• Question 121:

  A company hired a DevOps engineer to move business systems to the cloud. The current systems administrator does not have scripting experience and has been deploying servers manually. Which of the following would BEST optimize this process?

  A. Infrastructure as code deployment model
  B. API integration to a cloud provider
  C. Load testing
  D. Continuous delivery/continuous integration
  A. Infrastructure as code deployment model

  ---

  Explanation/Reference:

  Infrastructure as code (IaC) is a key DevOps practice that involves the management of infrastructure, such as networks, compute services, databases, storages, and connection topology, in a descriptive model. IaC allows teams to develop and release changes faster and with greater confidence. IaC avoids manual configuration and enforces consistency by representing desired environment states via well-documented code in formats such as JSON. Infrastructure deployments with IaC are repeatable and prevent runtime issues caused by configuration drift or missing dependencies. IaC also helps teams to provision multiple test environments reliably on demand. Therefore, IaC would best optimize the process of moving business systems to the cloud and reduce the need for scripting experience and manual deployment.

• Question 122:

  Which of the following is a limitation of the SaaS cloud model?

  A. Users cannot choose the global location where their data will be stored
  B. It does not support integration with pre-existing identity engines.
  C. It does not scale to allow additional users.
  D. Users do not have full control over the software version and roadmap of the cloud solution.
  D. Users do not have full control over the software version and roadmap of the cloud solution.

  ---

  Explanation/Reference:

  One of the limitations of the SaaS cloud model is that users do not have full control over the software version and roadmap of the cloud solution. This means that users have to rely on the vendor to provide updates, patches, bug fixes, and new features for the software, and they may not be able to choose when or how to implement them. Users may also face compatibility issues with other applications or services if the vendor changes the software without prior notice or consultation. Users may also have limited or no access to the underlying code or configuration of the software, which may restrict their ability to customize or optimize the software for their specific needs.

• Question 123:

  A systems administrator is reviewing a disaster recovery option that requires little to no downtime in the event of a natural disaster.

  Which of the following BEST meets this requirement?

  A. Configure availability zones.
  B. Configure high availability.
  C. Configure geo-redundancy.
  D. Configure auto-scaling.
  C. Configure geo-redundancy.

  ---

  Explanation/Reference:

  Geo-redundancy is the process of replicating data to a distant region from the original cloud storage. This safeguards data from regional disaster or outages and ensures that the data is always accessible and available. Geo-redundancy is one of the disaster recovery options that requires little to no downtime in the event of a natural disaster.

• Question 124:

  Which of the following policies dictates when to grant certain read/write permissions?

  A. Access control
  B. Communications
  C. Department-specific
  D. Security
  A. Access control

  ---

  Explanation/Reference:

  Access control is a policy that dictates when to grant certain read/write permissions to users or systems. Access control is a key component of information security, as it ensures that only authorized and authenticated users can access the data and resources they need, and prevents unauthorized access or modification of data and resources1. Access control policies can be based on various factors, such as identity, role, location, time, or context2. Communications, department-specific, and security policies are not directly related to granting read/write permissions, although they may have some implications for access control. Communications policies are policies that define how information is exchanged and communicated within or outside an organization, such as the use of email, social media, or encryption3. Department-specific policies are policies that apply to specific functions or units within an organization, such as human resources, finance, or marketing. Security policies are policies that establish the overall goals and objectives of information security in an organization, such as the protection of confidentiality, integrity, and availability of data and systems.

• Question 125:

  A cloud administrator patched a known vulnerability in an operating system. This is an example of risk:

  A. transference
  B. avoidance.
  C. mitigation.
  D. acceptance.
  C. mitigation.

  ---

  Explanation/Reference:

  Patching a known vulnerability in an operating system is an example of risk mitigation. Risk mitigation is the process of reducing the impact or likelihood of a risk by implementing controls or countermeasures. By patching the vulnerability, the cloud administrator is preventing or minimizing the potential damage that could be caused by an exploit. Risk mitigation is one of the four main risk response strategies, along with risk avoidance, risk transference, and risk acceptance. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 5: Risk Management, page 1631 and page 1662.

• Question 126:

  A company migrated all of its infrastructure to the cloud. The cloud security team must review the security post-migration.

  Which of the following is the MOST appropriate task for the cloud security team to perform?

  A. Risk register
  B. Threat assessment
  C. Application scan
  D. Vulnerability scan
  D. Vulnerability scan

  ---

  Explanation/Reference:

  A vulnerability scan is a process of identifying and reporting potential security weaknesses in a system or network. A vulnerability scan can help detect misconfigurations, outdated software, missing patches, and other issues that could compromise the security of the cloud environment. A vulnerability scan is an appropriate task for the cloud security team to perform after migrating the infrastructure to the cloud, as it can help identify and remediate any security gaps that may have occurred during the migration process. A vulnerability scan can also help the cloud security team comply with the security standards and regulations that apply to the cloud service provider and the cloud customer. A risk register is a document that lists the identified risks, their likelihood, impact, and mitigation strategies for a project or organization. A risk register is not a post-migration task, but rather a pre-migration task that should be created and updated throughout the cloud migration process. A risk register can help the cloud security team assess and manage the risks associated with the cloud migration, and plan for contingencies and backups in case of any unforeseen events. A threat assessment is a process of identifying and analyzing the potential threats that could harm a system or network. A threat assessment can help the cloud security team determine the sources, motives, capabilities, and methods of the attackers, and prioritize the most critical and likely threats. A threat assessment is not a post-migration task, but rather a continuous task that should be performed regularly to monitor and respond to the evolving threat landscape. A threat assessment can help the cloud security team enhance the security posture and resilience of the cloud environment, and implement appropriate countermeasures and controls. An application scan is a process of testing and verifying the functionality and security of an application. An application scan can help detect and report any errors, bugs, vulnerabilities, or performance issues in an application. An application scan is not a post-migration task, but rather a development and deployment task that should be performed before and after launching an application in the cloud. An application scan can help the cloud security team ensure the quality and reliability of the application, and fix any issues that could affect the user experience or security of the application.

• Question 127:

  Which of the following metrics defines how much data loss a company can tolerate?

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

  ---

  Explanation/Reference:

  RPO stands for recovery point objective, which is the maximum amount of data loss that a company can tolerate in the event of a disaster, failure, or disruption. RPO is measured in time, from the point of the incident to the last valid backup of the data. RPO helps determine how frequently the company needs to back up its data and how much data it can afford to lose. For example, if a company has an RPO of one hour, it means that it can lose up to one hour's worth of data without causing significant harm to the business. Therefore, it needs to back up its data at least every hour to meet its RPO. RPO is different from other metrics such as RTO, TCO, MTTR, and ROI. RTO stands for recovery time objective, which is the maximum amount of time that a company can tolerate for restoring its data and resuming its normal operations after a disaster. TCO stands for total cost of ownership, which is the sum of all the costs associated with acquiring, maintaining, and operating a system or service over its lifetime. MTTR stands for mean time to repair, which is the average time that it takes to fix a faulty component or system. ROI stands for return on investment, which is the ratio of the net profit to the initial cost of a project or investment.

• Question 128:

  A business analyst is reviewing a software upgrade plan. The plan mentions the term "hash" value. Which of the following BEST represents what this term implies?

  A. Non-repudiation of data
  B. Integrity of data
  C. Confidentiality of data
  D. Availability of data
  B. Integrity of data

  ---

  Explanation/Reference:

  A hash value is a unique code that is generated by applying a mathematical algorithm to a piece of data. Hash values are used to ensure the integrity of data, which means that the data has not been altered or corrupted in any way. By comparing the hash value of the original data with the hash value of the received or stored data, one can verify that the data is identical and has not been tampered with. Hash values can also be used for digital signatures, which provide non-repudiation of data, meaning that the sender or owner of the data cannot deny its authenticity or origin. However, hash values alone do not provide confidentiality or availability of data, which are other aspects of data security. Confidentiality means that the data is protected from unauthorized access or disclosure, and availability means that the data is accessible and usable when needed. Hash values do not encrypt or hide the data, nor do they prevent data loss or downtime.

• Question 129:

  Which of the following BEST specifies how software components interoperate in a cloud environment?

  A. Federation
  B. Regression
  C. Orchestration
  D. API integration
  B. Regression

  ---

  Explanation/Reference:

  A disaster recovery plan (DRP) is a document that defines the procedures and resources needed to restore normal operations after a major disruption. A DRP typically includes the following elements: The scope and objectives of the plan The roles and responsibilities of the DR team The inventory and location of critical assets and resources The recovery strategies and procedures for different scenarios The testing and maintenance schedule for the plan The communication plan for internal and external stakeholders One of the key components of a DRP is the recovery sequence, which is the optimal, sequential order in which cloud resources should be recovered in the event of a major failure. The recovery sequence is based on the priority and dependency of the resources, as well as the recovery time objective (RTO) and recovery point objective (RPO) of the business. The recovery sequence helps to minimize the downtime and data loss, and ensure the continuity of the business operations. A recovery point objective (RPO) is the maximum acceptable amount of data loss measured in time. It indicates how often the data should be backed up and how much data can be restored after a disaster. A recovery time objective (RTO) is the maximum acceptable amount of time that a system or application can be offline after a disaster. It indicates how quickly the system or application should be restored and how much downtime can be tolerated by the business. An incident response plan (IRP) is a document that defines the procedures and actions to be taken in response to a security breach or cyberattack. An IRP typically includes the following elements: The scope and objectives of the plan The roles and responsibilities of the incident response team The incident identification and classification criteria The incident containment, eradication, and recovery steps The incident analysis and reporting methods The incident prevention and improvement measures A network topology diagram is a visual representation of the physical and logical layout of a network. It shows the devices, connections, and configurations of the network. A network topology diagram can help to identify the potential points of failure, the impact of a failure, and the recovery options for a network. However, it does not define the optimal, sequential order in which cloud resources should be recovered in the event of a major failure.

• Question 130:

  Due to local natural disaster concerns, a cloud customer is transferring all of its cold storage data to servers in a safer geographic region. Which of the following risk response techniques is the cloud customer employing?

  A. Avoidance
  B. Transference
  C. Mitigation
  D. Acceptance
  A. Avoidance

  ---

  Explanation/Reference:

  Avoidance is a risk response technique that involves changing the project plan to eliminate the risk or protect the project objectives from its impact. Avoidance can be done by modifying the scope, schedule, cost, or quality of the project. Avoidance is usually the most effective way to deal with a risk, but it may not always be possible or desirable. In this case, the cloud customer is transferring all of its cold storage data to servers in a safer geographic region, which means they are changing the location of their data storage to avoid the risk of a natural disaster affecting their data. This way, they are eliminating the possibility of losing their data due to a natural disaster in their original region. This is an example of avoidance as a risk response technique.
