Ace the Nokia 4A0-104 Exam: Ultimate Preparation Guide

Yes, A routing policy is required to advertise routes between PE routers in a VPRN regardless of the CE-PE routing.

Yes, A routing policy is required in this case because BGP is used as the PE-CE routing protocol.

No, a routing policy is not required. By default, the Alcatel-Lucent 7750 SR will advertise all VPRN routes between PE routers.

No, a routing policy is not required on PE1, but an import policy is required on PE2.

Each VRF table contains routes for a single VPRN.

Route targets are used to determine if a prefix belongs to a VRF.

Routes in the VRF table are advertised to the core routers.

VPN labels identify which VRF table should be used for a packet.

MP-BGP in the provider network needs to support the VPN-IPv6 address family.

PE routers must be configured to run MP-BGP.

PE-to-CE BGP sessions need to be configured to support IPv6.

The provider network core must be configured to support IPv6.

The labels are of local significance only, so other routers can use the same value.

10.10.10.1 has yet to send its own unique label.

Router R4 is using the same tunnel to send and receive to 10.10.10.1.

The service on 10.10.10.1 is down, so it is rejecting packets.

LDP

BGP

MP-BGP

MPLS

6VPE is a tunneling technology that makes use of MPLS tunnels to transport IPv6 prefixes over an IPv4 infrastructure.

Customers connected to 6VPE can run IPv6 or IPv4.

On a PE router, if the MP-BGP next hop is an IPv4 address, a mapped IPv6-compliant address will be used.

6VPE implements its own VPN-IPv6 address family and is a replacement for MP-BGP.

A VPLS service does not use an FDB.

The router reads the destination MAC address of packets passing through the service.

The router reads the source MAC address of packets passing through the service.

The router uses reverse ARP (RARP) to resolve the MAC addresses for unknown destinations.

The router is programmed with MAC addresses by the network administrator.

iocal-sdp' and 'remote-sdp' indicate that all services using these SDPs are pinged.

'Iocal-sdp' and remote-sdp' indicate that pings are initiated from both local and remote routers.

Both 'Iocal-sdp' and 'remote-sdp' take parameters to specify which SDPs are used for the test.

'Iocal-sdp' indicates that the ping is sent in-band, and remote-sdp' indicates the return ping is in-band.

Spoke SDPs prevent loops in a VPLS.

Mesh SDPs and spoke SDPs can be used in the same VPLS.

A spoke SDP does not require the routers at both ends to be directly connected.

A mesh SDP is identical to a spoke SDP except for its flooding behavior.

The default service MTU on a VPLS service is 1514 bytes.

The default IP MTU of an IES is set based on the network port MTU.

During VC label signaling, the VC MTU is verified and must match.

All of the above.
