CompTIA CompTIA Certifications CV0-004 Questions & Answers

• Question 181:

  Following a ransomware attack, the legal department at a company instructs the IT administrator to store the data from the affected virtual machines for a minimum of one year.

  Which of the following is this an example of?

  A. Recoverability

  B. Retention

  C. Encryption

  D. Integrity

  Correct Answer: B

  The instruction by the legal department to store data from the affected virtual machines for a minimum of one year is an example of data Retention. Retention policies are often driven by regulatory compliance requirements and dictate how long certain types of data must be kept before they can be securely disposed of.

• Question 182:

  A software engineer is integrating an application to the cloud that is WebSocket-based. Which of the following applications is the engineer most likely deploying?

  A. Image-sharing

  B. Data visualization

  C. Chat

  D. File transfer

  Correct Answer: C

  A chat application is most likely to be deployed when integrating a web socket-based application to the cloud. Web sockets provide full-duplex communication channels over a single, long-lived connection, which is ideal for real-time

  applications like chat services that require persistent connections between the client and server for instant data exchange.

  References: CompTIA Cloud+ materials cover cloud networking concepts, emphasizing the importance of choosing the right technologies, like web sockets, for specific application requirements to ensure efficient and responsive cloud-based

  services.

• Question 183:

  Which of the following types of storage provides the greatest performance advantage for a traditional relational database?

  A. File

  B. Object

  C. Block

  D. Ephemeral

  Correct Answer: C

  Block storage provides the greatest performance advantage for traditional relational databases due to its high performance and low-latency characteristics. Block storage allows databases to rapidly manage data in fixed-sized blocks, which is

  ideal for databases that require frequent read/write operations.

  References: Understanding different storage types and their use cases, including block storage for databases, is part of the cloud computing knowledge base covered in CompTIA Cloud+.

• Question 184:

  A cloud engineer is deploying a cloud solution that will be used on premises with need-to- know access. Which of the following cloud deployment models best meets this requirement?

  A. Community

  B. Public

  C. Private

  D. Hybrid

  Correct Answer: C

  A private cloud deployment model is the most appropriate when the requirement is for 'need-to-know' access, as it offers a more secure environment with resources dedicated to a single organization. It can be hosted on-premises or off-premises but is maintained on a private network, ensuring greater control over the data, security, and compliance when compared to other cloud models.

• Question 185:

  A cloud solutions architect needs to design a solution that will collect a report and upload it to an object storage service every time a virtual machine is gracefully or non-gracefully stopped. Which of the following will best satisfy this requirement?

  A. An event-driven architecture that will send a message when the VM shuts down to a log- collecting function that extracts and uploads the log directly from the storage volume

  B. Creating a webhook that will trigger on VM shutdown API calls and upload the requested files from the volume attached to the VM into the object-defined storage service

  C. An API of the object-defined storage service that will scrape the stopped VM disk and self-upload the required files as objects

  D. A script embedded on the stopping VM's OS that will upload the logs on system shutdown

  Correct Answer: A

  An event-driven architecture is suited for this scenario, where an event (like a VM shutdown) triggers a function to execute specific tasks (log collection and upload). This approach is efficient and ensures that the logs are collected and uploaded to an object storage service every time the VM is stopped, regardless of whether it is a graceful or non- graceful shutdown.

• Question 186:

  An administrator needs to provide a backup solution for a cloud infrastructure that enables the resources to run from another data center in case of a outage. Connectivity to the backup data center is via a third-party, untrusted network.

  Which of the following is the most important feature required for this solution?

  A. Deduplication

  B. Replication

  C. Compression

  D. Encryption

  E. Labeling

  Correct Answer: D

  When backing up data that will traverse a third-party, untrusted network, encryption is the most important feature to ensure the confidentiality and integrity of the data. Encryption will protect the data from potential interception or tampering

  during transit to the backup data center.

• Question 187:

  Given the following command:

  Sdocker pull images.comptia.org/user1/myimage:latest

  Which of the following correctly identifies images.comptia.org?

  A. Image registry

  B. Image creator

  C. Image version

  D. Image name

  Correct Answer: A

  In the Docker pull command given,images.comptia.orgrepresents the image registry. A Docker image registry is a collection of repositories that host Docker images. It is where images arestored and organized, and from where they can be

  pulled for deployment.

  References: Docker and container management concepts, including image registries, are part of the cloud services understanding in the CompTIA Cloud+ curriculum.

• Question 188:

  A cloud engineer is collecting web server application logs to troubleshoot intermittent issues. However, the logs are piling up and causing storage issues.

  Which of the following log mechanisms should the cloud engineer implement to address this issue?

  A. Splicing

  B. Rotation

  C. Sampling

  D. Inspection

  Correct Answer: B

  Log rotation is the mechanism the cloud engineer should implement to address the issue of logs piling up and causing storage issues. Log rotation involves automatically archiving old log files and creating new ones after a certain size or time period, preventing storage issues.

• Question 189:

  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

  Correct Answer: C

  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 190:

  An IT security team wants to ensure that the correct parties are informed when a specific user account is signed in. Which of the following would most likely allow an administrator to address this concern?

  A. Creating an alert based on user sign-in criteria

  B. Aggregating user sign-in logs from all systems

  C. Enabling the collection of user sign-in logs

  D. Configuring the retention of all sign-in logs

  Correct Answer: A

  To ensure that the correct parties are informed when a specific user account is signed in, the best action is to create an alert based on user sign-in criteria. This alert can notify administrators or security personnel when the specified event

  occurs.

  References: Security monitoring and alerting are critical components of managing cloud environments securely, as discussed in the CompTIA Cloud+ certification.
