What does STP stand for?
P 346
Spanning Tree Protocol
What is Spanning Tree Protocol?
P 346
STP is a layer 2 protocol that is used to maintain a loop-free switched network.
What is the purpose of STP
P 346
To monitor the network to find all links and make sure that no loops occur by shutting down any redundant ones.
T/F? IEEE created its own version of STP called 801.2D

What is Listening?
P 347
It is the port Listens to BPDUs to make sure no loops occur on the network before passing data frames. A port in Listening state prepares to forward data frames without populating the MAC address table.
T/F? Switches populate the MAC address table in learning and forwarding modes only.

What is STP Convergence?
P 347
When all the ports on bridges and switches have transitioned to either forwarding or blocking modes. During this phase, no data will be forwarded until the convergence event is complete.
What is RSTP 802.1w?
P 348
Rapid Spanning Tree Protocol 802.1w is a rapid convergence time when a topology change occures.
What are the differences between the 802.1w compared to 802.1 D?
P 349
- 1D 802.1w

* Disabled = Discarding
* Blocking = Discarding
* Listening = Discarding
* Learning = Learning
* Forwarding = Forwarding
What is VLAN?
P 350
It is a logical grouping of network users and resources connected to administratively defined ports on a switch
By default, can the hosts in specific VLAN communicate with the hosts that are members of another VLAN ?
P 350
No
By default, the hosts in specific VLAN cannot communicate with the hosts that are members of another VLAN. What device can be used resolve this issue?
P 353
A router
What is QoS?
P 353
Quality of service. The ability to provide a different priority for one or more types of traffic over other levels.
What is Static VLANs?
P 354
Hardware addresses of the hosts are assigned into database by an administrator.
What is Dynamic VLANs?
P 355
A Dynamic VLAN determines a host’s VLAN assignment automatically.
