1. Which Lightspan interface type normally connects an access node directly to subscriber-facing equipment?

A) Network-to-Network Interface
B) User Network Interface
C) Management loopback interface
D) Subtending interface

2. Within the ETSI NFV management and orchestration architecture, which functional block manages virtualized compute, storage, and networking resources?

A) Network Management System
B) Optical Network Termination
C) Virtualized Infrastructure Manager
D) Virtual Network Functions Manager

3. What is the primary function of the cladding in an optical fiber?

A) To convert electrical signals into optical signals
B) To keep light confined within the fiber core
C) To divide one optical signal among multiple subscribers
D) To amplify optical signals over long distances

4. Which characteristic distinguishes G.fast from traditional ADSL technologies?

A) G.fast operates only over passive optical splitters.
B) G.fast carries only voice services and does not support broadband data.
C) G.fast requires a separate copper pair for upstream and downstream traffic.
D) fast is designed to deliver high broadband rates over relatively short copper loops, frequently using existing building or drop wiring. It uses a much wider and higher-frequency spectrum than traditional ADSL and commonly employs Time Division Duplexing. With TDD, upstream and downstream transmission use the same frequency spectrum during different time intervals. The upstream-to-downstream capacity ratio can therefore be adjusted through the TDD configuration. Higher frequencies can support greater capacity but experience substantial attenuation over distance, which is why G.fast is best suited to short loops. It does not operate through passive optical splitters, although fiber may be deployed close to the subscriber before the final copper segment. G.fast also supports broadband services rather than voice-only delivery.
E) G.fast commonly uses high frequencies and time-division duplexing over short copper loops.

5. How does an ADSL connection support simultaneous traditional voice and broadband data over the same copper pair?

A) It transmits voice only when no data packets are present.
B) It assigns voice and data to different frequency ranges.
C) It uses separate time slots controlled by a GPON OLT.
D) It converts the voice service into an optical wavelength.
