Which of the following statements about VXLAN encapsulation is TRUE?
Correct Answer:
D
Explanation
BGP import policies on the Nokia 7750 SR control which routes the router accepts from its peers. When a policy statement is configured to reject routes matching specific prefix lists, those routes are filtered out during the import process. List-1 and List-2 define the prefixes to be rejected. Routes matching either list are dropped and not added to the routing table. Other routes not matching these lists would be accepted based on the policy's default action or remaining statements.
Given the network shown, which of the following is the correct BGP configuration for RR1?
A.
B.
C.
D.
Correct Answer:
D
Explanation
System addresses serve as the loopback interface addresses on routers and provide a stable endpoint for iBGP sessions. Unlike physical interface addresses that can change if interfaces go down, system addresses remain available as long as the router is operational. Using system addresses ensures that iBGP sessions survive interface failures and topology changes. This is considered best practice because it improves session stability and simplifies network management.
Which of the following statements about router reflectors is FALSE?
Correct Answer:
A
Explanation
The CLUSTER_LIST attribute is used by route reflectors to prevent routing loops in iBGP networks. When a route reflector advertises a route back to a client in the same cluster, it adds its cluster ID to the CLUSTER_LIST. If a route with the route reflector's cluster ID in the CLUSTER_LIST is received from another peer, the route reflector rejects it because it originated from its own cluster. This mechanism prevents routes from circulating back to their source.
Which of the following statements about Route Distinguishers (RD) is FALSE?
Correct Answer:
D
Explanation
iBGP peers do not need to be directly adjacent to each other. The iBGP peering requirement is that peers must have an IP route to reach each other, but this can happen through other routers. eBGP peers typically must be directly adjacent as they connect different autonomous systems. The statement that iBGP peers must be adjacent is false. Many iBGP deployments use loopback addresses for peering, which are multiple hops away.
A router in AS 65100 receives three routes for 138.120.0.0/16. The first route has an AS Path of 65200 65400 65300 and a local preference of 150. The second route has an AS Path of 65200 65300 and a local preference of 100. The third route has an AS Path of 65600 65300 and a local preference of 100. Which route will appear in the RIB-out?
Correct Answer:
A
Explanation
This question requires understanding multi-protocol BGP and IPv6 address families. Router A needs specific configuration to enable BGP to exchange IPv6 traffic with router B, which then routes to router D. The correct answer involves enabling the appropriate address family in BGP and configuring IPv6 routes or protocols. Without seeing the exhibit options, option A is identified as the correct configuration needed for IPv6 traffic exchange across the BGP network.
Which of the following statements about IPv6 Link-Local addresses is FALSE?
Correct Answer:
D
Explanation
BGP supports multiple address families including IPv4 unicast, IPv6 unicast, VPN-IPv4, VPN-IPv6, and other variants. Label-IPv4 is not a standard address family designation in BGP. Label-based routing is handled through MPLS label distribution protocols rather than as a distinct BGP address family. While BGP can carry label information within certain address families, Label-IPv4 itself is not a recognized address family that you configure in BGP.

Domain 1: Module 1 – Border Gateway Protocol Fundamentals
Covers BGP overview, BGP peering sessions, BGP route updates and path attributes, and basic route policies. This foundation module introduces the core concepts needed for configuring and managing BGP in service provider networks.
Sample questions from this domain above:
Q1Q2Q4
Domain 2: Module 2 – Multi-protocol BGP
Explores multi-protocol BGP extensions including IPv6 networks, Layer-3 VPN services with VPN-IPv4 and VPN-IPv6 addresses, inter-region transport tunnels with label-IPv4 and label-IPv6 addresses, VXLAN tunnels, and EVPN services. This module demonstrates how to extend BGP beyond standard IPv4 routing.
Sample questions from this domain above:
Q5Q6
Domain 3: Module 3 – BGP route reflectors
Addresses improving iBGP scalability through route reflector design and operation, including cluster topology, loop avoidance mechanisms, and redundancy strategies. Route reflectors are essential for managing large internal BGP deployments efficiently.

FAQ
4A0-114 Exam FAQ
Common questions about the exam itself
What background do I need before taking the 4A0-114 exam?
There are no mandatory prerequisites, but you should have solid knowledge of networking fundamentals and TCP/IP concepts. Practical experience with BGP routing, familiarity with OSPF or IS-IS, and hands-on time with Nokia service routers will strengthen your preparation.
How hard is the 4A0-114 exam and how long should I study?
This is an intermediate-level exam that requires understanding both BGP theory and its application in service provider networks. Most candidates need 4 to 8 weeks of structured preparation combining instructor-led training with hands-on lab practice to build confidence.
Which Module in 4A0-114 do candidates typically struggle with most?
Module 2 on Multi-protocol BGP is often the most challenging because it requires mastering multiple address families, EVPN concepts, and MPLS integration. Focus on understanding VPN-IPv4 and VPN-IPv6 addressing, VXLAN overlays, and how EVPN carries MAC and IP routes across networks.
What is the format of the 4A0-114 exam questions?
The exam contains 25 questions delivered over 75 minutes in a proctored online format. Questions mix multiple choice with drag-and-drop and scenario-based items that test configuration, troubleshooting, and design decisions.
How does 4A0-114 compare to the 4A0-113 OSPF exam in the Network Routing Specialist track?
4A0-113 covers OSPF as an interior gateway protocol while 4A0-114 covers BGP as an exterior gateway protocol. Both are required for the Nokia Network Routing Specialist II certification. BGP is generally considered more complex due to its path vector design and policy flexibility.
What certification does 4A0-114 count toward?
This exam is part of the Nokia Network Routing Specialist II certification path. Passing it demonstrates your ability to implement and manage BGP in Nokia service routing environments and supports progression toward higher-level service architecture certifications.
What happens if I fail the 4A0-114 exam?
You can retake the exam after waiting a required period. Nokia typically allows retakes with a gap between attempts to allow time for additional study. Contact Nokia training support or your exam registration provider for the current retake policy and any associated fees.
How long is the 4A0-114 certification valid and how do I renew it?
Nokia publishes specific validity periods and renewal requirements on their certification pages. Check the official Nokia certification program details for the currency rules, whether renewal requires retaking the exam or completing other requirements, and any grace periods.
Can I take the 4A0-114 exam online or only at a test centre?
The exam is administered through proctored delivery, but the exact format and available testing locations depend on your region and the current exam delivery options. Contact Pearson VUE or Nokia training to confirm online proctoring or test centre availability in your area.
What job roles does passing 4A0-114 prepare me for?
This certification is aimed at network engineers, service provider professionals, and Nokia service router operators who design, configure, and troubleshoot BGP in production networks. It demonstrates competency for roles in network operations, design, or technical support for ISP and enterprise networks.
