Question 1

STP port state Blocking

Answer 1

Not forwarding frames listening to BPDUs

Question 2

STP port state Listening

Answer 2

Receving and transmitting BPDUs, discovering the topology

Question 3

STP port state Learning

Answer 3

Populating the CAM table with MAC addresses

Question 4

STP port state Forwarding

Answer 4

Actively participating in frame forwarding

Question 5

STP port state Disabled

Answer 5

Not participating in STP

Question 6

STP Max Age Timer

Answer 6

Length of time to wait to hear from root - 20 sec default

Question 7

STP Forward Delay Timer

Answer 7

Amount of time spent at both listening and learning states - 15 seconds default

Question 8

RSTP port state Discarding

Answer 8

prevents the forwarding of data frames, breaking layer 2 loops

Question 9

RSTP port state Learning

Answer 9

accepts data frames to populate the MAC table to limit flooding of unknown unicast frames

Question 10

RSTP port state Forwarding

Answer 10

forwarding switch ports determine the topology, after a change in topology or sync only after a proposal and agreement process

Question 11

RSTP Link type p2p

Answer 11

port is operating in full duplex mode the port is connected to a single switch device at the other end of the link

Question 12

RSTP Link type shared

Answer 12

Port is operating in half duplex mode, the port is connect to a shared media where multiple switches might exist ex hub

Question 13

RSTP edge port

Answer 13

is a switch port that is never intended to be connected to another switch device

Question 14

RSTP Topology Change

Answer 14

Only non-edge ports that are moving the the forwarding state cause a topology change. A port that is moving to blocking does not generate a TC
