• Question 151:

  After a cloud migration, a company hires a third party to conduct an assessment to detect any cloud infrastructure vulnerabilities. Which of the following BEST describes this process?

  A. Hardening
  B. Risk assessment
  C. Penetration testing
  D. Application scanning
  C. Penetration testing

  ---

  Explanation/Reference:

  Penetration testing is a simulated attack to assess the security of an organization's cloud-based applications and infrastructure. It is an effective way to proactively identify potential vulnerabilities, risks, and flaws and provide an actionable remediation plan to plug loopholes before hackers exploit them1. Penetration testing is also known as ethical hacking, and it involves evaluating the security of an organization's IT systems, networks, applications, and devices by using hacker tools and techniques2. Penetration testing can be applied to both on-premises and cloud-based environments, making it a more general and broader term2. Cloud penetration testing, on the other hand, is a specialized form of penetration testing that specifically focuses on evaluating the security of cloud-based systems and services. It is tailored to assess the security of cloud computing environments and addresses the unique security challenges presented by cloud service models (IaaS, PaaS, SaaS) and cloud providers23. After a cloud migration, a company hires a third party to conduct an assessment to detect any cloud infrastructure vulnerabilities. This process best describes cloud penetration testing, as it involves simulating real-world attacks and providing insights into the security posture of the cloud environment.

• Question 152:

  A company wants to ensure its existing functionalities are not compromised by the addition of a new functionality.

  Which of the following is the BEST testing technique?

  A. Regression
  B. Stress
  C. Load
  D. Quality
  A. Regression

  ---

  Explanation/Reference:

  Regression testing is the best testing technique to ensure that the existing functionalities are not compromised by the addition of a new functionality. Regression testing is the type of testing performed to ensure that a code change in software does not affect the product's existing functionality. This ensures that the product functions correctly with new functionality, bug fixes, or changes to existing features. To validate the impact of the shift, previously executed test cases are re-executed1. Regression testing can be done manually or by using automated tools. Some of the most commonly used tools for regression testing are Selenium, WATIR, QTP, RFT, Winrunner, and Silktest2.

• Question 153:

  A cloud developer chooses to use private key encryption for all traffic in a new application. Which of the following security concerns does this BEST describe?

  A. Integrity
  B. Confidentiality
  C. Availability
  D. Authorization
  B. Confidentiality

  ---

  Explanation/Reference:

  Private key encryption, also known as symmetric key encryption, is a method of encrypting data using a single secret key that is shared by both the sender and the receiver of the message1. Private key encryption ensures that only the authorized parties who have the same key can access the encrypted data, while preventing unauthorized parties from reading or modifying it. Therefore, private key encryption is mainly used to protect the confidentiality of data, which is the security concern that deals with preventing unauthorized disclosure of information2. Confidentiality is one of the three main goals of information security, along with integrity and availability. Integrity refers to the security concern that deals with preventing unauthorized modification or corruption of information. Availability refers to the security concern that deals with ensuring timely and reliable access to information2. Authorization, on the other hand, is not a security concern, but a security mechanism that deals with granting or denying access rights to information based on predefined policies and rules3. A cloud developer chooses to use private key encryption for all traffic in a new application. This best describes the security concern of confidentiality, as the developer wants to ensure that only the intended recipients can access the encrypted data, while keeping it secret from anyone else.

• Question 154:

  An architect recently discovered new opportunities the cloud can provide to the company. A business analyst is currently working with the architect to document the business use-case scenarios. Which of the following should be the architect's NEXT step?

  A. Initialize a PoC.
  B. Conduct a feasibility study.
  C. Perform a gap analysis.
  D. Gather cloud requirements.
  B. Conduct a feasibility study.

  ---

  Explanation/Reference:

  After documenting the business use-case scenarios, the architect's next step should be to conduct a feasibility study. A feasibility study is an analysis of the viability and suitability of a proposed solution or project, such as migrating to the cloud. A feasibility study evaluates the technical, operational, financial, legal, and ethical aspects of the solution, as well as the risks and benefits involved. A feasibility study helps the architect to determine if the solution is feasible, desirable, and achievable, and to identify any potential issues or challenges that may arise1. A feasibility study is one of the key components of a cloud assessment, which is a process of evaluating the readiness and suitability of an organization for cloud adoption1. A proof of concept (PoC) is a demonstration or prototype of a solution that shows how it works and what it can achieve. A PoC is usually done after a feasibility study, when the solution has been proven to be feasible and the requirements have been defined1. A gap analysis is a comparison of the current state and the desired state of a process, system, or organization. A gap analysis identifies the gaps or differences between the two states, and the actions or resources needed to close them. A gap analysis is usually done after a feasibility study and a PoC, when the solution has been validated and the goals have been established1. Gathering cloud requirements is the process of collecting and analyzing the needs and expectations of the stakeholders for the cloud solution. Gathering cloud requirements is usually done after a feasibility study and before a PoC, when the solution has been confirmed to be feasible and the scope has been defined1.

• Question 155:

  Which of the following is true about the use of technologies such as JSON and XML for cloud data interchange and automation tasks?

  A. It can cause cloud vendor lock-in
  B. The company needs to define a specific programming language for cloud management.
  C. The same message format can be used across different cloud platforms.
  D. It is considered an unsafe format of communication.
  C. The same message format can be used across different cloud platforms.

  ---

  Explanation/Reference:

  JSON and XML are both data serialization formats that allow you to exchange data across different applications, platforms, or systems in a standardized manner. They are independent of any programming language and can be used across different cloud platforms. They do not cause cloud vendor lock-in, as they are open and interoperable formats. They do not require the company to define a specific programming language for cloud management, as they can be parsed and processed by various languages. They are not considered unsafe formats of communication, as they can be encrypted and validated for security purposes.

• Question 156:

  Which of the following is a benefit of microservice applications in a cloud environment?

  A. Microservices are dependent on external shared databases found on cloud solutions.
  B. Federation is a mandatory component for an optimized microservice deployment.
  C. The architecture of microservice applications allows the use of auto-scaling.
  D. Microservice applications use orchestration solutions to update components in each service.
  C. The architecture of microservice applications allows the use of auto-scaling.

  ---

  Explanation/Reference:

  Microservice applications are composed of many smaller, loosely coupled, and independently deployable services, each with its own responsibility and technology stack1. One of the benefits of microservice applications in a cloud environment is that they can use auto-scaling, which is the ability to automatically adjust the amount of computing resources allocated to a service based on the current demand2. Auto-scaling can help improve the performance, availability, and cost-efficiency of microservice applications, as it allows each service to scale up or down according to its own needs, without affecting the rest of the application2. Auto-scaling can also help handle unpredictable or variable workloads, such as spikes in traffic or seasonal fluctuations2. Auto-scaling can be implemented using different cloud services, such as Google Kubernetes Engine (GKE) or Cloud Run, which provide both horizontal and vertical scaling options for microservice applications34.

• Question 157:

  A company has been running tests on a newly developed algorithm to increase the responsiveness of the application. The company's monthly bills for the testing have been much higher than expected.

  Which of the following documents should the company examine FIRST?

  A. Memory report
  B. Compute report
  C. Network report
  D. Storage report
  C. Network report

  ---

  Explanation/Reference:

  A network report is a document that provides information about the network usage and performance of a cloud service. It can help the company identify the network- related factors that may affect the responsiveness of the

  application, such as bandwidth, latency, jitter, packet loss, and throughput. A network report can also help the company monitor the network costs and optimize the network configuration to reduce the monthly bills.

  A memory report, a compute report, and a storage report are documents that provide information about the memory, compute, and storage resources of a cloud service, respectively. They can help the company understand the resource

  consumption and performance of the application, but they are not the first documents to examine for the responsiveness issue. References: CompTIA Cloud Essentials+ CLO-002 Certification Study Guide, Chapter 4: Operating in the Cloud,

• Question 158:

  Which of the following are the appropriate responses to risks?

  A. Mitigate, accept, avoid, validate
  B. Migrate, accept, avoid, transfer
  C. Mitigate, accept, avoid, transfer
  D. Migrate, accept, avoid, validate
  C. Mitigate, accept, avoid, transfer

  ---

  Explanation/Reference:

  According to the CompTIA Cloud Essentials+ CLO-002 Study Guide, there are four common risk response types: avoid, share or transfer, mitigate, and accept1. These are the appropriate responses to risks, depending on the risk type, assessment, and attitude. The other options are incorrect because they include terms that are not valid risk responses. For example, migrate is not a risk response, but a cloud deployment strategy. Validate is not a risk response, but a quality assurance technique.

• Question 159:

  An incident response team requires documentation for an email phishing campaign against a company's email server. Which of the following is the BEST resource to use to start the investigation?

  A. Audit and system logs
  B. Change management procedures
  C. Departmental policies
  D. Standard operating procedures
  A. Audit and system logs

  ---

  Explanation/Reference:

  Audit and system logs are the best resource to use to start the investigation of an email phishing campaign against a company's email server. Audit and system logs are records of events and activities that occur on a system or a network, such as user login, file access, configuration changes, or network traffic. Audit and system logs can help an incident response team to identify the source, scope, and impact of the phishing attack, as well as to collect evidence, trace the attack steps, and determine the root cause. Audit and system logs can also help the incident response team to evaluate the security posture and controls of the email server, and to recommend remediation and mitigation actions12 References: CompTIA Cloud Essentials+ Certification Exam Objectives3, CompTIA Cloud Essentials+ Study Guide, Chapter 7: Cloud Security, Cloud Essentials+ Certification Trainin

• Question 160:

  An IT team documented the procedure for upgrading an existing IT resource within the cloud. Which of the following BEST describes this procedure?

  A. Security procedure
  B. Incident management
  C. Change management
  D. Standard operating procedure
  C. Change management

  ---

  Explanation/Reference:

  Change management is the process of controlling the lifecycle of all changes to IT services, enabling beneficial changes to be made with minimum disruption and risk1. Change management involves documenting, assessing, approving, implementing, and reviewing changes to IT resources, such as hardware, software, configuration, or capacity2. Change management aims to ensure that changes are aligned with the business objectives, requirements, and expectations, and that they are delivered in a timely, efficient, and effective manner3. A procedure for upgrading an existing IT resource within the cloud is an example of change management, as it describes the steps and actions needed to make a change to the cloud service. A procedure for upgrading an IT resource should include the following elements4: The reason and objective for the upgrade The scope and impact of the upgrade The roles and responsibilities of the stakeholders involved in the upgrade The prerequisites and dependencies for the upgrade The schedule and timeline for the upgrade The risks and mitigation strategies for the upgrade The testing and validation methods for the upgrade The communication and notification plan for the upgrade The rollback and recovery plan for the upgrade The evaluation and feedback mechanism for the upgrade A security procedure is a set of rules and guidelines that define how to protect IT resources from unauthorized access, use, modification, or destruction5. A security procedure is not the same as a procedure for upgrading an IT resource, as it focuses on the security aspects of the IT service, rather than the change aspects. An incident management is the process of restoring normal service operation as quickly as possible after an unplanned disruption or degradation. An incident management is not the same as a procedure for upgrading an IT resource, as it focuses on the incident aspects of the IT service, rather than the change aspects. A standard operating procedure (SOP) is a document that provides detailed instructions on how to perform a routine or repetitive task or activity. A standard operating procedure is not the same as a procedure for upgrading an IT resource, as it focuses on the operational aspects of the IT service, rather than the change aspects.
