Exam 220-1201 Topic 1 Question 173 Discussion

Actual exam question for CompTIA's 220-1201 exam
Question #: 173
Topic #: 1
A company is separating its accounting department's network from its customer service department's network.
Which of the following will accomplish this task?

Suggested Answer: C Vote an answer

Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide) CompTIA networking fundamentals describe VLANs (Virtual Local Area Networks) as a method to segment network traffic logically, even while using the same physical switch hardware.
A VLAN allows a company to:
* Separate traffic by department
* Improve security
* Reduce broadcast domains
* Control inter-department access
To separate accounting and customer service networks, VLANs are the industry-standard and the CompTIA- approved method.
Why the other options are incorrect
A). VPN - Used for secure remote connections, not internal LAN segmentation.
B). DNS - Resolves hostnames to IPs, not used for network separation.
D). DHCP - Assigns IP addresses; does not isolate network groups.
Final Answer: C
