MEF CECP EXAM QUESTIONS WITH
100% CORRECT ANSWERS!!
1 of 28
Definition
-RDI is analogous to RDI found in traditional TDM/SONET
networks
-RDI is signaled between peer MEPS to indicate a network
fault
- Connectivity Check Messages (CCM) must be enabled in
order to detect the fault
- When a MEP detects a CCM fault, the RDI bit is set in the
CCM
message in the opposite direction

Definition
Point-to-point Ethernet links are carried over SDH/SONET
networks, making use of virtual concatenation and LCAS
(Link Capacity
Adjustment Scheme) to create an appropriate size carrier
bundle, of
the Generic Framing Procedure of SDH equipment, and
takes advantage of the management and recovery features
of SDH to provide high availability and resilience to failures.

- Analogous to ICMP Ping
- Loopback message/Loopback response is used
for fault isolation/detection, not performance/SLA
verification
- Each MEP & MIP can be uniquely addressed and
individually tested Unicast frames that a MEP transmits,
they are similar in concept to an Internet Control Message
Protocol (ICMP) Echo (Ping) messages,
sending Loopback to successive MIPs can determine the
location of a fault. Sending a high volume of Loopback
Messages can test bandwidth, reliability, or jitter of a
service, which is similar to flood ping. A MEP can send a
Loopback to any MEP or MIP in the service. Unlike CCMs,
Loop back messages are administratively initiated and
stopped. *used to discover the MAC addresses of
remote MEPs*
