Which BGP feature causes to replace the AS number of originating router with the AS number of the sending router?

• route reflectors
• route dampening
• confederations
• AS override

The network engineering group of a large ISP needs to harden the management plane of its Cisco 9000Series ASRs. While addressing IPv6 ICMP issues, they realized they have to limit the rate at which IPv6 ICMP error messages are sent out on the network. Which command do they need to apply?

• icmp ipv6 rate-limit unreachable 1000
• ipv6 rate-limit 1000
• icmp ipv4 rate-limit unreachable 1000
• ipv6 icmp error-interval 50 20

You are writing the requirements for an MPLS L3VPN environment that uses MP-BGP between PE routers. In this environment, route targets and route distinguishers need to be advertised between the PE routers.Which three operations meet these requirements? (Choose three.)

• mandatory creation of PE-to-PE BGP sessions between the outgoing interface IP addresses
• advertisement of standard communities, enabled on the PE-to-PE BGP neighbors
• creation of PE-to-PE BGP sessions between loopback IP addresses
• full mesh of IBGP sessions
• full mesh of EBGP sessions and partial mesh of IBGP sessions
• advertisement of extended communities, enabled on the PE-to-PE BGP neighbors

An engineer is troubleshooting AToM on an IOS XE router and receives an error when creating the xconnect. Which command does he need to complete to create the xconnect in AToM?

• encapsulation mpls
• encapsulation 12tpv3
• protocol 12tpv3
• protocol none

An engineer is investigating an MPLS LDP issue. Which command should an engineer use on a Cisco IOS XE device to display the contents of the LFIB?

• show mpls forwarding-table
• show mpls ldp neighbors
• show mpls ldp labels
• show mpls ldp bindings

What is a requirement to share VRF reachability information to all members of a VPN when using IPv6?

• PE and CE routers must be running BGP as the PE-CE routing protocol
• PE routers must have MPLS disabled and be running MP-BGP between all P and PE routers.
• PE routers must be running MP-BGP and bgp default ipv4-unicast must be disabled
• All PEs must have the same VRFs configured.

Which two statements about MPLS L3 VPN RDs are true? (Choose two.)

• They enable EIGRP to use address families to separate traffic between IPv4 and VPNv4.
• They are represented as 32-bit values
• They are represented as 64-bit values.
• They enable OSPF to import and export routes into the global routing table of a router.
• They allow BGP to uniquely identify duplicate routes.

An engineer needs to improve MPLS network management by implementing a set of tools to support the NOC engineers in troubleshooting network failures. Which feature should the engineer implement to check the connectivity of the MPLS LSP between the ingress and egress PE routers?

• MPLS OAM
• MPLS-TP
• LDP autodiscovery
• extended ping

The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?

• L2VPN with the broadcast traffic processed at the ingress PE.
• L3VPN with direct LSP connectivity between all PEs.
• L2VPN by encapsulating multiple frame formats with interworking.
• L3VPN using a hierarchical topology of N-PEs and U-PEs.

In an Ethernet Virtual Circuit environment, which restriction do bridge domains have when STP is running?

• The STP mode must be RSTP or PVST+
• Bridge domains must be mapped to a different VLAN.
• The STP mode must be MSTP
• Bridge domains must belong to different MST instances.
