The network administrator checks the physical connections to the workstation labeled User 3 and sees the Ethernet is properly connected. However, the network interface’s indicator lights are not blinking on either the computer or the switch. Which of the following Is the most likely cause?  \nA: The switch failed.  \nB: The default gateway is wrong.  \nC: The port Is shut down.  \nD: The VLAN assignment is incorrect.  \nCorrect Answer:  \nC  \nExplanation:  \nThe key symptom is the lack of indicator lights on both the computer's network interface and the switch port, despite a proper physical connection. This indicates a failure at the Physical Layer (Layer 1) of the OSI model, where a link is established. An administratively shut down port on a managed switch is a specific configuration that disables the port, preventing it from sending or receiving the electrical signals necessary to form a link. This perfectly matches the observed symptoms, making it the most likely cause for an issue isolated to a single connection.  \nWhy Incorrect Options are Wrong:  \nA: The switch failed. A complete switch failure would impact all connected devices, not just a single user. The problem described is isolated.  \nB: The default gateway is wrong. This is a Layer 3 (Network Layer) configuration issue. It would not prevent a Layer 1 link from being established; indicator lights would be active.  \nD: The VLAN assignment is incorrect. This is a Layer 2 (Data Link Layer) configuration issue. The physical link would still be established, and the indicator lights would be on.  \nReferences:  \n1. IEEE Std 802.3-2018 (IEEE Standard for Ethernet): Clause 22, \"Reconciliation Sublayer (RS) and Media Independent Interface (MII),\" specifies management functions for Physical Layer devices (PHYs) . These functions include the ability to administratively disable a port,  \nwhich would prevent the Auto-Negotiation process and link establishment, resulting in nolink lights.  \nURL: [https://ieeexplore.ieee.org/document/8457469](https://ieeexplore.ieee.org/document/8457469) (See Clause 22 .2.4, Management Functions)  \n2. MIT OpenCourseWare, 6.033 Computer System Engineering, Spring 2018: Lecture 10,\"The Link Layer,\" explains that for communication to occur, a physical link must be established between devices. An administratively disabled port prevents the physical signaling required to create this link.  \nURL: [https://ocw.mit.edu/courses/6-033-computer-system-engineering-spring-](https://ocw.mit.edu/courses/6-033-computer-system-engineering-spring-)[ ](https://ocw.mit.edu/courses/6-033-computer-system-engineering-spring-)[2018/resources/mit6033s18lec10/](2018/resources/mit6033s18lec10/) (See section on Framing and Physical Layer)  \n3. Cisco Systems, Inc. Official Documentation: While specific to a vendor, the behavior is industry-standard. Documentation for interface commands shows that using the shutdown command on a switch port interface places it in an \"administratively down\" state, disabling all traffic and turning off the port's link light.  \nURL: [https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-](https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-)[ ](https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-)[253se/command/reference/cr/cli1.html\\#wp11112131](253se/command/reference/cr/cli1.html#wp11112131) (Description of the shutdown interface configuration command)  \nQuestion: 2  \nAn administrator is setting up an SNMP server for use in the enterprise network and needs to create device ID","cbCaitHRlbVM9lOa","https://ap.wps.com/l/cbCaitHRlbVM9lOa","pdf",287441,59,"English","# Demo Questions\n## Question 1: Physical layer link failure diagnosis\n## Question 2: Function of a MIB in SNMP","[{\"question\":\"Why are there no indicator lights on the computer and switch port even when the Ethernet cable is connected?\",\"answer\":\"The most likely cause is a port that is administratively shut down on a managed switch, which disables the link at OSI Layer 1 and prevents the port from sending or receiving electrical signals.\"},{\"question\":\"What is the role of a MIB in SNMP management?\",\"answer\":\"A MIB is a hierarchical database that defines managed objects on network devices.
