  1. Which network management paradigm does Software-Defined Networking (SDN) primarily introduce?

    Answer: Separation of the control plane from the data plane with centralized control

    SDN decouples the control plane (decision-making) from the data plane (packet forwarding), centralizing network control via a software controller.

  2. A carrier is experiencing chronic fiber cuts along a specific route. Which protection scheme provides sub-50ms restoration on an optical ring?

    Answer: 1+1 APS (Automatic Protection Switching)

    1+1 APS in SONET/SDH rings provides automatic protection switching in under 50 milliseconds by simultaneously transmitting on both working and protect paths.

  3. What is the primary purpose of Network Function Virtualization (NFV) in modern telecom infrastructure?

    Answer: Replacing physical network functions with software running on standard servers

    NFV virtualizes network functions (firewalls, routers, load balancers) as software on commodity hardware, reducing reliance on proprietary appliances.

  4. A telecom operator needs to interconnect two data centers 200 meters apart within a campus. Which fiber type and connector standard is most appropriate?

    Answer: Multimode OM4 fiber with MPO/MTP connectors

    Multimode OM4 fiber with MPO/MTP connectors supports high-density, short-reach applications like intra-campus data center interconnects at 100G/400G.

  5. In the context of telecom network planning, what does the term 'traffic engineering' primarily refer to?

    Answer: Optimizing the routing of traffic flows to efficiently use network resources

    Traffic engineering involves optimizing how traffic flows are routed across a network to balance load, minimize congestion, and meet QoS requirements.

  6. Which protocol is used to distribute traffic engineering information in an MPLS network, enabling constraint-based path computation?

    Answer: RSVP-TE with OSPF-TE or IS-IS-TE extensions

    RSVP-TE combined with TE extensions to OSPF or IS-IS distributes link-state TE information and signals label-switched paths with specific bandwidth constraints.

  7. A CTE is assessing disaster recovery for a critical network hub. The recovery point objective (RPO) is set to zero. What does this require?

    Answer: Synchronous real-time replication with no data loss tolerance

    An RPO of zero means absolutely no data can be lost, requiring synchronous real-time replication between primary and secondary sites.
