Nokia Fixed Networks Fundamentals Sample Questions:

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

A) 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.
B) G.fast commonly uses high frequencies and time-division duplexing over short copper loops.
C) G.fast requires a separate copper pair for upstream and downstream traffic.
D) G.fast operates only over passive optical splitters.
E) G.fast carries only voice services and does not support broadband data.

2. Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?

A) Optical line termination
B) Residential gateway
C) Passive optical splitter
D) Optical network termination

3. Which transport protocol is commonly used to provide a secure connection for NETCONF sessions?

A) IGMP
B) SIP
C) SSH
D) ARP

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

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

5. Why must a managed ONT or residential gateway be reachable before an Auto Configuration Server can provision it using TR-069?

A) TR-069 can configure only devices that are physically inside the central office.
B) TR-069 communicates exclusively through an OLT serial console.
C) TR-069 writes configuration directly to a passive splitter.
D) TR-069 requires an active management session with the device.
