Explanation:

802.1X is a port-based Network Access Control (NAC) method that enforces authentication before allowing access to the network. It uses a RADIUS server for identity verification and policy enforcement, ensuring only authorized users/devices gain access.
* A. Standard ACL filters traffic by IP, not identity.
* B. MAC filtering controls devices by hardware address but can be spoofed.
* D. SSO (Single Sign-On) provides user convenience across services, not network-level access control.

* Domain: Network Security - NAC, 802.1X authentication, identity-based access.

MIBs (Management Information Bases) define the variables and objects that SNMP can query on a device. If the monitoring server authenticates but cannot interpret the data, it likely lacks the correct MIB for that vendor or model. Importing the proper MIB allows the monitoring server to correctly display device status and metrics.
A . Using a public community string is insecure and not related to missing MIBs.
C . Switchport analyzer (SPAN) captures traffic for packet analysis, not SNMP monitoring.
D . SNMPv3 privacy adds encryption but doesn't fix missing MIB interpretation.

Explanation:
(Note: Ips will be change on each simulation task, so we have given example answer for the understanding) To perform a network discovery by entering commands into the terminal, you can use the following steps:
Click on each switch to open its terminal window.
Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.
Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.
Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch.
Fill in the missing information in the diagram using the drop-down menus provided.
Here is an example of how to fill in the missing information for Core Switch 1:
The IP address of Core Switch 1 is 192.168.1.1.
The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2: 192.168.2.0/24, VLAN 3:
192.168.3.0/24.
The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2.
The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2.
The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4.
You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.

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).
