CompTIA CompTIA Certifications CLO-002 Questions & Answers

• Question 141:

  An organization plans to keep three of its cloud servers online for another nine months and a fourth server online for a year. The current pricing is $200 per month per server. The cloud provider announced the sale price of $1,500 per year per reserved instance.

  Which of the following represents the cost savings by converting all four of the cloud servers to reserved instances?

  A. $900

  B. $1,800

  C. $2,400

  D. $3,600

  Correct Answer: B

  Explanation: The cost savings by converting all four of the cloud servers to reserved instances can be calculated as follows:

  The current pricing is $200 per month per server, which means the total cost for keeping three servers online for another nine months is $200 x 3 x 9 = $5,400, and the total cost for keeping one server online for a year is $200 x 1 x 12 =

  $2,400. The total cost for all four servers is $5,400 + $2,400 = $7,800. The sale price of $1,500 per year per reserved instance means the total cost for converting all four servers to reserved instances is $1,500 x 4 = $6,000. The cost savings

  by converting all four servers to reserved instances is $7,800 - $6,000 = $1,800.

• Question 144:

  A small business wants to move its accounting operations to the cloud. Which of the following cloud service models would put the MOST liability on the provider with regard to shared responsibility?

  A. laaS

  B. BPaaS

  C. PaaS

  D. SaaS

  Correct Answer: D

  Explanation: SaaS stands for Software as a Service, which is a cloud service model that provides ready-to-use software applications over the internet. The cloud service provider (CSP) is responsible for managing and maintaining the software, including its development, deployment, updates, security, availability, and performance. The customer only needs to access the software through a web browser or a client application, and pay for the usage or subscription. SaaS puts the most liability on the provider with regard to shared responsibility, as the provider handles most of the security and operational tasks for the software, and the customer has minimal control and customization options. Examples of SaaS applications include email, CRM, ERP, accounting, and collaboration tools. The other cloud service models put less liability on the provider and more on the customer, as the customer has more control and responsibility over the cloud resources. IaaS stands for Infrastructure as a Service, which provides virtualized computing resources such as servers, storage, and networking over the internet. The CSP is responsible for securing and maintaining the physical infrastructure, while the customer is responsible for managing the operating system, applications, data, and configurations. PaaS stands for Platform as a Service, which provides a cloud-based environment for developing, testing, and deploying software applications. The CSP is responsible for managing the underlying infrastructure, middleware, and runtime environment, while the customer is responsible for developing, deploying, and managing the applications and data. BPaaS stands for Business Process as a Service, which provides a cloud-based platform for automating and orchestrating business processes. The CSP is responsible for managing the platform, including its integration, security, and scalability, while the customer is responsible for defining, executing, and monitoring the business processes and rules. Therefore, the correct answer is D. SaaS, as it puts the most liability on the provider with regard to shared responsibility.

• Question 145:

  Which of the following is the cloud storage technology that would allow a company with 12 nearly identical servers to have the SMALLEST storage footprint?

  A. Capacity on demand

  B. Compression

  C. Software-defined storage

  D. Deduplication

  Correct Answer: D

  Explanation: Deduplication is the cloud storage technology that would allow a company with 12 nearly identical servers to have the smallest storage footprint. Deduplication is the process of eliminating redundant or duplicate data blocks within a storage system, and replacing them with pointers to a single copy of the data. Deduplication can reduce the amount of storage space required, as well as the bandwidth and cost of data transfer. Deduplication is especially effective for data that has a high degree of similarity, such as backup data, virtual machine images, or server data. Deduplication can be performed at the source or the target, and at the file or the block level.

• Question 146:

  An organization determines it cannot go forward with a cloud migration due to the risks involved. Which of the following types of risk response does this describe?

  A. Acceptance

  B. Transference

  C. Avoidance

  D. Mitigation

  Correct Answer: C

  Explanation: According to the CompTIA Cloud Essentials+ Study Guide, risk response is the process of developing and implementing strategies to address the identified risks in a cloud project1. There are four types of risk response strategies: acceptance, transference, avoidance, and mitigation1. Each strategy has its own advantages and disadvantages, depending on the nature and impact of the risk. Acceptance is the strategy of acknowledging the risk and its consequences, without taking any action to reduce or eliminate it. This strategy is suitable for risks that have low probability and low impact, or for risks that are unavoidable or too costly to address. Acceptance can be passive, where no contingency plans are prepared, or active, where some reserves or fallback options are allocated1. Transference is the strategy of shifting the risk and its responsibility to a third party, such as a cloud service provider, an insurance company, or a subcontractor. This strategy is suitable for risks that have high impact but low probability, or for risks that require specialized skills or resources to handle. Transference does not eliminate the risk, but it reduces the exposure and liability of the organization. However, transference also involves some costs and trade-offs, such as loss of control, dependency, or contractual issues1. Avoidance is the strategy of eliminating the risk and its causes, by changing the scope, plan, or design of the cloud project. This strategy is suitable for risks that have high probability and high impact, or for risks that are unacceptable or intolerable for the organization. Avoidance can be effective in removing the threat, but it can also result in missed opportunities, reduced benefits, or increased costs1. Mitigation is the strategy of reducing the probability and/or impact of the risk, by implementing some preventive or corrective actions. This strategy is suitable for risks that have moderate probability and impact, or for risks that can be controlled or minimized. Mitigation can be proactive, where actions are taken before the risk occurs, or reactive, where actions are taken after the risk occurs1. In the given scenario, an organization determines it cannot go forward with a cloud migration due to the risks involved. This describes the avoidance strategy, as the organization is eliminating the risk and its causes by changing the plan of the cloud project. The organization is avoiding the potential negative consequences of the cloud migration, but it is also foregoing the potential benefits and opportunities of the cloud adoption.

• Question 147:

  Which of the following would BEST provide access to a Windows VDI?

  A. RDP

  B. VPN

  C. SSH

  D. HTTPS

  Correct Answer: A

  Explanation: RDP stands for Remote Desktop Protocol, which is a protocol that allows a user to remotely access and control a Windows-based computer or virtual desktop from another device over a network. RDP can be used to provide access to a Windows VDI, which is a virtual desktop infrastructure that delivers Windows desktops and applications as a cloud service. RDP can provide a full graphical user interface, keyboard, mouse, and audio support, as well as features such as clipboard sharing, printer redirection, and file transfer. RDP can be accessed by using the built-in Remote Desktop Connection client in Windows, or by using third-party applications or web browsers. RDP is more suitable for accessing a Windows VDI than other protocols, such as VPN, SSH, or HTTPS, which may not support the same level of functionality, performance, or security.

• Question 148:

  A redundancy option must be provided for an on-premises server cluster. The financial team is concerned about the cost of extending to the cloud. Which of the following resources about the on-premises infrastructure would BEST help to estimate cloud costs?

  A. Server cluster architecture diagram

  B. Compute and storage reporting

  C. Industry benchmarks

  D. Resource management policy

  Correct Answer: B

  Explanation: Compute and storage reporting is the best resource to help estimate cloud costs for a redundancy option for an on-premises server cluster. Compute and storage reporting provides information about the current usage and performance of the on- premises servers, such as CPU, memory, disk, network, and I/O metrics. This information can help to determine the appropriate cloud service level and configuration that can match or exceed the on-premises capabilities. Compute and storage reporting can also help to identify any underutilized or overprovisioned resources that can be optimized to reduce costs12 Server cluster architecture diagram is not the best resource to help estimate cloud costs, because it only shows the logical and physical structure of the on-premises server cluster, such as the number, type, and location of the servers, and the connections and dependencies between them. This information can help to understand the high-level design and requirements of the server cluster, but it does not provide enough details about the actual usage and performance of the servers, which are more relevant for cloud cost estimation3 Industry benchmarks are not the best resource to help estimate cloud costs, because they only show the average or standard performance and cost of similar server clusters in the same industry or domain. Industry benchmarks can help to compare and evaluate the on- premises server cluster against the best practices and expectations of the market, but they do not reflect the specific needs and characteristics of the server cluster, which are more important for cloud cost estimation4 Resource management policy is not the best resource to help estimate cloud costs, because it only shows the rules and procedures for managing the on-premises server cluster, such as the roles and responsibilities, the service level agreements, the security and compliance standards, and the backup and recovery plans. Resource management policy can help to ensure the quality and reliability of the server cluster, but it does not provide enough information about the actual usage and performance of the servers, which are more critical for cloud cost estimation5 References: 1: https://www.ibm.com/cloud/blog/how-to-estimate-cloud-costs-a-pricing- crash-course 2: https://www.comptia.org/training/books/cloud-essentials-clo-002-study- guide, page 48 3: https://www.ibm.com/cloud/architecture/ architectures/server-cluster 4: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, page 50 5: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, page 52

• Question 149:

  A company wants to process a batch job in a faster, cost-effective manner. Which of the following is the BEST solution?

  A. Implement right-sizing.

  B. Increase CPU usage.

  C. Utilize spot instances.

  D. Add storage.

  Correct Answer: C

  Explanation: Spot instances are cloud computing resources that are available at a lower price than the regular on-demand price, but can be interrupted and reclaimed by the cloud provider at any time1. Spot instances are ideal for batch jobs that have flexible completion times and can tolerate failures, as they can provide faster and cheaper computing power than regular instances2. Spot instances can also be combined with other pricing options, such as on-demand or reserved instances, to optimize the performance and cost of batch jobs3. Implementing right-sizing is a technique of adjusting the size and type of cloud resources to match the actual needs and usage patterns of an application4. Right-sizing can help reduce the cost and improve the efficiency of cloud resources, but it does not necessarily make the batch job faster, as it depends on the workload and demand of the job. Increasing CPU usage is a measure of how much processing power is being consumed by an application or a system. Increasing CPU usage can make the batch job faster, but it can also increase the cost and risk of overloading the system. Increasing CPU usage is not a solution by itself, but rather a consequence of using more or larger cloud resources. Adding storage is a process of increasing the amount or capacity of data that can be stored in the cloud. Adding storage can help store more data or backup data for the batch job, but it does not directly affect the speed or cost of the batch job, as it depends on the type and performance of the storage service.
