Nokia Fixed Networks Fundamentals Sample Questions (Q11-Q16):

NEW QUESTION # 11
Which Lightspan interface type normally connects an access node directly to subscriber-facing equipment?

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

Answer: C

Explanation:
A User Network Interface is the subscriber-facing interface through which an access node connects to customer-side equipment or services. Depending on the access technology, this relationship can involve ONTs, subscriber ports, or other access termination functions. A Network-to-Network Interface connects the access node toward another network device, typically the Ethernet aggregation or transport network. A subtending interface is used when one access node is connected through another access node, allowing the downstream node's traffic to reach the aggregation network through the upstream node. A loopback interface is a logical interface generally used for management, routing identification, or testing and is not a physical subscriber connection. Correctly distinguishing UNI, NNI, and subtending roles is essential when interpreting an access-node datapath.

NEW QUESTION # 12
In a Lightspan High-Speed Internet service architecture, what is the role of the HSI VPLS on the IHUB?

A. It assigns Wi-Fi channels to residential gateways.
B. It switches HSI traffic between service forwarders and network-facing interfaces.
C. It performs DSL crosstalk cancellation on copper pairs.
D. It converts optical signals into analog telephone signals.

Answer: B

Explanation:
The HSI VPLS on the integrated hub provides the Layer 2 switching context used to carry High-Speed Internet traffic between HSI forwarders and the network-facing side of the access node. Subscriber traffic arriving through an ONT is associated with an HSI forwarder on the relevant line termination resources. The forwarder connects that traffic to the HSI VPLS, which then switches it toward one or more NNIs leading to the aggregation network. The VPLS does not perform optical-to-analog voice conversion, Wi-Fi radio management, or DSL vectoring. Those functions belong to different service components or technologies. This logical service architecture allows subscriber-facing resources and network-facing interfaces to participate in a controlled Ethernet forwarding domain while supporting the required service separation and policies.

NEW QUESTION # 13
Where should multicast traffic ideally be replicated in a bandwidth-efficient access network?

A. At the source once for every possible subscriber, including nonmembers
B. On every access port regardless of multicast group membership
C. At every receiver before the multicast stream enters the network
D. Only at points where the delivery path branches toward interested receivers

Answer: D

Explanation:
Multicast is bandwidth-efficient because one stream can be transported across shared network sections and replicated only where paths diverge toward interested receivers. Routers and multicast-aware switching functions use membership and forwarding information to determine which interfaces require a copy. This approach avoids sending a separate end-to-end unicast stream for every viewer and avoids flooding the content to subscribers who did not join the group. IGMP reports communicate receiver membership on IPv4 access networks, while IGMP snooping helps Layer 2 devices restrict forwarding to appropriate ports. Replicating content for every possible subscriber at the source would remove much of multicast's scaling advantage. Likewise, transmitting every stream on every access port would waste bandwidth and could expose receivers to large amounts of unwanted traffic.

NEW QUESTION # 14
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 operates only over passive optical splitters.
C. G.fast requires a separate copper pair for upstream and downstream traffic.
D. G.fast commonly uses high frequencies and time-division duplexing over short copper loops.
E. G.fast carries only voice services and does not support broadband data.

Answer: D

NEW QUESTION # 15
Which of the following statements correctly describes downstream and upstream transmission in a GPON network?

A. Downstream and upstream traffic require separate optical fibers between the OLT and each ONT.
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 traffic uses time slots assigned individually by each ONT, while upstream traffic is broadcast to all ONTs.

Answer: C

Explanation:
GPON uses different transmission methods in the downstream and upstream directions. In the downstream direction, the OLT sends a continuous stream through the passive optical splitter. This stream reaches every connected ONT, but each ONT processes only the frames intended for it. Encryption can protect subscriber traffic from other ONTs on the same PON. In the upstream direction, several ONTs share the same optical fiber and cannot transmit simultaneously without coordination. The OLT therefore assigns transmission opportunities using Time Division Multiple Access. Dynamic Bandwidth Allocation can adjust these upstream grants according to traffic demand and service requirements. Separate fibers are not required for each subscriber because GPON commonly uses wavelength separation to carry downstream and upstream traffic over the same fiber infrastructure.
