CompTIA CLO-002 Online Questions & Answers

• Question 21:

  A company recently launched the first version of an application. Based on customer feedback, the company identified the features that need to be incorporated in the next release. Which of the following will help the company understand the extra effort required to meet the customer requirements?

  A. Statement of work
  B. Baseline
  C. Benchmark
  D. Gap analysis
  D. Gap analysis

  ---

  Explanation/Reference:

  A gap analysis is the best option for helping the company understand the extra effort required to meet the customer requirements. A gap analysis is a step-by-step process for examining the current state of a system or process

  and comparing it with the desired future state, and then identifying the gaps or differences between them1. A gap analysis can help to determine the scope, feasibility, and priority of the changes or improvements needed to bridge the gap and

  achieve the desired outcomes2. A gap analysis can also help to estimate the resources, time, and cost involved in implementing the changes or improvements3.

  A gap analysis is different from the other options listed in the question, which are not directly related to understanding the extra effort required to meet the customer requirements. A statement of work is a document that describes the scope,

  objectives, deliverables, and terms and conditions of a project or contract4. A statement of work can help to define the expectations and responsibilities of the parties involved in the project or contract, but it does not provide a detailed analysis

  of the current and future states of the system or process. A baseline is a reference point or standard that is used to measure the performance or progress of a project or process. A baseline can help to track the changes or deviations from the

  original plan or goal, but it does not provide a comprehensive comparison of the current and future states of the system or process. A benchmark is a point of reference or criterion that is used to evaluate the quality or performance of a

  system or process against a best practice or industry standard. A benchmark can help to identify the strengths and weaknesses of the system or process, but it does not provide a specific assessment of the gaps or differences between the

  current and future states of the system or process.

• Question 22:

  Before conducting a cloud migration, a compliance team requires confirmation that sensitive data will remain close to their users. Which of the following will meet this requirement during the cloud design phase?

  A. Data locality
  B. Data classification
  C. Data certification
  D. Data validation
  A. Data locality

  ---

  Explanation/Reference:

  Data locality is the principle of storing data close to where it is used, such as in the same region, country, or jurisdiction. Data locality can improve the performance, security, and compliance of cloud applications, especially when dealing with sensitive data that is subject to legal or regulatory requirements. Data locality can also reduce the network latency and bandwidth costs associated with transferring data across long distances. Data locality can be achieved by choosing a cloud provider that has data centers in the desired locations, and by specifying the data placement and migration policies in the cloud design phase. Data locality is different from data classification, data certification, and data validation. Data classification is the process of categorizing data based on its sensitivity, value, and risk. Data certification is the process of verifying that data meets certain standards or criteria. Data validation is the process of checking that data is accurate, complete, and consistent.

• Question 23:

  A company has decided to replicate cloud resources in several different geographic locations. Which of the following terms BEST describes this approach?

  A. Disaster recovery
  B. Deduplication
  C. Redundancy
  D. Data sovereignty
  C. Redundancy

  ---

  Explanation/Reference:

  Redundancy is a term that describes the approach of replicating cloud resources in several different geographic locations. Redundancy can increase the availability, reliability, and performance of cloud services by providing backup or alternative resources in case of failures, disasters, or high demand. Redundancy can also reduce latency by serving users from the nearest location. Redundancy can be implemented at different levels, such as data, network, server, or application. For example, a geo- distributed database is a type of redundancy that offers asynchronous replication across two data centers or cloud regions1. Redundancy is different from disaster recovery, deduplication, and data sovereignty, which are other terms related to cloud computing. Disaster recovery is a term that describes the process of restoring normal operations after a disaster or disruption. Disaster recovery can involve using redundant resources, but it is not the same as redundancy. Deduplication is a term that describes the technique of eliminating redundant copies of data from a storage device, which can reduce the storage space required and improve the efficiency of the storage system. Deduplication does not involve replicating cloud resources in different locations, but rather consolidating and removing duplicates. Data sovereignty is a term that describes the legal and regulatory aspects of data storage and processing in different geographic locations. Data sovereignty can affect the choice of cloud regions and providers, as some countries or regions may have specific laws or regulations that govern the access, transfer, and protection of data. Data sovereignty does not imply redundancy, but rather compliance. Therefore, the correct term for replicating cloud resources in several different geographic locations is redundancy.

• Question 24:

  Which of the following is used to build and manage interconnections between cloud resources within the same cloud environment?

  A. Firewall
  B. Software-defined network
  C. Virtual private network
  D. Direct Connect
  B. Software-defined network

  ---

  Explanation/Reference:

  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.

• Question 25:

  Which of the following are examples of capital expenditures? (Select TWO).

  A. Cloud consultant fees
  B. Data center wiring
  C. Data center electric bill
  D. Server purchases
  E. Spot instances
  F. Disposable virtual machine
  B. Data center wiring
  E. Spot instances

  ---

  Explanation/Reference:

  Capital expenditures are costs that a business incurs to acquire or improve long-term assets that will provide benefits beyond the current year. Capital expenditures are also known as PPandE, which stands for Property, Plant, and Equipment. Capital expenditures are usually one-time purchases of fixed assets that have a high initial cost and a long useful life. Capital expenditures are recorded as assets on the balance sheet and depreciated over time12 Data center wiring and server purchases are examples of capital expenditures, because they are part of the physical infrastructure that supports the IT operations of a business. Data center wiring and server purchases have a high upfront cost and a long lifespan, and they provide benefits for several years. Data center wiring and server purchases are also recorded as assets on the balance sheet and depreciated over time34 Cloud consultant fees, data center electric bill, spot instances, and disposable virtual machines are not examples of capital expenditures, but rather operating expenses. Operating expenses are costs that a business incurs to run its day-to-day operations and generate revenue. Operating expenses are also known as OPEX, which stands for Operating Expenses. Operating expenses are usually recurring payments for variable or consumable resources that have a low cost and a short useful life. Operating expenses are recorded as expenses on the income statement and deducted from revenue to calculate profit12 Cloud consultant fees are operating expenses, because they are payments for professional services that help a business implement or optimize its cloud strategy. Cloud consultant fees are recurring payments that vary depending on the scope and duration of the project, and they do not result in the acquisition or improvement of any long-term assets. Cloud consultant fees are also recorded as expenses on the income statement and deducted from revenue to calculate profit5 Data center electric bill is an operating expense, because it is a payment for the utility service that powers the data center equipment. Data center electric bill is a recurring payment that varies depending on the consumption and the rate of electricity, and it does not result in the acquisition or improvement of any long-term assets. Data center electric bill is also recorded as an expense on the income statement and deducted from revenue to calculate profit. Spot instances and disposable virtual machines are operating expenses, because they are payments for cloud computing resources that are available on-demand and for a short duration. Spot instances and disposable virtual machines are recurring payments that vary depending on the usage and the market price of the resources, and they do not result in the acquisition or improvement of any long-term assets. Spot instances and disposable virtual machines are also recorded as expenses on the income statement and deducted from revenue to calculate profit.

• Question 26:

  Which of the following are considered secure access types of hosts in the cloud? (Choose two.)

  A. HTTPS
  B. HTTP
  C. SSH
  D. Telnet
  E. RDP
  F. FTP
  A. HTTPS
  C. SSH

  ---

  Explanation/Reference:

  HTTPS and SSH are considered secure access types of hosts in the cloud because they use encryption and authentication to protect the data and the identity of the users. HTTPS is a protocol that uses SSL or TLS to encrypt the

  communication between a web browser and a web server. SSH is a protocol that allows secure remote login and file transfer over a network. Both HTTPS and SSH prevent unauthorized access, eavesdropping, and tampering of the data in

  transit. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 3:

  Security in the Cloud, pages 83-84.

• Question 27:

  Which of the following results from implementing a proprietary SaaS solution when an organization does not ensure the solution adopts open standards? (Choose two.)

  A. Vendor lock-in
  B. Inability to enforce the SLA
  C. Lack of technical support
  D. Higher ongoing operational expenditure
  E. Integration issues
  F. Higher initial capital expenditure
  A. Vendor lock-in
  E. Integration issues

  ---

  Explanation/Reference:

  A proprietary SaaS solution is one that uses a specific vendor's software and platform, which may not be compatible with other vendors' solutions or industry standards. This can result in vendor lock-in, which means that the organization becomes dependent on the vendor and cannot easily switch to another provider or solution without significant costs or risks. Vendor lock-in can also limit the organization's ability to negotiate better terms or prices with the vendor. Integration issues can arise when the proprietary SaaS solution does not support open standards, which are widely accepted and interoperable protocols or formats that enable different systems or applications to communicate and exchange data. Open standards can facilitate integration with other cloud or on-premise solutions, as well as enhance portability and scalability of the cloud services. If the SaaS solution does not adopt open standards, the organization may face challenges or limitations in integrating the solution with its existing or future IT environment, which can affect the functionality, performance, and security of the cloud services. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 2: Cloud Concepts, Section 2.3: Cloud Service Models, p. 62-63.

• Question 28:

  A new company directive requires all departments to ensure intellectual property is kept within a country's borders. Which of the following concepts BEST represents this requirement?

  A. Data portability
  B. Data security
  C. Data locality
  D. Data sovereignty
  D. Data sovereignty

  ---

  Explanation/Reference:

  Data sovereignty is the concept that best represents the requirement for keeping intellectual property within a country's borders. Data sovereignty refers to the idea that data is subject to the laws and governance of the country in which it is stored or processed. Data sovereignty can have implications for data privacy, security, compliance, and access, as different countries may have different regulations, standards, or policies regarding data protection, ownership, or transfer. Data sovereignty can also affect the choice of cloud providers, as some cloud providers may store or process data in multiple locations across the world, which may not comply with the data sovereignty requirements of the customer or the country. Therefore, customers who need to ensure data sovereignty should carefully review the terms and conditions of the cloud provider, and choose the one that offers the appropriate data location, encryption, or isolation options12 References: CompTIA Cloud Essentials+ Certification Exam Objectives3, CompTIA Cloud Essentials+ Study Guide, Chapter 4: Cloud Storage2, Intellectual Property Localization1

• Question 29:

  A startup company wants to use a CRM application to manage its sales and support organizations. The company does not have any IT staff. Which of the following cloud computing models is MOST appropriate for this company to use?

  A. CaaS
  B. PaaS
  C. IaaS
  D. SaaS
  D. SaaS

  ---

  Explanation/Reference:

  SaaS stands for Software as a Service, which is a cloud computing model that provides ready-to-use software applications over the internet, such as CRM, email, or office suites. SaaS is the most appropriate cloud computing model for a startup company that wants to use a CRM application to manage its sales and support organizations, and does not have any IT staff. SaaS offers the following benefits for the company: SaaS does not require any installation, maintenance, or update of the software, as the cloud provider handles all the technical aspects of the service. The company can access the software through a web browser or a mobile app, without worrying about the underlying infrastructure, platform, or software. SaaS is scalable, flexible, and cost-effective, as the company can adjust the number of users or features of the software according to its needs and budget. The company only pays for what it uses, and can avoid the upfront costs of purchasing or licensing the software. SaaS is reliable, secure, and compliant, as the cloud provider ensures the availability, backup, and recovery of the software, as well as the protection of the data and the adherence to the relevant standards and regulations.

• Question 30:

  Which of the following is the result of performing a physical-to-virtual migration of desktop workstations?

  A. SaaS
  B. laaS
  C. VDI
  D. VPN
  C. VDI

  ---

  Explanation/Reference:

  VDI, or Virtual Desktop Infrastructure, is the result of performing a physical- to-virtual migration of desktop workstations. VDI is a technology that allows users to access and run desktop operating systems and applications from a centralized server in a data center or a cloud, instead of from a physical machine on their premises. VDI provides users with virtual desktops that are delivered over a network to various devices, such as laptops, tablets, or thin clients1. VDI offers several benefits, such as improved security, reduced costs, increased flexibility, and enhanced performance2. SaaS, or Software as a Service, is not the result of performing a physical-to-virtual migration of desktop workstations, but a cloud service model that provides ready-to-use software applications that run on the cloud provider's infrastructure and are accessed via a web browser or an API3. SaaS does not involve migrating desktop workstations, but using software applications that are hosted and managed by the cloud provider. IaaS, or Infrastructure as a Service, is not the result of performing a physical-to-virtual migration of desktop workstations, but a cloud service model that provides access to basic computing resources, such as servers, storage, network, and virtualization, that are hosted on the cloud provider's data centers and are rented on-demand. IaaS does not involve migrating desktop workstations, but renting infrastructure resources that can be used to host various workloads. VPN, or Virtual Private Network, is not the result of performing a physical-to-virtual migration of desktop workstations, but a technology that creates a secure and encrypted connection between a device and a network over the internet. VPN does not involve migrating desktop workstations, but connecting to a network that can provide access to remote resources or services. References: What is VDI?
