Q6. An engineer needs to implement changes to Router_A during a maintenance window. The engineer first saves the running-configuration of all routers to the local disk0, then applies the required configuration changes. However, during post checks, the engineer realizes the implementation was deployed on Router_B instead. 

Which command should the engineer apply to reverse the changes made during the maintenance window? 

A. configure revert disk0:myconfig-1 

B. configure reload ditk0:myconfig-1 

C. configure copy disk0:myconfig-1 

D. configure replace disk0:myconfig-1

Q7. 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.
