CompTIA CV0-003 Online Questions & Answers

• Question 421:

  A system administrator is migrating a bare-metal server to the cloud. Which of the following types of migration should the systems administrator perform to accomplish this task?

  A. V2V
  B. V2P
  C. P2P
  D. P2V
  D. P2V

  ---

  Explanation

  P2V (Physical to Virtual) is a type of migration that converts a physical server into a virtual machine (VM). P2V migration can help to move a bare-metal server to the cloud by creating an image of its disk and configuration and uploading it to a cloud platform that supports VM creation from custom images.

• Question 422:

  A cloud administrator updates the syslog forwarder configuration on a local server in production to use a different port. The development team is no longer receiving the audit logs from that server. However, the security team can retrieve and search the logs for the same server. Which of the following is MOST likely the issue?

  A. The development team is not looking at the correct server when querying for the logs.
  B. The security team has greater permissions than the development team.
  C. The audit logging service has been disabled on the server.
  D. The development team's syslog server is configured to listen on the wrong port.
  B. The security team has greater permissions than the development team.

• Question 423:

  An administrator needs to back up all the data from each VM daily while also saving space. Which of the following backup types will BEST fit this scenario?

  A. Differential
  B. Incremental
  C. Synthetic full
  D. Full
  B. Incremental

  ---

  Explanation

  Incremental backups only back up the data that has changed since the last backup, which in this case is the previous day's backup. It saves space by not duplicating unchanged data and only capturing the changes made to the VMs since the last backup. This approach ensures efficient use of storage resources.

  Each day, the incremental backup will only capture and store the data that has been modified or added since the last backup. As a result, the size of each incremental backup is typically smaller than a full or differential backup, making it more space-efficient

• Question 424:

  After analyzing a web server's logs, a systems administrator sees that users are connecting to the company's application through HTTP instead of HTTPS. The administrator then configures a redirect from HTTP to HTTPS on the web server, and the application responds with a connection time-out message.

  Which of the following should the administrator verify NEXT?

  A. The TLS certificate
  B. The firewall rules
  C. The concurrent connection limit
  D. The folder permissions
  A. The TLS certificate

• Question 425:

  A cloud solutions architect has an environment that must only be accessed during work hours. Which of the following processes should be automated to best reduce cost?

  A. Scaling of the environment after work hours
  B. Implementing access control after work hours
  C. Shutting down the environment after work hours
  D. Blocking external access to the environment after work hours
  C. Shutting down the environment after work hours

  ---

  Explanation

  Shutting down the environment after work hours is the best process to automate to reduce cost, as it will stop incurring charges for the cloud resources that are not needed outside of work hours. Scaling, implementing access control, or blocking external access may still incur some costs for the cloud resources that are running or reserved, even if they are not fully utilized. Shutting down the environment can be automated using scripts, schedules, or triggers that can turn off or deallocate the cloud resources based on time or usage criteria12.

• Question 426:

  A storage administrator is reviewing the storage consumption of a SAN appliance that is running a VDI environment. Which of the following features should the administrator implement to BEST reduce the storage consumption of the SAN?

  A. Deduplication
  B. Thick provisioning
  C. Compression
  D. SDS
  A. Deduplication

  ---

  Explanation

  The best feature to reduce the storage consumption of a SAN appliance that is running a VDI environment is deduplication. Deduplication is a process that eliminates redundant or duplicate data blocks or files from a storage system and replaces them with pointers or references to a single copy of data. Deduplication can significantly reduce the storage consumption of a SAN appliance by removing unnecessary data and freeing up disk space.

• Question 427:

  The administrator of virtual infrastructure needs to provision block storage for a virtual machine on which a business critical application will be installed. Considering performance, which of the following describes how the administrator should attach the storage to the VM?

  A. Using NFS
  B. Using CIFS
  C. Using IPv6
  D. Using iSCSI
  D. Using iSCSI

• Question 428:

  A cloud engineer is responsible for managing two cloud environments from different MSPs. The security department would like to inspect all traffic from the two cloud environments.

  Which of the following network topology solutions should the cloud engineer implement to reduce long-term maintenance?

  A. Chain
  B. Star
  C. Mesh
  D. Hub and spoke
  D. Hub and spoke

  ---

  Explanation

  Hub and spoke is a type of network topology that consists of a central node or device (hub) that connects to multiple peripheral nodes or devices (spokes). Hub and spoke can help reduce long-term maintenance for managing two cloud environments from different MSPs, as it can simplify and centralize the network configuration and management by using the hub as a single point of contact and control for the spokes. Hub and spoke can also improve network performance and security, as it can reduce latency, bandwidth consumption, and network congestion by routing traffic through the hub.

• Question 429:

  An update is being deployed to a web application, and a systems administrator notices the cloud SQL database has stopped running. The VM is responding to pings, and there were not any configuration changes scheduled for the VM. Which of the following should the administrator check NEXT?

  A. Logs on the VM
  B. Firewall on the VM
  C. Memory on the VM
  D. vGPU performance on the VM
  A. Logs on the VM

  ---

  Explanation

  Checking the logs on the VM is the next step that the administrator should take if the cloud SQL database has stopped running after an update deployment. Logs are records of events and activities that occur on a system or application. Logs can provide useful information for troubleshooting and identifying the root cause of an issue. The administrator should look for any errors, warnings, or messages that indicate what happened to the SQL database service and why it stopped running.

• Question 430:

  A company that utilizes an IaaS service provider has contracted with a vendor to perform a penetration test on its environment. The vendor is able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company.

  Which of the following BEST describes this attack?

  A. VM escape
  B. Directory traversal
  C. Buffer overflow
  D. Heap spraying
  A. VM escape

  ---

  Explanation

  VM escape is a type of attack that allows an attacker to break out of a virtual machine (VM) and access the host system or other VMs within the same cloud provider's environment. VM escape can exploit the vulnerabilities in the virtualization layer or hypervisor that separates and isolates the VMs from each other and from the host system. VM escape can result in serious consequences, such as compromising the security and privacy of other customers' data or resources, gaining unauthorized access to the cloud provider's infrastructure or services, or launching further attacks on other systems or networks. VM escape best describes the attack that was performed by a vendor who was able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company.
