Question

You have two Azure virtual machines as shown in the following table.

You create the Azure DNS zones shown in the following table.

You perform the following actions:
✑ ׀¢׀¾ fabrikam.com, you add a virtual network link to vnet1 and enable auto registration.
✑ For contoso.com, you assign vm1 and vm2 the Owner role.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:

Accepted Answer

- **VM1 will have a host record in contoso.com (No):** `contoso.com` is a Public DNS zone. Public DNS zones do not support virtual network linking or DHCP auto-registration. Assigning VM1 and VM2 the Owner role on the `contoso.com` resource only grants control-plane permissions and does not generate DNS host (A) records.
- **VM1 will have a host record in fabrikam.com (Yes):** `fabrikam.com` is a Private DNS zone linked to `vnet1` with auto-registration enabled. Since VM1 is deployed in `vnet1`, Azure will automatically register its host record (A record) in `fabrikam.com` (ignoring the OS-configured primary DNS suffix of `contoso.com`).
- **VM2 will have a host record in fabrikam.com (Yes):** VM2 is also deployed in `vnet1`. Although VM2 runs Linux (Ubuntu), Azure Private DNS auto-registration is OS-agnostic and automatically creates host records for all virtual machine instances deployed in the linked virtual network.
