Spanning Tree Protocol (STP) should be enabled when configuring redundant network links between switches. STP ensures that only one active path is used at a time, preventing network loops and stability issues.

The issue of WIFI users being unable to connect while WLAN users on the guest network canaccess all resources indicates a problem with channel overlap or interference. By reconfiguringthe channels, interference can be minimized, improving connectivity for WIFI users. Accordingto the table, AP 1 and AP 2 are using adjacent channels (2 and 1), which can cause interference.AP 3 and AP 4 are using non-overlapping channels (5 and 11), but they have very high RSSIvalues (-44dBm and -41dBm), which can also cause interference. A possible solution is to useonly non-overlapping channels (such as 1, 6, and 11) and adjust the power levels to avoidexcessive signal strength.Reference:Wireless Troubleshooting -- N10-008 CompTIA Network+ :5.4,Network Troubleshooting Methodology - N10-008 CompTIA Network+ : 5.1

BGP (Border Gateway Protocol) is a routing protocol used to exchange route information between public autonomous systems (AS). OSPF (Open Shortest Path First), EGRIP (Enhanced Interior Gateway Routing Protocol), and RIP (Routing Information Protocol) are all used for internal routing within a single AS. Therefore, BGP is the correct option to choose for this question.

To detect the exact break point of a fiber link, an engineer should use an OTDR (Optical Time Domain Reflectometer). This device sends a series of pulses into the fiber, measuring the time it takes for the pulses to reflect back, and can pinpoint the exact location of the break.

TACACS+ (Terminal Access Controller Access Control System Plus) can be used to centrally manage credentials for various types of administrative privileges on configured network devices. This protocol separates authentication, authorization, and accounting (AAA) functions, providing more granular control over access to network resources.

RDP (Remote Desktop Protocol) is the best option for a network technician to use when installing new software on a Windows-based server in a different geographical location. This protocol allows the technician to connect to the server remotely and control it as if they were physically present.

To improve performance for videoconferencing, the company should configure Quality of Service (QoS). This technology allows for the prioritization of network traffic, ensuring that videoconferencing traffic is given higher priority and therefore better performance. Link Aggregation Control Protocol (LACP), Dynamic routing, Network load balancer, and Static IP addresses are not directly related to improving performance for videoconferencing.

Using a bottom-to-top approach means starting from the physical layer and moving up the OSI model to troubleshoot a network problem. Checking for a link light is a physical layer check that verifies the connectivity of the network cable and device. Reference:
