多选题Which three statements accurately describe layer 2 Ethernet switches?（）AMicrosegmentation decreases the number of collisions on the network.Bif a switch receives a frame for an unkown destination,it uses ARP to resolve the address.CSpanning Tree Protocol allows switches to automatically share vlan information.DIn a properly functioning network with redundant switched paths,each switched aegment will contain one root bridge with all its ports in the forwarding state.All other switches in that broadcast domain will have only one root port.EEstablishing vlans increases the number of broadcast domains.FSwitches that are configured with vlans make forwarding decisions based on both layer 2 and layer 3 address information.

多选题Refer to the exhibit. A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands.Which two of these changes are necessary for SwitchA to meet the requirements? （）APort security needs to be globally enabled.BPort security needs to be enabled on the interface.CPort security needs to be configured to shut down the interface in the event of a violation.DPort security needs to be configured to allow only one learned MAC address.EPort security interface counters need to be cleared before using the show command.FThe port security configuration needs to be saved to NVRAM before it can become active.

单选题A company is experiencing network delays. The network administrator discovers that a worker in a location far from the MDF has connected an old 10BASE-T switch with redundant links to the existing network. How could this action be responsible for the impaired network performance?（）A
Connecting a host to the old switch has created a broadcast storm.B
The 10BASE-T switch forced the entire network to be reduced to 10 Mbps operation.C
The old switch does not support VLANs, which has disabled the VLAN configuration of the entire the network.D
The old switch does not support full-duplex operation, effectively forcing half-duplex operation throughout the network.E
Spanning Tree Protocol has elected the old switch as the root bridge, creating inefficient data paths through the switched network.
