Referring to the topology diagram show in the exhibit, which three statements are correct regarding the BGP routing updates? (Choose three.)

• A.The EBGP routing updates received by R3 from R6 will be propagated to the R2 and R4 routers
• B.The IBGP routing updates received by R3 from R2 will be propagated to the R6 router
• C.The IBGP routing updates received by R1 from R4 will be propagated to the R5, R7, and R2 routers
• D.The EBGP routing updates received by R1 from R5 will be propagated to the R2 and R4 routers
• E.The EBGP routing updates received by R1 from R5 will be propagated to the R2, R4, and R7 routers
• F.The IBGP routing updates received by R2 from R1 will be propagated to the R3 router

Which two conditions must be met before separate ISPs can provide interdomain multicast routing? (Choose two.)

• A.Each ISP must replace its RP assignment with a global RP.
• B.Each ISP must configure MSDP to connect its individual multicast administrative domain to the domains at other ISPs.
• C.Each ISP must dedicate a single router to handle multicast traffic between providers.
• D.Each ISP must support intradomain multicast routing.
• E.Each ISP must configure its network to use PIM-DM.

Refer to the exhibit. After maintenance to activate BGP neighbors connecting a new data center attached to R1, L3VPN customers attached to OSPF domain 100 lost connectivity to services in OSPF 200 and OSPF 300. However, Unified MPLS services within OSPF 100 remain reachable.
Which action must the network engineer take to resolve the outage?

• A.Raise the maximum prefix limit on R2 to 1560 or more
• B.Reset the BGP session between R1 and R2
• C.Establish new MPLS LSPs from R1 to R2, R3 and R4
• D.Activate BGP neighbors between the new data center and R2 and R3

What is the difference between basic IS-IS and OSPF packet types?

• A.IS-IS and OSPF use link-state update packets, but only OSPF uses link-state ACK packets.
• B.IS-IS and OSPF use area packets, but only IS-IS uses sequence number packets.
• C.IS-IS and OSPF use link-state update packets, but only IS-IS uses DBD packets.
• D.IS-IS and OSPF use Hello packets, but only OSPF uses DBD packets.

SIMULATION
Guidelines
This is a lab item in which tasks will be performed on virtual devices.
- Refer to the Tasks tab to view the tasks for this lab item.
- Refer to the Topology tab to access the device console(s) and perform the tasks.
- Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.
- All necessary pre-configurations have been applied.
- Do not change the enable password or hostname for any device.
- Save your configurations to NVRAM before moving to the next item.
- Click Next at the bottom of the screen to submit this lab and move to the next question.
- When Next is clicked, the lab closes and cannot be reopened.
Topology

Tasks
R21 through R25 are routers that perform MPLS label-forwarding operations. Candidates are required to perform the below configuration and verification tasks as noted.
1. Configure R22 and R23 to discover each other as LDP-speaking routers on the connected link.
2. Ensure the logical interface is selected as the persistent identifier on both R22 and R23.
3. Modify R21 and R25 to enable the MPLS-TE tunnel to be signaled and up between them.
Initial configuration with IP addressing has been completed.
The candidate must not make any changes to the configurations except to fulfill the tasks listed above. Only use the provided logical interface for the applicable task.
*The candidates have console access to all the routers R21, R22, R23, R24 and R 25.
