An administrator needs to increase the access speed for client files that are stored on...

To improveaccess speed for client filesstored on a file server, the administrator shouldEnable Network Cachewithin the client’sVirus and Spyware Protection policy. This setting allows client machines to cache scanned files from the network, thus reducing redundant scans and increasing read speed from the server.

How Network Cache Enhances Read Speed:

When Network Cache is enabled, previously scanned files are cached, allowing subsequent access without re-scanning, which decreases latency and improves access speed.

Why Other Options Are Less Effective:

Adding the server to a trusted host group(Option B) does not directly impact file read speeds.

Creating a firewall allow rule(Option C) allows connectivity but does not affect the speed of file access.

Enabling download randomization(Option D) only staggers update downloads and does not relate to read speeds from a file server.
