Question 1 of 208

Which characteristic is MOST closely associated with the deployment of a demilitarized zone (DMZ)?

Answer

Suggested Answer

The suggested answer is C.

A demilitarized zone (DMZ) in a network architecture is typically associated with providing a buffer zone between the internal network and external sources like the internet. The primary characteristic of a DMZ is that it allows controlled access to external resources such as the internet, typically by placing web servers or other public-facing applications within the DMZ. This setup ensures that the internal network remains protected while allowing some level of interaction with the outside world through the firewall. Therefore, the characteristic most closely associated with the deployment of a DMZ is that Internet access through the firewall is allowed.

Exam Cybersecurity Fundamentals Specialist: Question 4 - Image 1
Answer

Suggested Answer

The suggested answer is C.

The missing layer in the Open Systems Interconnection (OSI) model is the Transport layer. This layer is responsible for end-to-end communication and error handling, and protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) operate at this layer. The Transport layer ensures complete data transfer and manages the reliability of a given link through flow control, segmentation/desegmentation, and error control.

Question 5 of 208

Which service does an Intrusion Detection System (IDS) provide?

Answer

Suggested Answer

The suggested answer is D.

An Intrusion Detection System (IDS) is designed to detect attempts to break into or misuse a computer system. It monitors network traffic for suspicious activity and alerts administrators when such activities are detected. It does not act as a physical or preventative lock on systems (as in option A), nor is it capable of blocking traffic (as in option C). While it helps identify vulnerabilities when they are exploited, it is not effective against all vulnerabilities (as in option B).
