CompTIA CV0-003 Actual Questions

Checking the GPU (Graphics Processing Unit) is the first thing that the VDI administrator should do to optimize the performance of the VDI infrastructure for rendering tasks. GPU is a specialized hardware device that accelerates graphics processing and rendering. GPU can improve the user experience and performance of VDI applications that require intensive graphics processing, such as drafting, gaming, video editing, etc.

Ping is the command that will help the administrator understand the possible latency issues between different network service providers and link load balancing for bandwidth aggregation. Ping is a network utility that sends packets of data to a specific IP address or hostname and measures the time it takes for them to be sent back (round-trip time). Ping can help to test connectivity, availability, and latency of network devices or systems. Ping can help to understand latency issues by comparing the round-trip times between different network service providers and link load balancing devices, and identifying any delays or variations in response times.

Software as a service (SaaS) is a type of cloud service model that provides software applications over the Internet that are hosted and managed by a cloud service provider. Directory service federation is a type of authentication mechanism that allows users to access multiple systems or applications across different domains or organizations with a single login credential. Using a SaaS service with a directory service federation can help migrate an internal file server to the cloud and use a web-based interface to access and manage the files, as it can eliminate the need for maintaining an on-premises file server and enable seamless and secure access to cloud-based files using the same corporate logins.

An application programming interface (API) is a set of rules or protocols that defines how different systems or applications can communicate or interact with each other. An API version is a specific iteration or release of an API that may have different features or functionalities than previous or subsequent versions. API version incompatibility is the most likely cause of the script failure when switching hosting companies and using the same script that was previously used to deploy VMs in the new cloud, as it can result in errors or failures when trying to execute commands or functions that are not supported or recognized by the new cloud provider’s API version. The issue can be resolved by updating or modifying the script to match the new cloud provider’s API version. References: CompTIA Cloud+ Certification Exam Objectives, page 13, section 2.5
