CompTIA CV0-004 Online Questions & Answers

• Question 161:

  An administrator needs to adhere to the following requirements when moving a customer's data to the cloud:

  1. The new service must be geographically dispersed.

  2. The customer should have local access to data 3. Legacy applications should be accessible.

  Which of the following cloud deployment models is most suitable?

  A. On-premises
  B. Private
  C. Hybrid
  D. Public
  C. Hybrid

  ---

  Explanation

  A hybrid cloud deployment model is most suitable given the requirements. This model combines on-premises infrastructure (or private cloud) with public cloud services, providing geographic dispersion while allowing local access to data. It also facilitates the use of legacy applications that might not be well-suited for a full public cloud environment.References: The hybrid model is a fundamental concept within the CompTIA Cloud+ curriculum, under the section of Cloud Concepts, that explains deployment models.

• Question 162:

  A company has developed an online trading platform. The engineering team selected event-based scaling for the platform's underlying resources. The platform resources scale up with every 2,000 subscribed users. The engineering team finds out that although compute utilization is low, scaling is still occurring.

  Which of the following statements best explains why this is the case?

  A. Event-based scaling does not scale down resources.
  B. Event-based scaling should not be triggered at the 2,000-user frequency.
  C. Event-based scaling should not track user subscriptions.
  D. Event-based scaling does not take resource load into account.
  D. Event-based scaling does not take resource load into account.

  ---

  Explanation

  Event-based scaling triggers based on specific events, such as the number of user subscriptions in this case. It does not necessarily account for the actual load or utilization of compute resources. This is why the platform's resources continue to scale up even though compute utilization is low; the scaling decision is being made based on the number of subscribed users rather than the current resource usage.

• Question 163:

  A cloud solution needs to be replaced without interruptions. The replacement process can be completed in phases, but the cost should be kept as low as possible.

  Which of the following is the best strategy to implement?

  A. Blue-green
  B. Rolling
  C. In-place
  D. Canary
  B. Rolling

  ---

  Explanation

  A rolling strategy is the best to implement when needing to replace a cloud solution without interruptions and keeping costs low. This approach updates or replaces parts of the system gradually with minimal downtime and allows for a phased implementation.

• Question 164:

  Which of the following is an auditing procedure that ensures service providers securely manage the data to protect the interests of the organization and the privacy of its clients?

  A. CIS
  B. ITIL
  C. SOC2
  D. ISO 27001
  C. SOC2

  ---

  Explanation

  SOC2 (Service Organization Control 2) is an auditing procedure that ensures service providers securely manage data to protect the interests of an organization and the privacy of its clients. SOC2 is specifically designed for service providers storing customer data in the cloud, making it pertinent for data management and privacy.

  References: SOC2 and its role in auditing and ensuring secure data management by cloud service providers are part of the compliance standards and regulations included in the CompTIA Cloud+ certification material.

• Question 165:

  A government agency in the public sector is considering a migration from on premises to the cloud. Which of the following are the most important considerations for this cloud migration? (Select two).

  A. Compliance
  B. laaS vs. SaaS
  C. Firewall capabilities
  D. Regulatory
  E. Implementation timeline
  F. Service availability
  A. Compliance
  D. Regulatory

  ---

  Explanation

  For a government agency considering cloud migration, compliance and regulatory considerations are of utmost importance. The agency must ensure that the migration aligns with legal requirements, industry standards, and government regulations specific to the public sector.

  References: Compliance and regulatory considerations are crucial factors in the cloud migration process for government entities, as emphasized in the CompTIA Cloud+ certification.

• Question 166:

  Which of the following refers to the idea that data should stay within certain borders or territories?

  A. Data classification
  B. Data retention
  C. Data sovereignty
  D. Data ownership
  C. Data sovereignty

  ---

  Explanation

  Data sovereignty refers to the concept that data is subject to the laws and governance structures within the nation it is collected or stored. It implies that regardless of where a company's data is stored, the data must comply with the laws of the country where it is physically located.

  References: The principle of data sovereignty is a critical consideration in international cloud services and is included in the governance, risk, and compliance domain of CompTIA Cloud+.

• Question 167:

  A cloud engineer wants to replace the current on-premises. unstructured data storage with a solution in the cloud. The new solution needs to be cost-effective and highly scalable. Which of the following types of storage would be best to use?

  A. File
  B. Block
  C. Object
  D. SAN
  C. Object

  ---

  Explanation

  Object storage is ideal for cost-effective and highly scalable unstructured data. It allows for the storage of massive amounts of unstructured data in a flat namespace and is not constrained by the rigid structures of file or block storage. Object storage is highly durable and designed for high levels of scalability and accessibility.

  References: The suitability of object storage for unstructured data and scalability is a part of cloud storage technologies covered in CompTIA Cloud+ materials.

• Question 168:

  A cloud networking engineer is troubleshooting the corporate office's network configuration. Employees in the IT and operations departments are unable to resolve IP addresses on all devices, and the IT department cannot establish a connection to other departments' subnets. The engineer identifies the following configuration currently in place to support the office network:

  

  Each employee needs to connect to the network with a maximum of three hosts. Each subnet must be segregated, but the IT department must have the ability to communicate with all subnets.

  Which of the following meet the IP addressing and routing requirements? (Select two).

  A. Modifying the subnet mask to 255 255 254.0 for IT and operations departments
  B. Configuring static routing to allow access from each subnet to 10.1.40.1
  C. Modifying the BYOD policy to reduce the volume of devices that are allowed to connect to the corporate network
  D. Configuring static routing to allow access from 10.1.30.1 to each subnet
  E. Combining the subnets and increasing the allocation of IP addresses available to support three hosts for each employee
  F. Modifying the subnet mask to 255.255.255.128 for the IT and operations departments
  D. Configuring static routing to allow access from 10.1.30.1 to each subnet
  F. Modifying the subnet mask to 255.255.255.128 for the IT and operations departments

  ---

  Explanation

  To meet the requirements of allowing the IT department to communicate with all subnets while keeping each department segregated and ensuring a maximum of three hosts per employee, two actions are required. First, configuring static routing from the IT subnet (10.1.30.1) to each of the other subnets would establish the necessary connectivity. Second, modifying the subnet mask to 255.255.255.128 for the IT and operations departments would provide the needed number of host addresses while maintaining subnet segregation.

  References: This solution is based on networking and subnetting principles, which are part of the foundational knowledge for cloud networking within the CompTIA Cloud+ framework.
