Question 1

Unlike ftp, http does not have a secure version.

Accepted Answer

HTTP does have a secure version called HTTPS (HTTP Secure) which uses SSL/TLS encryption to ensure secure communication between the web server and client.

Question 2

smtp is the protocol used between browsers and Web servers.

Accepted Answer

SMTP (Simple Mail Transfer Protocol) is a protocol used for sending and receiving email messages, not between browsers and web servers. HTTP (Hypertext Transfer Protocol) is the protocol used between web browsers and web servers.

Question 3

Assignment of both public and private IP addresses is controlled by ICANN.

Accepted Answer

ICANN is responsible for coordinating the assignment of unique identifiers on the Internet, such as domain names and IP addresses, but the assignment of public and private IP addresses is primarily controlled by the Internet Assigned Numbers Authority (IANA) and the Regional Internet Registries (RIRs).

Question 4

Web servers run on a server-tier computer and manage traffic by sending and receiving Web pages to and from clients.

Accepted Answer

This statement is true. Web servers handle incoming requests from clients, retrieve the requested web page from the server’s files, and send it back to the client’s browser.

Question 5

ftp is the protocol used mainly for email transmissions.

Accepted Answer

FTP (File Transfer Protocol) is a protocol used for transferring files between computers on a network. It is not mainly used for email transmissions, but instead for transferring files such as documents, images, and videos. Email transmissions typically use protocols like SMTP (Simple Mail Transfer Protocol) and POP3 (Post Office Protocol).

Question 6

The ________ tier of the three-tier architecture consists of computers, phones, and other mobile devices that have browsers that request and process Web pages.

Accepted Answer

The user tier is the front-end of the three-tier architecture and consists of the devices that users interact with to request and access web pages. These devices include computers, phones, and other mobile devices with browsers.

Question 7

Which of the following refers to the three tiers in the three-tier architecture?

Accepted Answer

The three tiers in the three-tier architecture refer to the user interface tier (client-side), application server tier (server-side), and database server tier (data-side). These tiers are responsible for different parts of the application, with the user interface tier interacting with the user, the application server tier handling the logic and processing, and the database server tier managing data storage and retrieval. None of the other options listed refer to the three tiers in the three-tier architecture.

Question 8

https is the secure version of http.

Accepted Answer

HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, where the communication between the client (browser or app) and the server is encrypted.

Question 9

________ are programs that run on a server-tier computer and manage traffic by sending and receiving Web pages to and from clients.

Accepted Answer

Web servers are designed to manage traffic by sending and receiving web pages to and from clients. They are specifically designed to handle HTTP requests and responses, and can also handle other protocols like FTP, SMTP, and more. Web browsers, on the other hand, are client-side programs used to view and access web pages. Server farms and server racks are collections of server computers used to provide high availability and performance for web services, but they do not directly manage traffic.
