CompTIA CompTIA Cloud Essentials CLO-002 Questions & Answers

• Question 41:

  A software company that develops mobile applications is struggling with the complicated process of deploying the development, testing. QA. and staging environments. Which of the following cloud service models offers the BEST automated development environment for the software company?

  A. SaaS

  B. laaS

  C. PaaS

  D. CaaS

  Correct Answer: C

  Explanation: PaaS, or Platform as a Service, is a cloud service model that provides a complete, flexible, and cost-effective cloud platform for developing, running, and managing applications1. PaaS offers the best automated development environment for the software company, because it eliminates the need to install, configure, and maintain the hardware, software, and infrastructure required for application development and deployment. PaaS also provides access to a variety of tools, frameworks, languages, and services that can simplify and accelerate the development process. PaaS enables developers to focus on writing code, testing, and deploying applications, without worrying about the underlying platform. PaaS also supports continuous integration and delivery, which can automate the deployment of different environments, such as development, testing, QA, and staging2. SaaS, or Software as a Service, is 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 offer an automated development environment for the software company, because it does not allow developers to create or modify the software applications, only to use them as end-users. SaaS is suitable for applications that have standard features and functionalities, such as email, CRM, or ERP, but not for custom applications that require specific requirements and capabilities. IaaS, or Infrastructure as a Service, is 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 offer an automated development environment for the software company, because it still requires developers to install, configure, and manage the software stack, such as operating systems, middleware, databases, and development tools, on top of the infrastructure. IaaS provides more control and flexibility over the infrastructure, but also more complexity and responsibility for the developers. CaaS, or Containers as a Service, is a cloud service model that provides a platform for deploying and managing containerized applications on the cloud provider's infrastructure. CaaS does not offer an automated development environment for the software company, because it assumes that the applications are already developed and packaged into containers, which are isolated and portable units of software that include all the dependencies and configurations needed to run them. CaaS provides a way to orchestrate, scale, and secure the containers, but not to develop them. CaaS is suitable for applications that are designed with a microservices architecture, which divides the application into smaller and independent components that communicate with each other via APIs.

• Question 42:

  Which of the following should be enforced for billing recognition to allow department members to provision their own cloud resource?

  A. Sandboxing

  B. BYOL

  C. Resource tagging

  D. Reserved instances

  Correct Answer: C

  Explanation: Resource tagging is a method of assigning metadata to cloud resources, such as virtual machines, storage volumes, databases, or networks. Resource tags are key-value pairs that can be used for various purposes, such as identifying, organizing, grouping, filtering, or reporting on cloud resources. Resource tagging can also be used for billing recognition, which means tracking and allocating the costs of cloud resources to different departments, projects, or customers. By applying resource tags to cloud resources, department members can provision their own cloud resources and have their usage and costs automatically attributed to their department. Resource tags can also help department managers monitor and optimize their cloud spending, and enforce policies and budgets for their cloud resources. Sandboxing, BYOL, and reserved instances are not related to billing recognition. Sandboxing is a technique of creating isolated environments for testing or experimenting with cloud resources, without affecting the production environment. BYOL stands for bring your own license, which means using an existing software license for a cloud service, instead of purchasing a new license from the cloud provider. Reserved instances are a type of cloud pricing model that offers discounted rates for committing to a certain amount of cloud resources for a specific period of time.

• Question 43:

  A company wants to migrate mission-critical applications to the cloud. In order for technicians to build, decommission, and perform other routine functions, which of the following cloud characteristics would BEST satisfy this business requirement?

  A. Self-service

  B. Elasticity

  C. Broad network access

  D. Availability

  Correct Answer: A

  Explanation: 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:

• Question 44:

  Which of the following DevOps options is used to integrate with cloud solutions?

  A. Provisioning

  B. API

  C. SOA

  D. Automation

  Correct Answer: B

  API stands for Application Programming Interface, which is a set of rules and protocols that allow different software components or systems to communicate and exchange data. API is used to integrate with cloud solutions because it enables developers to access the cloud services and resources programmatically, without having to deal with the underlying infrastructure or platform details. API also allows for automation, scalability, and interoperability of cloud applications and services.

• Question 45:

  A systems administrator must select a CSP while considering system uptime and access to critical servers. Which of the following is the MOST important criterion when choosing the CSP?

  A. Elasticity

  B. Scalability

  C. Availability

  D. Serviceability

  Correct Answer: D

  Explanation: Encryption in transit is the process of protecting data from unauthorized access or modification while it is being transferred from one location to another, such as from an on-premises data center to a cloud service provider. Encryption in transit uses cryptographic techniques to scramble the data and make it unreadable to anyone who intercepts it, except for the intended recipient who has the key to decrypt it. Encryption in transit is one of the best approaches to optimize data security in an IaaS migration, as it reduces the risk of data breaches, tampering, or leakage during the data transfer. Encryption in transit can be implemented using various methods, such as Transport Layer Security (TLS), Secure Sockets Layer (SSL), Internet Protocol Security (IPsec), or Secure Shell (SSH). Encryption in transit is different from other options, such as reviewing the risk register, performing a vulnerability scan, or performing server hardening. Reviewing the risk register is the process of identifying, analyzing, and prioritizing the potential threats and impacts to the data and the cloud environment. Performing a vulnerability scan is the process of detecting and assessing the weaknesses or flaws in the data and the cloud infrastructure that could be exploited by attackers. Performing server hardening is the process of applying security measures and configurations to the cloud servers to reduce their attack surface and improve their resilience. While these options are also important for data security, they do not directly address the data protection during the migration process, which is the focus of the question.

• Question 46:

  A company purchased insurance due to the risks involved with a cloud migration project. Which of the following risk response strategies is this an example of?

  A. Mitigation

  B. Avoidance

  C. Acceptance

  D. Transference

  Correct Answer: D

  Explanation: Transference is a risk response strategy that involves shifting the responsibility or impact of a risk to a third party, such as an insurance company, a vendor, or a partner. By purchasing insurance, the company transferred the financial liability of the cloud migration project to the insurance provider, in case of any losses or damages. Transference does not eliminate the risk, but it reduces the exposure of the company to the risk12.

• Question 47:

  A large enterprise has the following invoicing breakdown of current cloud consumption spend:

  

  The level of resources consumed by each department is relatively similar. Which of the following is MOST likely affecting monthly costs?

  A. The servers in use by the marketing department are in an availability zone that is generally expensive.

  B. The servers in use by the accounting and IT operations departments are in different geographic zones with lower pricing.

  C. The accounting and IT operations departments are choosing to bid on non-committed resources.

  D. The marketing department likely stores large media files on its servers, leading to increased storage costs.

  Correct Answer: D

  Explanation: The marketing department likely stores large media files on its servers, leading to increased storage costs. This is because the marketing department is responsible for creating and distributing various types of digital content, such as videos, images, podcasts, and webinars, to promote the products and services of the enterprise. These media files tend to be large in size and require more storage space than other types of data, such as text documents or spreadsheets. Therefore, the marketing department consumes more storage resources than the other departments, which increases the monthly cloud costs for the enterprise.

• Question 48:

  An organization wants to migrate a locally hosted application to a PaaS model. The application currently runs on a 15-year-old operating system and cannot be upgraded.

  Which of the following should the organization perform to ensure the application will be supported in the cloud?

  A. Risk register

  B. Feasibility study

  C. Benchmarks

  D. Baseline

  Correct Answer: B

  Explanation: A feasibility study is a process of evaluating the viability of a project or an idea before committing resources and time to it. It helps to identify the potential benefits, costs, risks, and challenges of a proposed solution. A feasibility study is especially important when migrating an application to a cloud platform, as it can determine whether the application is compatible with the cloud provider's services, standards, and requirements. In this case, the organization wants to migrate a locally hosted application that runs on a 15-year-old operating system to a PaaS model. The application cannot be upgraded, which means it may not be supported by the cloud provider's platform. A feasibility study can help the organization to assess the technical and operational feasibility of the migration, as well as the financial and strategic implications. A feasibility study can also help the organization to compare different cloud providers and select the best one for their needs.

  A. Big Data

  B. Blockchain

  C. VDI

  D. Machine learning

  Correct Answer: D

  Explanation: Machine learning is a technology that enables a voice assistant to improve its product based on end user input. Machine learning is a branch of artificial intelligence that allows systems to learn from data and experience, without being explicitly programmed. Machine learning can help a voice assistant to understand natural language, recognize speech, generate responses, and adapt to user feedback. Machine learning can also help a voice assistant to personalize its service, by learning the preferences, habits, and needs of each user. Machine learning can make a voice assistant more intelligent, accurate, and user-friendly over time.

• Question 50:

  Which of the following concepts is the backup and recovery of data considered?

  A. Risk avoidance

  B. Confidentiality

  C. Integrity

  D. Availability

  Correct Answer: D

  Explanation: Backup and recovery of data is considered a concept of availability, which is one of the three pillars of information security, along with confidentiality and integrity. Availability means that data and systems are accessible and usable by authorized users when needed. Backup and recovery of data ensures that data can be restored in case of loss, corruption, or disaster, and that business operations can continue or resume with minimal downtime. Cloud backup and recovery involves creating and storing copies of data in a secondary, offsite storage location, and using the copies to restore the original data in the event of data loss1. Cloud backup and recovery offers many benefits, such as scalability, cost-effectiveness, reliability, and automation234.
