Exam 39: Implementing and Operating Cisco Data Center Core Technologies (DCCOR)

Refer to the exhibits. R1 and R2 are directly connected and IS-IS routing has been enabled between R1 and R2. R1 generates the above log message periodically. Based on this output, which statement is true?

You are configuring MPLS traffic-engineering tunnels in the core. Which two ways exist for the tunnel path across the core? (Choose two.)

A regional MPLS VPN provider operates in two regions and wants to provide MPLS L3VPN service for a customer with two sites in these separate locations. The VPN provider approaches another organization to provide backbone carrier services so that the provider can connect to these two locations. Which statement about this scenario is true?

Refer to the exhibit. This configuration is being applied on an IOS XR route. Which statement about this configuration is true?

Refer to the exhibit. Which three outcomes occur if the prefix list is added to the neighbor? (Choose three.)

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?

An engineer is setting up overlapping VPNs to allow VRF ABC and XYZ to communicate with VRF CENTRAL but wants to make sure that VRF ABC and XYZ cannot communicate. Which configuration accomplishes these objectives?

Which configuration modifies Local Packet Transport Services hardware policies?

Refer to the exhibit. R101 is peering with R102 and R103, and R201 is peering with R202 and R203 using iBGP Labeled Unicast address families. The OSPF area 0 border routers are in a full iBGP Labeled Unicast mesh, and VPNv4 routes are exchanged directly between PE routers R101 and R201 through iBGP. Which address family-level configuration must be applied on ABR R102 on ABR R102 to support a Unified MPLS routing architecture with partitioned IGP domains?

Which configuration mode do you use to apply the mpls ldp graceful-restart command in IOS XE Software?

Refer to the exhibit. With which router does IOSXRV-1 have LDP session protection capability enabled but session hold up is not active?

A network engineer must enable the helper router to terminate the OSPF graceful restart process if it detects any changes in the LSA. Which command enables this feature?

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

An engineer needs to implement QOS mechanism on customer's network as some applications going over the Internet are slower than others. Which two actions must the engineer perform when implementing traffic shaping on the network in order to accomplish this task? (Choose two.)

BGP has been implemented on an IOS XR router. Which configuration sends BGP IPv4 labels to build inter-domain LSPs?

Refer to the exhibit. An engineer is updating this network to meet these conditions: Area 10 will receive inter-area routes and support mutual redistribution of external routes with the extranet. The ::/0 route is prohibited in Area 10. Area 11 will receive only the ::/0 route from the ABR. External route redistribution is not supported in Area 11. The ABR in Area 11 will advertise no interarea routes. Which two configurations must be performed to meet the requirements? (Choose two.)
