(h p://ccnaanswers.com/wp-content/uploads/CCNA1FinalExamV4.0Answers28.jpg)Refer to the exhibit. How does SW1 manage traffic coming from Host A?SW1 drops the traffic because it is untagged.SW1 leaves the traffic untagged and forwards it over the trunk.SW1 tags the traffic with the lowest VLAN ID value and forwards it over the trunk link.SW1 encapsulates the traffic with 802.1Q encapsulation and forwards it over the trunk link.50. An administrator is troubleshooting a PC on the network which is suffering from slow and intermi entconnectivity. The PC has a ping success rate to the default gateway of less than half the ping a empts. Other PCson the switch can consistently ping the default gateway. The switch port is configured for auto duplex and the PCis configured for full duplex. What will commonly cause this problem?The PC is set to full duplex. The switch port fails to autonegotiate the duplex se ing and defaults to half duplex,which causes a duplex mismatch.The switch traffic is exceeding available frame buffers. The result is that frames are being dropped.The PC and the default gateway have different bandwidth Ethernet ports.The default gateway is not on the same switch that the PC is.51.
