CompTIA CompTIA Certifications CV0-003 Questions & Answers

• Question 71:

  A piece of software applies licensing fees on a socket-based model. Which of the following is the MOST important consideration when attempting to calculate the licensing costs for this software?

  A. The amount of memory in the server

  B. The number of CPUs in the server

  C. The type of cloud in which the software is deployed

  D. The number of customers who will be using the software

  Correct Answer: B

  The most important consideration when attempting to calculate the licensing costs for a piece of software that applies licensing fees on a socket-based model is the number of CPUs in the server. A socket-based model is a type of licensing model that charges based on the number of physical CPU sockets or slots on the server, regardless of how many cores or threads each CPU has. The systems administrator should count how many CPUs are installed on each server and multiply that by the licensing fee per socket to determine the total licensing cost for the software.

• Question 72:

  A company is deploying a public cloud solution for an existing application using lift and shift. The requirements for the applications are scalability and external access. Which of the following should the company implement? (Choose two.)

  A. A load balancer

  B. SDN

  C. A firewall

  D. SR-IOV

  E. Storage replication

  F. A VPN

  Correct Answer: AF

  The best options to implement for a public cloud solution for an existing application using lift and shift that requires scalability and external access are a load balancer and a VPN (virtual private network). A load balancer is a device or service that distributes incoming traffic across multiple servers or instances based on various criteria, such as availability, capacity, or performance. A load balancer can improve scalability by balancing the workload and optimizing resource utilization. A VPN is a technology that creates a secure and encrypted connection over a public network, such as the internet. A VPN can provide external access by allowing remote users or sites to connect to the cloud resources as if they were on the same private network.

• Question 73:

  A systems administrator is concerned about having two virtual database servers on the same host. Which of the following should be configured?

  A. Regions

  B. Anti-affinity

  C. Oversubscription

  D. Container

  Correct Answer: B

  The best way to prevent two virtual database servers from being on the same host is to configure anti-affinity. Anti-affinity is a feature that allows specifying which VMs or applications should not run on the same host or cluster. This can improve availability, performance, and security by avoiding resource contention, single point of failure, or interference between VMs or applications. The systems administrator should create an anti-affinity rule or policy for the two virtual database servers to ensure they are placed on different hosts. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 1.0 Configuration and Deployment, Objective 1.2 Given a scenario involving requirements for deploying an application in the cloud, select an appropriate solution design.

• Question 74:

  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

  Correct Answer: A

  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 75:

  A financial services company is considering its options for moving its infrastructure to the cloud. The company runs its critical database on a proprietary legacy mainframe, which cannot be hosted anywhere but in the data center. However, the company would like to migrate portions of the infrastructure to an external provider. Which of the following cloud deployment models would be the BEST option?

  A. Private

  B. Public

  C. Community

  D. Hybrid

  Correct Answer: D

• Question 76:

  A cloud administrator is monitoring a database system and notices an unusual increase in the read operations, which is causing a heavy load in the system. The system is using a relational database and is running in a VM. Which of the following should the administrator do to resolve the issue with minimal architectural changes?

  A. Migrate the relational database to a NoSQL database

  B. Use a cache system to store reading operations

  C. Create a secondary standby database instance

  D. Implement the database system using a DBaaS

  Correct Answer: B

  The best way to resolve the issue of an unusual increase in the read operations that is causing a heavy load in the system that is using a relational database and is running in a VM is to use a cache system to store reading operations. A cache system is a type of storage system that temporarily stores frequently accessed or recently used data in memory for faster retrieval. A cache system can reduce the load on the database system by serving the read requests from the cache instead of querying the database every time.

• Question 77:

  A financial industry services firm was the victim of an internal data breach, and the perpetrator was a member of the company's development team. During the investigation. one of the security administrators accidentally deleted the perpetrator's user data. Even though the data is recoverable, which of the following has been violated?

  A. Chain of custody

  B. Evidence acquisition

  C. Containment

  D. Root cause analysis

  Correct Answer: A

  The chain of custody is a process that documents and preserves the integrity and authenticity of evidence from the time it is collected until it is presented in court. The chain of custody includes information such as who collected, handled, stored, or transferred the evidence, when and where it was done, and how it was done. By accidentally deleting the perpetrator's user data, the security administrator has violated the chain of custody, as the evidence has been altered or destroyed and can no longer be used in court.

• Question 78:

  A systems administrator is troubleshooting an application that is configured to auto-scale with a minimum of two nodes and a maximum of four. The application will scale out if the CPU utilization of one of the nodes exceeds 80% for more than five minutes and will scale in if the CPU utilization of one of the nodes drops under 20% for more than ten minutes. There is a reverse proxy in front of the application. The systems administrator notices two of the nodes are often running over 80% for a long period of time, which is triggering the creation of the other two nodes; however, they are being created and terminated while the load in the first two remains over 50% all the time. Which of the following should the administrator configure to fix this issue?

  A. Disable DNS caching in the reverse proxy.

  B. Reduce the minimum node count to one.

  C. Disable TLS tickets.

  D. Reduce the scale-out rule to 50%.

  E. Increase the scale-in rule to 50%.

  Correct Answer: A

• Question 79:

  Over the last couple of years, the growth of a company has required a more complex DNS and DHCP environment. Which of the following should a systems administration team implement as an appropriate solution to simplify management?

  A. IPAM

  B. DoH

  C. VLAN

  D. SDN

  Correct Answer: A

  The best solution to simplify management of a more complex DNS and DHCP environment for a company that has grown over the last couple of years is IPAM (IP address management). IPAM is a tool or service that allows centralized

  management and automation of DNS and DHCP functions, such as IP address allocation, reservation, release, or renewal, as well as domain name registration or resolution. IPAM can also provide monitoring, auditing, reporting, and security

  features for DNS and DHCP resources.
