Understanding Domain Registration Ownership

When you register a domain using AWS Route 53, who is considered the official owner of the domain?

A Amazon Web Services owns all domains registered through Route 53.

B The person or organization listed as the registrant in the domain's WHOIS information.

C The AWS account that registered the domain is the official owner.

D The domain registrar company owns the domain, not the registrant.

💡 Hint

Think about who appears in the public WHOIS database as the domain holder.

The official owner of a domain is the registrant listed in the WHOIS database, which is the person or organization that registered the domain. AWS acts as the registrar but does not own the domain.

Domain Availability Check Behavior

You want to register a new domain using AWS Route 53. What happens if you try to register a domain name that is already taken?

A Route 53 automatically registers the domain for you anyway.

B Route 53 registers the domain but with a different extension automatically.

C Route 53 queues your request and registers the domain if it becomes available later.

D Route 53 shows an error that the domain is unavailable and prevents registration.

💡 Hint

Consider what happens when a domain is already owned by someone else.

If a domain is already registered by someone else, Route 53 will not allow you to register it again. It will show that the domain is unavailable.

❓ Configuration

Configuring Domain Auto-Renewal in Route 53

You want to ensure your domain registered in AWS Route 53 never expires accidentally. Which configuration option should you enable?

A Set a CloudWatch alarm to notify you before expiration.

B Manually renew the domain every year before expiration.

C Enable the 'Auto Renew' option in the domain registration settings.

D Transfer the domain to another registrar with longer expiration.

💡 Hint

Look for a setting that automatically renews the domain without manual intervention.

Enabling 'Auto Renew' in Route 53 ensures the domain registration is automatically renewed before expiration, preventing accidental loss.

❓ security

Protecting Domain Transfer with Authorization Code

To transfer a domain from AWS Route 53 to another registrar, what security measure must you provide to the new registrar?

A The domain's authorization code (also called EPP code).

B The AWS account password used to register the domain.

C The domain's DNS records exported as a file.

D The billing information used for the domain registration.

💡 Hint

This code acts like a password specifically for domain transfers.

The authorization code (EPP code) is a unique code required to transfer a domain to another registrar. It prevents unauthorized transfers.

Best Practice for Domain Privacy Protection

When registering a domain in AWS Route 53, what is the best practice to protect your personal contact information from public WHOIS records?

A Enable WHOIS privacy protection offered by Route 53 during registration.

B Register the domain using a public email address only.

C Do not provide any contact information during registration.

D Use a fake name and address in the registration details.

💡 Hint

Think about a service that hides your personal details from public view.

Enabling WHOIS privacy protection replaces your personal contact details with proxy information in the public WHOIS database, protecting your privacy.
