Answer: C
Q82. Given the diagram and the following information:
. Virtual Private Routed Network (VPRN) 5 spans the routers Point of Concentration (POC) 3-1 and 3-2 and the Multilevel Switch (MLS) routers MLS1 and MLS2
. Multiprotocol Border Gateway Protocol (MP-BGP) is configured and operational
. Pseudowire status is signaled, as shown, on the ePipe/VPRN spoke Service Distribution Points (SDPs)
. Spoke SDP 1:50 has failed and recovered
What command verifies that the two CSA router pseudowires are operational?
A. show service id 50 active
B. show service id 50 endpoint
C. show service id 50 revert-time
D. show service id 50 sdp
Answer: B
Q83. Consider the topology and MLS1 configuration shown, and given the following conditions:
. MLS1 delivers the PRC traceable clock to the network
. Reference 1 receives Quality Level (QL)- EEC-1
. Reference 2 receives QL - DNU
.BITS is operational
What quality level will MLS1 deliver to POC2-1 on its Synchronous Ethernet (SyncE) port 1/2/7?
A. QL-DNU
B. QL-EEC1
C. QL-PRC
D. GL-SSU-A
Answer: D
Q84. Which statement is true concerning aPipe ATM cell mode versus ATM Adaptation Layer (AAL) 5 Service Data Unit (SDU) frame mode?
A. AAL5 SDU frame mode supports ATM cell concatenation
B. ATM cell mode can bind multiple virtual circuits to a single service
C. AAL5 SDU frame mode passes the cell header with the payload
D. ATM cell mode requires a control word for cell reordering
Answer: B
Q85. Choose the two SAP identifiers that a Cross Connect ID (CCID) can bind to create a bi-directional Layer 2 and Layer 3 service cross connect. (Choose two.)
A. sap 1/1/9:100:200
B. sap 1/1/8:100:200
C. sapccag-l.a:l00
D. sapccag-2.a:100
E. sapccag-1.b:100
F. sap ccag-2.b:200
Answer: C, E
Q86. As which clock type must an IEEE 1588v2 node operate in order to slave to the Primary Reference Clock (PRC) and serve as a master to downstream nodes?
A. Boundary
B. Ordinary Master
C. Ordinary Slave
D. Peer-to-peer transparent clock
E. End-to-end transparent clock
Answer: A
Q87. Click on the exhibit Given the diagram and the following information:
. Virtual Private Routed Network (VPRN) 5 spans the routers Point of Concentration
(POC) 3-1 and 3-2 and the Multilevel Switch (MLS) routers MLS1 and MLS2
. Multiprotocol Border Gateway Protocol (MP-BGP) is configured and operational
. Pseudowire status is signaled, as shown, on the ePipe/VPRN spoke Service Distribution Points (SDPs)
In the exhibit, how does the signaled pseudowire status affect the VPRN 5 service?
A. The spoke SDP 1:50 status 0x00 keeps the POC3-1 VPRN interface "to NodeB" operationally down
B. The spoke SDP 2:50 status 0x20 holds down the POC3-2 static routes until SDP 2 recovers
C. MLS1 and MLS2 route traffic targeting the NodeB loopback interface through router POC3-1
D. MLS1 and MLS2 route traffic targeting the NodeB loopback interface through router POC3-2
Answer: C
Q88. Click on the exhibit Given the diagram and the following information:
. Virtual Private Routed Network (VPRN) 5 spans the routers Point of Concentration (POC) 3-1 and 3-2 and the Multilevel Switch (MLS) routers MLS1 and MLS2
. Multiprotocol Border Gateway Protocol (MP-BGP) is configured and operational
. Pseudowire status is signaled, as shown, on the ePipe/VPRN spoke Service Distribution Points (SDPs)
What might you configure on the services illustrated to hold down the primary VPRN NodeB loopback interface static route in case of an intermittent or rapid spoke SDP failure and recovery?
A. Set port hold down timers on the CSA to POC3-1 link
B. Configure Label Distribution Protocol (LDP) Sync on the VPRN static routes
C. Enable BGP next-hop tracking in the VPRN BGP peer groups
D. SetareverttimervalueontheCSAePipe50endpoint
Answer: A
