A switch running STP is classified as a backup bridge. What state is it in?
Blocking
A switch running STP is in the listening state. A message destined for a different network segment arrives at the switch. Which of the following best describes what the switch will do?
It does not record address or segment information. It does not forward the message.
A switch is running STP is in the learning state. A message destined for a different network segment arrives at the switch. Which of the following best describes what the switch will do?
It uses the source MAC address and network segment information to build its bridge database, but does not forward the message.
Switches running STP are in the process of exchanging BPDUs and redefining their roles. Which port state are the switches currently in?
Listening
Which statements accurately describe the port states of both bridges and switches? (Select two.)
Ports in a blocked state still receive BPDUs. In the learning state, the MAC address table can be populated, but frames are not forwarded.
You need to configure spanning tree on a Cisco switch. You'd like to use a protocol that conforms to the 802.1w standards. Which protocol should you use?
Rapid PVST+
Which of the following features dynamically places switch ports in blocking or forwarding states?
Spanning tree
Which of the following solutions would you implement to eliminate switching loops?
Spanning tree
You manage a network that uses multiple switches. You want to provide multiple paths between switches so that if one link goes down, an alternate path is available. Which feature should your switch support?
Spanning tree
You manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. Which feature prevents switching loops and ensures there is only a single active path between any two switches?
Spanning tree Spanning tree is a protocol on a switch that allows the switch to maintain multiple paths between switches within a subnet. The spanning tree protocol runs on each switch and is used to select a single path between any two switches.
Which problem does the spanning tree protocol prevent?
Switching loops from developing when redundant paths are implemented between switches.
