CompTIA Network+ N10-009 Reddit Questions

A content filter blocks access to specific websites based on category, URL, or keywords. This is the best solution to restrict gambling websites.

Breakdown of Options:

A. ACLs – Control network access, not specific web content.

B. Content filter – ✅ Correct answer. Used to block access to unwanted websites.

C. Port security – Prevents unauthorized device connections, not web traffic filtering.

D. Screened subnet – A DMZ isolates public-facing servers, not user restrictions.

The most likely cause is that the switch ports were previously configured for a different VLAN than the one the users’ computers are on. If the native VLAN on the port doesn’t match the end device’s VLAN, communication fails.

A. Ports are error-disabled: Would result in no link at all, not common across multiple ports unless a violation occurred.

C. MDIX issue: Auto-MDIX eliminates most crossover problems on modern switches.

D. Ports are trunk ports: While possible, typical user devices should be on access ports, but if the port is incorrectly trunked, it can cause similar issues. However, “incorrect VLAN” is more precise here.

In this case, the accountant ' s access is limited to only the financial department ' s shared folders, ensuring that they cannot access other parts of the network unnecessarily. This reduces the risk of unauthorized access and potential data breaches. References: CompTIA Network+ Exam Objectives and official study guides.
