All CV0-003 Test Inside CompTIA Questions

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.

The best option to reduce the latency issues for the marketing team that is primarily based in Europe when retrieving the marketing materials that are hosted on a public IaaS service is to integrate a CDN (content delivery network) solution to distribute web content globally. A CDN is a network of geographically distributed servers that cache and deliver web content to users based on their proximity and network conditions. A CDN can improve the performance and availability of web content by reducing the distance and hops between the users and the servers, as well as offloading the traffic from the origin server.

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. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 3.0 Maintenance, Objective 3.3 Given a scenario, analyze system performance using standard tools.

The best option to implement a secure connection between two different locations is IPSec (Internet Protocol Security). IPSec is a protocol suite that provides security for IP-based communications over networks. IPSec can encrypt and authenticate the data packets between two endpoints, such as routers, firewalls, or VPN gateways. IPSec can also provide integrity, confidentiality, and replay protection for the data.
