Your company has deployed 2000 VMs in a private subnet of your VPC in the us-east1 region. Each VM requires at least 128 concurrent TCP connections to a public repository for downloading software updates and packages over the internet. You must implement a Cloud NAT gateway to enable outbound NAT for these VMs while ensuring all 2000 VMs can simultaneously establish connections. Which two approaches achieve this? (Select two.)
A
Configure the NAT gateway in manual allocation mode, allocate 2 NAT IP addresses, and update the minimum number of ports per VM to 256.
B
Create a second Cloud NAT gateway with the default minimum number of ports configured per VM to 64.
C
Use the default Cloud NAT gateway's NAT proxy to dynamically scale using a single NAT IP address.
D
Use the default Cloud NAT gateway to automatically scale to the required number of NAT IP addresses, and update the minimum number of ports per VM to 128.
E
Configure the NAT gateway in manual allocation mode, allocate 4 NAT IP addresses, and update the minimum number of ports per VM to 128.
