NAT Quiz: Static, Dynamic Or PAT?

1. Which NAT type creates a permanent one-to-one mapping between a private IP and a public IP?

Static NAT

Dynamic NAT

Port Address Translation

Overloaded NAT

2. 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

3. A network uses static NAT exclusively. What is a significant disadvantage of this approach for a large network?

It requires many public IP addresses

It is difficult to configure

It does not support IPv6

It reduces bandwidth significantly

4. Which NAT type automatically assigns public IPs from a pool to internal hosts on a first-come, first-served basis?

Static NAT

Dynamic NAT

PAT

Conditional NAT

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

Dynamic NAT

Static NAT with port forwarding

PAT only

No NAT

6. A network administrator configures a 1:1 NAT mapping where 192.168.1.50 always translates to 203.0.113.10. What type of NAT is this?

Dynamic NAT

Static NAT

PAT

Conditional NAT

Submit

8. 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

9. A company has 50 internal servers and 50 public IPs. Which NAT type provides the most direct external access?

Dynamic NAT

Static NAT

PAT

Hybrid NAT

10. Which statement best describes the relationship between PAT and overloading?

PAT and overloading are completely different technologies

PAT is a form of overloading using port numbers

Overloading is more efficient than PAT

They serve opposite functions in NAT

11. Which NAT type is most commonly used in small office/home office (SOHO) environments?

Static NAT

Dynamic NAT

Port Address Translation (PAT)

Stateless NAT

12. Static NAT translations are typically configured manually on the router.

True

False

13. Dynamic NAT requires pre-configured address mappings before traffic flows through the router.

True

False

14. 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

15. In static NAT, if the public IP is taken offline, internal hosts mapped to that IP lose connectivity.

True

False

Submit

18. Which NAT type best supports inbound connections initiated from external networks?

Dynamic NAT

Static NAT

PAT

All equally support inbound connections

Submit

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

True

False

21. When dynamic NAT releases an IP address back to the pool, that address can be immediately reassigned to a different internal host.

True

False
