To monitor server availability, SNMP traps are the best choice. SNMP (Simple Network Management Protocol) allows devices to send alerts (traps) when certain conditions are met, such as server downtime or high resource usage.

Breakdown of Options:

A. Packet capture – Capturing packets provides insights into network traffic but does not actively monitor server availability.

B. Data usage reports – These analyze network traffic consumption but do not indicate whether a server is available or not.

C. SNMP traps – Correct answer. SNMP traps notify administrators of server issues in real time.

D. Configuration monitoring – This tracks configuration changes rather than availability.

Spanning Tree Protocol (STP) is designed to detect and prevent Layer 2 loops by blocking redundant paths. If loops are possible in the design, enabling STP ensures network stability.

B. Port security controls endpoint MAC addresses, not loops.

C. Speed limits address bandwidth, not loop prevention.

D. 802.1Q tagging allows VLAN separation but does not resolve loops.

To troubleshoot all the network components and review the cable test results, you can use the following steps:

Click on each device and cable to open its information window.

Review the information and identify any problems or errors that may affect the network connectivity or performance.

Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.

Fill in the remediation form using the drop-down menus provided.

Here is an example of how to fill in the remediation form for PC1:

The component with a problem is PC1.

The problem is Incorrect IP address.

The solution is Change the IP address to 192.168.1.10.

You can use the same steps to fill in the remediation form for other components.

To enter commands in each device, you can use the following steps:

Click on the device to open its terminal window.

Enter the command ipconfig /all to display the IP configuration of the device, including its IP address, subnet mask, default gateway, and DNS servers.

Enter the command ping  to test the connectivity and reachability to another device on the network by sending and receiving echo packets. Replace with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.

Enter the command tracert  to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets with increasing TTL values. Replace with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.

Here is an example of how to enter commands in PC1:

Click on PC1 to open its terminal window.

Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1.

Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets.

Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.

You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.

Jumbo frames are Ethernet frames with a payload greater than the standard maximum transmission unit (MTU) of 1500 bytes. Configuring jumbo frames can reduce overhead and increase efficiency in storage networks by allowing more data to be sent in each frame, thus reducing the number of frames needed to transmit the same amount of data.

Reduced Overhead: By sending larger frames, the relative overhead for headers and acknowledgments is reduced.

Increased Efficiency: Larger frames mean fewer packets to process, leading to better utilization of network bandwidth and improved performance in high-throughput environments like storage networks.

Configuration: Requires support from all devices in the network path, including switches and network interface cards (NICs).
