Question

Hotspot Question You have the Azure virtual machines shown in the following table. VNET1, VNET2, and VNET3 are peered. VM4 has a DNS server that is authoritative for a zone named contoso.com and contains the records shown in the following table. The virtual networks are configured to use the DNS servers shown in the following table. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Answer:

Explanation

VM1 is in VNET1 and VM2 is in VNET2. Both VNET1 and VNET2 are configured to use VM4's DNS server (which is authoritative for contoso.com), so both VM1 and VM2 can successfully resolve server1.contoso.com to 131.107.3.3 - hence both statements are 'Yes'. VM3 is in VNET3, which is configured to use Azure's default DNS (or a different DNS server that is NOT VM4), so it cannot resolve server2.contoso.com via VM4's zone, making the third statement 'No' - VM3 cannot resolve that name to 131.107.2.4.
