NET 2 Checkpoint Exam: Redundant Networks Exam

What additional information is contained in the 12-bit extended system ID of a BPDU?

• MAC address

• VLAN ID

• IP address

• port ID

During the implementation of Spanning Tree Protocol, all switches are rebooted by the network administrator. What is the first step of the spanning-tree election process?

• Each switch with a lower root ID than its neighbor will not send BPDUs.

• All the switches send out BPDUs advertising themselves as the root bridge.

• Each switch determines the best path to forward traffic.

• Each switch determines what port to block to prevent a loop from occurring.

Which STP port role is adopted by a switch port if there is no other port with a lower cost to the root bridge?

• designated port

• root port

• alternate

• disabled port

Which two concepts relate to a switch port that is intended to have only end devices attached and intended never to be used to connect to another switch? (Choose two.)

• bridge ID

• edge port

• extended system ID

• PortFast
