4A0-M01 - Alcatel-Lucent IP/MPLS Mobile Backhaul Transport Exam
Go back to
Which statement correctly describes Virtual Routing and Redundancy Protocol (VRRP) configuration?
The router assigns priority 100 to a non-owner VRRP interface by default
In the Alcatel-Lucent SROS, which command creates the OC-3 path's Administrative Unit (AU)- 4 Virtual Container (VC) capacity?
configure port 3/1/2 sonet-sdh path sts3
Which statement best describes phase synchronization as it is used in the backhaul transport?
The master and slave clockframes start within +/- 500 nanoseconds
Which synchronization technique supports time of day and phase synchronization?
IEEE 1588 v2/Precision Time Protocol (PTP)v2
An SROS router obtains its timing exclusively from its BITS input port. The router sets Quality Level (QL) SONET Traceability Unknown (STU) on this Superframe (SF) framed DS1 BITS reference. What must you configure on this master router to pass the best clock quality level to the downstream Synchronous Ethernet (SyncE) slave nodes while maintaining traceability to the DS1 source?
Enable "ql-override prs" on the BITS reference
When researching carrier-class Ethernet standards to support the mobile backhaul Ethernet transport, which standards body would you consult?
Which messages, periodically sent between an IEEE 1588v2/Precision Time Protocol (PTP) v2 master and slave, serve as hellos to help the slave choose the best available master?
Which statement correctly describes a Versatile Service Module (VSM) Layer 2 and Layer 3 service cross-connect's operation?
A CCAG may rate limit the A or B path all the way up to the maximum CCAG available bandwidth
Which is a characteristic of the IEEE 802.3 Slow Protocol?
There are a maximum of 10 frames transmitted per second
Which statement best describes adaptive timing techniques?
Adaptive timing calculates the time of day from time stamped packets
Which component must you configure on an IEEE 1588v2/Precision Time Protocol (PTP) v2 slave to enable it to choose its master based on Synchronization Status Message (SSM) Option 1 or Option 2 Quality Levels?
Set the SROS IEEE 1588v2 profile to ITU-T G.8265.1
Which statement correctly describes the Point-to-Point (PPP) Multilink Protocol (MP) negotiation process?
At least one link must complete Link Control Protocol (LCP) negotiations before the bundle can initialize
The IETF is know for which standardization effort?
It maintains Requests for Comment (RFC) that describe technical solutions to Internet challenges
Which timing technique can deliver time of day and phase synchronization information to the base station without concern for Packet Delay Variation (PDV)?
Global Positioning System (GPS)
In the Alcatel-Lucent SROS, which payload type set in a SDH-framed OC-12 port creates individual E1 containers?
If an IEEE 1588v2/Precision Time Protocol (PTP) v2 slave times out announce messages with the master, to which state does the slave port transition to choose another potential master?
Which command example correctly configures a 7750 Service Router (SR) for Synchronous Ethernet (SyncE) support?
configure card 1 mda 1 sync-e
