Statement 1 is TRUE (Yes). The VM1 exhibit shows that the virtual machine is located in Subnet1. The Subnet1 exhibit explicitly shows that it is configured to use NATgateway1 as its NAT gateway. Therefore, VM1 will use NATgateway1 for all outbound internet traffic.

Statement 2 is FALSE (No). The NATgateway1 exhibit shows that it is associated with only one subnet. Since we know from the Subnet1 exhibit that Subnet1 is associated with NATgateway1, it follows that Subnet2 is not. A NAT gateway only serves the subnets it is explicitly associated with.

Statement 3 is FALSE (No). The NATgateway1 exhibit indicates it has 0 Public IP addresses but 1 Public IP prefix. A public IP prefix is a contiguous range of public IP addresses. When a NAT gateway uses a public IP prefix, it can use any of the IP addresses within that range for outbound connections. Therefore, it is not guaranteed that all virtual machines will use the same single public IP address.

Reference: Under the "Outbound connectivity with NAT" section, it states: "When a NAT gateway is configured on a subnet, all outbound connectivity uses the static public IP addresses of the NAT gateway. A virtual machine without a public IP address in a subnet configured with NAT gateway can have outbound connectivity." This supports the answer for Statement 1.

Reference: In the "Subnets" section, the documentation clarifies: "A NAT gateway can be associated with one or more subnets in a virtual network. When a NAT gateway is associated with a subnet, it provides outbound connectivity for all virtual machines within that subnet." This supports the reasoning for Statement 2, as a subnet must be explicitly associated.

Reference: Under the "Public IP prefixes" section, it says: "A public IP prefix is a contiguous range of standard SKU public IP addresses... Once a prefix is associated with a NAT gateway, all of the IP addresses of the prefix can be used for outbound connections." This confirms that multiple IPs are available from the prefix, supporting the answer for Statement 3.
