CompTIA CV0-003 Online Questions & Answers

• Question 411:

  A cloud administrator is upgrading a cloud environment and needs to update the automation script to use a new feature from the cloud provider. After executing the script, the deployment fails. Which of the following is the MOST likely cause?

  A. API incompatibility
  B. Location changes
  C. Account permissions
  D. Network failure
  A. API incompatibility

  ---

  Explanation

  API incompatibility is the most likely cause of the failure of an automation script to use a new feature from the cloud provider. API (Application Programming Interface) is a set of rules or specifications that defines how different software components or systems can communicate and interact with each other. API incompatibility is a situation where an API does not work or function properly with another software component or system due to differences or changes in versions, formats, parameters, etc. API incompatibility can cause errors or issues when using an automation script to deploy or configure cloud resources or services, especially if the script is not updated or modified according to the new API specifications.

• Question 412:

  A cloud administrator has created a new asynchronous workflow lo deploy VMs to the cloud in bulk. When the workflow is tested for a single VM, it completes successfully. However, if the workflow is used to create 50 VMs at once, the job fails. Which of the following is the MOST likely cause of the issue? (Choose two.)

  A. Incorrect permissions
  B. Insufficient storage
  C. Billing issues with the cloud provider
  D. No connectivity to the public cloud
  E. Expired API token
  F. Disabled autoscaling
  B. Insufficient storage
  F. Disabled autoscaling

  ---

  Explanation

  Insufficient storage could cause the deployment of 50 VMs to fail as the cloud may not have enough available storage to create the instances. Disabled autoscaling could also cause the deployment to fail as the workflow is set to deploy a large number of VMs at once, and without autoscaling, the cloud may not have the resources to handle the workload.

• Question 413:

  A systems administrator recently upgraded the processors in a web application host. Upon the next login, the administrator sees a new alert regarding the license being out of compliance.

  Which of the following licensing models is the application MOST likely using?

  A. Per device
  B. Per user
  C. Core-based
  D. Volume-based
  C. Core-based

  ---

  Explanation

  Core-based licensing is a type of licensing model that charges based on the number of processor cores in a system or server. Core-based licensing is often used by software vendors to align their pricing with the performance and capacity of modern hardware. Core-based licensing can also enable customers to optimize their licensing costs by choosing the appropriate hardware configuration for their needs. Upgrading the processors in a web application host can affect the core-based licensing of the application, as it may increase the number of cores that need to be licensed. This can result in an alert regarding the license being out of compliance if the license is not updated accordingly.

• Question 415:

  A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance has been slow since the images were upgraded from Windows 7 to Windows 10.

  This VDI environment is used to run simple tasks, such as Microsoft Office. The administrator investigates the virtual machines and finds the following settings:

  1.4 vCPU

  2.16GB RAM

  3.10Gb networking

  4.256MB frame buffer

  Which of the following MOST likely needs to be upgraded?

  A. vRAM
  B. vCPU
  C. vGPU
  D. vNIC
  C. vGPU

  ---

  Explanation

  A virtual graphics processing unit (vGPU) is a type of hardware or software that enables a VM to use the physical GPU resources of the host or server for graphics-intensive tasks. Upgrading the vGPU is most likely to solve the issue of VDI performance being slow since the images were upgraded from Windows 7 to Windows 10, as it can provide more graphics processing power and memory for the VMs. Upgrading the vGPU can also improve the user experience and productivity, as it can enhance the display quality and responsiveness of the VDI environment.

• Question 416:

  A cloud administrator is responsible for managing a VDI environment that provides end users with access to limited applications. Which of the following should the administrator make changes to when a new application needs to be provided?

  A. Application security policy
  B. Application whitelisting policy
  C. Application hardening policy
  D. Application testing policy
  B. Application whitelisting policy

  Explanation

• Question 417:

  A systems administrator audits a cloud application and discovers one of the key regulatory requirements has not been addressed. The requirement states that if a physical breach occurs and hard drives are stolen, the contents of the drives should not be readable. Which of the following should be used to address the requirement?

  A. Obfuscation
  B. Encryption
  C. EDR
  D. HIPS
  B. Encryption

  ---

  Explanation

  Encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Encryption can be used to protect data at rest or in transit from unauthorized access or theft. If a physical breach occurs and hard drives

  are stolen, encryption can prevent the contents of the drives from being readable by anyone who does not have the decryption key or algorithm.

• Question 418:

  A systems administrator is configuring network management but is concerned about confidentiality.

  Which of the following should the administrator configure to address this concern?

  A. Community strings
  B. IPSec tunnels
  C. ACLs
  D. SNMPv3
  D. SNMPv3

  ---

  Explanation

  SNMPv3 is the protocol that the administrator should configure to address the concern about confidentiality for network management. SNMP (Simple Network Management Protocol) is a standard protocol that allows network devices and systems to exchange information and perform management tasks. SNMPv3 is the latest version of SNMP that provides security enhancements, such as authentication, encryption, and access control, to protect the confidentiality, integrity, and availability of network data.

• Question 419:

  A local bank has all of its infrastructure in the cloud. An update was applied to the main database server at 5:00 a.m. on Monday morning, and the database was then corrupted and unusable. It had to be restored from backup. The last backup was taken the night before at 10:00 p.m. The database was then restored successfully, but seven hours' worth of data was lost, which is deemed unacceptable. Which of the following needs to be updated in the DR plan?

  A. Recovery point objective
  B. Statement of work
  C. Service-level agreement
  D. Recovery time objective
  A. Recovery point objective

  ---

  Explanation

  The recovery point objective (RPO) is a metric that defines the maximum amount of data that can be lost or acceptable data loss in the event of a disaster or disruption. The RPO determines how frequently the backups should be performed and how far back in time the recovery should go. In this case, the RPO needs to be updated in the DR plan, as seven hours' worth of data loss is deemed unacceptable. The RPO should be reduced to a lower value, such as one hour or less, to minimize the data loss and meet the business requirements.

• Question 420:

  A cloud administrator has been using a custom VM deployment script. After three months of use, the script no longer joins the LDAP domain. The cloud administrator verifies the account has the correct permissions. Which of the following is the MOST likely cause of the failure?

  A. Incorrect encryption ciphers
  B. Broken trust relationship
  C. Invalid certificates
  D. Expired password
  D. Expired password

  ---

  Explanation

  An expired password is the most likely cause of the failure of a custom VM deployment script that no longer joins the LDAP domain. LDAP (Lightweight Directory Access Protocol) is a protocol that allows access and management of directory services, such as user accounts, groups, permissions, etc., over a network. LDAP can be used to authenticate and authorize users or devices to access network resources or systems. An expired password is a password that has reached its validity period and needs to be changed or renewed. An expired password can prevent users or devices from joining or accessing an LDAP domain, as it may indicate that the account is inactive, compromised, or outdated.
