SOA-C02 Question 252
Select 3Your company has recently acquired a new domain, 'example.com', and plans to host its content on an Amazon S3 bucket configured as a static website. As a SysOps Administrator, you need to set up DNS routing for this domain using Amazon Route 53. Which of the following steps should you take to configure the Route 53 hosted zone and records to ensure that users accessing 'www.example.com' are routed to the static website hosted in the S3 bucket?
- A
Create a hosted zone for 'example.com' in Route 53.
- B
Create an A record in the Route 53 hosted zone with the alias set to the static website endpoint of the S3 bucket.
- C
Create a CNAME record in the Route 53 hosted zone pointing 'www.example.com' to the S3 bucket's static website endpoint.
- D
Enable Route 53 health checks for the hosted zone to monitor the S3 bucket's availability.
- E
Update the name servers for 'example.com' at the domain registrar to use the Route 53 name servers.
Show answer and explanation
Correct answers: A, B, E
Explanation
To route traffic to an S3 static website using Route 53, you need to create a hosted zone for the domain, configure an A record with an alias to point to the S3 bucket's website endpoint, and update the domain registrar's name servers to Route 53. CNAME records are not suitable for root domains, and health checks are optional unless advanced routing configurations are required.
- A. Correct.
Correct. A hosted zone must be created in Route 53 to manage DNS for 'example.com'. This hosted zone serves as the starting point for configuring DNS records.
- B. Correct.
Correct. An A record with an alias to the S3 static website endpoint is required to route traffic to the S3 bucket. Route 53 supports alias records for AWS resources like S3 buckets.
- C. Incorrect.
Incorrect. CNAME records cannot be used at the root domain level (e.g., 'www.example.com') when alias records are available. An A record with an alias is more suitable for this use case.
- D. Incorrect.
Incorrect. While health checks can be used for advanced monitoring and routing purposes, they are not required for this scenario where the goal is simple routing to a static website.
- E. Correct.
Correct. The domain registrar must be updated with the Route 53 name servers to ensure that DNS queries for 'example.com' are directed to Route 53.
