• Question 201:

  Which of the following BEST represents a successful presentation to a customer of the working result of a new cloud feature?

  A. Benchmark
  B. Proof of concept
  C. Baseline
  D. Feasibility study
  B. Proof of concept

  ---

  Explanation/Reference:

  A proof of concept (PoC) is a way to demonstrate that a new cloud feature is feasible and works as intended. A PoC is usually limited to the technical requirements of the feature and does not involve the user interface or user feedback. A PoC is used to show the customer the working result of the new cloud feature and to convince them to adopt the solution12. A PoC is different from a benchmark, which is a measure of the performance or quality of a system or product. A PoC is also different from a baseline, which is a reference point or standard for comparison. A PoC is also different from a feasibility study, which is an analysis of the viability and benefits of a project or idea3.

  C. Review the storage usage reports.
  D. Review the network ingress reports.
  E. Employ resource tagging.
  F. Review the compute usage reports.
  E. Employ resource tagging.
  F. Review the compute usage reports.

  ---

  Explanation/Reference:

  Resource tagging is the process of applying metadata tags to cloud resources, such as servers, storage, or network, that contain information about the resource's associated workload, environment, ownership, or other attributes. Resource

  tagging can help with identifying, organizing, and managing cloud resources, as well as tracking their cost and usage1. By employing resource tagging, the company can assign tags to the servers that indicate which department owns them,

  and use those tags to filter and report on the resource consumption and billing.

  Compute usage reports are reports that provide detailed information about the usage of compute resources, such as servers, in a cloud environment. Compute usage reports can show metrics such as CPU, memory, disk, or network

  utilization, as well as the duration and frequency of usage2. By reviewing the compute usage reports, the company can monitor the performance and demand of the servers, and identify the causes and patterns of the spikes in CPU usage.

  Compute usage reports can also help with optimizing the compute resources, such as scaling, right-sizing, or consolidating the

• Question 204:

  Which of the following risks is MOST likely a result of vendor lock-in?

  A. Premature obsolescence
  B. Data portability issues
  C. External breach
  D. Greater system vulnerability
  B. Data portability issues

  ---

  Explanation/Reference:

  Data portability is the ability to move data from one cloud service provider to another without losing functionality, quality, or security. Vendor lock-in is a situation where a customer becomes dependent on a particular cloud service provider and faces high switching costs, lack of interoperability, and contractual obligations. Vendor lock-in can result in data portability issues, as the customer may have difficulty transferring their data to a different cloud service provider if they are dissatisfied with the current one or want to take advantage of better offers. Data portability issues can affect the customer's flexibility, agility, and cost-efficiency in the cloud123. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 1: Cloud Principles and Design, pages 19-20.

• Question 205:

  Which of the following techniques helps an organization determine benchmarks for application performance within a set of resources?

  A. Auto-scaling
  B. Load testing
  C. Sandboxing
  D. Regression testing
  B. Load testing

  ---

  Explanation/Reference:

  Load testing is the technique that helps an organization determine benchmarks for application performance within a set of resources. Load testing is the process of simulating a high volume of user requests or traffic to a cloud application or service, and measuring its response time, throughput, availability, and reliability. Load testing can help an organization to evaluate the performance and scalability of the cloud application or service, as well as to identify and resolve any bottlenecks, errors, or failures. Load testing can also help the organization to optimize the resource utilization and allocation, and to plan for future growth or peak demand. Load testing can be done using various tools, such as JMeter, LoadRunner, or BlazeMeter12 References: CompTIA Cloud Essentials+ Certification Exam Objectives3, CompTIA Cloud Essentials+ Study Guide, Chapter 6: Cloud Connectivity and Load Balancing4, Cloud Essentials+ Certification Training2

• Question 206:

  A company is considering moving its database application to a public cloud provider. The application is regulated and requires the data to meet confidentiality standards. Which of the following BEST addresses this requirement?

  A. Authorization
  B. Validation
  C. Encryption
  D. Sanitization
  C. Encryption

  ---

  Explanation/Reference:

  Encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Encryption is the best way to address the requirement of data confidentiality, as it ensures that only authorized parties can access and understand the data, while unauthorized parties cannot. Encryption can protect data at rest, in transit, and in use, which are the three possible states of data in cloud computing environments1. Encryption can also help comply with various regulations and standards that require data protection, such as GDPR, HIPAA, or PCI DSS2. Authorization, validation, and sanitization are not the best ways to address the requirement of data confidentiality, as they do not provide the same level of protection as encryption. Authorization is the process of granting or denying access to data or resources based on the identity or role of the user or system. Authorization can help control who can access the data, but it does not prevent unauthorized access or leakage of the data3. Validation is the process of verifying the accuracy, completeness, and quality of the data. Validation can help ensure the data is correct and consistent, but it does not prevent the data from being exposed or compromised4. Sanitization is the process of removing sensitive or confidential data from a storage device or a data set. Sanitization can help prevent the data from being recovered or reused, but it does not protect the data while it is stored or processed5.

• Question 207:

  A project manager is interested in the notification process a CSP follows after discovering a breach of customer data. Which of the following is MOST likely to provide the necessary information?

  A. Communication plans
  B. Incident response policy
  C. Service level agreement
  D. Access controls
  C. Service level agreement

  ---

  Explanation/Reference:

  A service level agreement (SLA) is a contract between a cloud service provider (CSP) and a customer that defines the level of service, performance, availability, and responsibilities of both parties1. An SLA may also include the notification process a CSP follows after discovering a breach of customer data, such as the time frame, the communication channels, the content and format of the notification, and the remediation actions2. A communication plan is a document that outlines the objectives, strategies, and tactics for communicating with different stakeholders, but it may not specify the details of the breach notification process3. An incident response policy is a set of guidelines and procedures for responding to security incidents, such as identifying, containing, analyzing, and recovering from them, but it may not be shared with the customer by the CSP4. Access controls are the mechanisms and policies that regulate who can access what resources and data in a cloud environment, but they are not related to the breach notification process5. References:

• Question 208:

  A company deploys a data management capability that reduces RPO. Which of the following BEST describes the capability needed?

  A. Locality
  B. Replication
  C. Portability
  D. Archiving
  B. Replication

  ---

  Explanation/Reference:

  Replication is a data management capability that involves creating and maintaining copies of data across multiple locations or systems1. Replication can help reduce the Recovery Point Objective (RPO) of an application, which is the maximum acceptable amount of data loss measured in time2. By replicating data frequently and consistently, the risk of losing data in the event of a disruption or failure is minimized, as the data can be restored from the most recent replica. Replication can also improve the availability, performance, and scalability of an application, as the data can be accessed from multiple sources and distributed across different regions3. Locality is a data management capability that refers to the physical location or proximity of data to the users or applications that access it4. Locality can affect the latency, bandwidth, and cost of data transfer, as well as the compliance with data sovereignty and privacy regulations. Locality does not directly reduce the RPO of an application, but rather influences the choice of where to store and replicate data. Portability is a data management capability that refers to the ease of moving data across different platforms, systems, or environments. Portability can enable the interoperability, integration, and migration of data, as well as the flexibility and agility of data management. Portability does not directly reduce the RPO of an application, but rather enables the use of different data sources and destinations.

  Archiving is a data management capability that involves moving or copying data that is no longer actively used to a separate storage device or system for long-term retention. Archiving can help optimize the storage space, performance, and

  cost of data, as well as comply with data retention and preservation policies. Archiving does not directly reduce the RPO of an application, but rather preserves the historical data for future reference or analysis. References: CompTIA Cloud

• Question 209:

  An organization's servers are experiencing performance degradation from oversubscription of memory in the virtual environment and exhausted physical RAM.

  Which of the following cloud computing characteristics would BEST address the issue?

  A. Availability
  B. Elasticity
  C. Pay-as-you-go
  D. Self-service
  B. Elasticity

  ---

  Explanation/Reference:

  Elasticity is the cloud computing characteristic that allows the cloud service to scale up or down the resources dynamically according to the demand. Elasticity can help the organization address the issue of performance degradation from oversubscription of memory in the virtual environment and exhausted physical RAM by automatically allocating more memory resources to the servers when needed and releasing them when not needed. This way, the organization can avoid the risk of running out of memory and ensure optimal performance of the servers.

• Question 210:

  Which of the following is MOST likely to use a CDN?

  A. Realty listing website
  B. Video streaming service
  C. Email service provider
  D. Document management system
  B. Video streaming service

  ---

  Explanation/Reference:

  A CDN (content delivery network) is a network of distributed servers that store and deliver content to users based on their geographic location and network conditions. A CDN can improve the performance, availability, scalability, and security of web-based applications and services by reducing the latency, bandwidth, and load on the origin server. A CDN is most likely to be used by a video streaming service, which typically involves large amounts of data, high demand, and diverse audiences. A video streaming service can benefit from using a CDN by caching and streaming the video content from the nearest or best-performing server to the user, thus enhancing the user experience and reducing the cost and complexity of the service. A realty listing website is a web-based application that allows users to search, view, and compare properties for sale or rent. A realty listing website may use a CDN to improve the performance and availability of the website, especially if it has a large number of images, videos, or other media files. However, a realty listing website is not as likely to use a CDN as a video streaming service, since the content is not as dynamic, the demand is not as high, and the audience is not as diverse. An email service provider is a company that offers email hosting, management, and delivery services to users. An email service provider may use a CDN to improve the security and reliability of the email service, especially if it has a large number of users, messages, or attachments. However, an email service provider is not as likely to use a CDN as a video streaming service, since the content is not as public, the performance is not as critical, and the location is not as relevant. A document management system is a software application that allows users to create, store, organize, and share documents. A document management system may use a CDN to improve the scalability and accessibility of the document storage and retrieval, especially if it has a large number of documents, users, or collaborators. However, a document management system is not as likely to use a CDN as a video streaming service, since the content is not as large, the demand is not as variable, and the audience is not as global.
