To verify a domain name with Google Workspace and gain access to all its features, you typically need to prove that you own the domain. One of the most common methods for doing this is by adding a specific TXT record to your domain's DNS (Domain Name System) zone. Google provides this unique TXT record, and once it's published in your DNS, Google can verify your ownership. Here's why option C is the correct approach and why the others are not the standard methods for domain verification in Google Workspace: C . Request a TXT record be added to the DNS zone by your domain registrar. Google Workspace provides a unique TXT record that you need to add to your domain's DNS settings. This record contains a specific code that Google's systems check for. By finding this record in your domain's public DNS, Google can confirm that you have control over the domain and are authorized to use it with Google Workspace. You usually manage DNS records through the interface provided by your domain registrar or your DNS hosting provider. Associate Google Workspace Administrator topics guides or documents reference: The official Google Workspace Admin Help documentation on "Verify your domain for Google Workspace" (or similar titles) explicitly outlines the different methods for domain verification. Adding a TXT record is consistently presented as a primary and recommended method. The documentation provides the exact steps:Sign in to your domain host (domain registrar). Go to your domain's DNS records. Add a TXT record with the value provided by Google. Save the TXT record. In the Google Admin console, start the verification process. Google will then check for the TXT record. A . Contact Google support and request manual verification. While Google support can assist with domain verification issues, it's not the standard first step. Manual verification is usually reserved for situations where the standard methods (like TXT or CNAME records) cannot be used or have failed. You should first attempt one of the standard DNS-based verification methods. Associate Google Workspace Administrator topics guides or documents reference: The standard domain verification process, as documented in Google Workspace Admin Help, primarily involves DNS record modifications. Contacting support is usually a step taken if there are problems with these standard methods. B . Add an MX record to your DNS zone that points to Google Workspace. MX records are for directing email to the correct mail servers. While you will eventually need to configure MX records to use Gmail with your domain, adding them is not the primary step for verifying the domain's ownership. Domain verification needs to be completed before you can fully set up email and have Google manage your domain's email flow. Associate Google Workspace Administrator topics guides or documents reference: The Google Workspace Admin Help documentation clearly separates the steps for domain verification from setting up MX records for email. Verification comes first to prove ownership. D . Purchase an SSL certificate for your domain. An SSL (Secure Sockets Layer) certificate is used to secure communication between a web server and a browser, typically for websites. It is not related to verifying domain ownership for Google Workspace services. While having an SSL certificate is important for website security, it does not serve as a method for Google to confirm that you own the domain for Google Workspace setup. Associate Google Workspace Administrator topics guides or documents reference: Google Workspace domain verification methods are specifically focused on demonstrating control over the domain's DNS records. SSL certificates are a separate aspect of web security. Therefore, the correct action to verify your domain for Google Workspace is to request a TXT record from Google and add it to your domain's DNS zone through your domain registrar's management interface.
