Which port state will switch ports immediately transition to when configured for PortFast?

forwarding

After the election of the root bridge has been completed, how will switches find the best paths to the root bridge?

Each switch will analyze the sum of all port costs to reach the root and use the path with the lowest cost.

Which is the default STP operation mode on Cisco Catalyst switches?

PVST+

What value determines the root bridge when all switches connected by trunk links have default STP configurations?

MAC address

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?

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

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.)

PortFast, edge port

Which three port states are used by Rapid PVST+? (Choose three.)

discarding, forwarding, learning

When PVST is running over a switched network, which port state can participate in BPDU frame forwarding based on BPDUs received, but does not forward data frames

listening

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

root port

Which two statements describe a switch port that is configured with PortFast? (Choose two.)

The switch port should never receive BPDUs, The switch port immediately transitions from blocking to the forwarding state.

What is one way to correct a spanning tree failure?

Manually remove redundant links in the switched network.

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

VLAN ID

An administrator is troubleshooting a switch and wants to verify if it is a root bridge. What command can be used to do this?

show spanning-tree

What is an accurate description of redundancy?

designing a network to use multiple paths between switches to ensure there is no single point of failure

Which three components are combined to form a bridge ID? (Choose three.)

Bridge priority, Extended system ID, MAC address

What is an advantage of PVST+?

PVST+ optimizes performance on the network through load sharing using multiple root bridges.

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

Learning, Forwarding

What two features does Spanning Tree Protocol (STP) provide to ensure proper network operations? (Choose two.)

Redundant links between Layer 2 switches, Removing single points of failure with multiple Layer 2 switches

Which PVST+ feature ensures that configured switch edge ports do not cause Layer 2 loops if a port is mistakenly connected to another switch?

BPDU guard

What is an advantage of using STP in a LAN?

It temporarily disables redundant paths to stop Layer 2 loops

Which two statements regarding a PortFast enabled switch port are true? (Choose two.)

The port immediately transitions from blocking to forwarding state, The port should never receive BPDUs
