Free Nokia 4A0-F10 Exam Dumps Questions & Answers

A subscriber installs several coordinated Wi-Fi access points to provide consistent coverage throughout a large home. What type of solution is this?

• A.  Virtual network function
• B.  Wi-Fi mesh system
• C.  DSL bonding group
• D.  Passive optical network

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 carries only voice services and does not support broadband data.
• D.  G.fast operates only over passive optical splitters.
• E.  G.fast requires a separate copper pair for upstream and downstream traffic.

Which of the following statements correctly describes downstream and upstream transmission in a GPON network?

• A.  Downstream traffic uses time slots assigned individually by each ONT, while upstream traffic is broadcast to all ONTs.
• B.  Both downstream and upstream traffic are continuously broadcast without coordination by the OLT.
• C.  Downstream traffic is broadcast from the OLT toward the ONTs, while upstream transmissions use OLT-controlled time slots.
• D.  Downstream and upstream traffic require separate optical fibers between the OLT and each ONT.

Which YANG node type represents multiple scalar values under the same node name without allowing child nodes?

• A.  Leaf-list
• B.  Container
• C.  List
• D.  Choice

In a GPON system using Dynamic Bandwidth Allocation, which device determines when an ONT may transmit upstream traffic?

• A.  Residential gateway
• B.  Optical line termination
• C.  Passive optical splitter
• D.  Ethernet aggregation switch
