Which three statements accurately describe duplex and speed settings on Cisco 2960 switches? (Choose three.)

On Cisco 2960 switches, the following statements accurately describe duplex and speed settings:

1. An autonegotiation failure can result in connectivity issues.
   • When autonegotiation fails, devices may end up with mismatched speed or duplex settings, which can lead to performance issues, such as slow throughput or a large number of collisions.
2. The duplex and speed settings of each switch port can be manually configured.
   • On a Cisco 2960 switch, you can manually configure the speed and duplex settings for each port using the speed and duplex interface configuration commands.
3. When the speed is set to 1000 Mb/s, the switch ports will operate in full-duplex mode.
   • Gigabit Ethernet standards only support full-duplex operation, so when a switch port is set to 1000 Mb/s (1 Gb/s), it will operate in full-duplex mode.

The following statements are inaccurate:

• By default, the speed is set to 100 Mb/s and the duplex mode is set to autonegotiation.
  • This is incorrect. By default, Cisco 2960 switches have their ports set to autonegotiate both speed and duplex settings.
• By default, the autonegotiation feature is disabled.
  • This is not true. By default, autonegotiation is enabled on Cisco 2960 switches.
• Enabling autonegotiation on a hub will prevent mismatched port speeds when connecting the hub to the switch.
  • Hubs do not support autonegotiation because they are not intelligent devices like switches. They operate at a single speed and do not negotiate speed or duplex settings.
