True

False

15. In dynamic NAT, what happens when all public IPs in the pool are in use and a new internal host initiates a connection?

The connection is immediately established

The request is queued until an IP becomes available

The connection is denied

The host is assigned a private IP temporarily

16. A web server behind a NAT device must be accessible from the internet. Which NAT configuration would you use?

19. Static NAT requires a pool of public IP addresses equal to the number of internal hosts needing external access.

True

False

20. In PAT, how does the router distinguish between multiple internal hosts using the same public IP?

By MAC address

By port number

By subnet mask

By VLAN ID

21. A company needs to allow 200 internal hosts to access the internet using only 5 public IP addresses. Which NAT method is most appropriate?

Static NAT

Dynamic NAT

Port Address Translation (PAT)

Bidirectional NAT
