Vocabulary Exercise: Matching
Match the definition on the left with a term on the right. This exercise is not necessarily a one-to-one
matching. Some definitions may be used more than once and some terms may have multiple definitions.
Definition
a. calculated based on the speed of the link
b. port is only receiving BPDUs
c. status messages sent between switches every
2 seconds
d. 20 seconds or a cycle of 10 BPDUs
e. the time it takes for a port to transition from
the listening state to the learning state or from
the learning state to the forwarding state
f. actively building a MAC address table but not
forwarding user traffic
g. used in redundantly switched networks to
create a loop-free logical topology
h. can send and receive traffic
i. port is sending and receiving BPDUs, but not
user traffic
j. without loop avoidance, frames are flooded
endlessly
k. includes the priority and MAC address of the
bridge
l. lowest-cost path from the non-root bridge to
the root bridge
m. an improved version of IEEE 802.1d
n. reduces the time of reconvergence when a
topology change occurs in a redundantly
switched network
o. called “blocking” in IEEE 802.1d
p. ports connected to a single end station
q. only one in a given network; all ports are
designated ports
r. operating in full-duplex mode
s. a port that is currently in the discarding state,
but will transition to forwarding if the designated
root port on that segment fails
t. automatically transitions from the blocking
state to the forwarding state
Term
j broadcast storms
g Spanning Tree Protocol (STP)
k bridge ID (BID)
