Q42. Given the diagram shown, and the following information: 

. Configured on CSA1 and the two MLS routers is redundant ePipe 10 

. Interchassis Backup Pseudowires (ICB-PW) provide a path of last resort to the Customer Edge (CE) Service Access Points (SAPs) 

. A Multichassis Link Aggregation Group (MC-LAG) protects the CE access ports 

. Assume normal status on all ePipe 10 spoke Service Distribution Points (SDPs) If the CSA1 primary spoke SDP fails, which three statements correctly describe the resulting status of the MLS2 ePipe 10 endpoint objects? (Choose three) 

A. SAP LAG-2 active 

B. SAP LAG-2 standby 

C. Spoke SDP 3:10 active D. Spoke SDP 3:10 standby E. Spoke SDP 3:100 active 

F. Spoke SDP 3:100 standby 

Answer: B, D, E 


Q43. Given the show command results shown: 

With what IEEE 1588v2/Precision Time Protocol (PTP) v2 message did the slave node set the Unicast message rates used by the master? 

A. Announce granted 

B. Announce request 

C. Sync granted 

D. Sync request 

Answer: B 


Q44. 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? 

A. Setthe PTP porttothe desired ITU-T G.781 Option 1 or2 mode 

B. Setthe SROS IEEE 1588v2 profile to IEEE 1588-2008 

C. Set the SROS IEEE 1588v2 profile to ITU-T G.8265.1 

D. Configure ql-override on the PTP reference entry 

Answer: C 

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) - PRS 

. Reference 2 receives QL - DUS 

. BITS sets QL-STU 


Q45. Considering the configuration shown, and given the following conditions: 

* The 7705 Service Access Router (SAR) is a Precision Time Protocol (PTP) v2 master on domain 1 

* It is configured for the ITU-T G.8265.1 profile 

* ref1 is an Extended Superframe (ESF) DS1 and is qualified 

* The DS1 source indicates in its SSM messages that it is synchronized to a Stratum 3 clock 

* ref2 is a Synchronous Ethernet (SyncE) port and traces its source to a Stratum 1 reference Which Quality Level will the 7705 SAR master announce to its slave routers? 

A. QL-DUS 

B. QL-EEC2 

C. QL-STU 

D. QL-PRS 

Answer: D 


Q46. Given the show command results and the configuration shown: 

Why did the head end router choose to protect the Label Switch Patti (LSP) with a dynamic bypass tunnel instead of the manual bypass tunnel as configured? 

A. Manual bypass tunnels must be configured for fast reroute facility and cspf 

B. The bypass tunnel path's first hop must avoid the protected LSP tail end 

C. The protected LSP needs a strict hop path to the tail end router 

D. The routers choose dynamic bypass tunnels over manual bypass tunnels by default 

Answer: B 


Q47. How does a Multilink Point-to-Point (ML-PPP) endpoint indicate its desire to implement the Multilink Protocol (MP)? 

A. It sends an endpoint discriminator during the Internet Protocol-Control Protocol (IPCP) negotiations 

B. It sets the Short Sequence Number (SSN) flag in its Link Control Protocol (LCP) messages 

C. It sets the Maximum Received Reconstructed Unit (MRRU) option in its link LCP messages 

D. It sends protocol identifier 0x003d (MP) in its Network Control Protocol (NCP) messages 

Answer: C 


Q48. With which message type does an IEEE l583v2/Precision Time Protocol (PTP) v2 slave announce itself on the network? 

A. Sync_Request 

B. Announce_Request 

C. Announce 

D. Delay_Request 

Answer: B
