Switch SW1 uses its Gigabit 0/1 interface to connect to switch SW2’s Gigabit 0/2 interface. SW2’s Gi0/2 interface is configured with the speed 1000 and duplex full commands. SW1 uses all defaults for interface configuration commands on its Gi0/1 interface.
Which of the following are true about the link after it comes up? (Choose two answers.)
- The link works at 1000 Mbps (1 Gbps).
- SW1 attempts to run at 10 Mbps because SW2 has effectively disabled IEEE standard autonegotiation.
- The link runs at 1 Gbps, but SW1 uses half duplex and SW2 uses full duplex.
- Both switches use full duplex.
Explanation: SW2 has effectively disabled IEEE standard autonegotiation by configuring both speed and duplex. However, Cisco switches can detect the speed used by the other device, even with autonegotiation turned off. Also, at 1 Gbps, the IEEE autonegotiation standard says to use full duplex. If the duplex setting cannot be negotiated, both ends use 1 Gbps, full duplex.
