Question 3
lf you need to accelerate a certain domain name (such as abc.com) via Alibaba Cloud Content Delivery Network (CDN), you must add it to "CDN Domain Name List" in the CDN service. After added successfully, you will get a CNAME address A. Next, you need to modify domain name resolution and direct the domain name (such as abc.com) to CNAME address A. Which of the following is a NOT correct description of modifying domain name resolution? (Single answer)
The DNS service provider used by the domain name (such as abc.com) must support intelligent resolution.
The DNS service provider used by the domain name (such as abc.com) can be companies other than Alibaba Cloud.
If your domain name (such as abc.com) is transferred to Alibaba Cloud in advance, and managed by the same Alibaba Cloud account, you can perform one-step resolution modification.
The CNAME address allocated to the domain name (such as abc.com) will point to an IP address. This IP address resolving mechanism is intelligently managed by Alibaba Cloud CDN system.
