CCNA: Cisco Certified Network Associate — Question 574

When is the PUT method used within HTTP?

Answer options

• A. to update a DNS server
• B. when a nonidempotent operation is needed
• C. to display a web site
• D. when a read-only operation is required

Correct answer: A

Explanation

The correct answer is A because the PUT method is specifically designed to update resources, such as a DNS server. The other options are incorrect as they either describe operations that do not involve updating resources (C and D) or refer to operations that should be idempotent, which is not applicable to the PUT method (B).
