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

Refer to the exhibit.

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:

1.

NETCONF sessions are permitted only from trusted sources in the 172.16.20.0/24 subnet.

2.

CLI SSH access is permitted from any source.

Which configuration must the engineer apply on R1?

A. configure terminalhostname R1 ip domain-name mydomain.comcrypto key generate rsaip ssh version 1access-list 1 permit 172.16.20.0 0.0.0.255netconf ssh acl 1 line vty 0 4transport input sshend

An engineer at ISP C is configuring a new interconnection with ISPs A and B using the BGP protocol. After the initial configuration, the engineer noticed high memory usage and an abnormally large LIB table on router R2. Which two actions must the engineer take on R2 to minimize memory usage? (Choose two.)

A. Configure the mpls ldp neighbor 11.11.11.11 labels accept 1 command.

B. Configure Standard ACL 1 with accepted prefixes.

C. Configure Extended ACL 101 with accepted prefixes.

D. Configure the mpls ldp neighbor 1.1.1.1 labels accept 101 command.

E. Configure the mpls ldp neighbor 21.21.21.21 labels accept 101 command.

Refer to the exhibit. An engineer working for a service provider with an employee ID: 1234:56:789 notices that malicious traffic with a source IP in the RFC1918 range is arriving on the WAN connection to the internet and impacting customer resources on the LAN.
