From a customer's perspective, how does a VPRN service operate?
A VPRN (Virtual Private Routed Network) provides a Layer 3 VPN service over a service provider's network.
Each customer site connects to a PE router.
Sites are connected via a routed network using separate routing instances.
Customer routers see routed connectivity, as if connected to their own private WAN.
Option C is correct -- VPRN provides routed connectivity between sites.

Nokia SRA Guide -- Service Types and Operation
Which of the following is a characteristic of a subnet created with a /31 prefix?
A /31 subnet in IPv4 provides exactly two IP addresses (e.g., 192.168.1.0/31 usable: 192.168.1.0 and 192.168.1.1). Traditionally, these would represent a network address and a broadcast address, but RFC 3021 redefines /31 subnets for point-to-point links, such as router-to-router connections.
In a /31 subnet:
Broadcast address is not used.
Both IPs are treated as usable host addresses.
It's ideal for point-to-point links, saving address space.
This is widely supported and standardized in Nokia IP and routing platforms.

RFC 3021 -- 'Using 31-Bit Prefixes on IPv4 Point-to-Point Links'
Where would you expect to find a P router in a service provider's network?
A P router (Provider router) is located in the core of the service provider's network. Its functions include:
Forwarding MPLS-labeled packets between PE routers.
Not interacting directly with customer routes or routing instances.
Having no knowledge of VPN routing or customer-specific services.
Option C is correct -- P routers sit in the MPLS core, isolated from customer edge.
Nokia MPLS and Services Guide -- Core vs Edge Router Roles
Nokia SRA Study Guide -- 'PE and P Devices in MPLS'
Which of the following statements about VPLS is FALSE?
VPLS (Virtual Private LAN Service) is a Layer 2 VPN service that emulates a bridged Ethernet LAN across an MPLS/IP network.
Learns MAC addresses dynamically from:
SAPs (Service Access Points)
SDPs (Service Distribution Points)
Maintains a Forwarding Database (FDB) per VPLS instance.
For unknown MAC destinations, a VPLS floods the frame to all other sites -- just like a regular Ethernet switch.
Option C is FALSE -- VPLS does NOT discard unknown MACs; it floods them.
Nokia VPLS Services Guide -- Learning and Forwarding
Nokia SRA Study Guide -- VPLS Operation
Which of the following statements about the IP forwarding process on a router is TRUE?
When a router forwards a packet, it performs the following operations:
Looks up the destination IP address in the routing table to determine the next hop or egress interface.
Uses the ARP table to resolve the MAC address of the next-hop IP.
Option A is incorrect -- source IP is not used for route lookup.
Option C is incorrect -- routers don't resolve the source MAC.
Option D is partially true, but routing begins with the routing table, making B the most accurate.
