c) IP, IPX, and bridging
d) LLC and SNAP

Answer

Question 3.
For what protocols does RFC 2225 specify ATMARP?

Question 1.
What types of VCs does RFC 2684 support?

a) both PVCs and SVCs, depending on the ATM network
b) both PVCs and SVCs
c) PVCs for Layer 2 data and SVCs for Layer 3 data
d) PVCs, SVCs, and Soft VCs

Answer
b) both PVCs and SVCs

Explanation
RFC 2684, by definition, supports both PVCs and SVCs.

Its implementation depends on what the ATM cloud supports, but VC support is not a restrictive point.

Question 2.
What encapsulation methods are specified by RFC 2684?

a) LLC1, LLC2, and SNAP
b) LLC/SNAP and MUX
c) IP, IPX, and bridging
d) LLC and SNAP

Answer
b) LLC/SNAP and MUX

Explanation
RFC 2684 specifies LLC/SNAP and MUX encapsulation methods. LLC/SNAP encapsulation is used to carry multiple protocols on a single VC and MUX encapsulation is used to carry a single protocol on a single VC.

Question 3.
For what protocols does RFC 2225 specify ATMARP?

a) all Layer 3 protocols that need resolution of Layer 3 addressing to ATM addressing
b) only IP
c) only IP global addressing and ATM global addressing
d) between Layer 3 addressing and ATM VC numbers

Answer
b) only IP

Explanation
RFC 2225 specifies ATMARP only for IP. This is why it is also called Classical IP.
