Designated

Alternate

Backup

Front 6

What is the default hello timer length for 802.1s?

Back 6

Back 7

Disabled

Blocking

Listening

Learning

Forwarding

Front 8

What are the different port roles for 802.1s?

Back 8

Front 9

What are the different steps in spanning tree operation?

Back 9

Determine root bridge

Select root port

Select designated ports

Block ports with loops

Hint 9

There are four steps.

Front 10

Define backbonefast

Back 10

PVST enhancement which enables immediate expiration of max-age timer in the event of an indirect link failure.

Hint 10

Deprecated by Rapid-PVST alternate port state. (?)

Front 11

Define portfast

Back 11

Forces switchport to immediately transition to "forwarding" state

(Designates port as "edge" in MST)

Front 12

What is the default Forward Delay timer length?

Back 12

15 seconds

Front 13

Define a RSTP Shared link.

Back 13

Potentially connects to multiple bridges (half-duplex)

Front 14

What is the default Max-age timer length?

Back 14

20 seconds

Front 15

How does spanning tree pick a root port? (Spanning tree path selection)

Back 15

Bridge with lowest root ID becomes root

Prefer neighbor with lowest cost to root

Prefer neighbor with lowest bridge ID

Prefer lowest sender port ID

Front 16

Define uplinkfast

Back 16

PVST+ enhancement which enables switches to maintain backup paths to root bridge.

Hint 16

Deprecated by Rapid-PVST backup port role.(?)

Front 17

If I want a switch to become the root, do I want high or low priority?

Back 17

Low

Hint 17

Golfing is fun

Front 18

Define BPDU Guard

Back 18

Err disables a port if a BPDU is received.

Front 19

Define Loop Guard

Back 19

Prevents a blocked port from transitioning to listening state after max age timer has expired

Front 20

Define a RSTP Point-to-Point (P2P) link.

Back 20

Connects to exactly one other bridge. (Full Duplex)

Front 21

What is the default hello timer length for 802.1d?

Back 21

2 seconds

Front 22

Define Root Guard

Back 22

Prevents a port from becoming the root port.

Front 23

Define Loop inconsistency

Back 23

When a loop guard enabled port stops receiving BPDUs, it moves to a loop-inconsistent state.

Hint 23

Loop guard

Front 24

When using the command "show spanning tree, what does the output "P2P Bound" mean?

Back 24

Connected device is outside of the MST region

Front 25

Define Root inconsistency

Back 25

A root inconsistency comes from a port trying to advertise a better root bridge than the current root bridge.

Front 26

0100.0ccc.cccc is my destination. What am I?

Back 26

CDP (Cisco Discovery Protocol)

Front 27

0180.c200.000e is my destination what am I?

Back 27

LLDP (Link Layer Discovery Protocol)
