In order to create a new IP address in Linux, where would you store the new configuration?

Named.conf
Rc.local
Httpd.conf

Correct Answer(s)

A. Rc.local
A. Httpd.conf

Explanation

The correct answer is rc.local, httpd.conf. In Linux, the rc.local file is commonly used to store system startup commands and scripts. By adding the necessary configuration for the new IP address in the rc.local file, it will be applied during the system startup process. On the other hand, httpd.conf is the configuration file for the Apache HTTP server, which is responsible for handling web server settings. While it may not be the most appropriate location for storing IP address configurations, it could potentially be used for specific cases involving web server IP addresses.

Stored information about a previous visit to a Web Site is called _______ information.

HTTP
State information

Correct Answer

A. State information

Explanation

State information refers to the stored information about a previous visit to a website. This can include data such as user preferences, login credentials, or session details. State information allows websites to personalize the user experience and remember specific information about the user's interactions. HTTP, on the other hand, is a protocol used for communication between web servers and clients, and is not directly related to storing information about previous visits.

Which of the following is not a tool for maintaining state information with pHP?

Hidden form fields
Query strings
Functions
Cookies

Correct Answer

A. Functions

Explanation

Functions in PHP are not specifically designed for maintaining state information. They are used to organize and reuse code, perform specific tasks, and return values. State information is typically managed using tools like hidden form fields, query strings, and cookies. Hidden form fields allow data to be passed between web pages without displaying it to the user. Query strings can store data in the URL itself. Cookies are used to store data on the user's computer.

One way to preserve information following a user's visit to a Web page is to append a _______ at the end of a URL.

Query string
Function
Auto-global
Identifier

Correct Answer

A. Query string

Explanation

A query string can be appended at the end of a URL to preserve information following a user's visit to a web page. It is a part of the URL that contains data in the form of key-value pairs. This data can be used to pass information to the server or to dynamically generate content on the web page. By including a query string in the URL, the information can be retained and accessed by the server or other scripts on the page.
