Before inserting a new switch in the network， the network administrator checks that the VTP domain name is correct， the VTP mode is set to server， and revision is lower than the switches in the network. The administrator then configures interfaces and trunks， erases existing VLANs， and connects the switch to the network. Following that procedure， there is no connectivity in the network. What is a possible cause of this problem？（）
A

Because the configuration revision of the new switches is lower than the rest of the network， it can change the VLAN database of the other switches.

B

As a VTP server， the new switch deleted all VLANs of the network.

C

Erasing VLANs increases the VTP configuration revision.

D

Since the configuration revision of the network is higher than the new switch， the VLAN database was automatically synchronized.

    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.
