1. HTTP status codes that begin with 4xx, like 404, indicate:

Answers

·        Redirections

·        Client-side errors

·        Server-side errors

·        Nowhere; these codes are successful

Explanation: Responses from clients that have HTTP status codes that begin with 4xx, such as 404, are considered to be errors. These error codes are what the server sends back to the client when it determines that the client—typically a web browser or user agent—appears to have made a mistake in the request that was sent.

2. HTTP status codes that begin with 5xx, like 501, indicate:

Answers

·        Server-side errors

·        Client-side errors

·        Redirections

·        Nowhere; these codes are successful

Explanation: Status codes in the HTTP protocol that begin with 5xx, such as 501, indicate that the server encountered an issue. These error codes are what the server sends back to the client when it cannot fulfill the request because it has run into some kind of problem or is unable to do so for some other reason.

3. What are tools that are built into browsers to help diagnose issues with the browsers?

Answers

·        Developer tools

·        Platform services

·        Database servers

·        HTTP web servers

4. What do HTTP status codes beginning with 2xx indicate?

Answers

·        Client-side errors

·        Redirection

·        Server-side errors

·        Successful request

Explanation: Responses to HTTP status codes beginning with 2xx indicate that they were successful. The customer is informed by these codes about whether or not their request was successfully received, interpreted, and accepted. As an instance, the well-known status code 200 OK indicates that the request was fulfilled successfully, but the status code 201 Created indicates that the request resulted in the development of a new resource.

5. Which of these leads to a 404 error?

Answers

·        You type in the human readable name for a site that no longer exists.

·        You type in the URL of a site instead of the human readable name (something ending with.com, .edu or any dot ending).

·        You type in a good address or readable name for a site, but the server holding the site is having problems.

·        You accidentally type in the wrong readable name, and you get to a different site than you wanted.

Explanation: When the server is unable to locate the resource that was requested, a 404 error is generated. Therefore, the server will reply with a 404 status code whenever a client requests a page or resource that is not currently stored on the server. It's the equivalent of the server stating, "I couldn't find what you're looking for."

6. Which of the following are popular paid-for options for setting up IM services for your organization? Select all that apply.

7. What type of DNS record is used for email servers?

Answers

·        AAAA

·        A

·        MX

·        CNAME

Explanation: The Mail Exchange (MX) record is the part of the Domain Name System (DNS) that stores information about email servers. The mail servers that are accountable for accepting email on behalf of a domain are pointed out by its MX records. When someone sends an email to an address that is linked with a certain domain, the email server that is doing the sending does a search through the MX records for that domain to identify where the email should be sent. The MX record includes details on the hostname of the mail server as well as its priority, which indicates the sequence in which several mail servers should be checked for delivery.

20. Which printing language is device-dependent?

Answers

·        Ruby

·        A: PCL

·        PS

·        B: Python

Explanation: Device-dependent printing languages are languages that cannot be printed on any other kind or brand of printer except the one they were designed for. Printer Command Language (PCL), often known as Hewlett-Packard (HP) printer language, is an illustration of a device-dependent printing language. PCL is connected with HP printers.

Page description language, or PCL, is a programming language that is used to handle different parts of the printing process. These features include formatting, the selection of fonts, and images. However, it is only compatible with printers manufactured by HP, and it is possible that it will not work with printers manufactured by other companies.

Device-independent printing languages, on the other hand, like PostScript, are intended to be more general in their functionality and to operate with a variety of various printer brands and models. For example, PostScript is a language for describing pages that was created by Adobe and is widely supported by a variety of printers.

·        On a web server

Explanation: Information about customers, such as articles from newspapers or magazines, videos, vast volumes of text, photographs, or audio files, is often kept in a database or another kind of file storage system that is connected with online services. The characteristics of the data and the needs of the online service should guide the selection of the storage method.

23. HTTP status codes are codes or numbers that indicate some sort of error or info message that occurred when trying to access a web resource. When an HTTP request is successful, what number does the HTTP status code start with?

Answers

·        2xx

·        4xx

·        6xx

Explanation: The HTTP status code normally begins with the number 2 whenever a request sent over HTTP is processed successfully. In particular, answers that are considered successful are denoted by the HTTP status codes that begin with the 2xx prefix. The following is the success status code that occurs most frequently:

This status code indicates that the server has successfully returned the requested resource, indicating that the request was completed successfully.Therefore, if the status code you received begins with the number 2, it indicates that the HTTP request was processed successfully.

24. Which email protocol is capable of sending emails?

Answers

·        POP3

·        MX DNS

·        SMTP

26. Which of the following security protocols is used to format and transfer web content.

Answers

·        C: Hypertext Transfer Protocol Secure (HTTPS)

·        The Transport Layer Security protocol (TLS)

·        The Secure Socket Layer protocol (SSL)

·        The SMB protocol (Samba)

Explanation: The Hypertext transport Protocol Secure (HTTPS) is the name of the security protocol that is used during the formatting and transport of material on the web. The Hypertext Transfer system (HTTP), which is the de facto standard for moving data across the web, is not in and of itself a secure system. HTTPS is the secure version of HTTP, and it utilizes encryption to protect the confidentiality and integrity of the data being exchanged between a web server and a client (usually a web browser). HTTP is the hypertext transfer protocol. HTTPS is the secure version of HTTP.

To encrypt the transmission and secure sensitive information such as login passwords, personal data, and payment information, HTTPS makes use of the SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols. It is frequently used for safeguarding sensitive conversations and transactions that take place over the internet.

32. When browsing a website, what is a quick way to know that the site is secure?

Answers

·        The URL begins with tls

·        The URL begins with http

·        The URL begins with https

·        The website has a banner that says it’s secure

Explanation: These symbols indicate that the connection between your browser and the website is encrypted, which assists in preventing unwanted access to sensitive information such as login passwords, personal data, and payment details.

In addition, when a secure connection is present, some web browsers will either highlight the website's URL in the address bar or show the website's name in green letters. On the other hand, if a website is not secure, your web browser may warn you or indicate that the connection is not private and continue to show the information.

It is important to keep in mind that although while HTTPS denotes a secure connection, this does not always ensure that the material on the website is legitimate or trustworthy. Other trust indications, such as a valid SSL/TLS certificate issued by a respected certificate authority and third-party trust seals, if relevant, are good things to check for in this context.

33. Which statements are true about HTTPS and security protocols? Select all that apply.

Answers

·        HTTPS can be secured with Transport Layer Security protocol (TLS)

·        C: HTTPS is a secure version of the Hypertext Transfer Protocol.
