Explanation:

In Azure, DNS resolution order follows a specific hierarchy based on custom DNS configurations at the virtual network (VNet) and network interface (NIC) levels.
According to Microsoft Azure Administrator documentation, when you specify custom DNS servers for a virtual network, those DNS servers become the default for all virtual machines connected to that VNet - unless a specific VM's network interface has its own DNS settings configured. In that case, the NIC-level configuration overrides the VNet-level configuration.
Here's how it applies to this scenario:
VNET1 has been configured with a custom DNS server of 193.77.134.10 (visible in the VNet's DNS configuration screenshot).
VM1 does not have a custom DNS server specified on its NIC, so it inherits the VNet-level DNS server (193.77.134.10).
VM2 and VM3 both have explicit custom DNS settings pointing to 192.168.10.15 at the NIC level. Since NIC-level settings take precedence over the VNet's configuration, these VMs will use 192.168.10.15 for all DNS queries.
This hierarchy is described in Azure documentation under:
"DNS name resolution for virtual machines in Azure virtual networks," which explains that NIC-specific settings override VNet settings, and if no custom DNS is defined at either level, Azure's default internal DNS (168.63.129.16) is used.
In summary:
VM1 inherits DNS = 193.77.134.10 (Yes)
VM2 uses custom DNS = 192.168.10.15 (No for 193.77.134.10)
VM3 uses custom DNS = 192.168.10.15 (Yes)
Thus, the correct and Microsoft-verified answers are:
# VM1: Yes, VM2: No, VM3: Yes

Explanation:
Box 1: 10 years
The yearly backup point occurs to 1 March and its retention period is 10 years.
Box 2: 36 months
The monthly backup point occurs on the 1
of every month and its retention period is 36 months.
Note: Azure retention policy takes the longest period of retention for each backup. In case of conflict between
2 different policies.

To meet the specified requirements for creating an Azure Storage account that supports Azure Data Lake Storage, minimizes costs, and automatically replicates to a secondary region, the following settings are appropriate:
1## Support Azure Data Lake Storage # Enable Hierarchical Namespace
Azure Data Lake Storage Gen2 requires the Hierarchical Namespace feature to be enabled in the storage account. This allows directory-based organization and fine-grained access control for big data analytics.
# Answer: C. hierarchical namespace
2## Minimize costs for infrequently accessed data # Cool Access Tier
Azure Storage provides Hot, Cool, and Archive access tiers.
Hot = optimized for frequent access.
Cool = optimized for infrequent access (lower storage cost, higher access cost).
Archive = for offline, rarely accessed data.
For data that is infrequently accessed but still available online, Cool tier minimizes cost while maintaining accessibility.
# Answer: A. Cool access tier
3## Automatically replicate data to a secondary region # Geo-Redundant Storage (GRS) Replication options include:
LRS (Locally Redundant Storage) - single-region redundancy.
ZRS (Zone Redundant Storage) - replication within one region.
GRS (Geo-Redundant Storage) - replicates data to a secondary Azure region automatically.
RA-GRS (Read-Access GRS) - allows read access to the secondary region.
For automatic replication to a secondary region, GRS is required.
# Answer: E. geo-redundant storage (GRS)
Microsoft Documentation Extract Summary:
"Azure Data Lake Storage Gen2 is built on Azure Blob storage and requires the Hierarchical namespace setting to be enabled."
"The Cool access tier is designed for infrequently accessed data, offering reduced storage costs."
"Geo-redundant storage (GRS) replicates data to a secondary region for durability and disaster recovery." (Source: Microsoft Learn - Create and configure Azure Storage accounts)

The Storage Account Contributor role provides the necessary permissions to manage a storage account except for access to data itself. According to Microsoft's Azure RBAC documentation, this role includes the following actions:
Microsoft.Storage/storageAccounts/regenerateKey/action
Microsoft.Storage/storageAccounts/listKeys/action
Microsoft.Storage/storageAccounts/read
Therefore, a user assigned the Storage Account Contributor role can list and regenerate access keys for the assigned storage account.
Reference from Azure documentation (Built-in roles for Azure RBAC):
"Storage Account Contributor - Manage storage accounts, including access keys. Can't manage access to data." Hence, assigning Storage Account Contributor to User1 meets the requirement.
