NEW QUESTION # 87
A network administrator recently updated configurations on a Layer 3 switch. Following the updates, users report being unable to reach a specific file server. Which of the following is the most likely cause?

Answer: A

Explanation:
Since this issue occurred after a configuration change on a Layer 3 switch, the most likely cause is misconfigured ACLs (Access Control Lists).
ACLs control which traffic is allowed or denied, so an incorrect ACL may be blocking access to the file server.


NEW QUESTION # 88
Which of the following is the correct order of components in a bottom-up approach for the three-tier hierarchical model?

Answer: C

Explanation:
The three-tier hierarchical model in network design consists of three layers: access, distribution, and core. The access layer is where devices like PCs and printers connect to the network. The distribution layer aggregates the data received from the access layer switches before it is transmitted to the core layer, which is responsible for high-speed data transfer and routing. This approach improves scalability and performance in larger networks. Reference: CompTIA Network+ Exam Objectives and official study guides.


NEW QUESTION # 89
A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel is not labeled for easy jack identification. Which of the following tools provides the easiest way to identify the appropriate patch panel port?

Answer: A

Explanation:
A toner probe, often referred to as a toner and probe kit, is the easiest and most effective tool for identifying individual cables in a bundle, especially in situations where the patch panel is not labeled. The toner sends an audible tone through the cable, and the probe detects the tone at the other end, allowing the technician to quickly identify the correct cable.
* Functionality: The toner generates a tone that travels along the cable. When the probe is placed near the correct cable, it detects the tone and emits a sound.
* Ease of Use: Toner probes are straightforward to use, even in environments with many cables, making them ideal for identifying cables in unlabeled patch panels.
* Efficiency: This method is much faster and more reliable than manual tracing, especially in complex setups.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Details tools used for cable identification and troubleshooting.
* Cisco Networking Academy: Provides training on using toner probes and other cable testing tools.
* Network+ Certification All-in-One Exam Guide: Explains the use of different tools for network cable identification and management.
