An engineer is configuring two routers to support MPLS LDP sessions between them. The R1 configuration is complete, and work has started on R2 as shown. Which additional configuration must the engineer apply to R2 to complete the task?

Refer to the exhibit:

R1 and R2 are directly connected with Fast Ethernet interfaces and have the above configuration applied OSPF adjacency is not formed. When the debug ip ospf hello command is issued on R1. these log messages are seen.

Which command can be configured on routers R1 and R2 on fO/O interfaces to form OSPF adjacency?

Refer to the exhibit.

A network operator working for a telecommunication company with an employee ID: 4350:47:853 must implement an IGP solution based on these requirements:
* Subnet 10.50.10.0 traffic must exit through the R1 router to connect with the Syslog server.
* Subnet 10.50.20.0 traffic must exit through the R2 router to connect with the NTP server.
* In case of link failure between R2 and R4, traffic must be routed via R1 and R3.
Which two configurations must be implemented on R5 to meet these requirements? (Choose two.)

An engineer is moving all of an organization's Cisco IOS XE BGP routers to the address-family identifier format. Which command should be used to perform this upgrade quickly with the minimum service disruption?

Refer to the exhibit.

An engineer with an employee 10:4350:47:853 is implementing IS-IS as the new routing protocol in the network. All routers in the network operate as Level 2 routers in the same private autonomous system, and the three branches are connected via dark fibre. The engineer has already implemented IS-IS on router R1 with NET address 49.0133.532b.ca14.6915.21311.F40F.1B3a.ba10.00. Which IS-IS NET address configuration must be implemented on R3 to establish IS-IS connectivity?
