The administrator has looked at the logs of L2SW1 and found that FastEthernet1/1 was in an error-disabled state.Using command line access on L2SW1, the administrator issued the following commands in configuration mode:
L2SW1(config)# interface FastEthernet 1/1
L2SW1(config-if)# shutdown
L2SW1(config-if)# no shutdown
The administrator checked the logs of L2SW1 and found the following:
Mar 30 02:23:17.588: %PM-4-ERR_DISABLE: bpduguard error detected on Fa1/1, putting Fa1/1 in err-disable state
The administrator checked the software configuration of the switch port and found the following:
interface FastEthernet1/1
switchport access vlan 310
switchport mode access
speed 100
duplex full
no mdix auto
spanning-tree portfast
spanning-tree bpduguard enable
Why has the port gone error-disabled?
A. interface FastEthernet1/1 is configured as an access port on the wrong VLAN.
B. There is a duplex mismatch between interface FastEthernet1/1 and the E-Tap.
C. The E-Tap is not configured as a ring supervisor causing a loop on interface FastEthernet1/1.
D. The E-Tap is configured at 10Mbps and the switch port is configured at 100Mbps.

C. MRP can support rings of up to 250 devices
D. MRP is only supported on network switches
Answer: B
QUESTION 64
Refer to the exhibit. What issue does this topology present for the represented traffic flow?
A. Standard Produce/Consume traffic is not suitable for an 802.11 wireless environment.
B. Only one of the Work Group Bridges can transmit at a time, because 802.11 is half duplex.
C. The Converged Plant-wide Ethernet best practices for 802.11 wireless don’t allow for PAC to PAC traffic.
D. I/O control traffic should utilize the 2.4 GHz band based on best practices.
Answer: B
