Which of the following statements are true when you compare DSCP and IP Precedence to each other? (Choose all that apply.)

Which of the following statements are true when you compare DSCP and IP Precedence to each other? (Choose all that apply.)

A.
DSCP is backwards compatible with IP Precedence.

B.
DSCP cannot be easily mapped into QoS because of its expanded classification options.

C.
DSCP is more granular the IP Precedence, since more marking combinations are available.

D.
DSCP appears stubby when compared IP Precedence, since devices make use of DSCP as defined in RFC exclusively.

E.
DSCP is 6 bits long and IP Precedence is 3 bits long.

F.
DSCP is more restrictive than IP Precedence, since devices are only allowed to use DSCP as defined in RFCs.

Explanation:

A)DSCP is backward compatible with IP Precedence (Class Selector Code point, RFC 1812) but not with the ToS byte definition from RFC 791 (“DTR” bits) Reference: Introduction to IP QoS (Course) p.45
