Describe the Issue

The rest-api-and-web-services module in Back-End Development and APIs (v9) has no quiz block. Every other non-cert-project module in that superblock ends with a review and a quiz.

PR #69503 added a review-rest-api-and-web-services block to the rest-api-and-web-services module, giving the module the review page a quiz draws its questions from.

A new quiz-rest-api-and-web-services block should be created with 10 questions, covering the review page's topics:

• Web services and APIs
• The REST architecture
• HTTP status codes
• Monoliths vs. microservices

Six questions covering these topics already exist in quiz-introduction-to-express, where they do not belong. They are being removed from that quiz in #69505, so they are reproduced in full below and can be moved into the new quiz as-is:

### --question--

#### --text--

What is the relationship between an API and a web service?

#### --distractors--

Every API is a web service, but not every web service is an API.

---

APIs and web services are identical concepts.

---

Web services only work with REST, while APIs support multiple protocols.

#### --answer--

Every web service is an API, but not every API is a web service.

### --question--

#### --text--

Which HTTP header does a client use to tell the server which response format it wants?

#### --distractors--

`Content-Type`

---

`Authorization`

---

`X-Requested-With`

#### --answer--

`Accept`

### --question--

#### --text--

What does statelessness mean in a REST architecture?

#### --distractors--

The server stores the client's session data between requests.

---

The client keeps no state of its own across requests.

---

REST restricts all requests to read-only operations.

#### --answer--

The server stores no memory of previous requests.

### --question--

#### --text--

Which REST HTTP method is used to remove a resource?

#### --distractors--

`GET`

---

`POST`

---

`PUT`

#### --answer--

`DELETE`

### --question--

#### --text--

What is a key advantage of microservices over a monolith?

#### --distractors--

Simpler debugging and fewer network calls between services.

---

A single shared codebase that all teams contribute to.

---

Easier infrastructure management across all services.

#### --answer--

Faster development, better fault isolation, and the ability to use different languages per service.

### --question--

#### --text--

Which of the following is true about SOAP compared to REST?

#### --distractors--

SOAP uses JSON and is more flexible than REST, making it ideal for modern applications.

---

SOAP is the most widely used web service type today, having replaced REST in most systems.

---

SOAP supports multiple response formats, including plain text, JSON, and binary data.

#### --answer--

SOAP uses only XML and is common in enterprise systems that need stricter standards and security.

That leaves 4 more questions to write to reach 10.

Expected behavior

The rest-api-and-web-services module ends with a quiz page.

A quiz-rest-api-and-web-services block titled REST API and Web Services Quiz exists, scaffolded with pnpm run create-new-project, with:

• curriculum/challenges/english/blocks/quiz-rest-api-and-web-services/<ObjectId>.md, title: REST API and Web Services Quiz, challengeType: 8, containing one ## --quiz-- set of 10 questions, with the description line To pass the quiz, you must correctly answer at least 9 of the 10 questions below.
• curriculum/structure/blocks/quiz-rest-api-and-web-services.json with blockLabel: quiz, blockLayout: link, isUpcomingChange: false, and the challenge listed as REST API and Web Services Quiz
• an entry in the rest-api-and-web-services module in curriculum/structure/superblocks/back-end-development-and-apis-v9.json, last in the module
• a REST API and Web Services Quiz title and an intro entry in client/i18n/locales/english/intro.json, last in the module

The script's prompts should be answered with the Back-End Development and APIs certification, the back-end-development-and-apis chapter, the rest-api-and-web-services module, the Backend Development help category, a question count of 10, and a position placing the quiz last in the module.

Additional context

Per the quiz guide, quizzes are 10 or 20 questions with 4 options each, and all questions must come from the module's review page or its workshops.
