Desktop Virtualization

Correct Answer: Enable RemoteFX

The best feature to improve graphics experience for a remote user's virtual desktop would be 'Enable RemoteFX'. RemoteFX is a feature in Windows Server that allows for hardware-accelerated graphics rendering, enabling the delivery of a full-fidelity user interface to remote users. Enabling Terminal Services would not directly improve graphics performance as it chiefly focuses on handling multiple connections. Implementing Thin clients is more about budget saving and controlling resources centrally which doesn't directly boost graphics performance. Finally, 'Enable PXE Boot' relates to network booting, which has no direct impact on graphics performance.

Correct Answer: Place the virtual machines' virtual disks on SSDs

Placing the virtual machines' virtual disks on Solid-State Drives (SSDs) could potentially improve the performance of the virtual machines as SSDs have faster read/write speeds compared to traditional Hard Disk Drives (HDDs). This could significantly reduce the latency experienced by users. Meanwhile, decreasing the amount of RAM assigned to the virtual machines could actually degrade performance as it might lead to insufficient memory for applications to run smoothly. Migrating to a private cloud solution isn't necessarily a solution to slow responsiveness as it also depends on various factors like network bandwidth, latency, and the capabilities of the cloud provider. Lastly, implementing Layer 3 switching wouldn't necessarily improve virtual machine performance as it functions at the network layer to manage traffic by IP address rather than catering directly to system performance.

Correct Answer: Apply role-based access control (RBAC)

The best practice for implementing security in a virtual desktop environment is by applying role-based access control (RBAC). RBAC allows a company to manage the access to systems or network resources based on the roles of individual users within the company. This ensures that only the authorized people have access to specific resources. Enabling all users with admin privileges can lead to serious security risks as it grants all users full control over the system which is not advisable. Implementing Load Balancers is used to distribute network or application traffic across a number of servers but it does not provide any access control settings. Creating VLANs (Virtual Local Area Network) is a way to partition a physical network into smaller virtual networks but this also does not provide access control to the user.
