100-160 Question 72
Select 3A company has a network with the following characteristics: it uses private IP addresses within the 192.168.0.0/24 range, separates different departments into VLANs, and has a single public IP address for internet access. Which of the following technologies are being utilized in this network design?
- A
Network Address Translation (NAT)
- B
Classless Inter-Domain Routing (CIDR)
- C
MAC Address Filtering
- D
Network Segmentation
- E
IPv6 Addressing
Show answer and explanation
Correct answers: A, B, D
Explanation
The network described makes use of NAT for translating private IP addresses to a public IP address for internet access, CIDR notation to define the subnet mask (/24), and VLANs for network segmentation. MAC address filtering and IPv6 addressing are not relevant to the scenario provided.
- A. Correct.
Correct. NAT allows the private IP addresses in the 192.168.0.0/24 range to access the internet using a single public IP address.
- B. Correct.
Correct. The /24 notation is an example of Classless Inter-Domain Routing (CIDR), which specifies the subnet mask.
- C. Incorrect.
Incorrect. MAC address filtering is not specifically mentioned in this scenario and is unrelated to the technologies described.
- D. Correct.
Correct. VLANs are a form of network segmentation, separating departments into different logical networks.
- E. Incorrect.
Incorrect. IPv6 addressing is not mentioned in the scenario, as the network uses IPv4 private IP addresses (192.168.0.0/24).
