AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 28

A company's application is hosted by an internet provider at app.example.com. The company wants to access the application by using www.company.com, which the company owns and manages with Amazon Route 53.
Which Route 53 record should be created to address this?

Answer options

• A. A record
• B. Alias record
• C. CNAME record
• D. Pointer (PTR) record

Correct answer: C

Explanation

The correct answer is C, as a CNAME record allows the domain www.company.com to point to app.example.com effectively. An A record is not suitable here because it requires an IP address, while an Alias record is unnecessary for this specific case, and a Pointer (PTR) record is used for reverse DNS lookups, which is irrelevant for this scenario.
