• Question 211:

  Which of the following is achieved by implementing replication, redundancy, and disaster recovery?

  A. Improved performance
  B. Improved throughput
  C. Improved latency
  D. Improved availability
  D. Improved availability

  ---

  Explanation/Reference:

  Availability is the degree to which a system or service is accessible and functional when required. Availability can be measured by metrics such as uptime, downtime, and service level agreements (SLAs). Availability can be improved by implementing replication, redundancy, and disaster recovery strategies in the cloud. Replication is the process of creating and maintaining multiple copies of data or resources across different locations or regions. Redundancy is the provision of extra or backup components or systems to prevent or mitigate failures. Disaster recovery is the ability to restore normal operations after a disruptive event, such as a natural disaster, a cyberattack, or a human error. By implementing these strategies, cloud users can ensure that their data and services are always accessible and resilient to failures or disasters.

• Question 212:

  Which of the following BEST describes the open-source licensing model for application software?

  A. Software is free to use, but the source code is not available to modify.
  B. Modifications to existing software are not allowed.
  C. Code modifications must be submitted for approval.
  D. Source code is readily available to view and use.
  D. Source code is readily available to view and use.

  ---

  Explanation/Reference:

  The open-source licensing model for application software is a type of software license that allows anyone to access, modify, and distribute the source code of the software, subject to certain terms and conditions. The source code is the human- readable version of the software that contains the instructions and logic for how the software works. By making the source code available, open-source software licenses enable collaboration, innovation, and transparency among software developers and users. There are different types of open-source software licenses, such as permissive and copyleft licenses, that vary in the degree of freedom and restriction they impose on the use and modification of the software. However, the common characteristic of all open-source software licenses is that they grant the right to view and use the source code of the software. Therefore, option D is the best description of the open-source licensing model for application software. Option A is incorrect because it describes the opposite of the open- source licensing model. Software that is free to use, but the source code is not available to modify, is called closed-source or proprietary software. Option B is incorrect because it contradicts the open-source licensing model. Modifications to existing software are allowed under open-source software licenses, as long as they comply with the terms and conditions of the license. Option C is incorrect because it does not reflect the open-source licensing model. Code modifications do not need to be submitted for approval under open-source software licenses, although they may need to be shared with the original author or the community, depending on the license.

• Question 213:

  A business analyst is drafting a risk assessment.

  Which of the following components should be included in the draft? (Choose two.)

  A. Asset management
  B. Database type
  C. Encryption algorithms
  D. Certificate name
  E. Asset inventory
  F. Data classification
  E. Asset inventory
  F. Data classification

  ---

  Explanation/Reference:

  A risk assessment is a process of identifying, analyzing, and controlling hazards and risks within a situation or a place1. According to the CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), a risk assessment should include the following steps2: Identify the assets that are relevant to the scope of the assessment. Assets can be physical, such as hardware and software, or non-physical, such as data and information. Identify the threats and vulnerabilities that could affect the assets. Threats are sources of potential harm, such as natural disasters, cyberattacks, or human errors. Vulnerabilities are weaknesses or gaps in the security or protection of the assets, such as outdated software, misconfigured settings, or lack of encryption. Analyze the likelihood and impact of each threat-vulnerability pair. Likelihood is the probability of a threat exploiting a vulnerability, and impact is the severity of the consequences if that happens. The combination of likelihood and impact determines the level of risk for each pair. Evaluate the risks and prioritize them based on their level. Risks can be categorized as low, medium, high, or critical, depending on the organization's risk appetite and tolerance. Risk appetite is the amount of risk that the organization is willing to accept, and risk tolerance is the degree of variation from the risk appetite that the organization can endure. Implement appropriate controls to mitigate or reduce the risks. Controls are measures or actions that can prevent, detect, or correct the occurrence or impact of a risk. Controls can be administrative, technical, or physical, and they can have different functions, such as preventive, detective, corrective, deterrent, or compensating. Based on these steps, two components that should be included in the draft of a risk assessment are asset inventory and data classification. Asset inventory is the process of identifying and documenting the assets that are within the scope of the assessment1. Data classification is the process of categorizing data based on its sensitivity, value, and criticality to the organization3. These components are essential for determining the potential risks and impacts that could affect the assets and data, and for applying the appropriate controls and protection levels.

• Question 214:

  Which of the following is commonly used to forecast market trends?

  A. Serverless computing
  B. Data warehouse
  C. Machine learning
  D. Accelerated computing
  C. Machine learning

  ---

  Explanation/Reference:

  Machine learning is a branch of artificial intelligence that enables computers to learn from data and make predictions or decisions without being explicitly programmed. Machine learning can be used to forecast market trends by analyzing historical and current data, identifying patterns and relationships, and generating models that can extrapolate future outcomes. Machine learning can also adapt to changing data and environments, and improve its accuracy and performance over time1. The other options are not commonly used to forecast market trends: Serverless computing: This is a type of cloud computing that allows customers to run applications or functions without managing or provisioning servers. Serverless computing can reduce the operational and infrastructure costs, and improve the scalability and availability of the applications or functions. However, serverless computing is not directly related to forecasting market trends, although it can be used to deploy or run machine learning models or applications2. Data warehouse: This is a centralized repository that stores structured and historical data from various sources, such as databases, applications, or files. Data warehouse can support business intelligence and analytics, and provide consistent and reliable data for reporting and decision making. However, data warehouse is not a forecasting method, but rather a data storage and integration system, that can be used as an input for machine learning or other forecasting methods3. Accelerated computing: This is a type of computing that uses specialized hardware, such as graphics processing units (GPUs) or field-programmable gate arrays (FPGAs), to accelerate the performance of certain applications or tasks, such as machine learning, gaming, or video processing. Accelerated computing can enhance the speed and efficiency of the applications or tasks, and reduce the power consumption and costs. However, accelerated computing is not a forecasting method, but rather a computing platform, that can be used to support or enable machine learning or other forecasting methods4.

• Question 215:

  For which of the following reasons is the infrastructure as code technique used?

  A. To improve the ability to migrate applications to different cloud providers to avoid vendor lock-in.
  B. To specify the hardware configuration and system installation procedures in machine- readable formats.
  C. To capture the system configurations to track changes and remediate configuration drift.
  D. To assign server administration responsibilities to software developers for application deployments.
  C. To capture the system configurations to track changes and remediate configuration drift.

  ---

  Explanation/Reference:

  Infrastructure as code (IaC) is a software engineering approach that allows the provisioning and management of infrastructure resources using code and automation1. It involves defining infrastructure configurations and

  provisioning them through code, rather than manually configuring and managing infrastructure resources2. One of the main reasons for using IaC is to capture the system configurations to track changes and remediate configuration drift3.

  Configuration drift is the phenomenon where the actual state of an infrastructure resource deviates from its desired state over time due to manual interventions, updates, patches, or other factors. Configuration drift can cause inconsistencies,

  errors, and security issues in the infrastructure environment. IaC helps to prevent and detect configuration drift by storing the infrastructure configuration code in a version control system and applying it consistently across all environments.

  IaC also enables the use of automated testing and validation tools to verify the compliance and functionality of the infrastructure resources. By using IaC, DevOps teams can ensure that the infrastructure is always in a known and reproducible

  state, and that any changes are documented and traceable. References: 1: https://technology.gov.capital/infrastructure-as- code-iac/ 2: https://aws.amazon.com/what-is/iac/ 3: https://learn.microsoft.com/en- us/devops/deliver/what-isinfrastructure-as-code :

• Question 216:

  A requirement states that an application must be restored within six hours. Which of the following should be included in the SLA to satisfy this requirement?

  A. MTTR
  B. RPO
  C. ROI
  D. RTO
  D. RTO

  ---

  Explanation/Reference:

  The SLA should include the Recovery Time Objective (RTO) to satisfy this requirement. The RTO is the maximum acceptable time that an application or service can be unavailable after a disaster or disruption. It defines the target duration for restoring the functionality and performance of the application or service. The RTO is usually measured in hours or days, depending on the criticality of the application or service. In this case, the requirement states that the application must be restored within six hours, which means that the RTO should be six hours or less. The other options are not relevant to this requirement. The Mean Time to Repair (MTTR) is the average time that it takes to fix a faulty component or system. The Recovery Point Objective (RPO) is the maximum acceptable amount of data loss that can occur after a disaster or disruption. It defines the point in time to which the data must be restored. The RPO is usually measured in minutes or hours, depending on the frequency of data backups. The Return on Investment (ROI) is the ratio of the net profit to the initial cost of an investment. It measures the financial benefit of an investment over time.

• Question 217:

  A business is experiencing an outage of a customer-facing e-commerce website after a SaaS-based CDN upgrade. The RTO is 5 minutes or less, but it has already been 10 minutes since the outage. After 15 minutes, the CDN recovers for the outage. The business loses $25000 in revenue per minute of the outage. Which of the following is the financial impact to the business?

  A. $250000
  B. $350000
  C. $375000
  D. $400000
  C. $375000

  ---

  Explanation/Reference:

  The financial impact to the business is the amount of revenue lost due to the outage of the customer-facing e-commerce website. To calculate the financial impact, we can use the following formula: Financial impact = Revenue loss per minute x Outage duration Using this formula, we can find the financial impact as follows: Financial impact = $25000 x 15 minutes = $375000 Therefore, the financial impact to the business is $375000, which is the product of the revenue loss per minute and the outage duration. Option C is the correct answer. Option A is incorrect because it is the product of the revenue loss per minute and the RTO, which is the maximum acceptable outage duration, not the actual outage duration. Option B is incorrect because it is the product of the revenue loss per minute and the time elapsed since the outage, not the outage duration. Option D is incorrect because it is the product of the revenue loss per minute and the sum of the RTO and the outage duration, which is not relevant to the financial impact calculation.

• Question 218:

  The legal team is required to share legal proceedings with an outside council. The team uses SaaS fileshares. Which of the following policies will BEST state the requirements for sharing information with external parties?

  A. Information security policy
  B. Communication policy
  C. Resource management policy
  D. Identity control policy
  A. Information security policy

  ---

  Explanation/Reference:

  An information security policy is a document that defines the rules and guidelines for protecting the confidentiality, integrity, and availability of data and systems in an organization. It covers topics such as data classification, access control, encryption, backup, incident response, and compliance. An information security policy is essential for ensuring that data is shared securely with external parties, especially when using SaaS fileshares that may have different security standards and features than the organization's own systems. A communication policy, a resource management policy, and an identity control policy are all related to information security, but they are not as comprehensive and specific as an information security policy.
