Refer to the exhibit.

（含图）

A network engineer is implementing multicast Source-A to send a multicast stream for Receiver-A, and multicast Source-B to send a multicast stream for Receiver-B. Router RC forwards the IGMP host a report and leaves messages to IP address 192.168.10.1. How must the multicast features be implemented to prevent RB from receiving multicast flooding from Source-A?

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?

An ISP Is Implementing end-to-end fault monitoring for a customer based on the IEEE 802.3ah standard. The solution must detect when 15 or more corrupted Ethernet packets arrive within 10 ms and stop propagating traffic through the ISP backbone network or to the customer side. Which configuration must the ISP engineer apply?

Refer to the exhibit.

（含图）

A network engineer is implementing an LDP-based MPLS solution to enable packet flow between the two bank sites. The engineer was given two requirements:

✑ LDP peering must stay up when there is a link failure between R3 and R6

LDP peering must not flap when there is a link failure between R5 and R6

Which action meets these requirement?

Refer to the exhibit.

（含图）

ISP ASN 65100 provides Internet services to router CE-1 and receives customer prefix 198.18.18.0/24 via eBGP. An administrator for the ISP is now provisioning RTBH services to provide on-demand data-plane security for the customer's IP space. Which route-map configuration must the administrator apply to router RTBH-1 to complete the implementation of RTBH services to CE-1?

What is a characteristic of MVPN?

Refer to the exhibit.

（含图）

A network support engineer for ASN 65502 receives a technical support ticket from a customer in ASN 65503 who reports that an eBGP session is down. The engineer determines that the peering failed after a recent change to the device at 192.168.26.2. EDGE-GW-1 must establish an eBGP session with the peering router 192.168.26.2. Which configuration establishes this session?

Refer to the exhibit.

（含图）

CE1 and CE2 require connectivity to the internet through the ISP connected to PE3. What should an engineer configure to complete this task?

A network engineer is configuring RIP as the routing protocol between multiple PEs and CEs. The engineer must avoid advertising the same routes back to their sources. Which action should be performed on the routers to accomplish this task?

Refer to the exhibit.

（含图）

A network engineer at a large ISP Is configuring telemetry streams to monitor the health status of PE routers on the network using gRPC dial-out. The PE routers are located at several data centers in different physical locations, and they are using IS-IS and BGP for routing. Which additional configuration must the engineer implement on the PE routers to meet the goal?

Refer to the exhibit.

（含图）

An engineer ran this show telemetry command to view subscription SUB11 on RouterX. The engineer then decided that RouterY should provide the same output for sensor group SGroup13 as RouterX. The engineer cannot access RouterX to copy its configuration No access lists on the router block user access. Which configuration must the engineer apply on RouterY to provide the same output from the show telemetry command?

Which feature describes the adjacency SID?

Refer to the exhibit.

（含图）

A NOC engineer is configuring label-based forwarding from CSR to the EPC gateway. Cell-site operation and maintenance for IPv4 traffic between 10.20.10.1 and 192.168.10.10 is already up. CR1 and CR2 are configured as route reflectors for AG1 and AG2. Which action completes the configuration?

Refer to the exhibit. A network engineer is configuring router RB to secure BGP advertisements against route hijacking activity. RB must validate all prefixes that it receives from origin AS 200 before installing them in the BGP route table. Which configuration meets the requirement?

What occurs when a high bandwidth multicast stream is sent over an MVPN using Cisco hardware?

Refer to the exhibit.

（含图）

A network engineer must configure an LDP neighborship between two newly installed routers that are located in two different offices. Router 1 is the core router in the network and it has already established OSPF adjacency with router 2. On router 1 and router 2. interface fa0/0 is configured for BFD. Which additional configuration must the engineer apply to the two devices to meet the requirement?

Which condition must be met for TI-LFA to protect LDP traffic?

Refer to the exhibit. The CE router is peering with both PE routers and advertising a public prefix to the internet. Routing to and from this prefix will be asymmetric under certain network conditions, but packets must not be discarded. Which configuration must an engineer apply to the two PE routers so that they validate reverse packet forwarding for packets entering their Gi2 interfaces and drop traffic from the RFC1918 space?

An engineer is configuring IEEE 802. 1ad on the access port on a new Cisco router. The access port handles traffic
From multiple customer VLANs, and it is expected to mark allcustomer traffic to the same VLAN without dropping any
Traffic. Which configuration must the engineer apply?

The service provider is serving hosts with two different multicast streams from source X and source Y. Source X is multicast group 224.0.0.0/8, and source Y is multicast group 226.0.0.0/8. Multicast source X should send its stream through bidirectional RP address 10.20.1.1, and multicast source Y should send its stream through RP address 10.20.2.1. Which configuration meets these requirements?
