An engineer is trying to implement BGP configuration on a router. Which configuration error prevents the ASBR from establishing a BGP neighborship to a directly connected BGP speaker?

A. The routing policy is absent for this Cisco IOS XR eBGP instance.

B. The TCP session parameters are not specified.

C. The VPNv4 address family interferes with the BGP IPv4 address family negotiations.

D. The IPv4 address family configuration under neighbor configuration-mode must be removed.

Refer to the exhibit.

An engineer has started to configure a router for OSPF, as shown.

Which configuration must an engineer apply on the network so that area 15 traffic from R5 to R1 will prefer the route through R4?

A. Implement a sham link on the link between R3 and R2 to extend area 0 over area 15.

B. Implement a multiarea adjacency on the link between R2 and R4, with the cost manipulated to make the path through R4 preferred.

C. Place the link between R3 and R5 in a stub area to force traffic to use the route through R4.

D. Increase the cost on the link between R2 and R3 to a value higher than the link between R2 and R4, to influence the path over R3 and R4.

Refer to the exhibit.

An engineer configured BGP summarization on a customer's network. Which route is advertised to BGP peers?

A. 192.0.0.0/16

B. 192168.0.0/16

C. 192.168.1.0/24

D. 192168.0.5/30

Which two steps must a service provider consider when adding multicast support to the existing MPLS L3VPN? (Choose two.)

A. Using SSM for data MDT helps to minimize the number of group addresses needed in the core

B. Using default MDT results in a reduction of multicast routing states in the core

C. All PEs must be configured as RPs inside of each customer VRF to minimize impact of the RPF lookups

D. Bandwidth may be wasted on PEs as a result of only using the default MDT

E. Forwarding customer multicast traffic only via the default MDT optimizes PE utilization

The network team is planning to implement IPv6 on the company's existing IPv4 network infrastructure. The network currently uses IS-IS to share routes between peers. Which task must the team perform so that IS-IS will run in multitopology mode on the updated IPv6 network?

A. Configure the links between the network routers as point-to-point.

B. Configure the network routers to use metric-style wide.

C. Configure the network routers as Level 2 routers.

D. Configure the IS-IS IPv6 metric on the dual-stack links.

While an engineer deploys a new Cisco device to redistribute routes from OSPF to BGP, they notice that not all OSPF routes are getting advertised into BGP. Which action must the engineer perform so that the device allows O, OIA, OE1, and OE2 OSPF routes into other protocols?

A. Configure the device to pass only O and E2 routes through it.

B. Configure the synchronization keyword in the global BGP configuration.

C. Configure the keyword nssa in the redistribution entry.

D. Configure the keywords internal and external in the redistribution entry.

Which core component of MDT describes the data that an MDT-capable device streams to a collector?

A. sensor path

B. encoder

C. transport protocol

D. subscription
