Y2 Module 5-6

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. 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.

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 never be used to connect to another switch?

• Bridge ID

• Edge port

• Extended system ID

• PortFast

• PVST+

Which three components form a bridge ID?

• Bridge priority

• MAC address

• IP address

• Extended system ID

• Cost

In which two port states does a switch learn MAC addresses and process BPDUs in a PVST network?

• Disabled

• Forwarding

• Listening

• Blocking

• Learning

If no bridge priority is configured in PVST, which criteria is considered when electing the root bridge?

• Lowest MAC address

• Lowest IP address

• Highest IP address

• Highest MAC address

Match the STP protocol with the correct description. (Not all options are used.)
STP

• the legacy standard for STP that runs all VLANS in a single spanning-tree instance

• A protocol that allows multiple vlans to run in a single spanning-tree instance

• a cisco enhancement of RSTP to provide a spanning-tree instance for each vlan

• an evolution that provides faster convergence

Rapid PVST+
