A.Half-duplex transmission is less efficient because the frame MTU is smaller.

B.Half-duplex transmission is only 30-40% efficient because of collisions.

C.Ethernet switches support half-duplex transmission only.

D.All of the above.

A.Labels used for a LSP may be static but are usually signaled dynamically with an MPLS label signaling protocol.

B.Labels are globally significant to the MPLS network which means all labels on the LSP path must be unique.

C.A series of labels from one LER to another LER represent a logical tunnel known as an LSP.

D.Labels used for an LSP must be statically assigned by the service provider.

E.Labels are locally significant to the MPLS router which means its possible for two routers on the LSP path to use the same label.
