1.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.

2.A company has a small network,consisting of a single switch and a single router.The switch has been configured with two vlans,and route-on-a-stick is being configured on the router for inter-vlan routing.A trunk is configured to connect the switch to the router.What is the minimum number of router subinterfaces that are required for all the vlans to communicate?（）A. oneB. threeC. twoD. zero

3.Refer to the exhibit. Given the output shown from this Cisco Catalyst 2950, what is the most likely reason that interface FastEthernet 0／10 is not the root port for VLAN 2?()A.This switch has more than one interface connected to the root network segment in VLAN 2.B.This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.C.This switch interface has a higher path cost to the root bridge than another in the topology.D.This switch has a lower bridge ID for VLAN 2 than the elected designated switch.

4.A new Catalyst switch is connected to an existing switch using a crossover cable. As a result of this, what would the switch port link lights display?()A. The switch port link lights will be off on both switches indicating the ports are not connected.B. The switch port link light will be off on one switch indicating that STP has disabled the port.C. The switch port link lights will flash amber indicating an error.D. The switch port link lights will be green indicating normal operation.
