What does the BID field of a BPDU frame consist of?
Bridge priority, Extended system ID, MAC address
Which spanning tree protocol uses perVLAN RSTP?
Rapid PVST+
What is the primary purpose of Extended System ID in PVST+?
Unique BIDs for each VLAN
How many port states are used in PVST+ operation?
5
In root-bridge election manipulation, what action can lead to a switch becoming the root bridge?
Assigning a lower priority
What type of BPDUs does RSTP use?
Type 2, version 2
What issue at Layer 1 of the network can occur due to MAC database instability?
Continued propagation of frames
In the context of Spanning Tree Algorithm, what is the purpose of blocking redundant paths?
To prevent loop formation
Which type of port in the Spanning Tree Algorithm is closest to the root bridge?
Root port
What is the purpose of the root bridge in STP?
To serve as a reference point for STP calculations
What happens when unknown unicast frames are sent onto a network with loops?
Duplicate frames arrive at the destination device
How does STP ensure only one logical path between all destinations on the network?
By intentionally blocking redundant paths
What determines the internal root path cost from a switch to the root bridge?
The sum of individual port costs along the path to the root bridge
What information does each switch maintain locally regarding STP operation?
The BID, root ID, and root path cost
What is the default frequency of sending BPDU frames in STP?
Every two seconds
In STP, what role is automatically configured for all switch ports on the root bridge?
Designated port
What role do alternate ports play in STP operation?
Does not send or receive traffic on that segment
