Q23. What is the primary function of the cladding in an optical fiber?

To convert electrical signals into optical signals

To keep light confined within the fiber core

To amplify optical signals over long distances

To divide one optical signal among multiple subscribers

Q24. Why must a managed ONT or residential gateway be reachable before an Auto Configuration Server can provision it using TR-069?

TR-069 requires an active management session with the device.

TR-069 writes configuration directly to a passive splitter.

TR-069 can configure only devices that are physically inside the central office.

TR-069 communicates exclusively through an OLT serial console.

Q25. What is a typical function of the Network Termination card in a Nokia Lightspan access node?

It provides external network-facing interfaces through faceplate connectors or optical cages.

It operates as the passive splitter in the Optical Distribution Network.

It provides Wi-Fi connectivity directly to subscriber mobile devices.

It terminates every analog telephone inside the subscriber’s home.

Q26. What is a key characteristic of software disaggregation in an access network?

Network software functions are separated into distinct modules with defined interfaces.

Every control and forwarding function is permanently embedded in one hardware appliance.

All network-management APIs are removed from the access architecture.

Passive optical splitters execute the access-control software.

Q27. Which transport protocol is commonly used to provide a secure connection for NETCONF sessions?

SSH

IGMP

ARP

SIP

Q28. In a GPON system using Dynamic Bandwidth Allocation, which device determines when an ONT may transmit upstream traffic?

Residential gateway

Ethernet aggregation switch

Optical line termination

Passive optical splitter

Q29. Which characteristic distinguishes G.fast from traditional ADSL technologies?

G.fast operates only over passive optical splitters.

G.fast commonly uses high frequencies and time-division duplexing over short copper loops.

G.fast requires a separate copper pair for upstream and downstream traffic.

G.fast carries only voice services and does not support broadband data.

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.

Q30. Where should multicast traffic ideally be replicated in a bandwidth-efficient access network?

At every receiver before the multicast stream enters the network

Only at points where the delivery path branches toward interested receivers

At the source once for every possible subscriber, including nonmembers

On every access port regardless of multicast group membership

Q31. A service provider combines two copper pairs to increase the available DSL rate for one subscriber. Which technology is being used?

Vectoring

Bonding

Optical splitting

Multicast replication

Q32. Which Wi-Fi 7 capability allows a compatible device to use more than one frequency-band link as part of the same connection?

Dynamic Bandwidth Allocation

Multi-Link Operation

DSL vectoring

VLAN stacking

Q33. Which Lightspan interface type normally connects an access node directly to subscriber-facing equipment?

User Network Interface

Network-to-Network Interface

Subtending interface

Management loopback interface

Q34. Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?

Optical line termination

Passive optical splitter

Residential gateway

Optical network termination

Q35. Which Corteca component is intended primarily for use by the subscriber during Wi-Fi installation and management?

Corteca mobile application

OLT network termination card

IPFIX collecting process

NETCONF candidate datastore

Q36. What is the primary purpose of Zero-Touch Provisioning for a newly installed residential Wi-Fi gateway?

To require a technician to configure every parameter locally

To allow the gateway to obtain its required configuration automatically

To prevent the gateway from contacting a management platform

To convert the gateway into a passive optical splitter

Q37. A YANG model specifies that a configuration leaf can contain an integer from 1 through 4094. What is the principal benefit of this restriction?

It allows invalid values to be corrected automatically by the optical splitter.

It enables configuration values to be validated against the defined data model.

It converts the integer into an Ethernet frame.

It prevents the leaf from being accessed through NETCONF.

Q38. An optical link experiences unexpectedly high signal loss immediately after a fiber cable is routed around a very tight corner. What is the most likely cause?

Chromatic dispersion

Excessive macrobending

DSL crosstalk

Dynamic bandwidth allocation

Q39. What does hardware abstraction provide in a disaggregated access network?

A consistent control interface across different underlying hardware platforms

A requirement that every access node use identical physical components

Elimination of all device-specific capabilities and operational limits

Direct conversion of every physical access node into a passive device
