Domain Node Server, it stores files for websites so browsers can download them.
Dynamic Network Service, it assigns IP addresses to devices when they connect.
--answer--
Domain Name System, it translates human-readable domain names into IP addresses.

The TLD Server
The Root Server
--answer--
The Recursive Resolver
--question--

What does TCP do that the Internet Protocol (IP) alone does not?
--distractors--
It routes packets from source to destination using IP addresses.
It encrypts data before sending it over the network.
It assigns domain names to IP addresses.
--answer--
It ensures reliable, ordered delivery by numbering segments and requesting retransmission of lost packets.

Which HTTP method should be used to partially update an existing resource on a server?
--distractors--

Which HTTP status code indicates that a requested resource has been permanently moved to a new URL?
--distractors--
302
304
404
--answer--
301
--question--
--text--
What is the difference between a 401 Unauthorized and a 403 Forbidden response?
--distractors--
401 means the server crashed while 403 means the resource does not exist.
401 is a client error while 403 is a server error.
401 means the resource was permanently moved while 403 means it was temporarily moved.
--answer--
401 means credentials are required while 403 means the client has valid credentials but lacks permission for the resource.
--question--
--text--
Which part of an HTTP request contains the method, path, and HTTP version?
--distractors--
The response body
The request body
The request headers
--answer--
The request line
--question--
--text--
What does the 304 Not Modified status code tell the client?
--distractors--
The resource was deleted from the server.
The request was malformed and should be resent.
The server is temporarily unavailable.
--answer--
The resource has not changed since the last request, so the client should use its cached version.
--question--
--text--
In the HTTP request-response cycle, what happens immediately after the server processes the request?
--distractors--
The client sends a second request to confirm receipt.
The DNS resolver caches the response.
The client initiates a new TCP connection.
--answer--
The server prepares a response with a status code, headers, and an optional body.

--answer--

Why must server-side validation always be performed even when client-side validation is already in place?
--distractors--
Client-side validation is not supported in modern browsers.
Server-side validation is only needed for file uploads.
Client-side validation runs faster than server-side validation.
--answer--
Client-side validation can be bypassed, so server-side validation is required for security.

--distractors--

Khronos Group
--answer--
WHATWG
--question--
--text--
What is TC39, and what is its role in the web standards ecosystem?
--distractors--
A W3C working group responsible for CSS specifications.
A browser vendor consortium that decides which features ship in Chrome.
A Khronos Group committee that manages WebGL standards.
--answer--
A technical committee within ECMA International that advances JavaScript language features through a five-stage proposal process.
--question--
--text--
During which stage of the web standards lifecycle does a feature get stress-tested through open discussion, use-case gathering, and competing design approaches?
--distractors--
Specification testing
Finalization testing
Interoperability testing
--answer--
Incubation
--question--
--text--
What is the purpose of the W3C Web Platform Tests suite during the standards process?
--distractors--
To rank browser performance for marketing purposes.
To replace the need for a written specification.
To allow developers to submit new feature proposals.
--answer--
To verify that every browser implements a feature identically.
--question--
--text--
Which principle of web standards ensures that a page built to specification behaves the same way in Chrome, Firefox, and Safari?
--distractors--
Backwards compatibility
Progressive enhancement
Openness
--answer--
Interoperability
--question--
--text--
What does the principle of progressive enhancement require when designing a web feature?
--distractors--
The feature must only target the latest browser versions.
The feature must be implemented in JavaScript before CSS or HTML.
The feature must be finalized before any browser can implement it.
--answer--
The feature must work for everyone first, then improve for users with more capable browsers or devices.
--question--
--text--
Why does the web maintain near-absolute backwards compatibility when introducing new standards?
--distractors--
New standards always replace old ones, so older pages are automatically updated.
Browser vendors are legally required to support every page ever published.
Old pages are archived and served from a separate network.
--answer--
So that pages built years ago continue to work correctly in modern browsers.
