CompTIA Cloud+ CV0-003 Exam Questions and Answers PDF

A virtual extensible local area network (VXLAN) is a type of network virtualization technology that creates logical networks or segments that span across multiple physical networks or locations. Moving the web and database servers onto the same VXLAN can help resolve the network throughput issues following a deployment, as it can reduce the network traffic between the database and the web servers by using a common virtual network identifier (VNI) and encapsulating the traffic within UDP packets. Moving the web and database servers onto the same VXLAN can also improve performance and security, as it can provide higher scalability, isolation, and encryption for the network traffic.

Permissions are rules or settings that determine what actions users can perform on files or resources in a system or service. Permissions can help control and restrict access to files or resources based on various criteria, such as user identity, role, group, or ownership. Defining and configuring the proper permissions for the file-sharing service is the best step for the administrator to take next after discovering that sales group members can access the financial application due to being part of the finance group and having write access to all files in the file-sharing service. Defining and configuring the proper permissions can prevent unauthorized or accidental access or modification of files or resources by limiting or granting access based on specific criteria.

Passthrough is a type of GPU configuration that allows a VM to directly access a physical GPU on the host system without any virtualization layer or sharing mechanism. Passthrough can provide optimal performance and compatibility for GPU-intensive applications, such as rendering or gaming, as it eliminates any overhead or contention caused by virtualization or sharing. Passthrough is also suitable for servers with limited CPU resources, as it reduces the CPU load and offloads the graphics processing to the GPU. Passthrough is the most optimal GPU configuration for virtualizing a new server with GPUs for render farms. References: CompTIA Cloud+ Certification Exam Objectives, page 11, section 1.6
