Which statements accurately describe advantages or disadvantages of deploying NAT for IPv4? (Choose two.)

The statement that NAT helps slow down IPv4 address depletion is indeed correct. Network Address Translation (NAT) allows multiple devices on a local network to share a single public IP address. By enabling several devices to connect to the internet using one address, NAT effectively extends the lifespan of the IPv4 address space. This is particularly valuable in a time when the number of available IPv4 addresses is limited, as it reduces the demand for multiple public IP addresses for every device in a local network, thereby alleviating some of the pressure on the overall pool of available IPv4 addresses.

While other choices touch on potential impacts of NAT, they do not demonstrate the same fundamental benefit that deploying NAT provides against address depletion.
