💼 Career

Understanding domain setup is useful for roles in web development, IT support, and digital marketing.

1

Create a list of domain registrars

Create a list called domain_registrars containing these exact names: 'GoDaddy', 'Namecheap', 'Google Domains', 'Bluehost'.

No-Code

# Create a list called domain_registrars with the given names
# Your code here

Hint

Use square brackets to create a list and include all names as strings separated by commas.

2

Add your custom domain name

Create a variable called custom_domain and set it to the string 'mywebsite.com'.

No-Code

domain_registrars = ['GoDaddy', 'Namecheap', 'Google Domains', 'Bluehost']
# Create a variable custom_domain with the value 'mywebsite.com'
# Your code here

Hint

Assign the domain name as a string to the variable custom_domain.

3

List the DNS record types needed

Create a list called dns_records containing these exact strings: 'A', 'CNAME', 'TXT'.

No-Code

domain_registrars = ['GoDaddy', 'Namecheap', 'Google Domains', 'Bluehost']
custom_domain = 'mywebsite.com'
# Create a list dns_records with 'A', 'CNAME', and 'TXT'
# Your code here

Hint

Use a list to hold the DNS record types as strings.

4

Describe the final verification step

Create a variable called final_step and set it to the string 'Verify domain ownership through your hosting provider'.

No-Code

domain_registrars = ['GoDaddy', 'Namecheap', 'Google Domains', 'Bluehost']
custom_domain = 'mywebsite.com'
dns_records = ['A', 'CNAME', 'TXT']
# Create a variable final_step with the verification instruction
# Your code here

Hint

Assign the exact verification instruction as a string to final_step.

Practice

1. What is the main purpose of setting up a custom domain for a website?

easy

A. To create multiple websites under one address

B. To increase the website's loading speed automatically

C. To avoid paying for web hosting services

D. To use your own unique website address instead of a generic one

Solution

1. Step 1: Understand what a custom domain is

   A custom domain is a unique website address you buy and use instead of a default or generic address.

2. Step 2: Identify the main benefit

   Using your own domain makes your website look professional and easy to remember.

3. Final Answer:

   To use your own unique website address instead of a generic one -> Option D

4. Quick Check:

   Custom domain = unique website address [OK]

Hint: Custom domain means your own website name, not a default one [OK]

Common Mistakes:

• Thinking it speeds up the website automatically
• Believing it removes hosting fees
• Confusing it with creating multiple sites

2. Which of the following is a necessary step when setting up a custom domain?

easy

A. Buying the domain from a domain registrar

B. Installing a web browser

C. Creating a social media account

D. Writing website content first

Solution

1. Step 1: Identify the first step in custom domain setup

   You must first buy the domain name from a domain registrar to own it.

2. Step 2: Recognize unrelated options

   Installing a browser, social media, or writing content are not required to set up the domain itself.

3. Final Answer:

   Buying the domain from a domain registrar -> Option A

4. Quick Check:

   Domain setup starts with buying domain [OK]

Hint: First buy your domain before any other setup step [OK]

Common Mistakes:

• Confusing domain purchase with website content creation
• Thinking browser installation is needed
• Assuming social media accounts are required

3. After buying a domain, which DNS record is commonly updated to point the domain to your website hosting?

medium

A. A record

B. TXT record

C. MX record

D. CNAME record

Solution

1. Step 1: Understand DNS records for domain setup

   The A record links your domain to the IP address of your website hosting server.

2. Step 2: Differentiate DNS record types

   MX is for email, TXT for verification, CNAME for aliasing subdomains, so A record is correct for main website pointing.

3. Final Answer:

   A record -> Option A

4. Quick Check:

   Website IP linked via A record [OK]

Hint: A record points domain to website IP address [OK]

Common Mistakes:

• Using MX record which is for email
• Confusing CNAME with main domain pointing
• Thinking TXT record controls website address

4. You updated your domain's DNS A record but your website still shows the old page. What is the most likely reason?

medium

A. You forgot to buy the domain

B. Your website hosting is offline permanently

C. DNS changes take time to update (propagation delay)

D. You need to clear your website content manually

Solution

1. Step 1: Understand DNS propagation

   DNS changes can take several hours to days to spread worldwide, causing old pages to appear temporarily.

2. Step 2: Evaluate other options

   Domain must be bought before updating DNS, hosting offline would cause errors, and clearing content manually is unrelated to DNS.

3. Final Answer:

   DNS changes take time to update (propagation delay) -> Option C

4. Quick Check:

   DNS propagation delay causes old page display [OK]

Hint: Wait for DNS propagation after changes [OK]

Common Mistakes:

• Assuming immediate DNS update
• Forgetting domain purchase step
• Blaming hosting without checking status

5. You want to use a custom domain for your website but also keep your email with the same domain. Which DNS records must you configure correctly?

hard

A. CNAME record for website and TXT record for email

B. A record for website and MX record for email

C. Only MX record for website and email

D. Only A record for both website and email

Solution

1. Step 1: Identify DNS records roles

   A record points your domain to your website's server IP, while MX record directs email to your mail server.

2. Step 2: Understand combined setup

   To use the same domain for website and email, both A and MX records must be set correctly.

3. Final Answer:

   A record for website and MX record for email -> Option B

4. Quick Check:

   Website = A record, Email = MX record [OK]

Hint: Use A for website, MX for email on same domain [OK]

Common Mistakes:

• Using only A record for email
• Confusing MX with website pointing
• Using CNAME or TXT incorrectly for email routing
