David wants to install a proxy server that can reduce the organization’s upstream bandwidth usage, reduce cost, and improve the network performance. Which of these could serve his purpose?
Explanation
Answer: D - To reduce upstream bandwidth, lower cost, and improve performance, David should use a caching proxy server.
A caching proxy server accelerates service requests by retrieving content saved from a previous request. Caching proxies keep local copies of frequently-requested resources, allowing large organizations to significantly reduce their upstream bandwidth usage and cost, while significantly increasing performance. A content-filtering web proxy server provides administrative control over the content that may be relayed through the proxy.
