Correct Answer: D
Section: Design Explanation
Web server can refer to either the hardware (the computer) or the software (the computer application) that helps to deliver content that can be accessed through the Internet. The most common use of Web servers is to host Web sites but there are other uses like data storage or for running enterprise applications. The primary function of a web server is to deliver web pages on the request to clients. This means delivery of HTML documents and any additional content that may be included by a document, such as images, style sheets and scripts.
A client, commonly a web browser or web crawler, initiates communication by making a request for a specific resource using HTTP and the server responds with the content of that resource or an error message if unable to do so. The resource is typically a real file on the server’s secondary memory, but this is not necessarily the case and depends on how the web server is implemented. While the primary function is to serve content, a full implementation of HTTP also includes ways of receiving content from clients. This feature is used for submitting web forms, including uploading of files.
Many generic web servers also support server-side scripting, e.g., Apache HTTP Server and PHP. This means that the behavior of the web server can be scripted in separate files, while the actual server software remains unchanged. Usually, this function is used to create HTML documents “on the- fly” as opposed to returning fixed documents. This is referred to as dynamic and static content respectively. The former is primarily used for retrieving and/or modifying information from databases. The latter is, however, typically much faster and more easily cached. Web servers are not always used for serving the world wide web. They can also be found embedded in devices such as printers, routers, webcams and serving only a local network. The web server may then be used as a part of a system for monitoring and/or administrating the device in question. This usually means that no additional software has to be installed on the client computer, since only a web browser is required (which now is included with most operating systems).

QUESTION 228
Which statement decribes the recommended deployment of DNS and DHCP servers in the Cisco Enterprise Architecture Model?
A. Place the DHCP and DNS servers in the Enterprise Campus Access layer and Enterprise branch.
B. Place the DHCP and DNS servers in the Enterprise Campus Server Farm layer and Enterprise branch.
C. Place the DHCP server in the Enterprise Campus Core layer and Remote Access/VPN module with the DNS server in the Internet Connectivity module.
D. Place the DHCP server in the Enterprise Campus Distribution layer with the DNS server in the Internet Connectivity module.
Correct Answer: B
Section: Architecture Explanation
For the Enterprise Campus, DHCP and internal DNS servers should be located in the Server Farm and they should be redundant. External DNS servers can be placed redundantly at the service provider facility and at the Enterprise branch.

QUESTION 230
Which two wireless attributes should be considered during a wireless site survey procedure? (Choose two.)
A. encryption
B. channel
C. authentication
D. power
E. SSID
Correct Answer: BD
Section: Wireless Explanation
RF Site Survey
Similar to performing an assessment for a wired network design, RF site surveys are done to determine design parameters for WLANs and customer requirements. RF site surveys help determine the coverage areas and check for RF interference. This helps determine the appropriate placement of wireless APs.
