1Which HTTP method is typically used to RETRIEVE a resource without modifying it?

A.POST

B.GET

C.PUT

D.DELETE

Explanation: GET is for safe, idempotent retrieval — should not modify server state. POST creates resources or submits data. PUT updates (replaces) a resource at a known URL. DELETE removes. PATCH is partial update. HEAD is GET without the response body. GET requests can be cached, bookmarked, and shared as URLs.

2Which HTTP status code means 'Created'?

A.200

B.201

C.204

D.301

Explanation: 201 Created is returned when a resource has been successfully created (typically by POST or PUT). 200 OK = generic success. 204 No Content = success with no response body (often for DELETE). 301 = permanent redirect. The Location header in a 201 response often points to the new resource's URL.

3What does HTTP status 401 indicate?

A.Forbidden — authenticated but no permission

B.Unauthorized — authentication required

C.Not Found

D.Internal Server Error

Explanation: 401 Unauthorized: the request lacks valid authentication credentials. (Misleading name — it's really 'Unauthenticated'.) 403 Forbidden: authenticated but not allowed. 404 Not Found: resource doesn't exist. 500 Server Error. The 401 response includes a WWW-Authenticate header indicating how to authenticate.

4What is the purpose of the Content-Type header?

A.To specify the cookie

B.To indicate the media type of the body (e.g., application/json, text/html)

C.To set the response timeout

D.To control caching

Explanation: Content-Type tells the recipient how to interpret the body. Examples: application/json, application/x-www-form-urlencoded, multipart/form-data, text/html, image/png. For JSON APIs, both client (sending) and server (receiving) must set/parse it correctly. Charset is often appended: text/html; charset=utf-8.

5What does CORS stand for and what does it do?

A.Cross-Origin Resource Sharing — controls whether a browser allows JS on one origin to access resources from another

B.Centralized Object Routing System

C.Common Object Request Standard

D.Cross-Origin Request Signature

Explanation: CORS = Cross-Origin Resource Sharing. The browser enforces the same-origin policy by default; CORS headers (Access-Control-Allow-Origin, etc.) on the server tell the browser which other origins may access the resource. Misconfigured CORS is a common source of frustrating API errors during development.

6What is REST?

A.A specific Python framework

B.An architectural style using HTTP verbs and resource-based URLs (often with JSON) for web APIs

C.A database query language

D.A binary protocol

Explanation: REST (Representational State Transfer) = architectural style: resources identified by URIs, manipulated by standard HTTP methods (GET, POST, PUT, DELETE), stateless, with standard status codes. Often uses JSON. Benefits: simple, cacheable, leverages HTTP. Alternatives: GraphQL, gRPC, SOAP.

7What is a query string?

A.The body of a POST request

B.Key-value pairs appended to a URL after a '?' (e.g., ?q=python&page=2)

C.A SQL query

D.A regex pattern

Explanation: Query strings carry parameters in the URL: /search?q=python&page=2. Multiple params separated by '&'. Special characters must be URL-encoded (%20 for space, etc.). Used primarily with GET requests. In Flask: request.args.get('q'). In Django: request.GET.get('q').

8What is URL encoding?

A.Encrypting URLs

B.Replacing reserved or unsafe characters in URLs with %XX hex codes (e.g., space → %20)

C.Compressing URLs

D.Adding HTTPS to URLs

Explanation: URL encoding (percent-encoding, RFC 3986) escapes characters that would otherwise have special meaning in URLs. Space → %20 (or '+' in form-encoded bodies), '&' → %26, '/' → %2F. Python: urllib.parse.quote(). Always encode user input before embedding in URLs to prevent breakage and security issues.

9Which semantic HTML5 tag is appropriate for the main heading area of a page?

A.<header>

B.<head>

C.<top>

D.<heading>

Explanation: <header> is a semantic tag for introductory content, often containing the site logo, navigation, and main heading. <head> (in <html>) holds metadata, not visible content. <heading> isn't a real tag (use <h1>-<h6>). Other semantic tags: <nav>, <main>, <article>, <section>, <footer>, <aside>.

10Which CSS property creates flexible layout containers in modern web design?

A.display: flex (or display: grid)

B.position: absolute

C.float: left

D.table-layout: fixed

Explanation: display: flex (Flexbox) creates a 1D flexible container — child elements distribute along a main axis. display: grid creates a 2D layout. Both replaced older techniques (floats, table layouts) for most page layout. Common flex props: flex-direction, justify-content, align-items, gap.

About the PCEW Exam

Frequently Asked Questions

What is the PCEW certification?

The OpenEDG PCEW (Certified Entry-Level Web Developer with Python) is an entry-level certification from the Python Institute / OpenEDG that validates foundational web development skills using Python. It covers HTTP, HTML/CSS, Flask, Django, FastAPI, databases, deployment, and web security.

How many questions are on the PCEW exam?

The PCEW exam has approximately 30 questions to be completed in 40 minutes. Question types include single-select, multiple-select, and input-based items. The passing score is 70%. Results are provided immediately upon completion through the OpenEDG Testing Service.

Are there prerequisites for the PCEW exam?

There are no formal prerequisites for the PCEW exam, but basic Python knowledge (PCEP-level) is strongly recommended. Familiarity with HTML, CSS, and basic web concepts (HTTP, browsers) is helpful but you can learn these alongside the framework material.

Does PCEW cover Flask, Django, or both?

The PCEW covers BOTH Flask and Django at an introductory level, plus a brief intro to FastAPI. Flask is covered for micro-framework patterns (routes, Jinja2, sessions, blueprints). Django is covered for the full MTV pattern, ORM, admin, and forms. Both are commonly used in Python web jobs, so understanding both is valuable.

How should I prepare for the PCEW exam?

Plan for 40-60 hours of study over 6-8 weeks. Build a small Flask app (todo list with SQLite), a Django blog (with admin and forms), and a FastAPI REST endpoint. Study HTTP basics, Jinja2 syntax, Django ORM querysets, and web security. Complete 100+ practice questions and aim for 80%+ before scheduling.

What jobs can I get with PCEW certification?

PCEW demonstrates entry-level Python web development skills suitable for: Junior Python Developer, Backend Web Developer, Full-Stack Developer (with frontend skills), Django Developer, Flask Developer, and API Developer. It pairs well with PCEP/PCAP and frontend frameworks (React, Vue) for full-stack roles.
