Q4. Refer to the exhibit. 

A service provider is running MPLS TE across its network. IS-IS is deployed as the IGP for the ISP network. The MPLS TE tunnel 0 configured on PE2 is seen in an operational down state. PE2 is a level-1 router and the destination 192.168.1.1 is located in the IS-IS level-2 area. Which action is required to bring the MPLS TE tunnel 0 to up state? 

A. Configure the next-address entries as loose paths in the explicit-path. 

B. Change the autoroute option from destination to announce. 

C. Configure a bandwidth value for the tunnel. 

D. Configure an IPv4 address for the Tunnel 0. 

E. Add a dynamic path option to the tunnel.

Q5. A Service Provider is designing control policies at the customer edge of the network, in order to prevent usage that exceeds the contracted terms. A new client that is contracted for only 2 Gbps is connecting to the Service Provider edge with a 10 Gbps interface. Which two QoS strategies meet the design goal? (Choose two.) 

A. On the service Provider edge, enable traffic shaping on the customer port. 

B. On the customer edge device, enable traffic shaping on the interface that is connected to the Service Provider. 

C. On the customer edge device, enable policing on the interface that is connected to the Service Provider. 

D. On the service Provider edge, enable policing on the customer port. 

E. On the service Provider edge, enable WRED on the customer port. 

F. On the customer edge, enable WRED on the interface that is connected to the Service Provider.

Q6. Refer to the exhibit. 

Two ISPs have decided to implement MPLS Inter-AS TE. All routers have full reachability to all subnets. RSVP and MPLS TE have been enabled in all routers interfaces in both ISPs, yet Tunnel 14 is not up Which configuration will fix this issue? 

A. On R1, apply the command: 

interface Tunnel14

B. On R1, apply the command: 

interface Tunnel14 

mpls traffic-eng passive-interface nbr-te-id 10.10.10.4 nbr-igp-id isis 10.0000.0000.0004.00 

C. On R1. apply the command: 

interface Tunnel 14 

tunnel mpls traffic-eng path-option 1 dynamic

Q7. Which are the two fundamental ways in which IEEE 1588 differs from SyncE? (Choose two.) 

A. In addition to frequency synchronization, it achieves ToD synchronization to achieve phase alignment which is required for multi-channel communication. 

B. It is a purely-based solution, with the actual clock values being passed inside the payloads of special packets dedicated to that task. 

C. It offers two major changes over traditional Ethernet to make it suitable for clock distribution: a mandated clock accuracy and the ESMC protocol for clock selection, distribution, management, traceability, and failover. 

D. SyncE is a Cisco proprietary ToD technology where IEEE 1588 is a industry standard recommended for interoperability across vendor devices. 

E. IEEE 1588 applies to voice-only systems or with low-bandwidth data traffic.
