Nokia 4A0-F10 Exam Syllabus Topics:

Section	Objectives
Topic 1: Fixed Networks Management	– Altiplano Software-Defined Access Network (SDAN) – Netconf/YANG and telemetry – NFV and SDN concepts
Topic 2: Home Network	– Wi-Fi fundamentals – Home devices and connectivity
Topic 3: Broadband Services	– Lightspan service components – Internet, IPTV and voice services
Topic 4: Introduction to Fixed Networks	– Broadband access fundamentals – FTTH, FTTx and FWA solutions
Topic 5: Access Network	– OLT functions – Access network architecture – Multicast and QoS principles

NO.18 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

NO.19 A QoS policy examines a packet’s markings and assigns it to a forwarding class. Which QoS function is being performed?

Classification

Shaping

Policing

Optical amplification

NO.20 Which architectural principle is fundamental to Software-Defined Networking?

Separating the control plane from the data-forwarding plane

Requiring every forwarding device to make all policy decisions independently

Removing programmability and APIs from network management

Combining all hardware and software into one fixed proprietary component

NO.21 A network controller must modify configuration data stored on a NETCONF-capable access device. Which NETCONF operation is designed for this purpose?

<get-config>

<edit-config>

<close-session>

<kill-session>

NO.22 What is the primary benefit of enabling IGMP snooping on a Layer 2 device carrying IPTV multicast traffic?

It converts multicast packets into unicast packets at the video server.

It prevents all hosts from sending IGMP membership reports.

It forwards multicast traffic only toward ports with interested receivers.

It replaces the multicast routing function performed by upstream routers.

NO.23 Which connection is normally used by a Fixed Wireless Access indoor gateway to reach the service provider’s access network?

An xDSL connection through a DSLAM

A GPON connection through a passive splitter

A 4G or 5G radio connection

An Ethernet subtending connection between OLTs

NO.24 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

NO.25 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

NO.26 A residential gateway ONT provides routed Internet access to devices in a subscriber’s home. Which DHCP role does it normally perform on the home LAN?

It acts as a DHCP server and assigns private IP addresses to home devices.

It acts only as a DHCP relay and never maintains address information.

It acts as a DHCP client for every device connected to the LAN.

It disables local addressing and assigns public addresses directly from the OLT.

NO.27 In a voice service delivered through an ONT, which component commonly provides signaling toward the operator’s SIP infrastructure?

SIP agent on the ONT

Passive optical splitter

Wi-Fi mesh satellite

IGMP snooping process

NO.28 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

NO.29 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.

NO.30 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

NO.31 What is the primary function of the cladding in an optical fiber?

To amplify optical signals over long distances

To convert electrical signals into optical signals

To keep light confined within the fiber core

To divide one optical signal among multiple subscribers

NO.32 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
