A service provider is using multicast flows to provide streaming video content to its customers. Video streams are sometimes interrupted, and network instability is determined to be the cause. Which action should the service provider take to decrease the burden on the router resources in an unstable unicast routing environment?
A. increase the PIM hello hold timers
B. reduce the volume of query messages
C. filter unnecessary SA messages
D. tune the RPF backoff
Refer to the exhibit.

Router 1 is missing the route for the router 2 loopback 0. What should the engineer change to fix the problem?
A. the area numbers on Router 1 and Router 2 to be similar
B. the wildcard mask network statement in OSPF of Router 2
C. Router 1 to be an ABR
D. the hello timers on Router 1 and Router 2 to be different

AN engineer is configuring segment routing on an ISP to simplify traffic engineering and management across network domains. What should the engineer do to complete the implementation of segment routing?
A. OSPF must be configured with wide area metrics to support routing.
B. The segment will run without any further configuration.
C. Area authentication must be enable before segment routing will run.
D. Area Authentication must be enable before segment routing will run.
A network engineer is testing an automation platform that interacts with Cisco networking devices via NETCONF over SSH. In accordance with internal security requirements:
