Nokia Nokia Virtual Private Routed Networks 4A0-106 Exam Dumps: Updated Questions & Answers (July 2025)

Traditional BGP loop detection mechanisms may detect a loop in the VPRN scenario, which in fact is not present.

The Nokia 7750 SR accepts routes containing AS_PATH loops by default.

When the CLI command "config>router>bgp# loop-detect discard-route" is used, the Nokia 7750 SR sends a notification to the remote peer and drops the BGP session.

In VPRN implementations where the CE-PE protocol is BGP, it is possible for separate sites of the same customer to use the same BGP autonomous system number.

ample Policy should be applied as an export policy on the PE connected to the main site of Customer 1

ample Policy 3 should be applied as an export policy on the PE connected to the main site of Customer 2

ample Policy 3 should be applied as an export policy on both PEs connected to the main site of Customer 1 and the main site of Customer 2

ample Policy should be applied as an export policy on both PEs connected to the main site of Customer 1 and the main site of Customer 2

ample Policy should be applied as an export policy on all PEs connected to sites of Customer 1

The policy should be applied as an import policy on the PE connected to the main site of Customer 1.

The policy should be applied as an import policy on all the PEs connected to the sites of Customer 1.

The policy should be applied as an export policy on the PE connected to the main site of Customer 1.

The policy should be applied as an export policy on all the PEs connected to the sites of Customer 1.

Memory exhaustion in the provider core

Route leaking between the customer networks

CPU utilization for route processing

Unwanted packet forwarding between customer networks

The protocol is configured under the config>service context

The protocol is configured under the global router context

The interface leading to the PE is defined as a protocol neighbor

The routing protocol used must be the same as the routing protocol used at other CE-PE locations in the same VPN.

A routing policy may or may not be required depending on the routing requirements and routing protocol

Allow routes to be exchanged between all or selected sites of one VPRN and all or selected sites of a second VPRN

Allow the service provider to provide multiple VPRNs with Internet access

Reduce the number of VPRN tunnels required

Simplify the administration of multiple VPRNs

Force all traffic in multiple VPRNs to pass through a single device

Static

RIP

OSPF

IS-IS

The Nokia 7750 SR allows the setting of the maximum number of routes that can be accepted in a VRF for a VPRN service.

The "maximum-routes" command is used to specify the maximum number of remote routes that can be held within a VRF for a VPRN service.

When the "maximum-routes" command is used with the "log-only" parameter, new routes are still learned.

Once the "threshold" value is reached, no new routes are added to the VRF.
