The MDU does not need to support MPLS.

Can be used in ring networks of 4 or more nodes

Does not require the use of a layer 2 loop prevention protocol such as RSTP

The MDU does not have to be aware of the active/standby configuration

TRUE

FALSE

This is not a best practice. Any switch can be used as the root bridge.

So that you know which links will be active in your network.

To prevent a new switch from becoming root when added to the network.

To allow all ports on the root switch to become alternate ports.

Ring topologies.

Metro-to-metro topologies

H-VPLS topologies.

Partial-mesh topologies.

In a dynamic environment where MAC addresses are changing rapidly, the lower the age-time, the larger the fdb-table-size should be.

In a dynamic environment where MAC addresses are changing rapidly, the higher the age-time, the larger the fdb-table-size should be.

In a dynamic environment where MAC addresses are changing rapidly, the higher the age-time, the smaller the fdb-table-size should be.

There is no relationship between the age-time and the fdb-table-size.

Spanning tree will be disabled on the SAP that the PVST BPDU was received on.

The SAP that the PVST BPDU was received on will be disabled to prevent loops.

The spanning tree encapsulation will be dynamically changed to PVST on the SAP the PVST BPDU was received on.

The PVST BPDU will be ignored and 802.1D 2004 BPDUs will continue to be transmitted on the SAP.

The SDP must be configured to use GRE encapsulation.

The SDP must follow the same path as the user ' s SDP.

The SDP should be configured to use an RSVP signaled transport with fast reroute.

The SDP must be the same as the user ' s SDP.

Only R4 will be reachable through the VPLS.

B All devices will be reachable through the VPLS.

R4 and R3 will remain reachable.

No devices will be reachable.
