you-go is a cloud characteristic that applies to the scenario of reallocating capital expenditure to operating expenditure. Pay-as-you-go is a billing model in which customers only pay for the cloud resources and services they consume, without any upfront or fixed costs1. Pay-as-you-go allows customers to shift from CapEx to OpEx, as they do not need to invest in physical infrastructure or long-term contracts, but rather pay for what they use as they use it2. Pay-as-you-go also provides flexibility and scalability, as customers can adjust their usage and spending according to their needs and demand3. BYOL stands for Bring Your Own License, which is a cloud characteristic that allows customers to use their existing software licenses on the cloud provider's platform, instead of purchasing new licenses from the cloud provider4. BYOL can help customers save money and avoid vendor lock-in, but it does not necessarily affect the allocation of CapEx and OpEx. Billing chargeback is a cloud characteristic that enables customers to allocate and track the costs of cloud resources and services to different departments, projects, or business units within their organization5. Billing chargeback can help customers optimize their cloud spending and improve accountability and transparency, but it does not directly influence the balance of CapEx and OpEx. High availability is a cloud characteristic that refers to the ability of a cloud system to remain operational and accessible at all times, even in the event of failures or disruptions. High availability is achieved by using redundant and fault-tolerant components, such as servers, networks, and storage, that can automatically failover or switch to backup resources in case of an outage. High availability is an important benefit of cloud computing, as it ensures reliability and performance, but it does not relate to the distinction between CapEx and OpEx. References:

• Question 118:

  Which of the following activities in a cloud environment requires a defined scope and formal authorization from the CSP?

  A. Orchestration
  B. Penetration testing
  C. Sandboxing
  D. Vulnerability scanning
  B. Penetration testing

  ---

  Explanation/Reference:

  Penetration testing, also known as ethical hacking, is a security assessment methodology that involves simulating a cyberattack on a cloud-based system or service to identify and exploit vulnerabilities and weaknesses.

  Penetration testing can help to evaluate the security posture of a cloud environment and provide recommendations for improvement12

  Penetration testing in a cloud environment requires a defined scope and formal authorization from the cloud service provider (CSP), because it can have significant impacts on the cloud infrastructure, applications, and data. Penetration

  testing can potentially cause damage, disruption, or breach of the cloud resources, as well as violate the terms of service or the service level agreements of the CSP. Therefore, before conducting penetration testing in a cloud environment,

  the customer must obtain the consent and approval of the CSP, and follow the guidelines and policies of the CSP regarding the scope, duration, frequency, and methods of the testing3 Orchestration, sandboxing, and vulnerability scanning

  are not activities that require a defined scope and formal authorization from the CSP, because they are less intrusive and disruptive than penetration testing. Orchestration is the process of automating and coordinating the deployment and

  management of cloud resources using tools and scripts. Sandboxing is the process of creating and isolating a testing environment within the cloud to experiment with new features or applications without affecting the production environment.

  Vulnerability scanning is the process of detecting and reporting the known vulnerabilities and misconfigurations in the cloud resources using automated tools. These activities can help to improve the efficiency, flexibility, and security of the

  cloud environment, but they do not involve actively exploiting or compromising the cloud resources. Therefore, they do not require the same level of permission and oversight from the CSP as penetration testing.

• Question 119:

  A company's finance team is reporting increased cloud costs against the allocated cloud budget. Which of the following is the BEST approach to match some of the cloud operating costs with the appropriate departments?

  A. Right-sizing
  B. Scaling
  C. Chargeback
  D. Showback
  C. Chargeback

  ---

  Explanation/Reference:

  Chargeback is the best approach to match some of the cloud operating costs with the appropriate departments. Chargeback is a process where the IT department bills each department for the amount of cloud resources they use, such as compute, storage, network, or software. Chargeback can help the company to allocate the cloud costs more accurately and fairly, as well as to encourage the departments to optimize their cloud consumption and reduce waste. Chargeback can also provide the company with more visibility and accountability of the cloud usage and spending across the organization12 Chargeback is different from showback, which is a process where the IT department shows each department the amount of cloud resources they use, but does not charge them for it. Showback can also help the company to increase the awareness and transparency of the cloud costs, but it may not have the same impact on the behavior and efficiency of the departments as chargeback12 Right-sizing and scaling are not approaches to match the cloud costs with the departments, but rather techniques to adjust the cloud resources to the actual demand and performance of the applications or services. Right-sizing and scaling can help the company to save money and improve the cloud utilization, but they do not address the issue of cost allocation or attribution34 References: CompTIA Cloud Essentials+ Certification Exam Objectives, CompTIA Cloud Essentials+ Study Guide, Chapter 2: Business Principles of Cloud Environments, IT Chargeback vs Showback: What's The Difference?2, Cloud Essentials+ Certification Training

• Question 120:

  Which of the following BEST describes how a cloud provider helps a company with security risk responses?

  A. Acceptance
  B. Mitigation
  C. Avoidance
  D. Transference
  D. Transference

  ---

  Explanation/Reference:

  Transference is the best description of how a cloud provider helps a company with security risk responses. Transference means shifting the responsibility or liability for the risk to another party, such as an insurance company or a cloud service provider (CSP). By using a CSP, the company can transfer some of the security risks to the provider, who has more expertise and resources to manage them. However, the company still retains the ownership and accountability for the data and applications hosted in the cloud, and must ensure that the CSP meets the agreed-upon service level agreements (SLAs) and security standards. The company cannot transfer all the security risks to the CSP, as some risks are inherent to the cloud environment, such as data breaches, misconfigurations, or compliance violations12.
