OC 255 - 13.21 Gbps

Question 21

MPLS operation modes

Answer 21

Cell Mode - ATM
Frame mode - Ethernet

Question 22

OSPF natively supports IPv6 SR

Answer 22

False, ISIS does

Question 23

OC4 signal is equivalent to an STM1

Answer 23

False, an OC3

Question 24

Sonet is more used in the USA, SDH in Europe

Answer 24

True

Question 25

CES is typically used to transmit voice and video over MPLS

Answer 25

False, CES is transported over ATM networks

Question 26

TDMoIP is a transport technology optimized for carrying E1/T1, E3/T3 trunks and multi-line serial data over packet-switched networks (PSNs)

Answer 26

True

Question 27

IPoDWDM is a technology that integrates Routers into DWDM

Answer 27

False, the opposite. In practice, it transfers the transponder function to a router card, so there is no need for optical to electrical to optical conversion in a DWDM system transponder.
In summary: The Router operates as a transponder
