B. multiple customer sites interconnect through a service provider network using customer edge to provider edge connectivity. C. set of sites interconnect privately over the Internet for security. D. set of sites use multiprotocol BGP at the customer site for aggregation.

DRAG DROP - Drag and drop the LDP features from the left onto the descriptions on the right. Select and Place: implicit null label. explicit null label. inbound label binding filtering. entropy label.

Which two protocols work in the control plane of P routers across the MPLS cloud? (Choose two.). A. ECMP. B. LDP. C. RSVP. D. MPLS OAM. E. LSP.

Refer to the exhibit. An engineer has configured DMVPN on a spoke router. What is the WAN IP address of another spoke router within the DMVPN network?. A. 172.18.46.2. B. 172.18.16.2. C. 192.168.1.1. D. 192.168.1.4.

DRAG DROP - Drag and drop the operations from the left onto the locations where the operations are performed on the right. Select and Place: assigns labels to unlabeled packets. performs penultimate hop popping. handles traffic between multiple VPNs. reads the labels and forwards the packet based on the labels.

Which protocol does MPLS use to support traffic engineering?. A. TDP. B. RSVP. C. LDP. D. BGP.

An engineer configured a company's multiple area OSPF Head Office router and Site A Cisco routers with VRF lite. Each site router is connected to a PE router of an MPLS backbone: Head Office & Site A - ip cef ip vrf abc rd 101:101 ! interface FastEthernet0/0 ip vrf forwarding abc ip address 172.16.16.X 255.255.255.252 ! router ospf 1 vrf abc log-adjacency-changes network 172.16.16.0 0.0.0.255 area 1 After finishing both site router configurations, none of the LSA 3, 4, 5, and 7 are installed at Site A router. Which configuration resolves this issue?. A. configure capability vrf-lite on Site A and its connected PE router under router ospf 1 vrf abc. B. configure capability vrf-lite on both PE routers connected to Head Office and Site A routers under router ospf 1 vrf abc. C. configure capability vrf-lite on Head Office and its connected PE router under router ospf 1 abc. D. configure capability vrf-lite on Head Office and Site A routers under router ospf 1 vrf abc.

Refer to the exhibit. The Los Angeles and New York routers are receiving routers from Chicago but not from each other. Which configuration fixes the issue?. A. interface Tunnel1 no ip split-horizon eigrp 111. B. interface Tunnel1 ip next-hop-self eigrp 111. C. interface Tunnel1 tunnel mode ipsec ipv4. D. interface Tunnel1 tunnel protection ipsec profile IPSec-PROFILE.

DRAG DROP - Drag and drop the MPLS VPN device types from the left onto the definitions on the right. Select and Place: Customer (C) device. CE device. PE device. Provider (P) device.
