Homework Help: Questions and Answers: Which firewall is able to assess internet traffic and block unsolicited communications?
a) NGFW
b) NAT
c) SMLI
d) None are correct
Answer:
First, let’s understand the question: We need a firewall that can assess internet traffic and block unsolicited communications.
Given Options: Step by Step Answering
a) NGFW (Next-Generation Firewall)
- NGFWs provide deeper inspection capabilities beyond what traditional firewalls offer.
- They can assess internet traffic, including analyzing packet contents and blocking unsolicited or malicious communications.
- They typically include features like application control, intrusion prevention, and content filtering.
b) NAT (Network Address Translation)
- NAT translates private IP addresses to a public IP address.
- It helps in hiding the internal IP addresses of devices but is not responsible for assessing or blocking unsolicited communications like a firewall.
c) SMLI (Stateful Multi-Layer Inspection)
- Stateful Multi-Layer Inspection is a feature of many firewalls that allows them to inspect data packets at different layers.
- While this feature helps in traffic monitoring, it’s usually found in traditional firewalls and doesn’t inherently provide the advanced inspection capabilities needed to block sophisticated unsolicited communications.
d) None are correct
- Since NGFW is the correct answer, this option is incorrect.
Final Answer:
Based on the above analysis, the correct answer is:
a) NGFW
NGFWs are specifically designed with advanced capabilities to assess internet traffic and block unsolicited communications. They can perform deep packet inspection, understand application behavior, and make intelligent decisions about blocking unwanted traffic.
