Final answer:
To manage DNS name resolution effectively with Office 365, you need DNS records, domain registrar access, and DNS management tools.
Step-by-step explanation:
The three items needed for Office 365 to manage DNS name resolution effectively are:
- DNS records: These records contain information about the IP addresses associated with domain names, allowing Office 365 to accurately resolve DNS queries.
- Domain registrar access: This is required to make necessary changes to the domain's DNS settings to ensure proper name resolution.
- DNS management tools: These tools, provided by Office 365, enable administrators to control and configure the DNS settings for their domain.
