CompTIA CV0-004 Online Questions & Answers

• Question 221:

  A cloud engineer needs to determine a scaling approach for a payroll-processing solution that runs on a biweekly basis. Given the complexity of the process, the deployment to each new VM takes about 25 minutes to get ready.

  Which of the following would be the best strategy?

  A. Horizontal
  B. Scheduled
  C. Trending
  D. Event
  B. Scheduled

  ---

  Explanation

  For a biweekly payroll-processing solution that takes a significant amount of time to deploy to each new VM, the best scaling strategy is Scheduled scaling. This strategy involves preparing new instances in advance of when they are needed based on a known schedule, which in this case is the biweekly payroll process. By scheduling the scaling actions in advance, the cloud engineer ensures that the resources are ready when needed without incurring extra costs for running them all the time.

• Question 222:

  Which of the following is true of SSDs?

  A. SSDs do not have self-encrypting capabilities.
  B. SSDs have small storage capacities.
  C. SSDs can be used for high-IOP applications.
  D. SSDs are used mostly in cold storage.
  C. SSDs can be used for high-IOP applications.

  ---

  Explanation

  SSDs (Solid State Drives) are known for their high performance and can handle a high number of input/output operations per second (IOPS). This makes them ideal for applications and workloads thatrequire rapid access to storage, such as databases and high-performance computing applications.

• Question 223:

  A cloud solutions architect is designing a VM-based solution that requires reducing the cost as much as possible. Which of the following solutions will best satisfy this requirement?

  A. Using ephemeral storage on replicated VMs
  B. Creating Spot VMs in one availability zone
  C. Spreading the VMs across different regions
  D. Using provisioned IOPS storage
  B. Creating Spot VMs in one availability zone

  ---

  Explanation

  Using Spot VMs is a cost-effective solution as these are available at significantly reduced prices compared to standard instances. Spot VMs are ideal for workloads that can tolerate interruptions and are a way to take advantage of unused cloud capacity.

  References: The concept of Spot VMs and their cost benefits are included in the financial aspects of managing cloud resources, as per the CompTIA Cloud+ certification guidelines.

• Question 224:

  A cloud security analyst is concerned about security vulnerabilities in publicly available container images.

  Which of the following is the most appropriate action for the analyst to recommend?

  A. Using CIS-hardened images
  B. Using watermarked images
  C. Using digitally signed images
  D. Using images that have an application firewall
  A. Using CIS-hardened images

  ---

  Explanation

• Question 225:

  A security analyst confirms a zero-day vulnerability was exploited by hackers who gained access to confidential customer data and installed ransomware on the server.

  Which of the following steps should the security analyst take? (Select two).

  A. Contact the customers to inform them about the data breach.
  B. Contact the hackers to negotiate payment lo unlock the server.
  C. Send a global communication to inform all impacted users.
  D. Inform the management and legal teams about the data breach
  E. Delete confidential data used on other servers that might be compromised.
  F. Modify the firewall rules to block the IP addresses and update the ports.
  A. Contact the customers to inform them about the data breach.
  D. Inform the management and legal teams about the data breach

  ---

  Explanation

  After a zero-day exploit resulting in a data breach and ransomware installation, it is critical to inform affected customers about the breach and the potential impact on their data. Additionally, the management and legal teams should be notified to handle the situation in compliance with regulatory requirements and to coordinate an appropriate response.

  References: Handling security incidents and communication strategies after a data breach are crucial elements of the governance and risk compliance domains in CompTIA Cloud+.

• Question 226:

  Which of the following is the most cost-effective way to store data that is infrequently accessed?

  A. Cold site
  B. Hot site
  C. Off-site
  D. Warm site
  C. Off-site

  ---

  Explanation

  The most cost-effective way to store data that is infrequently accessed is typically an off-site storage service, often referred to as cold or archival storage. This type of storage is designed for data that is rarely accessed, providing lower storage costs.References: Data storage solutions and their cost implications, including off-site (cold or archival) storage for infrequently accessed data, are part of the cloud storage options discussed in CompTIA Cloud+.

• Question 227:

  Which of the following is a difference between a SAN and a NAS?

  A. A SAN works only with fiber-based networks.
  B. A SAN works with any Ethernet-based network.
  C. A NAS uses a faster protocol than a SAN
  D. A NAS uses a slower protocol than a SAN.
  D. A NAS uses a slower protocol than a SAN.

  ---

  Explanation

  A NAS (Network Attached Storage) typically uses file-level protocols such as NFS or SMB, which are generally considered slower and less efficient than the block-level protocols used by SANs (Storage Area Networks), such as iSCSI or Fibre Channel. SANs are designed for high performance and low latency, making them more suitable for applications requiring fast and efficient storage access.

• Question 228:

  Which of the following service options would provide the best availability for critical applications in the event of a disaster?

  A. Edge computing
  B. Cloud bursting
  C. Availability zones
  D. Multicloud tenancy
  C. Availability zones

  ---

  Explanation

  Availability zones provide the best availability for critical applications in the event of a disaster. They are distinct locations within a cloud region that are engineered to be isolated from failures in other availability zones, thus providing redundancy and failover capabilities, which is essential for maintaining high availability of critical applications.

  References: The concept of availability zones and their importance in disaster recovery and high availability is covered under the domain of Management and Technical Operations in the CompTIA Cloud+ objectives.

• Question 229:

  A systems administrator is configuring backups on a VM and needs the process to run as quickly as possible, reducing the bandwidth on the network during all times from Monday through Saturday. In the event of data corruption, the management team expects the mean time to recovery to be as low as possible.

  Which of the following backup methods can the administrator use to accomplish these goals?

  A. Incremental backup daily to the cloud
  B. Full backup on Sunday and incremental backups on all other days of the week
  C. Differential backup daily to the cloud
  D. Incremental backups during off-hours on Monday, Wednesday, and Friday
  B. Full backup on Sunday and incremental backups on all other days of the week

  ---

  Explanation

  To achieve a quick backup process and reduce bandwidth use, the administrator should perform a Full backup on Sunday and incremental backups on all other days of the week. This method ensures that only the changes made since the last full backup are copied, reducing the amount of data that needs to be transferred each time, and thus the time and bandwidth required.References: CompTIA Cloud+ Study Guide (Exam CV0-004) by Todd Montgomery and Stephen Olson

• Question 230:

  An administrator received a report that company data has been compromised. The compromise occurred on a holiday, and no one in the organization was working. While reviewing the logs from the holiday, the administrator noted the following details:

  

  The most appropriate action for the cloud security analyst to recommend is using CIS- hardened images. These images are pre-configured by the Center for Internet Security to provide security benchmark standards that help in mitigating vulnerabilities in publicly available container images.

  Which of the following accounts should the administrator disable to prevent a further breach?

  A. Cloud administrator
  B. Human resources manager
  C. Security engineer
  D. Software developer
  D. Software developer

  ---

  Explanation

  Based on the provided log details, the account of the Software Developer was used to gain unauthorized access. This account should be disabled to prevent further breaches, especially considering no one from the organization was working during the holiday, suggesting a compromised account.
