Q 15
A NAT gateway automatically connects outbound to the internet after being attached to a public IP address or prefix and a subnet. A NAT gateway takes priority over Azure Load Balancer with outbound rules, instance-level public IP addresses on virtual machines (VMs), and Azure Firewall for outbound connectivity. https://learn.microsoft.com/en-us/azure/nat-gateway/faq#how-can-i-use-a-nat-gateway-to-connect-outbound-in-a-setup-where-i-m-currently-using-a-different-service-for-outbound

Q11 Answers as Y N N
Y - Based on this From MS Zonal: You can place your NAT gateway resource in a specific zone for a region. When NAT gateway is deployed to a specific zone, it will provide outbound connectivity to the internet explicitly from that zone. The public IP address or prefix configured to NAT gateway must match the same zone. NAT gateway resources with public IP addresses from a different zone, zone-redundancy or with no zone aren't allowed. NAT gateway can provide outbound connectivity for virtual machines from other availability zones different from itself. The virtual machine’s subnet needs to be configured to the NAT gateway resource to provide outbound connectivity. Additionally, multiple subnets can be configured to the same NAT gateway resource.
2- N - Subnet 2 is not associated with NATgateway1
3- N - Considering that Public IP prefixes are of CIDR /28-31 and from the question Prefix 1 /28 = 16 IPs /29 = 8 IPs /30 = 4 IPs and smallest /31 = 2 IPs Implies CIDR /31
