NAT Types and Use Cases
Match static NAT, dynamic NAT, and PAT (NAT overload) to their descriptions, use cases, and deployment characteristics for IPv4 address translation.
Some options will have multiple correct answers.
Conserves public IPs compared to static NAT but limited by pool size
Requires a dedicated public IP for each internal host
Supports multiple concurrent sessions by differentiating ports
Commonly deployed in small offices and home routers to preserve IPv4 addresses
Many-to-many mapping using a pool of public IP addresses
One-to-one mapping between a private and public IP address
Automatically assigns a public IP from the pool when traffic is initiated
Many-to-one mapping using port numbers on a single public IP
Ideal for hosting servers or devices requiring a fixed public IP
Static NAT
Dynamic NAT
PAT (NAT overload)
