What are two characteristics of Frame Relay point-to-point subinterfaces? (Choose two.)
A.
They create split-horizon issues.
B.
They require a unique subnet within a routing domain.
C.
They emulate leased lines.
D.
They are ideal for full-mesh topologies.
E.
They require the use of NBMA options when using OSPF.
Explanation:
Subinterfaces are used for point to point frame relay connections, emulating virtual point to
point leased lines. Each subinterface requires a unique IP address/subnet. Remember, you
can not assign multiple interfaces in a router that belong to the same IP subnet.
